I have an ASRock Z75 Pro3 motherboard in my tower PC running Win7. I started having a problem of no display on my monitor when doing a power on boot. No ASRock splash screen. No display of any kind.
After much troubleshooting, I finally discovered that the problem only happens if I shutdown Windows and then try to reboot within 10 minutes (approximate time). If I do a restart, it boots back into Win7 fine. If I wait about 10 minutes and then do a power on boot, it boots into Win7 fine.
What is happening is that the ASRock motherboard is hanging in POST after a shutdown. When the PC is working, it first lights the numeric lock LED on the keyboard in about 2 seconds and then the ASRock splash screen displays immediately thereafter. When the problem happens, the LED on the keyboard doesn't light up and the motherboard hangs in POST with no display on the monitor.
I disconnected EVERY cable except the PS2 to my keyboard, USB to my Logitech wireless receiver for my mouse, and the ethernet cable. I removed all cards plugged into mobo slots. The monitor is connected via VGA to the motherboard. I disconnected my SATA data hard drive and my optical drive. I moved my OS SSD SATA connector to a different header on the mobo. The no boot after a shutdown still happens.
Apparently there is something on the ASRock motherboard that needs to bleed off voltage before it will boot after a shutdown. If power never goes off, like for a restart, the mobo boots up into Win7 fine.
I did some Googling and found that other models of ASRock motherboard can have the same problem.
ASRock tech support authorized a RMA but will not tell me what on the motherboard is causing the problem. The RMA department says that I have to pay for return shipping even though I pointed out to them that the problem is a known ASRock problem and is happening on other versions of their motherboard. I asked to be connected to a higher level to request that ASRock pay for return shipping but they won't answer my email.
I asked ASRock if anything has been done to correct the problem on the Z75 Pro3 mobo since if I pay for return shipping and just get a same type of motherboard, what's to prevent the problem from happening again? They won't answer my email.
1. Anyone else with a ASRock motherboard having a no display on boot problem?
2. What happens in a power on POST that doesn't happen during a Win7 restart?
Thanks,
