ASUS P5Q3Deluxe will not boot, post beep, or even reset when pressing the button on the board. Is the board dead? if so how can it be I hardly used i.e. may be between 5 and ten time!

Welcome Newcomer!

A bad PSU, CPU or MOBO can present itself similarly; no beeps PSU or MOBO. To determine conclusively you would need a DVM {Digital Voltage Meter} ~$30 and test the PSU. If your PSU has either a reset or fuse then check that first.

Components fail almost immediately <5 days to approximately 30 days. My initial guess is either a Short or Bad PSU. A quick test is to remove ALL but bare components then remove ALL mounting screws leaving the MOBO to "dangle" - support with cardboard or towel and try to restart. If that works, hope it does, then remove the MOBO and use either electrical tape or plastic {non-conductive} to support the MOBO.

Otherwise you can breadboard the MOBO - remove ALL components out of the case and place the MOBO on cardboard, and assemble components for testing.

should help you go over things more thoroughly, but I also think its more likely either a short or psu issue at this point
