New system shuts down..:(

Hi

I have recently brought bits to make a new system they are as followed:

Speakers - Logitech S500 5.1 surround sound speaker system Silver/Black - OEM
Soundcard - Creative SoundBlaster X-Fi Xtreme Audio Soundcard - OEM
Processor - AMD Athlon 64 X2 4600+ Socket AM2 Dual Core (2.4GHz) 512kb L2 cache Retail Boxed Processor
Power supply - Coolermaster eXtreme Power 650W PSU - ATX 12V V2.01 120mm Fan 20+4pin
Ram - Corsair 2GB Kit (2x1GB) DDR2 800MHz/PC2-6400 XMS2 MEMORY CL5 Platinum Matched kit
Hard Drive - Seagate ST3500641AS 500GB Hard Drive SATAII 7200rpm 16MB Cache - OEM
Motherboard - ASUS Crosshair SKT AM2 nForce 590 SLI DDR2 SATA 8 channel audio ATX
Graphics Card - Point Of View 8800GTS 320MB DVIx2 HDCP PCI-E

Right, the problem i am having was at first the computer would boot up but there was no picture on the screen, but after a few minutes fideling about i pressed a switch that has “clr CMOS” wrote on it and then it booted up fine with the picture, However into about 2 minutes of it beeing booted up it will automatically shut down…

I have like 5-6 Fans in my pc running on highest speed but still shutting down.

Anyone have any ideas or solutions, would be great.

Thank You

The computer stayed on for longer a minute ago and it come up with a message saying “WARNING - YOU CPU FAN SPEED IS LOW OR HAS FAILED, YOU CAN DISABLE THIS MESSAGE IN THE SETUP”

I dont understand as i am using the fan that came with the CPU

Did you plug the CPU fan into the correct power plug? Also, can you get into the BIOS setup screen?

yeah, because no voltage is being return to the fan power plug, if your not using a standard cooler & plugged into the mobo, then you can safely disable it in the BIOS
