My CDRW light, power and 'I am thinking' lights are flashing at mega speed. Blank monitor. no noises.

Have pulled computer apart, dusted with fine toothbrush and hoovered!

Put back together for same lights.

Took CDRW drive out, made DVD drive master. Still same result.

Tried putting CDRW back in as slave, still lights flashing

Any suggestions?

Make sure NOTHING is connected in USB ports and retry.

Unplug DVD CD power and data cables and retry.

Do fans run?

Fans running since I hoovered most of britains dust out of them!!

Desktop. Medion is make. Had it 5 years. Hard drive c, backup d, recover e. Cannot for the life of me remeber anything else about it and cant find paperwork for it. Dont suppose that helps much?

I assume totaly blank screen?

Fans running and lights flashing is a good sign that PSU is OK.

Not sur what you mean by the "I'm thinlking light" (HDD light?) if so then its trying to read the hard drive.
You probably have a corrupt XP system or faulty graphics card or monitor.

Check the monitor is switched on, check the leads to the monitor and rear of PC. try another monitor if you have one.

Husband just pulled apart, found a fan didn't know was there. Hoovered but still just lights.

Monitor blank screen when attached. No signal when not. So assume that means is ok.

Graphics card, haven't had proper sound on system for months is that part of graphics card?

Is it easy to just replace it? Unscrew pull out and replace?

Sorry to be a pain!

Don't get too close to electronics with a hoover, the static that builds up on the plastic nozzle can damage sensitive components.
Your sound may be provided by another card or is part of the motherboard, nothing to do with graphics card.

Graphics card is easily replaced just as you described. There may be a tab at the back where it plugs into the socket that needs releasing to free it.
Make sure any replacement card has the right connector. AGP is most likely on a machine 5 years old but it could be PCI.

AGP will be a brown socket; click here
PCI a white socket, also shown in the screenshot on the above page.
