Just thought I'd bounce this off the other IT folks on here to see if I'm missing the obvious!

My home PC is playing up. It's an Asus CUSL2-C mobo (i815) with a Matrox G400 32MB DualHead AGP card etc etc.

For the past few days when I've switched it on at night, the PC will POST but the monitor doesn't come out of standby. If you leave it alone, you can see / hear the HD start to load up Win 2000.

Tonight it took about 40 resets and 4 power cycles for the monitor to display anything.

The last three times I've got it to display something, the first boot into Windows 2000 is useless as Windows thinks it has a bog-standard VGA in and runs at 640 x 480 x 16. One reboot later and I get my proper 1280 x 1024 settings back.

I've swapped in a spare ATi Xpert AGP Card and this gave a video output straight away. Put the G400 back in and no video.

I'm pretty sure it's the G400 this is on it's last legs but just wanted to check.

TIA.

I think by doing a swap out you have pretty much confirmed your own theories.

It sounds like a duff Matrox card to me.

Note - if card was totally dead you would get a POST beep code, which I presume you are not getting.

You have got the monitor connector in the right socket haven't you? - it has to be in the top socket on the dual head backplate. If not you will get exactly this symptom!!!

I do get a POST beep, the FDD seek and then Windows starts to load, I just don't see anything. Yup, monitor is on the right connector as when it works I don't have to change anything.

Just spoken to Matrox and a guy there suggested flashing the BIOS on the card. I hadn't thought of that, so will give it a punt tonight.

common problem with AGP cards, especially with AMD chips.

There have been numerous suggestions, some of which work for some people.

Mine was fixed by upping my voltage to the bus at bit, but you cant do this on all mobos

The card has fine since I brought it nearly two years. I used to have an Abit BH-6 BX chipset board and it worked fine in that.

It's been running fine for at least four months in the CUSL2-C with a Celeron CPU.
