I'm stumped on this one. My friend and I built a PC awhile ago, and it worked upon building it. Then a few weeks later, it stopped working.
The PC will turn on. All lights and fans are working. However, there is no video output, and no usb power.
I tried the video card in a separate PC, and it works fine.
I removed the RAM and inserted known working RAM, and nothing changed.
I tried putting the video card in a new slot, and nothing changed.
I removed the battery for 2 minutes, and nothing changed.
Neither the HDMI nor the VGA component of the graphics card work in the broken PC.
So the video card, RAM, battery, and power supply all seem to be working fine. Yet no output shows on the screen, and the keyboard / mouse do not get power in any of the USB slots.
I'm really stumped. My only other thought is that the CPU or the Mobo are broken, but how can that be if everything is getting power?
Any help is greatly appreciated!!
