This is usually due to a memory failure. Take out all the RAM. Check the contacts to make sure they are clean, and use compressed air to clean any dirt that might have built up in the RAM slots on the motherboard. Then plug in one module only and try restarting. This can help you get a handle on which piece of RAM is acting up. If you have only one module, or the problem continues with any module you plug in, see if you can borrow a known good module to try. (I've been thrown by multiple bad RAM modules in the past. Went nuts trying other things until I stuck in a different piece of memory - found all 3 of the customer's modules were bad. I've been careful to check that first ever since.)

If the problem continues, you'll need to replace the motherboard.

I'm using mercury mainboard kvm266pm-u with sempron cpu but it freezes a few minutes after i start up the PC, even in bios set up. the link for bios update to the main site is not working. how do i solve...

Is your CPU and HSF fitted correctly?
Usually if you get freezes and shutdowns it is due to overheating.
You may also have a virus/malware infection.
Boot into safe mode with networking (F8)
turn off system restore
Run a virus scan
Download Malwarebytes and give it a full scan.
