CPU problem... don't know what to title it

Ok, so, here is my comp

Operating System
MS Windows 7 Home Premium 64-bit SP1
Intel Core 2 Quad Q6700 @ 2.66GHz
Kentsfield 65nm Technology
6.0GB Dual-Channel DDR2 @ 400MHz (6-6-6-18)
SyncMaster (1440x900@60Hz)
E2040 (1600x900@60Hz)
1024MB GeForce GTS 250 (PNY)
Hard Drives
977GB Western Digital WDC WD1001FALS-00J7B1 (RAID)

i run this computer with 2 computer screens. I run the rockmelt browser in 1 screen, and I run chrome and World of Warcraft in the other. It has ran fine like this for 3 years (2009 pavilion HP) but about a month ago this strange thing started happening. What appears to happen is that the CPU starts being pushed to its limit, processing as much and as fast as it can, for no apparent reason... i tend to sit at a little below 4GB of memory being used when I have 6GB, and these little "seizures" are completely random.

Have you ever watch a streamed video or played an online game with poor internet connection? you know how jumpy and glitchy it was? THAT is EXACTLY what my ENTIRE computer is doing, it just does this jumping, lagging thing and if I have sound playing when the comp jumps I get nothing but a buzzing noise.

i used to ALSO have skype, ventrillo, and starcraft2 running in the background with no problem and now I am even having trouble running my basic set-up... anyone know what the hell is going on?

p.s. while typing this with just rockmelt, chrome, and World of Warcraft sitting there and doing nothing my CPU is sitting at 56 degrees Celsius, when it "seizures" it spikes to 62 degrees Celsius.

More about problem title
  1. Wouldn't hurt to remove CPU fan and reapply some new paste. Seems to be running hot. Have you cleaned the dust from the CPU heatsink?
  2. I have completely dusted it off, and that is a good idea I will pick some up tomorrow.
  3. Check the PSU. might be getting old, I have replaced at least one on my old HP Pavillion
  4. although that doesnt explain the random jumps in performance.... when it is doing this it it using in the upper 90s of its processing power... =/
  5. please explain why replacing the PSu would solve this.... i really do not know

    Cause it looks like you have replaced everything else and your GPU needs a minimum of a 450 watt PSU.@ 24 amps. Without knowing how strong your PSU is but I am guessing it no more than 400 watts.
