I was playing LoL today and suddenly both of my monitors lost connection. My computer kept running, the graphics card, case and cpu fans were all still running, but there was no connection to both of my monitors. So I tried to reset my computer by holding down the power button for 10seconds, I held it for 20 seconds and more and nothing happened. So I unplugged my computer, hit the power button on the motherboard to discharge it and then reset the motherboard and checked the connections and reseated the GPU. Now when I turn it on all it does is power up the lights and fans but there is no connection to the monitors, I also have to unplug it every time to power it off. Any suggestions before I reset everything and have to test each piece of my computer?

I don't think it's the cables because Both of my monitors lost connection.

I haven't removed the CMOS battery yet, but I have a reset button on my motherboard that didn't work, but I'll try to manually remove the battery, sadly I only have outputs directly from my GPU.

Its not likely to be your monitors problem. If the PC isn't starting, and POST, then you have more fundamental issue with MB/CPU/RAM/GFX. GFX is generally the last on the list.

The suggestions about removing the CMOS battery is a start, After than, unplug things you don't need to do a POST, and try and get that working. Then add back in items slowly. If you have onboard GFX, use that to get the POST working.
