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

Hello
You've said that there is no start up with your hdd even you hdd is defective your CPU will turn on and have display in your monitor try to turn your computer on then push the button delete or a f1 button it depends on your bios that you have using. If your PC tun and display the bios it means your motherboard is good. Then in the bios set up put it in the main section you will see if your HDD is detected by your PC if not then you HDD is defective o have a lose contact on its connectors.
If you don't have a display try to check if your CPU have a video card. Turn off your PC then pull out VGA connector that are connected to your computer then pull out the Video card in your motherboard which connected to a PCI slot then tun on your pc using the on board VGA connector which is located at the back of your CPU which is beside the parallel port and on the lower of the mouse and key board connectors. If the problem is still there try to clean your Memory cards which is located inside your CPU unit and located at the left side your motherboard and beside your processor. Clean it with a pencil eraser. Then put it again in your motherboard. If problem is still there. Try to check your power supply may it dropping voltage where the did not full fill the requirements of your computer. Hope this will help.

could be the whole pc is fried :(

check your power supply with tester first make sure that all power plugs are in all pluge on board some take a 4pin plug by the cpu socket as well looks

It's the round shiny chrome disc on the motherboard. Remember if you change it you will need to reset the cmos in the bios.You can contact me and I will walk you through that part.

Probably your mobo does not support 1 GB RAM in one DIMM slot.. Check Motherboard Manual.

hey, here is the latest bios witch is required for your new sempron!

CHANGE THE POWER SUPPLAY.. BUT FIRTH..

1-UNPLUG HD AND TEST WITH FLOPPY OR CD BOOT DISK

2-UNPLUG YOUR MEDIA ROOM LIKE CD OR DVD AND TEST ONLY WITH FLOPPY BOOT DISK

3-UNPLUG VIDEO CARD AND ALL CARD ON YOUR MOTHERBOARD.. TEST ONLY WITH THE FLOPPY DISK AND ONBOARD VGA.. OR GOOD TESTED VGA CARD.
