PC not working when press power button

January 17, 2010 at 08:34:29
Specs: intel I7 950x58, pt6 motherboard, PSU 650,
I have just put together my first PC but when I press the power switch to turn it on I get a small twitch on the fans and the lights blink then go out expect the powerlight.

I did find HDD wires had been caught on the case and done some slight damage to the sleeve but I put some black tape around them but still have same problem.

anybody got any sugestions.

What HDD wires? You mean the data cable or the power cable?

Where were these wires caught?

Could be many reasons. Did you bench test the board before installing into the case?

Were you using everything new?

Are the components compatible?

List all the hardware including part numbers. Include the power supply model.

Lets start over!

Take the motherboard out and place on a non conductive surface. (cardboard or news paper)

Remove power supply and place next to motherboard and connect the 20 or 24 pin connector. Connect the 4 pin connector if a p4

Put 1 stick of ram in.

Connect monitor, mouse and keyboard to motherboard.

Don't worry about hard drives yet.

Plug power cord into power supply.

Using a flat screw driver...touch the two pins on the mother board you had going to the front panel on/ off switch.

May be a bit awkward but be sure power supply case is not touching the motherboard.

Does it start? Beep? anything?

If it starts....check the position of the stand offs in the computer in relation the mother board.

"I did find HDD wires had been caught on the case and done some slight damage to the sleeve but I put some black tape around them but still have same problem."

If this is the wires that come off the power supply and there not cut through tape is fine. If it's the flat gray ribbon cable, you may need to replace it as the wires going through it are microscopic.

This is secondary to making sure the board works.

Questions:
Did the board work before?
Did it come with the cpu already in?

Post back,
