So ive been troubleshooting for a friend for a while now on a strange problem that has been happening to his new comp. Every once in a while, sometimes a couple times a day while playing WoW, his computer just reboots, sometimes you see a blue screen first. One time he saw an error that had ati in the name is why im posting here. The new comp is a Gigabyte GA-MA790FX-DS5, Radeon 3870 (i think Sapphire, 2 slot cooler), 2Gb ram G. skill I think, Phenom 9600, cant remember the PSU atm but i think its over 700w. Sorry if some of the info is incomplete as I cant see the comp first hand, helping him over the net. Put in new drivers 8.4, updated the bios and made sure the TLB erratum bugfix was enabled along with defaults loaded, windows up to date (winXP) with all the software stuff, but not the hardware. It still appears to be doing it though. I told him to test some other games, will have to see about that, but it doesnt happen often enough to reproduce easily. Does something like this sound familiar to anyone? Thanks in advance.
