Hi all. I'm posting here because the hdd is most likely causing the problem. I put together a pc. Everything is new except the hdd, cd rom, and floppy. It turns on, i can get into bios, but if I don't choose to get into bios a few secs later I get this blue screen error- 0x0000007B(0XF78AE640,OXC0000034,0X00000000,0X00000000). It says that there was a problem and the computer has been turned off to protect from damage, etc. Then it gives the above number and says to check for viruses on hdd, check hdd and hdd controllers, and to remove any new hardware. I think that the cause of the problem is that there were too many hardware changes done at once or windows doesn't have the drivers for the new hardware. This is a hdd from my other computer, and right now I have Windows XP Pro installed. So, how can I fix this? I mean..I know there has to be a way to install a hdd from another computer. Thanks.
