random standby mode

[razorback]

Hi everyone,

I just replaced my old 300w PSU that came with a cheap case, with a new 350w Heroichi PSU that has higher voltages than my old one and also a bottom exhaust fan built-in. I must mention that this syste worked ok with the old one, or at least not having this problem. I startup, and maybe click one or two things, and it goes into standby mode by itself. If i make it to connect to the internet and get into IE (as i am now), it keeps flashing the "going into standby mode" dialog, about once a second. I have energystar settings set to Never on all categories, and have tried setting the standby mode to other values. I have cleared the CMOS and also tried clocking down to 800mhz from 1400mhz, but nothing seems to effect the problem. I checked the ATX power cable and all first, and different BIOS settings....it worked b4, and i dont c why it shouldnt work now, so if u have any suggestions, plz tell, and i will revert back to the old one if needed, but would like to keep this one if possible, without having to send it back. Only thing keeping it from going into standby is having IE open....once i close it, go bye-bye.. System config is :

Microsoft windows 98 First Edition
350w Heroichi PSU - all voltages stay up at proper levels
Shuttle Ak31 Rev. 3.1 w/ VIA KT266A chipset
AMD T-bird 1.4 -underclocked@ 800mhz 100mhz FSB
1 stick 256mb DDR PC2100 - tried more relaxed values, to no avail
Stick is in 1st slot
PCI geforce2 MX400 64mb - seems to get a bit hot , have slot fan beneath it. ( i also get visual artifacts during standby fits ) - first PCI slot

LT winmodem PCI - 3rd PCI slot w/ fan between vcard and modem
ATA 33 Quantum Bigfoot HDD - Primary Master
CD-RW - Secondary Master
ZIP Drive - Primary Slave

P.S. today is also the first real hot day of the season (80+)
but i also put a huge room fan blowing into case, with no effect, had temps to 83 F for processor, which heat came to mind as the first possible problem.....any help would b great! thank you!

Also, the new PSU is amd approved and seems to have plenty of voltage in BIOS.

Update : Forced APM 1.0 mode and disabled power status polling, which has stopped the standby fits, but has resulted in a "skippy" system performance. DxDiag loads alot faster for some reason, and runs tests ok, but it stutters about every 3-5 seconds. When i start TFC, the menu is turtle slow and takes a good 30 sec. to go between menus, havent even bothered to try getting into an actual game.... still, if you can offer any troubleshooting suggestions, plz do :P

Its not the temp if its really 83F.That's as cool as my Celeron, so for an AMD you are up there with watercooling!
Win98 1st ed. is very buggy!Some of the drivers weren't right so you might want to check that.Especially with an AMD chip.
Check your motherboard drivers and bios version.Test the power supply voltages for irregularities.

--Oh btw; I noticed; Overclocking.Tune it down a little as you're taking your chances anyway, especially with that OS!

well, it turns out that "Force APM 1.0 mode" is the thing that has "fixed" the standby problems, but has in turn created a very choppy performance, can't do anything demanding. I dont no anything about APM 1.0 mode , and why its slowing my system down so much? Any help? and what are you saying about overclocking? i was actualy underclocked to 800mhz then, but now i've decided to put it back up to normal speed. One time i was given the option to disable standby, but after i rebooted , it re-enabled, so if there's a config comand to disable standby all the time, then i would love to hear about it! thank you for your help. I have ACPI disabled in BIOS also.

That's the power management feature I think.
Try setting the power management setting all to never

never stand by
never HD
never monitor


never everything.

See what that does.

I think it is the heat. Maybe you shouuld get some artic silver and a better Heat sink and re do it.

There is no way your CPU temperature is 82F. I would believe 82C easier.

Try MBM5 motherboard monitor and see what temps that says. I re read the post and that temp is wrong. no way 82F on a hot day.

already have arctic silver 3 w/ retail heatsink, and heat is definitely ruled out as the issue...no chance. Now, it is narrowed down to a power management issue, as forced APM 1.0 mode creates a very stable, but very choppy system, especially with animated images displayed. I would like to re-iterate that the only thing that has changed in my config is the PSU, and i don't see why anything software-wise has changed......i will start jumping into the ol' switcheroo with my PCI cards and try ram in one of other 3 slots if nobody else has an idea of what's going on with my power management, or even better, disabling Standby mode in windows altogether....too bad Windows Help mentions nothing to help me, as usual.. should i enable ACPI support in BIOS and do a fresh install of windows 98? I never thought a new PSU would create such hellish software problems... could someone direct me to a hardware monitoring software that operates within Windows, that MDM or whatever you mentioned i believe is what im looking for. So at least i know that a huge box fan blowing into your case can yield some pretty low temps :P I also bumped my CPU voltage up one small notch just in case. Thanks for your input so far, but i am still left with a crippled system...

Try this and then post your CPU temperature.

Also you could switch the old PSU back to make sure it is part of the problem.

Ok, i got MBM 5 and my cpu temp is 98F and my voltages stay above the specified levels w/ case open. I also placed my PCI video card into the 2nd PCI slot and unplugged the extra fan to see if that helps, well, it didnt, its still wanting to go into Standby after APM 1.0 is disabled, except when working in IE it pops up every 1/2 second, but doesnt go thru with the standby. I took a second look at the power rail specs on the new PSU and some rails are 2x more powerful than the old. I was also thinking that maybe now the computer is too fast for 98 to keep up. Would the SE update provide a solution? Also , i noticed the only rail that is below spec is the +5.00 @ 4.95, which is basically on par. My CPU is getting proper voltage @ 1.79v. As far as power being supplied and heat, they are now both ruled out as the standby cause, to my knowledge the only thing left that could be the problem is Windows 98 itself....i really wanna play games and everything without this bull sheet.........wtf is up with windows?!

hmmmm, interesting twist....i put graphic acceleration down to one notch from no accel. and now it seems to work fine in normal windows tasks, but now due to acceleration being basically off, i can't run any games still.......now it seems to be a geforce issue or a monitor issue. Now it's been narrowed down to the video, but still i don't see why a new PSU would affect anything else... i tried to put it back to regular acceleration, but it goes back to being an @$$...

Lots of good nvidea stuff here

Hmmm... well i decided to go to microsoft.com of all places and i found that my random standby is documented and they have a fix : http://support.microsoft.com/search/preview.aspx?scid=kb;en-us;Q265115 Only problem is that you have to contact Microsoft for them to send you the fix!! how stupid is that... and from what i see, you have to pay them a service fee. I'm scouring the web for this fix, which is just what the doctor ordered...or im gonna see if someone has a copy of ME or XP i could use. Now at least that confirms im not crazy! If someone could get me this fix, you would be real cool. Later all.

Well, i found the file, but seeing as i am using Windows 98 first edition, and this is supposedly for SE, it may not be compatible? The file is on Compaq's site here : compaq (http://www.compaq.com/support/files/desktops/us/download/9191.html) It supposedly effects user.exe and user32.dll ... is it safe?
