    All the capacitor have flat and clear tops. One thing I should have mention is before replacing the power supply the previous power supply toasted. It smell really bad. So that's the reason I had to replace with the new one.

Sounds like a thermal issue. New power supply might be overheating the cpu causing the thermal sensor in the cpu to automatically shut down so the cpu doesn't fry. You could try adding a case fan or two plus upgrading the spu heatsink/fan. Hope this helps.

It sounds like a power supply problem not the mother board, you have some bad electrolytic caps in the power supply that need to be change, or just replace the power supply.

I have a computer with an Intel D845GEBu2/D845PESV mother board. One day works great, next day no longer powers up. I changed out the PS, all I get is a small green light on the mo bd that lights up...


If all you get is a green light, and no fans, hard drive spin up, nothing on the monitor, well than, it could be that the power supply is the wrong one for your computer. Either that or the motherboard is shot.
double check on the power supply, that is probably the problem.

Computer turns itself off


try installing a chassis fan to reduce heat inside your case, as the other guy said, dust is a big possibility, the problem does not appear to be CPU but I would check to see that the spu fan is running normally.

Another thing could be that it is time for a more potential power supply.

My pc is not turning on Asus p5vd2-mx se


what kind of computer is it? how old is it? have you added, removed or changed hardware recently? have there been any power spikes, outages or surges lately while the computer was running? lastly are the voltage settings 120V/240V on the power supply set correctly? it sounds like the power supply is dead from what i've read but i can't be sure because there are many reasons this could be happening, i.e. the processor gets too hot while the system is trying to start and the computer shuts down to prevent damage to it, also have you tried plugin the system into another wall outlet or socket on your power strip? if no hardware has been add, removed or changed. you can start with a power supply but if after that it still won't power up there's a deeper cause to look for!

hope this helps

Remove you CPU Heatsink and fan, look around the socket for possible capacitor damage. look at the small brown ones if the top shinny surface is poped up like in this illustration. If so then replace you motherboard
