Last night I purchased a new Coolermaster case to improve airflow and the overall look of the computer. I am somewhat novice at this but I understand the basics and have friends to ask for advice, so after a couple hours I have everything in the new case and I go to power it on but - no dice. I check all my connections and everything seems ok but it won't power on, so I take it all apart piece by piece and get my motherboard alone so I can see if I fried it. I am still having trouble powering it on but it seems to power on occasionally when I try. Very confused now so I take off my heat sink, dust off the processor, replace the heat sink and now it's powering on regularly.
Now I put everything back in the case, hook up all my components and boot it up. Boots up great, the computer is working like it was before I moved over to the new case, great. After checking a few things and making sure sounds, graphics card, and internet work - I go back to life as usual. Watching a few hours of netflix when all the sudden boom, the system shuts down and won't boot back up.
After working on the thing for about 5 hours I just didn't have the motivation to try to fix it last night. Figured it might have been heat related so I leave it and go to bed. This morning it still won't boot and I'm completely lost.
