a7v8x-x probs

[DesktopSolutions]

I have bought 3 of these motherboards recently. All three of them say no
emulation right under ATAPI CD ROM whe posting. It does not matter what is
pugged into the IDE ports ie. cd-rom only. 1 of them is working ok in a
customers PC but the other two seem to run for about a week with no
problems then the PC will reboot at any given time, power down right after
the post when going into the GUI, or run for just a bit then power down
having to turn the PS off.

When you do a fresh install (XP or Win98) it runs fine for a bit then
starts getting corrupt system files, games stop working, or rebooting on
its own.

I have installed win98se 2 times and Win XP Home 2 times so far. All of
the hardware is brand new:
ASUS cd rom, plextor burner, lg cd-rom, lite-on cd rom
amd 2500, amd 2000 cpu
maxtor 30 gig hd, WD 40gig, maxtor 60 gig plus9
sblive 5.1
abit gf4 64 4200
memory crucial 2100 256mb
geil 512mb 2700ultra.....which i know is not compatible now
corsair xms 512 2700 cs
corsair xms 512 2700 LL
2 generic power supplies
1 antec true power 430 psu
bios flashed to xxxx06
norton AV loaded and scanned daily

I have changed out all the parts more than once
Ran memtest86 for 24 hours....minimal errors or none at all
looked for compaibility issues
bought new hardware
AND lastly have an upset customer to deal with now.

Generic Powersupply? Maybe its causing the mobo to act wacky?

Did you install the VIA drivers? then the rest of the drivers like video, sound card, etc.


I'm narrowing it down the powersupply, mobo or RAM.

I suspect mobo the most.

Ooops, excuse my error below... I failed to notice it's the A7V8X-X instead of the A7N8X-X I'll leave the advice in case it gives you some ideas anyway.


Have you bumped the RAM voltage a little bit, 2.6-2.7 volts? "Minimal errors" doesn't cut it with memtest86, you want zero. Also, I'd suggest manually setting the memory timings to 2.5-3-3-7 instead of letting SPD configure it, since SPD may force the board to run the memory out-of-sync with the CPU's front-side bus. The memory and FSB should always be sync'ed on an nForce2 board (set the memory bus = 100% of FSB speed). Possible exception: a gaming system that's using the onboard video of an nForce2 IGP board.

And generic PSUs are more of a gamble than I'm willing to take, since I'm in the same boat as you... I have to support the systems I build, and I choose Antec TruePower330's (TruePower430 for my own work rig).

Other than that, check the PSUs to ensure that they're set for the proper input voltage for your region (110V/220V) and make sure the end connectors on your IDE cables have a drive on them, if there's just one drive on a cable, to eliminate signal bounce on vacant sections of cable.
