Bad PSU or mobo?

Hey all, I'm having some problems with my system ever since I tried to plug in my floppy drive today. When i did, the system would not boot up at all until I reseated most of the components.

Then, it would do a hard lock sometimes before loading the OS, sometimes while loading, and sometimes when the OS loaded.

When the 1.3 is clocked at 1.3, it says theres an AGP problem and my GF2 Pro wouldn't work at all unless I clocked it down to 1.15, then it would work fine.

It wouldn't boot into windows for a while until i removed the optical drives and booted, then reattached them and restarted.

The big problem is the computer freezing between 15 and 2 min. of bootup. The computer would also not stabalize at all until I did some combinations, right now it's pretty stable but I had to take out the sound card.

I'm running a 1.3GHz athlon on a KT133A board on a 300W CompUSA (generic) power supply. I've had this PSU for a while and it gets pretty hot (almost as hot as the processor) and maybe it's at the end of it's life. Do you guys think it's the motherboard (this happened with another motherboard I had before) or the PSU?

Are you using same PSU now which you used on the old motherboard which had the problem? Did you get a replacement motherboard and using the replacement with your PSU solve your problem?

I think you are damn unlucky to get two mobos with exactly the same problem (then again, it is possible).

Do you have a spare PSU lying around which you can test your new board with?

Also, it wouldnt harm to check your RAM. Do you have more than one stick of RAM? If so, have you tried removing one of the sticks and seeing if the problem still occurs.
 
From the symptoms you posted it's most likely a PSU problem. Can you post some voltage readings taken from the bios?
 
12V: 12.25V
5V : 4.68V
3.3V: 3.38

I used the same PSU on this mobo as I did on the other one. The other one had DDR so it wasn't a RAM issue
