Hi Imedia 2215 Packard Bell, Intel Celeron, Vista 32. CPU powers up and makes all the usual noises; keyboard lights all flash on briefly but then the usual Num Lock light does not light up. Monitor (AOC N20WB LCD)indicates 'no analogue signal' - so I guess the monitor is working? Any ideas - and if it is the graphics card -can anyone suggest a replacement? Many thanks.

It might be the graphics card kaput or it might just be a loose connection. Suggest you reseat everything inside and out (and clean any dust/fluff). Before you do that discharge any residual electric charges by unplugging at wall socket and hold in the power on/off button for 30 secs or so.

Does the motherboard have onboard graphics? You should see two VGA connectors at the back. You will have to open the case anyway and remove the GPU card. Once the card is removed then close the PC case up and connect monitor to onboard graphics. If it now displays OK then replace the GPU.

..and take rdave13's advice. I forgot it might be onboard graphics or if not then remove card and try it.

Thank you both for the suggestions. Apparently it is onboard graphics -so it looks like the motherboard I'm guessing?

Try connecting the PC to the TV if your are able to, do not right of the motherboard just yet it might well be your monitor.The cable might also have failed. Many a problem has been sorted by trying another cable.

If you want to buy a separate graphics card you will have to know the motherboard make & model before you shopping :)

You could maybe use a card from another pc to see if it works before you splash the cash.

It turns out that one of the two memory slots has a loose connection to the motherboard. So two IGB modules have been replaced by one 2GB module in the good slot. All working. AMny thanks to all who helped.
