I recently installed a new CPU, AMD Phenom II x4 965 BE and i overclocked it to 3.9ghz and it normally runs around 40C to 50C. this made me want to go back and try to see how much better this could make my very heavy games such as GTA 4. I took the settings to as high as possible just to see and there was tons of lag as was expected. After i left the game i noticed programs such as Steam had weird graphical glitches that i had never seen before and Chrome was crashing every time i opened it after about 10 seconds.
Now when ever i try to play heavy games such as Hitman Absolution i have to reboot my computer so the instability of my system would go away. Im also getting errors from SpeedFan such as stack overflows for low cpu voltage and a gurgling sound mixed with a muffled dot matrix printer from my computer case that id never gotten before that fateful night i tried to play GTA at full settings.
Did i ruin something in my computer by playing these heavy games and if so what could it be?

sorry for being unresponsive. School caught up with me.
I changed my clock speed back to stock and the stability has increased. but the gurgle sound came right back as soon as my desktop showed up. I'm starting to think its my older hard drive going bad. (4 years old) im not sure of the life span of a WD HDD though.

A hd death rattle you have ! get a replacement before you start getting chkdsk errors on start up.
Grab a free copy of xxcopy it will clone and mount the new drive for boot.

Good Luck !

thanks. I have been getting check disk errors. I have a 1TB HDD and my windows installation is on my 500gb hdd. would it be easy to transfer everything on my windows hdd onto my extra one with that program you mentioned? also could this failing hdd be the cause of my system instability even though my games are my extra hdd?
