i posted here because i think this may have something to do with something internal
Friend asked me to look at a system that was gummed up with malware, he brought me just the tower.
When i first tried to boot the system with my monitor mouse and keyboard, the monitor worked, so did the mouse, but the keyboard(PS2) wasn't recognized.

he brought me his USB keyboard and mouse , this time when i rebooted the monitor would come on. ( this is onboard VGA)
I took the HHD out of his system and installed it in mine, boots fine, i was able to clear the malware. No issues.
Put it back in his system...power up..no beeps everything seems to run fine, except no monitor.
So i put in and old 9800 pro AGP card and tried that.
Nothing.
Any ideas what could be happening?
The board is and ASUS P4R800-VM

first thing that comes to mind is bad motherboard. Have you tried running all his equipment but his mobo in another system or is that feasible?

haven't tried that, really not feasible, i don't want to waste to much time on this, i may just find a cheap board to switch out with and see what happens.
Just thought there may be something else i could do...a hard reset of some sort

Do you get no monitor activity at all times? Does the monitor work when booting into the BIOS?

First check I would do is on the power supply, especially the American/European electricity switch on the back. This is very most likely the issue if your computer is powering on, but not booting or running POST, as you said in the title.

Another quick solution you could give a go would be to reset the CMOS on the motherboard, unplug the power lead to the hard drives, then try to boot them system into the BIOS screen. Verify all cable connections, check that the monitor is turned on, etc, and if is continues to not function then you have confirmed that you are having a problem with the motherboard.

you could try that but in my experience, if the switch in the back of the PSU (If it has one not all do) is in the wrong spot the computer will not boot at all. I dont see how resetting the CMOS will fix it, but its easy and fairly simple to do and definetly could not hurt to try.

Just had a similar problem on a machine. The PS2 keyboard port was bad. Probably from being unplugged\plugged in with the machine on. It would not post with the USB keyboard plugged in. But with the USB keyboard unplugged, the machine would turn on, post and boot into Windows. The USB keyboard could then be plugged in and all worked normally.

Come to find out, the owner had had this problem almost since the first day. Some BIOS have settings to work around this. In my case I could not find any.
