I f I let my PC sit for a few hours I can get to the BIOS Setup screen/or windows. After about a minute if I am in windows the monitor loses the signal. If I am in the BIOS Setup the scree n freezes and nothing changes. After that if I resetart he pc (turning power supply off unplugging and waiting 1 minutes). I monitor gets signal for a shorter period of time then the same thing happens. Eventually the Monitor never gets signal. Once again if I wait for some time, usually an hour, the monitor will get a signal for a short and lost it. The first thing I did was get a new graphics card. It didn't fix the issue. I have disconnected/removed everything but the power supply and graphics card and the same issue. I have removed the memory and installed only one module and got the same issue. The same happened when I swapped the modules, so I don't think it is a bad RAM issue.
This is probably an over heating CPU(processor). Make sure the fan over the processor is working. If it is, check to see if the heat sink is fastened properly to the motherboard - if you can push on any of the corners and it moves in than there's an issue.
Also look for a thick layer of dust that might be blocking the air flow.

Make sure you have installed all the drivers installed, especially the chipset drivers.
Personally though if it isn't a Bios problem then I suspect that at least one of your capacitors on the motherboard is going out. It appears to have the old style capacitors installed which were less durable than most made for today's motherboards.
The fact that it freezes after a few hours really make me think capacitor problem or a memory leak.
If not, reset the mobo: either remove the mobo battery for a few minutes, or "short-out" the two reset pins next to the battery or next to the CMOS BIOS chip.
If you are not using the built-in video interface, then put two monitors on the system and adjust the way you want the monitors to behave.... or disable the built-in vga interface through the BIOS setup.
try to reset the BIOS to default either take the M/board battery out for at least 1 hour reinsert battery and try or On M/board will be writing with reset bios or similar usually a small 2 pin connector with a jumper on 1 pin connect jumper over both pins remove jumper refit over 1 pin and reboot If 3 pin setup remove jumper and fit over middle pin and the one it was not on replace back to how it was and boot computer
Hi 2gerr, when you tested the board, was the board outside of the you're case?
Here is one suggestion you can try. Start the PC & press the F5 key every two seconds untill Windows Advanced Options Menu
is displayed on you're screen. You can not use you're mouse here. Use the up & down arrow keys & slide to, Disable automatic restart on system failure. Than press enter. What this should do for you is stop windows from restarting & give you time to catch what is causing windows to restart. If you receive a blue screen with an error message write it down. Press the pause key on the keyboard so you'll have time to write down the error message. It would not hurt to enter you're bios and turn off hault on all errors listed in the main menu of the bios.
Another could be the back side of the board could be touching the case. You can add a piece of a paper bag under the board.
Stopping a possible short. Lastly, enter you're bios & go the hardware monitor. Open hardware monitor & leave it there. Shut off you're monitor & walk away for about 10 minutes or so coming back from time to time & check the temp of you're CPU & mother board temp. Staying in the bios, let me know if the PC restarts.
When you can get it to start, go directly into the bios. Once there find hardware monitor. (if your bios supports that). If so, here you can monitor cpu & motherboard tempture. Just let it sit. If its a heat issue you will be able to see it in the bios. Also lets see if the pc restarts by itself. If no restart takes place I would guess this is a software issue. Possible virus/worm. Pull the system memory & reseat. Reinstall windows.
