Hello there! This is the first time I find myself asking for help on an internet forum so I really don't know what to do any more. The computer was working until yesterday, ocasionally reseting (it had been doing that for a while, but it was once every two or three weeks) so I ran a virus scan, cleaned up my disk by uninstalling programs that I was not using and random files that I'd previously downloaded from the internet, but none of them were important for the system to function. After that I ran defrag and everything was working fine, the computer was obviously faster and I turned it off before going to bed. This morning however, it started reseting and I had two BSOD's in less than five minutes, and after the last one the computer won't work any more. It turns on but there's nothing on the screen, the fans work and there's no "beep" (it always does that right after I turn it on). Another thing I noticed is that the hdd (red light) keeps flashing in a weird way (it's not random as usual, it flashes with regular intervals). After it reset the first time this morning I tried to get more information to post somewhere but I got blue screens before I could do anything. I haven't installed anything in the past few days that would cause that and it doesn't seem to be a software issue so I hope someone here can help me find out what's going on. I'll post here my system specs: PSU Pixo PG-650 (650W) Asus P5Q Motherboard Intel Core 2 Duo CPU E6850 @ 3.00GHz 6GB RAM DDR2 800Mhz Corsair Nvidia GeForce 8800 GTX Windows 7 64bit Thanks for your attention.
