I have an AOpen vKM400Am-S Motherboard, when i turn it on a red light and cpu fan turns on but no video to my monitor,i checked if my video card works on a difrent pc and it did, my pc wont turn on

this caused by RAM error, open your computer, disconnect ram, turn on your computer?is computer beeping, 1 long and 2 short beep??if yes the problem is come from your ram, clean your ram connection then connect ram to mother board, turn on your computer, is the video come to screen??if no, try to connect another ram to your computer, for sure use new ram
i hope this helpful

Support prosesser

Fixya do an online manual for this motherboard here

The product specs can be found here

According to this page your Motherboard accepts a Pentium 4 processor on a socket 478 and a FSB of 400MHz so I would think it should support up to a 3.2GHz processor.

Hope this helps

Driver sound

Your mobo doesn't have onboard audio. So you will need to go to an eletronic or computer store and buy one. They range from 10$-200$ depending on the quality of sound you want and what you intend to do with it.
