Does anybody know a fair bit about computers? Well, mines kind of broke. I have a Packard Bell desktop PC which up until a few days ago worked fine.

So here's my predicament, when I turn the PC on I get all the power lights turning on but the screen doesn't display anything. I've tested it on a different monitor so it's not that. Also tested the VGA cable in another PC so it ain't that either. I've tried opening up the PC and cleaning it out and disassembling components and putting them back together but I still have the problem.

Can anyone diagnose my problem? Any help would be great!

I had this trouble with a laptop, the video processor packed up and I had to go back to my old laptop, as a PC is less compact it should be fixable as once one thing goes on a laptop motherboard it's usually goodbye but a PC can be opened up and taken apart easily(if you know what you're doing...)

My guess would be its either my graphics card, or the motherboard but the LED light comes on inside the computer on the motherboard. I've done a bit of research and it seems like a few people have had this problem on Packard Bell PC's. I'm running out of ideas

Bet its the mother board I bought a new HP tower computer a few weeks ago got it up and running and three days later the integrated graphics card went pete tong and took out the mother board.

This one seems to be ok ................

What model Packard Bell is it, can find out if it's integrated or separate graphics card and help you (or not) from there.

How old is the PC?

have you got a laptop you can connect to the monitor (elimination process) could be the monitor but my guess is graphics/motherboard

Sounds like on board graphics gone kaboom...there may be expansion slots to stick another one in but PB are not usually very expandable...also could be issues disabling on board graphics if ya cant get it on to view bios.

I had similar prob couple weeks ago. Turned out to be the power supply unit inside tower. £12new from system works in Anlaby. Ive now got a spare 1 if you want to try it before paying out.

graphics card failure is usually indicated by 9 bleeps on start up
