I have a dell dimension 8250 that I've had for quite a while. Up until now I've been able to fix all of its problems but I was swapping out a hard drive and I accidently pulled out half of the power cord and the computer short circuited and it took about 5 minutes till I could boot it but when I booted it it couldn't find my hard drives at all. I've tried doing a forced IDE config I've switched the hard drives and switched the power supply. The bios menu still shows that I have all my ram. I've also tried taking out the little battery and vacuuming out my system and power supply. But I've only been able to get 2 hard drives found on a vista installation disk but it couldn't install onto them. And now it can't find my disk drives now.
I would really like to know what's going on and how to fix it.
