Here's my problem my desktopwill no longer power up. Last time it did i was able to log in then it shutdown, no warning at all. I recently replaced the power source from 350w to 380w, same brand. I've checked the motherboard and power source for damage, there is none. RAM is relatively new 4 m/o. Please help me find a solution. I built this machine myself, being ignorant as I am. It has lasted me five good years with only 2 other required replacements: motherboard 2 yrs ago; power source 1 mo ago. I appreciate any help which may be given.
If we can get some more specific information, it'll be eaiser to help

.
First, define "won't power up". Does it not power on at all or does it start up for a short period and hang? Does it POST?
The first thing I usually recommend is switching out ram, if you have some lying around.

Actually, reseating all of your cables would be a good place to start. In replacing the power supply, you would have had to disconnect the power switch. That would be a good place to start.
