I just built a computer and am having a very annoying problem, where if I am downloading a file, or un-archiving a file, my computer suddenly stops responding.

My screen image is still visible at this time ,my mouse movements are still registered, and buttons still depress when clicked on screen, but no reply.

From what I hear since im using 10k rpm raptor, my Hard Drive is not running at this time, but it may also include others that I cant hear.

My CPU, MCP,and Motherboard are below 50 Degree Celcius

After about 1 minute my computer will begin working again as if nothing happened, but if the item is still downloading, the computer will go back into this mode within 20 seconds.

From what I see there are no loose connections.

Here Are the specs of my comp:

Vista Ultimate(It is legal)
Evga 680i Mobo
Evga 8800GTX GPU
Intel QX6700 CPU
Intel Stock 775
WD Raptor 150g
Thermaltake Armor Series VA8003BWS

I dont think that it is fault of my power supply because at this moment they do not decrease in speed, but just in case, it is A thermaltake ToughPower 700w

Please note: I dont know Temp of Hard Drive

Please help, due to this problem My computer is downloading VERY slow,
Please respond soon.

Thank you for your time.
