My Specs are listed Below.

I was playing Fallout 4 one day on my gaming pc, paused game...went to bathroom..and wham...no source signal since then no matter what i've tried. I've been playing FO4 for months without any heating issues or crashes but im not ruling out that somehow i burned up my pc somehow. Upon pushing the power button everything looks ok other than no source signal. At first i thought it was the graphics card because..well it's usually the first thing to check out and upon inspection i saw the fans would start for 1.5 seconds and stop for 1.5 seconds repeatedly but am not sure if that's normal so i had it replaced and still no fix and new graphics card does the same so... All the pc fans work aswell the cpu cooler fan, i hear no beeps and no warning lights are activated upon pusing the power button. I hear no start up sounds but it's been months so i dont remember if it gets stuck at the log in screen before making sound ect.

I wonder if my gpu, cpu, or motherboard burned up. I did get two notices over the span of 8 months that fallout 4 was using alot of memory or something but never received a crash or a heating notice or a "random shutdown" to preserve the computer from overheating. im not a technician by any means other than i know how to put a computer together.

I've plugged my other very low end pc up to the monitor with the same cords and it worked so i doubt it's the monitor or any of the cords. fun fact my keybord NumLock CapsLock and ScrollLock lights do not operate on my gaming pc but will on the low end pc. My wireless mouse lights up on both pc's.

I've tried:

moving the ram around unplugging pc and holding power button for X seconds Replacing DVI cord switching Dvi cable between graphics cards dvi ports and mobo dvi port completely disasembling, cleaning, reassembling checking pin things on back of cpu resetting graphics card in other ports Replacing graphics card reapplying thermal paste loosening/tightening screws Taking out the battery, rubbing it, reinserting

I've heard about taking out some sort of "bios" object out of my mobo and moving it around but could never find it or find my mobo handbook.

It's been like 3 months....i've searched for everything and tried what i've found. I've reached my limit. Please help.

Have you tried removing the graphics card and plugging the DVI into the motherboard so that it uses the integrated graphics on your CPU? That would rule out any issue with GPU.

My instincts are leaning towards a motherboard issue, if you have access to a local pc repair shop then maybe see if you can borrow a motherboard and test it all with that. They may charge you but it will probably be cheaper than buying a new motherboard.

Usual starting point s to strip it out of the case and assemble mootheboard on a sheet of newspaer

Just Cpu and fan - one stick of ram and on board graphics and see if it will boot to BIOS. Swap ram sticks to eliminate RAM then slowly add parts.
