I Have a P5K-VM, It posts and begins booting, then it shuts down

Two beeps is usually the video card.
Do you have a spare video card to change out?
This is why people keep obsolete PCI video cards for just such tests.

hi yrmahindra:I make This video for you wish i help

Perhaps. It is a very old MB. Are you sure its the computer freezing and not just the video? After a cold boot, try forcing it to sleep with keyboard. If it does sleep wake it up. Does video work again?

check the cpu voltage to the board jim

if its a case of power look at the psu. try another to see if this remedies the situation

Please don't forget to rate this solution.

The onboard battery that keeps the CMOS or BIOS settings is bad. It's a large flat battery that looks a lot like a watch battery just larger. Carefully remove it and get a replacement. Numbers for the replacement should be on top of the old battery.

this is your bios battery put new one in and it should work

Hi jderek4, try this. locate the toggle switch on the back of the power supply. Just find it do not flip it.
Plug the PSU's power cord into the PC. Just as you got a good connection & the PC begains to power up move the toggle switch to it's other position. The PC should power off that very second.
If the PC does not shut off than the PSU is bad. If it did shut down wait a few seconds. Press the cases power on button. The PC should start to boot up. Let it finish loading. Click the start button & choose to shut down windows. The PC should shut off.
Yes? If not than your back to (bad power supply). Swap it out.
