So I've been having a lot of client and computer crashes lately whenever I play World of Warcraft or run Prime95 + 3dMark05. When it crashes it just goes to a blank blue screen and reboots. Everyone I've talked to says it's probably my ram. I've got Mushkin Pc3500 2x512 BH-5 that's been run at 2.9v and 228mhz for around 2 yrs. I've run memtest86+, no problems. However, it seems like the crashing stops for a while if I swap the modules between their memory slots. Any ideas or other tests I could run?
