Dual Processor


Hi Peoples,
I have a Pentium 4, 3.2gh, 1.5gig ram, nvidea gt6600 graphics card, 200gig hdd, dual processor.
The fan on the processor speeds up and is fairly noisy slow fast slow fast so on.
It mainly does this with graphics but some times with downloads.
When playing games like GTA and Battlefield2 it really revs out even when a game is paused and then after awhile it goes to the blue screen memory dump process then restarts.
When you first start it up and put a game up it takes about 5minutes to jam then after that more frequently.
It also makes the graphics and video playback jolty as if it can’t keep up.
All the components are new.
Does it sound like the processor is at fault? As I’ve never had anything to do with dual processors before so any info would be good.
I don’t know what to think I’ve formatted and played about but no good.
Any suggestion most appreciated.
Cheers
