Computer not booting after overclocking...... please read its urgent

[Nutcase]

Hi. I overclocked my chip to 650mhz last night. I have a 433 Celeron. At first it booted and went into the windows loading screen and froze there which I had expected. So I rebooted and tried to get into the BIOS but I couldnt the computer would freeze before I could get to the BIOS. So I took the CPU and heatsink out. Put it on the table next to the computer. The sticky stuff on the bottom of the heatsink had kind of melted so I was worried. Now when I put the CPU back into the computer nothing happens. Any one have any Idea's why?? I put it in an turned the system on but all I can see is a blank screen. I didnt fry my chip did I??? I couldnt smell anything burning when I took the chip out and I did smell the chip. Please Help me......

Clear your CMOS. See your motherboard manual for instructions and the location of the jumper.

[Nutcase]

I tried to clear my CMOS.... it still doesnt boot. Any more suggestions?? I really hope the chip isnt fried or I am screwed.. Could the chip possiably have died?

[jmatrix]

Nutcase...first check to see if your heatsink is still making firm contact with the chip. If you can twist the heatsink back and forth a little, then it is not making good contact. I would recommend that you remove the heatsink from your chip and clean both surfaces very well. Check to see if the retaining clips hold the heatsink tightly to the chip. If yes, then apply some fresh heatsink silicon paste to the back of the chip and re-attach the heatsink.
Next...re-install the chip in the motherboard and don't forget to connect the fan power supply. Then, press and hold down your "insert" key and power up the system. With a number of motherboards, this will take you directly into the CMOS set-up.Make sure that you hold down the "insert" key until you see the CMOS set-up screen. If you're lucky and this procedure gets you to the CMOS set-up you should first load up the default settings, check for the CPU speed (try the default settings of 6.5 x 66mhz=433), then don't forget the "save" and exit. Oh ya, I almost forgot...cross your fingers.
Good Luck,
Paul

Good advise above but another item is to remove the motherboard battery. Take a break for an hour or so. Then put it back in and give it a whirl.
You may very well have fried something! though.

Hi, NutCase, I had same problem as you had. I had no idea how to fix it. Would you please post your progress. Thank you.

[jmatrix]

Nathan,
the "insert" key trick works in the three boards that I am currently using...Soyo SY6BB, Abit BH6, Abit BX6 Rev 2.
Here's the quote from the BH6 manual: "If you can't enter BIOS setup, you must try turning the system on a few times (3-4) or press "INSERT" key when you turn on and the system will automatically use its standard parameters to boot. You can then enter BIOS SETUP again and set up new parameters."
Good Luck,
Paul

Underclocked...How will removing the battery for and hour or so make any difference then if you removed it for a few minutes? I don't believe that the capacitors on the motherboard are that big to remain charged for that long.
Nutcase: How often do you remove your CPU? People have a tendancy to forget about ESD (electrostatic discharge). Be careful about how you remove electrical components and where you place them (like next to the speakers)and on what you place them on (laminated desks are great static electricity retainers). I am not saying that this is the cause of the initial problem, but it definately can compound a simple one. I know I had to replace several last winter due to techs mishandling CPUs and DIMMS.

[Underclocked]

Technically probably no difference at all and I should have told him to calculate the time required for discharge of his capacitors.
Glad you saw fit to correct my overstatement.

[Nutcase]

Umm... If I fried my chip then I will have to get a new one right? ****! Also the Insert thing doesnt work because... it doesnt display anything when I boot the computer. It is the same if I try and boot with a CPU or without a CPU. The moniter doesnt show anything. Any other idea's? Cause I really dont want to spend another what $150? **** again!

[scourge]

Is this a slot1 or ss7 chip? Take your chip out and make sure you reseat it properly. It is a rare thing to fry a chip.

[Nutcase]

Its a Socket 7. Check the connections? I tried that.....

[Nathan]

Jmatrix, what boards allow the "insert" key to be pressed to get into CMOS? Thanks.

[800XL]

Pull out the chip and look for any bent pins. If everything appears to be fine, reseat the chip. When you are closing the lever on the socket, push down slightly on the CPU to make sure it is fitting tight in the socket.

The most common thing I have seen with socketed chips is a scratched trace or damaged component right near the clips for the heatsink. Check around there to be sure nothing on the motherboard is damaged.

Reseat the dimms as well. Take everything but the video, RAM, and CPU out of the board including hard drive, cdrom, and floppy cables. Loose connections are much much more common than burnt parts.

... it doesn't display anything when I boot the computer.

Not even the graphics card power-on message that most graphics cards display. Normally no CPU is needed to get this message as it is part of the graphics card's initialisation sequence.

I would being to suspect power supply problems, either on the M/B or PSU itself. Have you got a spare PSU you can try/swap.

Assuming you have a power saving monitor how long does it come on for before switching into power saving mode (watch the monitor LED or listen to the clicks)?

I tried to disconnect everything and then tried turning the computer on. I still didnt see anything. The CPU isnt scratched and it sitting properly in the slot. I dont know of my power supply is messed up but I doubt it is because the cpu fan still gets power from the motherboard, Which in turn leds me to belive that the motherboard isnt bad either. I called Intel today and they said they can send a new chip. Can they tell that the CPU has been fried due to overclocking? Shold the video card display something even though the CPU may not be working? I have a Diamond Viper 770. Oh yeah and I have a ABIT BM6 motherboard.

Do the fans spin and stuff?
They should, even if there is no CPU or RAM.

[beevon]

I adjust the clear of cmos jumper. turn on and off the power then move jumper back to normal cmos. press 'insert' key and turn on the power again. it worked. Probably you can have a try.

[800XL]

After just setting up 8 machines with BM6 boards in them, one of them suddenly died. It was working, then it was not. The problem there was traced down to the motherboard. The CPU could be just fine in your machine as well. A dead motherboard could behave pretty much the same.

To get anything on the screen, you must have a working CPU, motherboard, RAM, and a video card. If one of those is missing or dead, you go nowhere. No video bios, no system bios, nothing. The only possible exception would be the video card. It is concievable the machine could at least begin to boot without the vid card, but you would not see any video for, um, obvious reasons.

I have not yet figured out what is wrong with the BM6 that died of crib death, but I suspect the bios is hosed or some component just gave out. I doubt I will even take the time though. Warranties are a good thing.


Sorry if we are bogging you down with the basic steps of troubleshooting here, but most problems are from the simple stuff. /forum/wink.gif If you have covered everything that has been posted here and are still not getting anything out of your machine, you have a bad apple in the box somewhere. It pretty much has to be one of the big four: RAM, CPU, Motherboard, or Video card. Any of those that you could swap out with a spare, or try in another machine would narrow it down. Just going from what you were doing when it stopped working, I would guess CPU or motherboard. I am leaning toward the motherboard personally, but I just had a BM6 die on me, so I may be biased. /forum/wink.gif

[AuraEdge]

I thought I fryed something last weekend..but one fan connector was loose. When thier partially on and not completely off or on, they wont start. I hadda rip out every part and reinstall each peice onces at a time to see what the problem was. At first I just tested that power supply and hooked up all the power connectors for the fans to make sure they spun up. Then I did Mobo power. Then I put in grafics card, CPU and RAM, and then found out that that one fan's connector was loose. Its real weird. When something loose and not seated in right, it wont start.

[Nutcase]

Well I called Intel and they said they can send me a new chip. Can they tell that the chip has been fried due to overclocking? I might be able to test my chip on another computer tommorow but I am not sure on that. I dont think the motherboard is messed up either because the video card heats up which shows that it is getting power. The ram also seemed to heat up; although the CPU did not heat up. With or without heatsink and fan. I will post my results tommorow on the CPU.

[800XL]

As far as I know, Intel has no way of knowing that the CPU was overclocked. I can imagine ways they might build a CPU to look for it, but I highly doubt they go to those lengths.

If Intel can swap the proc for you easy, go for it. I would get on finding a way to have the motherboard swapped if you can though. If the new proc does not fix the problem, being ahead of the game would help. Call the vendor you bought it from and let them know what is going on. They may extend the return period to see if the new proc fixes it, or they may be just as willing to swap out the board. If they don't want to be of any help start looking to Abit for help. You should be able to get one or the other to honor the warranty on the board for you. The reseller you bought it from is likely to be faster in getting you a new board though.

Anyone else think the video card could have gotten nuked here? If the AGP ratio was set to 1/1 at 100Mhz bus, that V770 might not have taken that well. If anyone else has some thoughts on that it would be helpful. I recall someone here having a vid card die due to 1/1 AGP settings.

[Susan]

Nutcase, I didn't see in your post whether or not you have heard any post beeps coming from the MB. Are there?

Anyone else think the video card could have gotten nuked here?

That should create some post beep errors...?

[Nutcase]

I will call the comany tommorow and see if they will replace the motherboard. And there arnt any beeps when I boot the system. Should the video card still display something even if the processor isnt working?

[800XL]

The video card will display nothing if the processor is dead. It takes a working processor, working motherboard, working RAM, and a working video card to get anything at all on the screen. If one of those four is dead, blank screen.

Not every video card failure will get beep codes. If you get beep codes, you know something is wrong, but in the absence of any beeps, it still could be anything.

[Pseo15]

i can help u with it. make sure the cpu is all the way in. it takes effort if u are using a slocket. u have to like push in real hard. If u have side clips like DIMM do, then make sure they are ttached.

[Roche]

hey nutcase!

I too had a celeron that I tried to oc with a Viper 770 also. And like you, I am using an Abit board (BE6 tho) and was having the same probs as you. Sometimes I could post and get into CMOS, but it would crash in there. The first thing I did was reset the CMOS through the jumper, didnt help. Then I let it sit (to think about what it had done wrong /forum/smile.gif ). That helped a couple of times, but it ended up that my vid card was messed up, maybe that is it. GOOD LUCK!!!

[darrell]

It could be the board thats bad. When I got my first Abit board, it was bad right off the start. It had symptoms the same as yours seems to. It wouldnt do anything. You really should check into swapping that out too if you can. It wouldnt hurt.

darrell

[Nutcase]

I doubt that the motherboard is bad because it was working before. The video card has been working for over 4 months now if it were bad then why would it quit now? I sent my cpu to Intel yesterday and I should be getting a new one in soon. When that comes in I will tell you guys what happens. Thanks for the Help!!

[CommanderC]

Well, the obvious thing to do, in my opinion, is to test all your equipment on another machine. Try the video, ram, HD, and even proccessor if you can find someone with a socket 370. I think it's video, sure sounds like it. But, as I said, you could test all of those pretty easy, exspecially since it looks like you have another cpu.

[Plaster]

I read on another UBB that the Video card fried the MB. If I recall correctly, it was a Xentor TNT/2 and a BM6 MB. The TNT/2 drew too much voltage from the AGP slot and eventually fried the MB. Isn't the Viper V770 a TNT/2? Anyway, just a suggestion. Look into it.

[BMF]

Nutcase. Well, your video card may have worked before you overclocked, but when you overclock a processor, it also overclocks other components of your computer (like video cards). I don't see how it could totally fry the card, but anything is possible, especially with the amount of overclocking you did (from 433 to 650Mhz). Also, did you overclock it directly from 433 to 650Mhz, or did you do it in small steps. It's a good idea to overclock in small steps and not just drastically jump from one speed to another. Not only does it "burn in" the component slowly (i don't know if that's just myth, but I think it makes sense to me), it'll also let you see your exact overclocking limit. Who knows, maybe with your amount of cooling you could only overclock to 550Mhz. Just some advice for the future, considering that doesn't really help you now. I dunno, any one of your components could me malfunctioning. You may want to bite the bullet and just send in the whole computer to where you bought it for repairs, or to a repair shop. They may have a better chance at fixing the problem.
