For the past couple of months i've had the problem of my computer screen randomly going blank. It's not the monitor because all sounds stop too (it's happened while I was listening to music). I thought it was my graphics card (GTX 550TI) because a couple of times when it happened Nvidia said the display driver stopped working and was recovered.
I tried updating the drivers and that didn't help so I got a new graphics card (Radeon HD 7770) but my system is still crashing. I even re installed Windows 7 completely to start over fresh but the crashes still happen. I've taken a look inside my PC multiple times and nothing is loose/broken. I have no idea what's causing this and it's really frustrating to have my PC crash randomly. The only error message i've gotten is from the Nvidia control panel so that's why I assumed the graphics card was responsible. However, it clearly isn't.
How can I test all my parts to find the problem? There has to be a solution and this crashes are driving me insane!
And this: http://i.imgur.com/Bd6Ur.jpg (Sorry for bad lighting) was still behind where the tab was. I assumed the whole tab broke off in one piece but I guess I was wrong. I took it out but i'm not sure if that was the problem. Is it possible that was the problem? Maybe that little piece kept the card from going in all the way?
tihs is the part that hold the card in place in the slot check if there is nothing left from this clip that will not make the graphic card seat correctly in the pci-e slot that could cause the crash see if you could rma the motherboard for that or you will have to get a new board to avoid crash
