I sold my 3 month old system to a guy last week. I have run this PC with iRacing for the three months with no issues @ 1080p resolution. Before I shipped it out I loaded Windows 7 64bit Pro on a new 2TB Hard Drive as I did not sell the machine with my SSD. I have loaded Windows a thousand times (I have been in IT for 15 years). I loaded all drivers, Windows updates, Adobe products, and the Norton Antivirus trial that came with the Motherboard Disc. Everything appeared fine. However, the guy has had nothing but issues with the PC since he received it. Randomly the Desktop will fill up with black dots. Often shortly after that he will receive a message stating the Video Drivers have stopped responding and have recovered. Occasionally, after that it reboots and he gets Bios message stating the overclock failed (I read up on that and I guess it can be displayed after a hard crash. Its not overclocked and the BIOS has been reset to defaults). I included a couple of pics and a video below. I remoted into the PC, removed the Catalyst Software and removed the video drivers. I then reinstalled the CCC software and rebooted. When running Furmark, we begin to see the black dots again and some other goofy things, however Furmark continues (no crash) and the results FurMark gives is about what is expected for the video card (no drop in fps, no excessive heat, etc). I had him remove and reseat the video card, had him switch to the back up BIOS on the Video Card. Had him reseat the RAM, made sure the processor heat sync was still attached (diagnostics show good cpu heat). He did install iRacing and that installs DirectX 10. I have read that a bad install of Direct X can cause issues, We have since uninstalled Direct X. However I am not sure if the uninstall pulls DirectX off. And if it does, how clean is the uninstall. At this point I am about to have him reload windows, but I am not certain that will do any good. This was a perfectly running machine before I shipped it. There was no evidence of it being handled roughly or dropped. Any Suggestions?? PC Specs are Below
