Hi, I have built a system for what seems a while back now. Was in the process of building a second less powerful one, when got a small issue with the first. The systems won't shut down after waking from sleep, and sometimes goes to Blue Screen. I have updated Vista 64 to SP2 and updated graphics driver, but no fix. I am wondering it is the bios, as I have read the bios has a part in the sleep process. The mobo is a Gigabyte UD5. Are mobo's bios commonly connected in this type of problem?
