Odd one this..... The Pc fires up, disks spin, power fan and cpu work, but the monitor displays nothing, not even bios screen. I have tried different monitors and vise cards but exactly the same occurs. There is only one ram chip installed (128mb)and I wondered could it be that taht is knackered and if I took it out, would you expect the pc to boot.?

If you took out the only RAM chip, the machine would not boot up. You'd simply get a series of beeps indicating the absence of RAM.

Your problem, however, points to either a bad video card or a bad motherboard. I'm not familiar with what a "vise" card is, but if that's British lingo for video card, I suppose you've already tried that. Nonetheless, a faulty video card or bad motherboard is what I would suspect.

Good luck,

Maxwell

No "Vise" card is not british slang for video card, it's my terribly typing>!!! Video card is what i was meant to say.!!.. I changed that and still no good, so i'm sure your right it must be the m/b

It is possible the video bus is in a "wait state". Thus, waiting for an ACK command. You may try to clear the CMOS and then reseat all components.

Is your monitor powered by the PC because if it is it could be the power cable or power unit which is faulty. I would also reseat the CPU because that sometimes causes this problem.

Can you swap in a different memory module, or CPU?
I would rule out that these 2 parts are not bad before changing out the motherboard.

Also, have you flashed the BIOS recently?
Try going through the procedure to reset the CMOS memory.

Have you tried to boot in safe mode? F8. Maybe the system won't support the resolution that the video card is set too. If you get to safe mode try changing to a lower resolution. Good luck

Other accesory cards may also cause this type of problem. Remove modem, lan and sound cards, if present, and see what happens. You can also try this with the drives but it's most likely the modem.

Sounds very much like ram is the blockage. Maybe that board only takes 64s, or a specific type of memory than you are using now. Maybe the motherboard has a jumper to enable or configure VGA/mono settings. Especially if the parts are used and then sat around for awhile, look onto each card and the motherboard board to find the chips that are socketed rather than soldered on, and press gently down on these to reseat them in their sockets. Chip creap happens. . cheers.

It sounds like CPU & Bios is getting a post(Power On Systems Test)done, but how is your computer's case MB chassis? You know what computer cases are made of, "Beer can metal", and if your case isn't bent niceley your card might not be setting correctly. So, after a post is successful its something else that you've added to the MB that is messing things up other than the MB. And remember to check your Bios batteries every 3-5 years for the source of error.

I had the same problem... It was simply that the memory wasnt seated all the way down. Insure that everything is seated properly.
