My computer is comparable with the best System76 desktop; one step down from best graphics. My problem is that my screen/computer freezes up, goes gray and then recovers. I did not expect this given what is in this computer. I ran a test, backblock and found no errors. Graphics (GeForce GTX 660 Ti/PCIe/SSE2). Memory (62.8 GiB). Processor (Intel® Core™ i7-3960X CPU @ 3.30GHz × 8). Disk (876.9 GB). OS (32 bit). Using NVIDIA binary Xorg driver, kernal module and VDPAU library-310 (proprietary, tested). I've thought that the problem was with Thunderbird but the freeze up happens other times too. I have one other option for a graphic driver, 313. I've thought about over clocking my processor. I will probably move up to 64 bit OS with 13.10.
Has anyone experienced a similar problem with a similar system?
