Have you tried a different power supply with this system?

No i don’t have another psu. Could it be dead?

Anything's possible. What I would do is bench test the power supply disconnect it from everything and jump start it using a jumper wire between the green wire and a black one in the atx connector. Then use a multi meter and check to make sure that it's putting out proper voltages.

Does sound more like a cap has (silently) failed but in the meantime-

-what ram were you using before the upgrade
-what spec / part nos are all the ram sticks
-although it shouldn't prevent booting, isn't there an issue of using all 4 memory slots downclocking to 100MHz instead of 133MHz
-if the battery came with the board, try a new one
-seen posts elsewhere of this board not liking TI4xxx series cards; try a different video card

I tested with just the matrox mellenium and 128mb of ram. And it still didn’t power up. They’re 100 to 133mhz.

I’ve tested the psu and the fan spins.

As always:

Remove all components except the CPU (yes, no RAM) and power on. Does it beep? If not, you have probably caused some serious damage. If it beeps, start adding a single RAM module. It should now give a different beep. Then add a VGA card and see if it posts.

Weird it’s now working after putting the psu back in.

Sometimes i get video showing up and sometimes i don’t. But my OSSC always detects a signal.

Will test on another tv. Don’t Have CRT’s unfortunately.

Given the Mainboard in the OP has no native support for Tualatin CPUs could it be that an adaptor is causing issues?
Have you tried Coppermine CPUs?

I baught CPU’s from a South Korean seller which has the adaptor preinstalled never had any issues with it. And i managed to get my PC working with a monitor i found outside.

Happy to hear that. 😀 Maybe it was just a bad connection - I've had a PSU with one contact loose in the ATX connector. It would often push out when installing it to a board giving me similar issues.

Yes glad it was the PSU and not the motherboard. I managed to get Windows 98SE installed but can’t seem to get XP installed. I keep getting NTLDR is missing error. Tried to install it multiple times with different ide cables and through different ports. But same issue.
