I leave my computer on all the time. Found it dead one day. Changed the PSU to a new one (test shows PSU is working). Push power switch on with no response. Fan turns for about a second then stops the only other thing that works is the power switch led is on. How do I check if it is the MOBO (Elitegroup P4M800PRO-M) or something else? Thanks

Thanks I will try that.
Angel, the beep code for a dead CPU is ... silence.
I unhooked everything (graphics card, memory chips, hard drive, cdrom, zip drives) except for the mobo. I press the power button, the case fan and cpu fan spins for a second only, no beep and no computer. Is it the mobo or the CPU that is dead?
Also double check and make sure that your cpu cooler is seated properly. I once had the retaining clip break, a few years ago, and that would turn on for a few seconds and then power off. I had a neighbor downstair who would get mad and slam his door sending a concusion through my floor. broke my retaining rings twice before we finally had a talk. Anyways, good luck
changed the mobo today and it works. thanks to all
