Monitor turns off during XP initialization!

  steved 15:18 31 Oct 2003

Here’s a strange one - I’m running XP on an Athlon XP2000 with 256mb RAM, and have just changed the PSU and case. I turn the PC on and it starts to boot as normal then, halfway through the ‘initializing XP’ sequence the screen goes blank and, after a couple of seconds, the monitor turns off. The PC’s still running and the HDD light is still on so presumably it’s still initializing.. Turning the monitor back on makes no difference as there’s no signal going to it, I just get the same monitor test message that I get if I turn the monitor on without the PC. If I press reset the same thing happens.

I then give up and turn the PC off... a couple of hours later I find that it’s turned itself back on again all by itself! (I suppose it is Halloween...)

Could be a overheating problem or you may have unseated one or more of your components, eg graphics card or memory. Suggest you remove all cards and reseat them as a starting point.

Thanks Sil_ver - it doesn't seem to be overheating (temps in BIOS are fine) - and it doesn't do it in safe mode, so I guess the cards are ok. Any other ideas gratefully received!!

This is a graphics problem, check card, cable and look for bent pins, reseat the card and make sure it is pushed full in. As the card worked out when you have put it back together

Is it possible that the new PSU is playing up? could try refitting the old one. Don't run XP so don't know if you can run msconfig to shut down all startup progs then reinstate them one at a time until the problem recurs.

Yes you can run Msconfig

I had this problem with XP, turned out to be a power supply problem. Got a new 400watt one since then the problem has dissappeared.

As a check next time you try starting the comp, watch the hard drive light to see if it continues to seek flash when the monitor turns of

Perhaps you've somehow set your refresh rates to be higher than your monitor is capable of.

Press the F8/F10 (which is it??) button when your computer starts up.

Then select the one that uses the lowest res and stuff.

Sorry I can't be more specific with names!!

As vinnielo start in safe mode right click desktop\Properties\Advanced\Adapter\Refresh rate
