Hello, so here I am after I upgraded my PSU and GPU. I took some recommendations from people on here, purchased the parts, and installed them into my computer myself. Fast forward a month and I upgraded to windows 7 from XP. Now every once in a while when I am not actively using my computer, say I leave it on while I use my Xbox or go and do something else and leave it on, I'll come back to see it at the login screen and I'll log in and it'll say it recovered from and unexpected restart. I don't normally leave my computer on when I'm not using it or near it. So it'll do this after about 20-30 minutes of sitting Idle would be my guess. Which come to think of it is when my screensaver is running, which is a custom one I got from the internet featuring the matrix code falling down the screen. Damn, could that be it? Anyway it was never a problem until yesterday when it restarted itself and all my programs in the Programs(x86) were wiped out. I.E. the folders are there but they are completely empty. Sorry for this being so long just trying to be thorough, here is my specs: Windows 7 Intel Core 2 Duo E8400 @ 3.00 GHz 4Gb Corsair RAM HIS Radeon HD 5770 750 Watt Corsair PSU Gigabyte Motherboard Anything else just ask. Help would be greatly appreciated. Edit: Also rarely when I hit the power button to turn on my computer when it's off it'll make three rapid beeps and the display won't come on but pressing the power button to shut it off and turning it back on fixes it.
