open the case and check that the cpu and gpu fans are working...clear the dust out.

I have cleaned out the dust but to no avail....the fan does not seem to kick into high speed....

Does the fan on the CPU run at all?

 

[kenarly]

yes it does..

if there no video are there any beep coming from the pc at post...if there none..you want to try and round up a power supply and a video card. to see if one of those parts failed.
