Hi All. I've lost my signal output to my monitor after moving my computer. Not a complete novice I've had the back off and pushed and pulled the cards etc. My display adapter is integrated on the motherboard (not good I'm thinking) and I'm stuck. Any tips on how to diagnose or re-install drivers when you can't see what you are doing? Or, how can I tell if the adapters dead? (Please don't say no signal output) Cheers.

Does it display on your monitor "No Signal" or is the screen just blank? It could be the monitor has failed. Try another monitor.

:thumbsup: to BC Praetorian.

Check in the end of the monitor cable that there are no broken or bent pins (some pins are missing - that is normal).

Sadly not that simple, monitor working perfectly. Strange though, trying a second monitor (also working properly) it did not display the 'no signal or cable disconnected' warning it just stayed blank. Of course that could just be what it does.

Thanks for the reply - appreciated.

If nothing appears on the screen when you power on you can forget drivers since Windows is not even loaded at that time. If that is the only display adaptor the BIOS should be sending boot messages to it during the POST testing.

Does the PC appear to boot? - power led on, disk activity, keyboard leds blink? If so your onboard display may have died. Buy a plug in video card/AGP to replace it and carry on. If the PC does not do much other than spin the fans then you may have other problems. (e.g check your RAM has not come loose)

Try a BIOS reset - check your motherboard manual (or close inspection of the mobo near the CMOS battery) should (but not always) reveal a jumper which will clear the BIOS settings back to factory defaults. Exact method depends on the motherboard but usually you just have to move the jumper for about 30 seconds.
