Question about EliteGroup L7VMM2 Motherboard
My friend has an emachines T2200 which uses the L7VMM2 version 1.0 motherboard. Two weeks after adding memory, his USB keyboard stopped working. It won't work on my computer either.
The next night, his PS/2 mouse stopped working. It doesn't work on other computers. My mouse worked fine on his computer, until he rebooted. Then the video signal would not come through to a normally working monitor. After 3 reboots, the video came back. After another reboot, no video again. There is also no BIOS beep.
The next night, we noticed the power LED on his case would not turn off, unless you unplugged his power supply. In addition, my keyboard will no longer be detected by his computer.
His harddrive, CD, DVD & Floppy drives are all able to be seen on other computers. We can't test his power supply on my computer, as my MB uses 24 pin connectors and his supply is only 20. However, I tested my 20+4 on his board and got the same error. As a matter of fact, the PSU's fan ceased working after the test.
It sounds like the motherboard to me. Does anyone agree? Also, what might have caused this?
It seams that the motherboard has some power problems. Check on the motherboard for burned or blackened components, or for capacitors that are looking like they are going to blow (inflated on the top), u can do the same to the power supply.
If so change it !
Also maybe the power of the house has problems that the computers power supply cant handle (that can ruin the motherboard or other components )
U can also try to isolate the motherboard from the case (there might be a short between the motherboard and the power supply through the case metal ... )

Usually you need to disable the on-board video/activate the AGP slot in the BIOS before adding the video card. (Check your manual for entering the BIOS - often hit F1 or F2 (or enter when prompted) as you start the computer before the OS starts loading.)
I have no idea how you see the BIOS information without a working video to start.
