hey the other day i noticed a file that i didnt download in my download folder. so me being a ***** clicked it without anti-virus up, and i got a bsod. i tried going into my bios to reformat my hdd, but its not there, memtest is not working for me, restoring windows caused it again, and it froze up backing up files then trying to restore. Currently im running Ubuntu off a disc, so i dont think its a hardware problem. I do not know what to do. heres my specs if it helps: Athlon X2 II 2.8 GHz 4GB RAM DDR5 XFX ATI HD Radeon 5770 1GB 640GB HDD Windows 7 Home Premium Can somebody please help me?
