Mpc 2000 not booting and screen flashing

I'm hoping that someone electronically savvy can help me. I was modding my mpc 2000 to include an internal scsi port and all seemed well continuity wise. After I put the motherboard back into the case I connected the psu and the screen to the motherboard to see if it would boot.

When I power on the mpc the screen lights up for .5 second and then shuts off . This happens repeatedly until i turn off the mpc. The psu seems to be turning itself off and restarting which is why the screen doesn't stay on.

I don't know if its my mpc motherboard or a psu issue. I've tested the psu with a multimeter and the values that I am getting are not 12volts or 5volts which I should be getting. The values that I get are just under somewhere around 11.95v and 4.5v

When I measure where the psu connects to the motherboard I get a fluctuating power spikes and drops that coincidence with the ticking sound of the psu and the screen flashing.

Has anyone had this issue before? If so does it sound like a psu issue? Thanks for any help.

It may be the power switch that's causing it.

Thanks,
Do you think it's something that is loose that can be resoldered ?

I'm not sure if that's the case. It's gotta be a failed component. I've had something similar happen with one of these switches. But I had a spare to swap it out.

Thanks for the help bro. As it turns out my motherboard was dead . I was very anxious to do the mod and I took the board in my car to work with me and it must have gotten zapped somehow. It was working fine before I pulled it out of the case. After I purchased a new motherboard it booted up instantly and detected the raizinmonster.

That sucks that you had to replace a motherboard. Hope you didn't have to spend much on a replacement. If you're still planning on modding the new board, make sure to store it in an anti-static bag like the one's that computer motherboards are sold with. When you're done with the mod, post some pics here.

Mod complete, pics coming soon!
