I am having a problem for the past 3 months where only after the PC has been on for about hours, windows will "freeze" in a very bizarre manner. I have run windows memory diagnostic over night and it found no problem. I have not enabled any overclocking. I have also installed all of the latest drivers and updates. I believe the motherboard may be defective, a brand new gene z gen 3 that i just built up.
Let me describe the freeze: i have only observed this behavior after the computer has been on for 12-48 hours. Everything will be working fine and then suddenly links on a browser window wont work at all. Then i will try to open task manager, which will not open. I can try to open apps from the start menu, but they flash for a second, and then disappear without opening. After i have tried to open several apps, explorer will freeze.
What is strange is that i can still move the mouse. I can still hear sound in the background. The numbers and animations on my widgets continue to work fine. But everything is locked up. There is no hint of the problem in the logs and since i cannot open task manager, i cannot troubleshoot individual programs.
Pushing the reset button is my only option, and the computer reboots fine and then continues to work fine for 12-48 hours until the next freeze.
The bottom line is that my last system was stable 24/7 for months at a time, and this new asus based system can barely make it for a day or two without a restart! Not very encouraging!
I have 4x4gb 1600 ram g skill ripjaw. configured XMP in bios.
CPU is 2500k at stock clock.
I have an ATI 6950, intel video is disabled, latest 12.2 drivers.
Power is antec 750W high current gamer.
My storage is 2 x 160gb intel 320 series ssd in raid 0. 2TB external HDD.
DVD burner, card reader installed.
Silverstone tj-08 case.
Windows 7 pro x64 sp1 all updates w/ security essentials and malwarebytes.
I am no stranger to computers or overclocking. This problem is proving to be almost impossible to diagnose though.
My 5 year old qx6700 socket 775 was rock stable 24x7 overclocked to 3.4Ghz. I used the same video cards i have in the new system. I actually went from tri fire to bi fire in the "cross-grade" (I can't really call it an upgrade yet until it's stable)
Any advice or help is greatly appreciated. Otherwise i plan to return the board for a refund and get something else.
I did a completely clean install of everything using drivers from the website. Like i mentioned i have been building my rigs for a long time and never seen something freeze like this... I plan to RMA this week unless i find a solution before hand.
