My stupidity often overrides my logic. It is just me. It cannot be explained. This is a prefect example of what NOT to do when messing with your CPU.
Back in November, about a week before my birthday (I do the same with Christmas), I went on some sites with my dad's login, and found out what I was getting on my little day. One of them was a Thermaltake Blue Orb II CPU fan I had asked for. Upon opening the box and acting as surprised as possible, I found that the thing was about 1 CM to big for my case (it was a small form factor case, and I didn't take the time to measure it). So waiting another week and after receiving the case, I continued to attempt my new case swap and fan replacement. I spent 4 hours getting 2 little standoffs out of the legs that attached to the motherboard (this made the heatsink + fan too high, not touching the CPU, and thus emitting a siren-like sound upon boot, followed by an emergency system shutdown).
After getting that done, I screwed the heatsink into the slots, and booted it up. Success! It works!
Coming to about 4 hours ago, I was testing my system boot time, and noted that it took longer than usual to boot. I went into the BIOS and changed the hard drive to the primary boot device; but I also decided to take a look at the system fan speeds and temps.
CPU temp 67C
I about wet myself- 67C?!?!?! Thats roughly 153F!
After thinking for about 5 minutes what could be causing the heat problem, I remembered that I, for whatever moronic reason, did not apply thermal grease to the CPU!
I kept it in my drawer of computer supplies, so I pulled it out and got to work disassembling the thing. After 45 minutes of work, I plugged everything back in to find that it would not boot. Another 30 minutes of troubleshooting revealed that if I remove all USB devices, it boots (I have not yet rebooted with them plugged in).
With the new fix, the computer seems to run a little faster and a little cooler, although I am going to stress test it for the next few hours on some of my games.
Moral: Follow instructions- not your stupidity
