My computer shuts down after about 3 mins?

Forum CPU & Components : Power Supplies, Cases & Mods My computer shuts down after about 3 mins?

Every sort of 3rd time I switch on my computer the screen works. I know for a fact that the screen is not faulty as I tested it in other computers

Also after about 3-5 min my computer just shuts down randomly

Zalman 750w power supply
Intel core i7 920
6gb ddr3 ram

Why am i having power issues

When was it built?

Which Zalman 750W psu?

What mobo?

What OS? Fresh install or not? If not, where did the OS come from?

Did it ever work without doing this?
- if yes, what did you do before this started?
- if no, follow the steps here:

Now the moniter wont register at all.

When I start up the computer there is a long beep followed by 2 short beeps

One beep code table I found say for Award BIOS (which your board has), 1 long + 2 short beeps "Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information".

Check your manual, pages 33 and 66-72 for how to read 2-digit error codes on the mobo debug LED readout.

One thing to check: see manual p 52, configuring the initial video display. You must set here in the BIOS whether your video card in is a PCI or in a PCIEx slot. they are not the same - set it wrong and the BIOS cannot find your card.

What happened when you cleared CMOS? How did you do it?
