Hello everyone.  I recently had a failed Antec power supply.  It was under warranty so I had it replaced.  My system worked fine for a few weeks, but at this point the screen is completely blank.  No cursor, video screen, or anything.  I have tested the system with two different monitors and cables, so I have ruled those out as the problem.  When I turn the system on, the fans spin and I hear some general clicking and movement from other components that I can't pinpoint.  The internal speaker does not give any "beeps" to signify the computer is booting.

 

I am assuming that my problem is either a fried motherboard or CPU, but wanted to post this on here in case it's something obvious that I'm overlooking.  Is there a way I can identify the problem before purchasing components?  I do not have any additional motherboards or CPUs around the house.

 

Thanks!

Pull all the RAM out, then power it on and see if the motherboard complains. A healthy motherboard should beep a continuous pattern if the RAM is missing or bad. If you don't get any beeps with a bare board, (CPU, PSU and power switch ONLY, no drives or PCI(e) cards) then you can try resetting the CMOS, if that doesn't change the situation, I'd call it dead. The only way I know to rule out which is bad, the CPU or the motherboard, is by replacing parts.

Thanks, Jonathan.  No beeps with RAM and harddrives removed.  I have the battery pulled to reset CMOS now.  As a side note, I realized one of my other computers was also an AMD, so I switched out the CPU's.  Both seem to be working, so it looks like it's a problem with the motherboard.  If the CMOS reset doesn't work, I'll check the other forum for recommendation for AM2 motherboard.
