I can't reinstall it. I can't do anything, really.
The motherboard page shows up for maybe a second if I'm lucky before the screen just goes black/loses signal. Putting in the disc does nothing.
Minor breakthrough, I was recording a video of the computer loading to show my problem when the F8 button actually worked for once. I entered Safe Mode and am now downloading Windows 7 again.
I'll tell you what happens after.
