Computer BSODs a lot

[shalshal008]

First, I will start off with when my computer was working. I had Windows 7 and Ubuntu 10.04 running. Ubuntu asked me to upgrade my grub software, so I did, and when I restarted:

error: no such device: 148a517a-d27e-479b-ca6a71e05d23e7af
grub rescue>

I think I replaced one of Microsoft's registry files or something.

So, I completely erased both of my hard drives and then reinstalled Windows 7. I've been getting blue screens ever since. On top of that, my computer has trouble cold booting (overnight).

I'm trying to learn how to use WinDBG but I'm having trouble. I'm going to attach my .dmp files.

I will be very thankful if you could help me. I am also trying to do my best to learn so I'm open to anything.

Thanks a lot,
Chris
