Graphics card problem; PC constantly shutting down

Hi guys, Ive been having problems with my graphics card, and before I send my PC off for repair, was wondering if someone here could help

Background

A couple weeks ago my friend asked to borrow my graphics card to use in his PC (his PC wasnt working and he wanted to use my graphics card to see if it was that causing his issue...). Anyway, he took my graphics card out of my desktop, put it in his, started up his PC and then shut down and put it back into mine. Whole thing took about 10 minutes, no bother. Ever since then, my PC has worked right though...

Problem

When I start up my PC it runs fine and will run indefinitely on MS Office programs like excel etc., however if I watch a movie or play a game it will work absolutely fine for about 7-12 minutes, then the PC just goes into power saving mode and restarts itself. Once it restarts then, the monitor remains black, like its getting no feed from the desktop. At this point, if I unplug the graphics card and plug the monitor into the graphics card built into the mother board, the PC runs fine again (albeit poorer graphics....). Another thing to mention is, when I start the computer first, if its plugged into the motherboard the monitor will remain black and say its getting no feed, it has to be plugged into the graphics card first (and inevitably it goes to power saving mode and restarts)

Ive tried disabling hibernation, checking the power saving settings and disabling everything there, but nothing works. Any ideas what this may be? If the graphics card is wrecked then why does it always work fine for 7-12 minutes? I thought it may be the PSU (since the PC always says its entering power saving mode), however the issue has to be being caused by the graphics card. Could it be some simple settings issue (like, when the card was removed from the desktop it set something off in the PC that meant it would always try to default to the mother board graphics card)?

Any help would be greatly appreciated.

Thanks
L

This sounds like the graphic card is over heating, therefore everything shuts down to protect it. 

 

Check if there are any dirt on its heatsink and fan if there is any, clean it.

 

Also check any other fans/heatsinks and clean them.

 

Please, also post the specs of your system.

 

EDIT : Also check if the heatsink is tight with the board it self. ( no big movements)

Graphics card is GeForce 315.
 
Theres no fan or anything on the card, its just a simple card, no casing or anything flash either. Fan inside the PC is clean and running fine too. Any idea why the PC needs to go through the present routine of being plugged into the graphics card first until it restarts before I can switch to the mother board? As in, if I just left it plugged into the mother board the screen would just remain black until I plug it back into the graphics card

Remove the graphic card from its slot and you should be able to use just the motherboards graphic card.

 

EDIT : The GeForce 315 does have a fan and heatsink. They should be facing downwards to the ground.

Are you sure its the Graphics?

 

If you look at your list posted, when you took that info your system was using 91% of your available RAM, I would assume that your system  was just idle when you took that, it looks like something is running in the background or something.
