My system ran fine for almost 4 years. Then the other day someone told me to overlock it. And all I did was went into the bios, im pretty sure I didnt change anything, but now my computer doesnt work. When my computer starts to boot windows it often shows that "last working configuration" and then it tries to boot and restarts and does it again. A week before that I got a blue screen on startup (pre os) saying bad driver or looping driver and was wondering if that could be the problem. Any ideas? Thanks in advance
