So I'll try to keep this quick:
On Thursday of last week, @Soda
and I installed a new hard drive for my pc (secondary to my SSD with windows on it). After installing, for some reason, while the computer would start and appear to run correctly, nothing would happen on the screen. We checked the screen and the PC with another screen, and the same thing happened; it was the PC, not my monitor.
Soda reseated my graphics cards and futzed a bit, and then magically this problem was solved. We were not sure what the issue was to begin with.
I got home yesterday, and found my graphics card FLOATING in my PC. (Note: Graphics cards are not a flotation device. Do not grab one in case of water landing). Apparently one of us forgot to put the screws back in that hold it in place. After my hysterics ended, I reseated my graphics card and booted it up.
It worked! Except it said that I had a disk drive failure. I turned off the computer, and attempted to boot into bios. Now, it would not boot, and started doing the thing when the computer starts, but the screen never turns on.
Additionally, and this may be the most important part: when I turn it on, it will restart at least once, possibly twice, before it gets going in earnest. This is actually not a new problem, it's been doing that for months. So perhaps it's the power supply?
Help me obi-wan icrontobi, you're my only hope.
