I feel the cpu section may be a problem

If to change the power supply ?

Power all ok. I suspect the bios i need dump from workin laptop anyone have pls upload

Check what type of CPU installed. Some motherboard revision work only with Intel Celeron M 530. Try with Intel Celeron M 530. If processor has been replaced to another (at example Intel Core 2 Duo T7250) you have problem with integrated video after Power on. If you go in bios settings, F10 and save, after this reset win7 starts ok. If you work with ext. monitor the win7 starts ok after power on.
with windows Xp: bluescreen
with windows 7:photo

or try Celeron M540 (FSB 533Mhz)

maybe overheat?

Hello
The problem was with the 965 graphics as the pll voltage 1.25v would drop after the graphic chip heat as when windows load it would put more load on the intel integrated graphic chip
Thanks all for replying it was a coincidence with 2 board same fault
