I'm troubleshooting a friends PC who has recently brought a new PNY GeForce 6600 GT128mb to install into a L7VTM VIA KT400 motherboard He has no problems with his existing Geforce 4 MX 440 but the minute he swaps this to the 6600 GT the problems start..
1. No VGA Signal - monitor stays on stand by
2. No Bios Post - everything powers up but no Bios 'bleep' or activity at all
He has a good 500w power supply and has troubleshooted all the other hardware, If you just plug in the 6600 GT and remove everything else you still get the same problem. The bios has been reset and the card reseated, the power supply reconnected, the settings in the bios has been set to default and the Agp graphics aperture has been changed to 128mb.
frankly I'm all out of ideas... Can anyone help?
