My home built desktop PC won’t start up. I can’t get it to enter BIOS or post. The system is about 2 yrs. Old. For the past month or two it would sporadically lose time / date settings, so I thought it might be related to a dead CMOS battery. Changed the battery and followed steps for clearing CMOS, still nothing. Here’s what I have:
Asus M2A- VM Mobo
AMD Athlon 64 X2 5000+ 2.6 GHZ CPU (black ed.), never overclocked
2 x 2GB Crucial PC 6400 DDR2 RAM
Antec Case w/ Antec Earthwatts (80 Plus) EA-500, 500 Watt PSU
eVGA geForce 8600 Nvidia video card
The mobo displays a green LED when connected to the PSU. When the power button is turned on no other lights or beeps come from the mobo. Case fans, CPU fan, Hard drive, and DVD drive all spin up. Previously I would get a beep from the system speaker as BIOS loaded.
Tried to power up w/ drives disconnected, removed RAM, and tried w/ each stick of RAM individually, removed video card, still nothing from the mobo (sound or video) when power is turned on. Called ASUS tech support, guy I talked w/ there thought it might be the mobo, waiting to hear back from them for an RMA as my mobo is still under warranty.
I ordered an identical M2A-VM via eBay (arrived in new OEM packaging) thinking it would solve my problem. Connected the board w/ same results – nothing on power up. I did clear CMOS and install a fresh battery before powering up the new mobo.
Any thoughts on if I may have a bad PSU or CPU? Anything else that would worth looking into that could keep 2 different mobos from posting and entering BIOS?
I may take it to a shop at this point for more thorough diagnostics. I’ve got an OEM version of Windows XP Media Center and don’t want to lose the license just yet. My wife will complain about having to use a different UI w/ Win 7, not ready to go there just yet.
