Hi, thanks for asking about what I'd like to gain. I was getting blue screens and overheating and I ran diagnostics on the CPU and RAM and all was good. So I figured I'd replace the MB. But, here's the kicker. I determined that a LED light plugged into one of the USB ports was causing the problem. I unplugged it and now there's no more crashing or heat issues. However, I do get an 03 error on the MB which is an OS wake vector call. Not sure if that's an issue. One other problem is the computer won't sleep automatically, only manually. Any suggestions?
