Keyboards and Monitors Don't work with my computer

[PcSeric]

The other day I came home and turned my computer on, it booted up, but the Monitor stays on no signal, AND no keyboards work (light up) with my computer. The mouse works so it is not the USB power. I've tried multiple keyboards and monitors and DVI cords. A possible cause of the problem might be due to the fact that I have been turn my computer off through the extension cord button instead of the computer shut down button. I've tried the 30 second button hold and moving my ram to a different slot. Checked all the cords. Any help is appreciated.

Are you saying you dont do a windows shutdown? This may just be a bios problem. Try resetting your bios and if you dont know how just remove the motherboard battery for 5 minutes.

@elbert how do I reset my bios? And yes I haven't been doing a pc shutdown

Does your monitor show the bios on boot? If so you may just have a very corrupt OS install. You really need to do windows shutdown. Just unpluging can corrupt every file loaded into memory.

To do a bios reset find the battery on your motherboard and remove it for 5 minutes. here is an image but the battery can be anywhere on the motherboard but they are always round. Just pull it out for 5 minutes, put back the same way, plug up your PC, and start your PC.

@elbert no it doesn't show the bios on boot. Also the computer is 2 years old and the night before I realized it was broken I had turned it off by the power cord switch

If removing the battery reset doesn't help you should try removing one stick of RAM and test. Then test the other RAM stick. Also try reseating your video card by pulling out of the slot and putting it back in.

@elbert I've tried all of those things. No luck

Last thing I would try is unbolting the motherboard and set it on the motherboard box with everything still attached. This will test if the motherboard is grounding on the case. reset the bios so we get a good test. The try the RAM remove again while on the box. Unplug all drivers and try to just get into bios. If this doesn't work either all your RAM, the motherboard, or CPU has died. My guess is the motherboard.
