Hi, I have an old P133 w/32MB ram that doesnt seem to want to reboot anymore. If I use ctrl+alt+del or push the reset button on the box, the monitor shuts off, and the power light on the box just flashes. I have to actually turn the power off then on to get it to turn back on. I only use it as my router so it only boots from a floppy, but is very annoying. Could the be a BIOS problem? Or a video card problem? Any help is appreciated! Thanks

You may need to clear cmos on it. Sounds like something in motherboard PWR management is actually putting the system in standby instead of reset indicated by the power LED flash.

thanks for the input. I cleared out my cmos but the problem persists. Any other ideas? Thanks

Do you know what motherboard is in it? A little more info can go a long way in curing boot and reset troubles.

not really sure what motherboard it is...I am assuming it is just an Intel board. There really isnt any writing on the board, the chips are all intel and dated 94' the board is dated 95'. It is an old Gateway 2000 pc. None of my paper work mentions the type of board either. Funny that my paperwork says it is ATX however it is not because it has the old style power connectors on the board and the power switch goes directly to the power supply and not the board like on ATX boards. It also has dipswiches on the board that are used to clear cmos password, cmos settings and proccessor speed. No jumpers. Any chance its a bad video card? Thanks again.

Gateway 2000 helps, There should be an actual model number somewhere on the case. I may know what is going on but I need to have exact info for the Gateway in order to look through my Archives.

I would suspect the video card in this case or a failing memory chip, the video card being more the culprit. If you have an old ISA video card about you could swap it temporarily to check for PCI related problems as well. The video card wouldn't happen to be an MGA Matrox?

Also check your power saving features in the bios and disable everything.

yes, it is a MGA Matrox pci know your stuff! Is this a common trait of those cards or something?
