I have just moved house and the pc mistakenly went in the removal van, upon connecting all seems to be ok, single beep from bios, but cannot get any display on the monitor ( which is working when connected to laptop). I've changed the cmos battery, reseated memory modules, video card and usb card, and also fitted a new psu as I know it was not working properly before hand. When rebooting, I've held the power button in, both switching on and off. My next step was to try a POST card but read somewhere that if pc boots then this will not show anything, pc is vista 32bit home premium, intel core2 quad, nvidea gforce 8400GS video card. Anybody any ideas, thanks. Rob

Try re seating the video card, also if you have on board graphics give that a try.

I've reseated the memory,video and usb cards, would the graphics be part of the video card?

On board graphics would be on the mother board, boards like that do not require a video card.  What make and model video board do you have?

The video card is nVIDIA GeForce 8400GS (256MB) and the motherboard is Foxconn G33M05 with Viiv.

According to the specs the board does have on board video, that is all well and good if the processor/cpu supports it.  The board and cpu work hand in hand, you need to check to see if the cpu does in fact support on board graphics.

 

Write up on board!

Was the same cable used when you tested it with the lap top?

Look at the back being as it has on board graphics and a graphics card there should be two VGA ports, one on the card and one on the header where all the jacks are.  Switch the wire to the other port, you may be in the wrong one the unactivated board port.  If that produces no result then I would be looking at damage to the board its self from transport.

Congratulations, I never used this other port, but all is working fine now, thank you for your time. Rob

Glad it turned out to be nothing, but now the mystery!  Which port are you in?  The card or the board!

The card! The one thing that has changed is that I am only able to boot up using a ps3 keyboard and pressing F1 but I'll look at that on Friday. Thanks again.
