Hi. I'll do my best to keep this brief. I have a vexing graphics/performance problem.

A video card died on me in December and I replaced it with an EVGA GeForce GTX 760 4gb. I immediately noticed odd behavior of my programs. If I were to load up World of Warcraft, while playing a movie with windows media player, the movie would either freeze or be thrust into fast forward. Open pictures in Irfanview or other pic viewers wil automatically resize and or close. This happens across multiple image viewers and video players. EVGA customer support suggested it was a VRAM problem. In an attempt to fix this problem, to date, I have:
Replaced 4 - 2Gb (8Gb Total) sticks of memory to 2 8 Gb (16Gb Total) sticks Ares G skill Series.
Replaced an i5 CPU for an Intel Core i7 860 Lynnfield
Upgraded my generic 1 Tb Hard Drive to a Western Digital 2Tb drive
and tested two other video cards in the machine. All could repeat the problem, which means it is not the video card alone. I have exhausted my computer know how and seek outside help. I have created a video of the problem that shows what I am talking about, better than I can explain. At the 1 minute mark World of Warcraft goes full screen, and you can see the behavior I describe.

I am running a Vantage liguid cooling system, with idle temps of low 30 C, and active temps of 40 - 55. My ambient room temp is usually warm - jungle hot.
Asus P755 MB
Xion 750 Watt Power Supply
and components mentioned above. I have files that could be loaded for viewing including my coretemp dump, and Nvidia system information. I will provide any information regarding this matter if someone deigns to assist me.
 
Look the only explanation i could find right now is that you changed your processor graphic card, rams hell even hard disk and not the motherboard. There are many things in a motherboard that could go wrong like the SATA ports are not working correctly or the pci-e slot not providing enough band width to the graphic card or not providing enough power or skipping power to processor or the graphic card. All in all motherboard might be be the culprit behind it. Or simply drivers might be doing it but seriously doubt it that they might be it.
