This sounds silly but I have one of those extension cord power blocks, with 6 plug sockets. And each socket has its own individual power switch. Anyway, last night, the cat stood on an exposed switch - which just happened to be the one powering my computer and monitor! This isn't the first time it's happened, so I switched back on expecting all to be fine. But it wasn't. All the text on the screen during POST had a fuzzyness around them, and moving dots. I was fuming. I haven't had this monitor long and I thought it was broken and would need replacing again. It wasn't just during POST, so I switched off and then started up again. This time, nothing happened apart from my monitor giving a message saying something like "Invalid frequency output" (not "No Signal") and so I came to the conclusion that the graphics card was at fault. Thing is, the POST gave it's usual beep and the disks started booting (could hear it) As it was late, I decided to switch off and intended to look at it today, but I switched on this morning and it seems to be working ok :s so I'm a bit confused, not to mention concerned - even though the system appears to be working ok. Do you reckon the problem last night was a one off or is it likely I have a failing component? Thanks

It's very hard to say but it is not unknown for transient problems to arise if the power is jerked. I'd guess you will be OK as long as you tether that cat (or protect the switches). DerekW

Open your case, remove the graphic card, put it back in and start your PC. This usually happens if the VGA card is not touching all the contacts properly. 386 WITH Math co-processor eat your heart out! 25 Mega Hertz 2 Mega Bytes of Random Access Memory 70 Mega Bytes of Hard Drive Diamond ISA Video Card with 512 Kilobytes of Memory 2 x Caddy
