x2 Sudden Instability

post #1 of 8
Thread Starter 
Folks,

I recently did a clean Win XP install and put in an A64 x2 on my main rig. After that, all hell broke loose.

I have installed the most recent drivers for the sound, video and chipset. I have also installed the x2 drivers, but not the optimizer and MS hotfix.

I am getting a lot of "stop" errors, one IRQ (you know which one I am talking about), and a kernel stack one.

I have ran Memtest+ on my memory, both sticks and individually for 10 hours+ without any errors. I have ran Prime 95 for 8 hours without a hitch. Yet I am still getting the "stop" error, which always points to a driver, but never tells me which one.

I am about to throw this POS x2 out the window and put the San Diego back in. Help me out, will ya?

put the san diego back in and see if you have any stop errors. if you do, it's the installation of windows or your hard disk or graphics card or motherboard or SOMETHING, but it's not your CPU.

iTry the other CPU. Since you installed a fresh set of windows the the CPI there shouldn't be a hitch. The CPU being the cause seems unlikely because it usually cpu problems are very easy to catch, like your computer not working at all .

Try getting the most up to date drivers for your stuff and update your BIOS just to be sure.

I'd assume your board is dual core compatible too?

I followed my instinct and just went ahead and changed the PSU. Instability is gone. Now that I have a more solid PSU, I went ahead and installed a second 7900GTX too. No instability to speak of. But can't make Steam work... sigh.

Crash to desktop with looping sounds, games just not starting...

I have used all the solutions offered at the Steam forums and nothing.

Do any other 3d applications work? If not I'd try without the 2nd 7900GTX. I think I've had that problem with steam before where the title screen wouldn't load and the games would just crash, but I forgot how I fixed it . I believe I did another fresh install of Xp again though.

I'd also try a 3rd party Nvidia driver if nothing else.

It happens with one card, 2 cards or in SLI. Other 3D apps work flawlessly. Using 3rd party, Nvidia or OEM (the ones that came with the card) result in the same.

Anyway, this not about cpu instability anymore, so lets stop.
