Yesterday I decided that I should begin overclocking. I have a Biostar TForce motherboard so I should have had zero problems. I used the Biostar overclocking program. I upped my FSB and hit enter. Then my PC locked up. My only option was to restart. I held in the buttom and booted it back up. Once back in windows I clicked on the biostar overclocking programs. My PC locked up again. Just to test it again I tried using the programs once more. I locked up a third time. Believing it was a corrupt file I uninstalled it and then reinstalled it. The next thing I know biostars hardware monitor tells me that the CPU fan is dead. I checked the fan, it works fine. I checked Speedfan and it too said that the CPU was at 0 RPM. Infact it also reported that all my fans were at 0 RPM. Fearing dead sensors (I have a faulty heat sensor. It constantly stated that my case is at 127C and never changes), I checked the bios. And guess what it the sensors do work. I've tried updating my biostar tools from the website, and I've had no luck. IF you can help me please do. Thanks, I appreciate it.
