P{C chip help

[Marky78]

I have a Asus A7V266-e with a AMD 1.3 GHz Processor, the problem I have is that it wont boot up.

I mean it wont power up the monitor and come off low stand by mode.

I phoned up my supplier and they said try setting it as 1.0 ghz AMD, by using thes settings Multiplier 10 x
CPU Core voltage 1.75 v
and FSB 100mhz

This will still not make it boot and reach bios

It isn't give out any bleeds through the pc speaker.

Have you got any ideas as to how I can make it work.

I have worked out it could be eiether a faulty motherboard, or CPU, is there any way to test to find out which one it is.

I cant get my hands on another AMD chip.

Thanks in advance for your help.

Mark.

Could be anything with the description you have given.

However, some checks that might help.

First sound, do you hear any fans whirring? any noise at all?

Second light, does the LED on the floppy light up, the HDD light up at all?

If you open your case, can you see any fans moving when you power it up?

Please check the simple things first. You need to be sure power is getting to your pc,(you havn't just blown the fuse), then once you are sure that the power is getting to the pc, you now need to be sure that pwer is being given out by the power supply unit. So no fans working would suggest no power distribution.

I would recommend you make sure all your cables are firmly in place and that all your cards are fully seated, including memory.

Tell me, what was the last thing you did before the monitor failed to power up?(eg load some software, install new drive etc)

[Marky78]

Both the power supply fan and processor fan start up and the green led on the motherboard lights up.

The HD light and floopy drive lights do not come on, and there is no warning bleeps from POST. as I dont think it is doing the POST.

Is this a machine you are now building or is it an already established and running machine?

Try clearing the cmos.

Also are the speaker wires hooked up to the right header on the motherboard.

SPEEDO

[Marky78]

I Will try clearing the CMOS again.

the Speaker as far as I Can is connected to the right mobo connection.

It is a brand new system never been used before.

The ASUS website says I need to flash the BIOS to allow for Duron 1.3 GHz jumpfree mode so I am using jumper mode
with the CPU core voltage set at 1.75 v Mulitiplier 10x and the FSB set at 100 mhz. (this was told to me by my supplier of the mobo and chip.)

[Marky78]

The system is totally dead, it wont even power up the monitor.

I have cleared the CMOS memory again and still it doesn't work.

How can I tell if I have a faulty motherboard or CPU?

[SPEEDO]

Double check the ram to make sure it is in all the way.

Do you have the cpu fan connected to the proper header?

SPEEDO

[Marky78]

I have the fan connected to the correct header.

and I have tried two different types of Ram in all the mobo dimms.

[Ammok]

Physically check the cpu for damage. Is it a good one? ie, one that has been working before? or is it just new?

Some mobo's have protection on them to prevent misuse if the fan is not connected properly. However, so far, it is highly probable that the cpu or mobo, as you suspect, are causing the problem.

Please double check your jumper settings, the cpu sometimes won't boot if the settings are incorrect. Perhaps reduce them to 100 x 10 to be sure and see if you get a post. IS there a "switch" jumper to enable onboard jumper settings?

[Marky78]

The chip is also brand new and never been used.

It has a jumper to enable jumper mode which is set to jumper mode enabled.

I have the CPU jumpers set at CPU Core 1.75 v Multiplier 10x and the FSB set at 100 MHz.

and I still get no POST or monitor power up.

How can I tell if it is the CPU or motherboard?

Also the mother board is sat on fibre washers then it sits on the stand offs.

Does the motherboard earth though any of the mounting points?

[Ammok]

It is possible, but unlikely that the mobo earths through the studs, it can simply use the power supply return. Perhaps worth a try seeing as your are desperate.

Like you, i think it has to be the mobo or cpu, only problem is you can't really check either without another one to plug the cpu into.

But as power is being distributed, mobo led comes on, prime suspect has to be cpu. You really need to plug it into a known working board to know for sure it is a good one.

Any freinds, workmates, aquaintances willing to try it out for you? beg a little, or a lot? Local shop test it for you?

[Ammok]

ps. try it with jumper mode disabled

[Marky78]

I have tried it in jumper mode disable and still no POST or BIOS :(

I am the only person I know with a AMD chip, :(

I will have to ring my parts supplier again and get something sorted, before the weekend.

Thanks for all your help. :D

[HorsinAround]

Try removing everything from your board--HD, video, sound,modem,printers, even keyboard and mouse. See if it will POST. Should get beeps if it sees ram. If it does plug them in one at a time. If it doesn't try new ram, reseat in all the slots. Then pick up the phone and get nasty! Your supplier should take the board in for you, test it, and or give you a new MB. I have been this route before Hang in there! Good Luck and keep us posted, pardon the pun!:D

[Marky78]

I have just tried it with the graphics card removed and I still fail to get POST or hear any bleeps.


My supplier has said top me they have sent loads of the ASUS A7V266-E back to ASUS as faulty, so they are willing to send me a new Motherboard, they have recommended ABIT to me.

Are they any good?

[Ammok]

I got abit sound card and abit video G2.

Both came with decent software and work fine, the sound card is excellent.

I have only ever bought MSi motherboards though, so can't give you any help there.

[SPEEDO]

One more thing to try.
If you are going to take it out of the case anyway.
Put the motherboard on a phonebook or something.
Hook up just the following items.
Power Supply
Ram
CPU, Heatsink & Fan.
Video card.
Wire from the on/off button on the front of the case to motherboard.
Speaker wires.
Plug the monitor into the video card.
Plug the power supply in and make sure the rocker switch on the back of the power supply is on.
Hit the power Button.

Good Luck..:)

SPEEDO

[Marky78]

Still didn't work :( I waslying it on my motherboard box. ;)

All I can do is wait for my new board now.

I think it is a ABIT KG7- RAID, are these boards any good ?

[Marky78]

My new board came today it has the same problem. :(

I have been told that the AMD Duron 1.3 GHz requires at least a 300 watt power supply.

Could my supply be at fault and how do I test it to make sure it isn't at fault.

What wattage is this PSU is it 280 watts!?!? :confused:

+ 3.3 v & 5.5 v Combined load 175 watt
+ 3.3 v & +5 v and + 12 v combined load 280 watt 3.3v 20 A max, + 5v 26 A max, + 12v 13 A max, -12v 0.8 A, - 5v 0. 5 A max, +5v sb 2 A max.

[Ammok]

Honestly. Marky, all you have done so far suggests a mobo or cpu fault. Now you have a new mobo, and you would have to be extremely unlucky to have two faulty boards from two different manufacturers, everything now points to your cpu.

I do not know your level of expertise, but all I can suggest now is a new cpu. You really need a working cpu to test your mobo and setup. If it is power supply related, not putting everything in will help you get a post, eg just mem, hdd, cpu and vid card will boot.

To give yourself some peice of mind, rebuild your system along the advice given already, from scratch, and see if this makes any difference, but if it is a duff cpu you will still have nothing to show for it.

Can you buy a cheaper duron just to see if it boots? 1ghz and under are really cheap at the moment.

[Marky78]

Okay! Thanks for your help.

Will try getting a new CPU, would a faster chip work ok? or is it best to go slower?

[Ammok]

Looking here

http://www.motherboards.com/catalog/product_info.php?category_id=4&index_id=7&subcategory_id=7&products_id=398&

it looks like it will support Athlon to 1.3gh but only 950 on a duron.

it may be a good idea to drop the fsb to 100 and the multiplier to, say , seven and see if it boots.

[Marky78]

Thanks :D

I am begining to hate this supplier. On Tuesday if I haven't got it working I am going to phone them up and get them to pick them up, and refund me.

The ABIT motherboard has no jumpers only one to clear the CMOS memory, and I have cleared it.

Do you think it could be that my power supply isn't good enough to supply a 1.3 Ghz Duron?

All I have plugged in and working is the mobo, chip, ram, Graphics card and CPU fan.

and still no boot on ABIT and the ASUS motherboard.

marky

both boards should at least power up. The first board showed power up led's as being on, so I don't think that the power supply is your problem. Usually, a power supply problem is that the power supply don't work. If it was a wattage problem, that is the psu was too weak to support the power drain, the puter would still boot but suffer random crashes or other insane happenings.

So as not ot insult you, and I do only mean to offer help, can you tell what skill levels you have. I have built and upgraded a dozen machines, am very good with applications, but not half as knowledgeable as some of the members here.

For example, if we can figure out the problem being the mobo, you can post a new message on the mobo forum and some of the residents there will help us out. probably with more experience too. My problem is that i do not know where to refer you too next. If you were a complete novice, I would go through each step you took little by little, because the problem would most likely be inexperience, with a good chance the equipment is good. If youhad built a dozen machines all fine, then the problem would be the cpu or psu, as you suspect.

I do not think your psu is the root cause of the problem, unless it is totally faulty, and you need a megaohm multimeter to prove that, or the famous "other known good" psu.

Saying that, people do buy new and the items do prove to be faulty. Every million cpus has to have some duff one in there somewhere.
