I think I can safely say my computer is fixed now, WOOOOOO! My friend helped me fix it, apparently my heatsink wasn't on right + my clockspeed was fluctuating like crazy. I haven't had a random cutoff in about a week though, so hooray! As a result I was able to finish the 2 MYOs I'd been working on and now I can get back to commissions!
