nTune locks up my system..

[cpush]

Recently, and I have no idea why, nTune has decided to hardlock my system when I try opening it. It has worked fine for the last 2 months I've had my system. I started experimenting with overclock combinations and memory timings and wasn't too successful. I noticed nTune would lock up my system, so I set everything back to my previous set up and it still crashes my system, I have re-installed and no luck. Any info would be appreciated. thanks

Might want to check the BIOS and make sure the settings are still at their default. You might also want to check your system for any virii/spyware/malware/etc. On the same lines, make sure none of your other installed software is killing the app, or trying to. Aside from that, I'm not too sure what could be causing it.
