unable to boot up or switch off

After a period of occasionally switching itself off randomly my p/c now refuses to either boot up or allow me to switch it off by holding in the on/off button. I have tried disconnecting the switch leads and shorting out the mobo pins for the switch with no result. The only way I can switch off the power is by switching off at the mains. Needless to say, there is nothing coming up on the screen. Can anyone offer any suggestions of the best approach to take for a cure? I have an Asus A7N8X mobo, 1 gb of memory, An AMD athlon 2400 cpu, 3 hdd's totalling 200 Gb, Radeon 9600 graphics card and a Q-Tec 500 watt power supply.

have you tried banging the computer a Bit?

Are you getting a Power Light on the front of the computer tower or is that not happening either?

If the Power Light is not coming on at all you may need a new Power Supply fitted.

Sounds very much like a failed PSU,

but If it will not boot how do you get the problem of will no switch off?

I think what he is saying is : It turns on but won't BOOT just stays blank? Then It won't switch off.

Well mate I think it's time for a PSU funeral and a visit to the shops or eBay or somewhere.
o.O

Yeah could be.

I am saying the above from Experience of the kinds of problem you suffer, but do not discount the PSU as these give some weird effects. Plus it's easy to test with another by just changing plug with PSU in bottom of Comp
