I had really hoped this was resolved but regret to say I think there’s still another kink in my system…
After finding an Intel Burn stable OC (20 passes on “Very High”) I started working on getting my two GTX 280’s working in SLI. The problem was that my graphics driver installs would only be good for 1-5 (one or two shut-down/boot-up or sleep/hibernation cycles) days before they’d become corrupted and various problems would arise (no 3d graphics on various programs, or even total rainbow crashes when booting to the desktop. Each time, I’d boot into safe mode, disable the secondary GPU then start the driver uninstall/reinstall process again with a different driver version. During this process, randomly (~10% of the time) I’d get a bad POST that would take me to the safe boot BIOS. When this happened I’d check settings to make sure it would boot with the settings described above then save and exit. It would then reboot just fine and I’d continue working on the driver issue.
After 3 attempts I found ManiacVVV’s “Ultimate Nvidia Driver Guide…” (http://www.evga.com/forums/tm.aspx?m=1174372&mpage=1
) I then followed that to the letter a couple of times with no luck (296.10 WHQL). Given the weird boot problems I dropped my OC to 1600 FSB x10 Multi (no voltage changes) Burn tested as above, and tried again. Again the drivers would work for a couple of days then go nuts and again I was seeing odd, though different, behavior. Rebooting when left in hibernation, very long POST’s or failed POST hanging in various spots (EVGA logo screen, eSATA detection etc.)
Finally I’ve dropped the OC completely and gone back to “auto” (still leaving the voltages set at OC levels) and I’m still seeing weird POST/Boot issues. When it boots up it seems to run fine, until the drivers get corrupted again. I have a brand-new copy of 64 bit Win 7 that I bought when I thought the problem may be software based, but I’m wondering if I need to revisit replacing my PSU or Mobo?
Short of grabbing my multi-meter (which I don’t mind doing I’m just not sure where/what to poke and what to look for) is there some way to tell? Replacing either is more than I’ve done to the inside of a computer in a decade though I’m still planning on building a new rig from the ground up next year…
Any comments or ideas?
