Just an update guys, back on my computer now.
I normally do all the checkups and such myself but I took it into best buy and let the 'Geek Squad' do it. They did a great job and fixed the issue while saving me from buying another power supply. (turns out there was an issue with the way my CPU fan was mounted, must have slipped or something) They also cleaned everything up and even fixed an issue i had with the case for no extra charge. (seeing as the cost of the diagnostic was $70 I think they overcharge enough to begin with :P)
Honestly, if you're technologically inept, 1year of service from geek squad costs like $200 or smth and it includes a wide variety of things including an annual tune up. I'd reccomend it to someone's grandparents or something.
Most of all, thank all of you guys for your help. Cookies to all of you.
