Okay, this is odd. I'm testing a new build. Intel i7-930 on a Gigabyte GA-X58A-UD5 with 6GB Corsair RAM and Win7 64bit. I have been testing with Prime and getting pretty good results but I just discovered LinX and thought I'd give that a try. I installed it and ran it for a while today and it ran fine for quite a while. I did 20 runs withe the default settings. Then I beefed it up a bit. I had to stop it to do something else. Then when I started it up again and came back after a bit it was still running but no results rows. For the settings I had there should have been results rows. I hit the stop button and nothing happened. Still blinking time in the status bar of LinX. So I closed it and rebooted. Same thing. It says it's running but nothing happens. No increase in CPU temps at all either. I tried Prime again and it does what it's supposed to do. I get CPU 100% in task manager and temps go up ni CPUID Hardware Monitor. I even tried uninstalling LinX, rebooted and reinstalled and get the same thing. LinX doesn't do anything now. Does anyone have any idea why this would happen?
