WIN 7- Processor causing computer to crash? (screen freeze when CPU at 100% on meter)

[food for thought]

so lately my computer has been freezing on me after about 15 mins of use

i noticed that my meter readings on the CPU and RAM have been higher than usual lately.

the CPU goes up to 90% and back to 40 - 50% then up to 95% - 100% randomly when im doing minial tasks like typing in this text box for example


i have tried closing all major processes and only leaving the browser open.

still freezes.

i noticed that when it freezes the CPU meter reading is at 100%


any thoughts about what can be casuing this?


CPU overheating due to dust and stifled ventilation is what i am thinking the problem is

[food for thought]

it just crashed again, this time it was at 96%

bump

so ive been using my PC for about 2 hours now with itunes playing and ive been on the internet a little. it hasnt crashed yet

and im using IE (usually use chrome) and my CPU meter is looking really good - going back and forth from 5% - 8%

I know Win7 uses a lot of the processor but that is far too high, do you have any programs running in the background?

[food for thought]

no i have been closing all other processes as soon as i boot to make sure i allocate enough of the processor to my internet browser or music (havent been playing music while i browse like i use to)
