okay...sorry for the informal IT language, but i'm not very computer orientated, but i will try my best. OK...firstly i have installed a fresh copy of windows, everything worked fine, then i installed my drivers for some chipsets and for other parts, after this installation, my computer restarted by itself. Now for some reason, the computer runs, sees 2/2 hard drives when it first boots up, then after the windows professional page comes up, the blue screen comes up for like a split second before it resets. I have tried changing the settings in the bios section which has made things worse. Now after the startup, my usb mouse and key board aren't fuctional. they turn on for like 5 seconds then switch off and have no function having had this trouble i decided a possiblity would be to install a fresh copy again onto one of my hard disks, but when i install the windows, it says it cannot find my hard drives as they aren't any. but when windows start up, it can see my hard drive. and also one more change, it says my SMART capability is disabled, which usually is enabled :S. please help asap. Cheers okay to make it clearer if at all, now my computer practically runs, sees harddrives only on startup, then does not see them after that, and windows logo comes up with the little green bar that scrolls left, and den the blue screen of death comes up. it has all this gibberish writing on the blue screen of death and then just restarts. i have tried installing windows fresh but it says i have no hard drives. any questions i'll be glad to answer. cheers.
