for the past few months, my pc has been crashing quite regularly. it will either go to the Blue Screen of Death or simply randomly reboot itself. it will also reboot and be unable to display the "active desktop" (no wallpaper anymore). i've been advised by some to try MEMTEST. that program was no help. the first time i ran it, my pc simply froze. the second time i ran it, it did its thing for over 2 hours and never found a single error. any suggestions? i typically find that multitasking (launching browser, launching multiple windows in browser, video encoding, etc) will cause the problem. then again, sometimes it will simply reboot itself RIGHT after i boot it up. any insight will be greatly appreciated. thanks!
