Hello all,
My computer has been running fine, but went completely unresponsive yesterday for no known reason, and my headphones played a loud beeping sound. I force shut down my computer and restarted and the same thing happened ~4 hours later. Again I restarted my computer and ~2 hours later my computer bluescreened. I let it sit for a while in case there were cooling problems then tried to start it again. The system started, but there was no monitor output. All of the fans were blasting at full speed. I heard the hard drives start to spin up but my drive activity light never turned on. Any suggestions/tips?

Specs:
CPU: Q6600, probably ~3-4 years of use
Mobo: From a stock dell, no clue how old
GPU: geforce 9800 gtx, ~3-4 years of use
RAM: 8 gb whatever ddr2
PSU: Antec whatever

Thanks,
D35TR0Y3R

Edited OP. Last cleaned when I put in this mobo from a different computer, a few months ago. I don't have an i/o backplate so there could have been some dust buildup
 
I'm going to start with suggesting a physical cleaning with an emphasis on the PSU and VRM area and take the graphics card out to clean it real good. After that, reset your CMOS clock. See if that doesn't help.

edit: While inside, look at the capacitors on the motherboard to ensure none appear swollen or leaky
