So I flashed the bios shut my computer down replaced the cpu and added a new hard drive today. When I tried to start it, it did not work it just showed a black screen. It didn't even post so I got worried and tried putting the old cpu back in and disconnecting the new hard drive and it still did not work. After a bit of time I figured it must be the bios because i never tried starting it after I flashed the bios, i just went straight to putting the new components in. I even tried another monitor to make sure that hadn't failed for some reason. After a few hours i tried starting it again and it went to an odd screen which I think is the post screen but it skipped the one with the gigabyte s series logo. It said some things about looking at IDE devices but couldn't do anything, but it did let me go into the bios and look around. I couldn't see anything wrong but I set it to optimized defaults anyway and it started normally, but when I tried restarting the optical drive just kept making noises like it was looking for something and I even tried opening it and putting the windows disk in but it just kept skipping over that. So I waited a while and checked it periodically but nothing happened until now when it just started again and yet again it skipped the normal gigabyte S series logo thing but it started fine. I still have the new hard drive disconnected, the different monitor connected, and the old 5600+ back in place. If I remember correctly can’t you take that watch battery out and put a penny in its place then wait a few minutes? I have noticed that for some reason there is a windows update and I can’t seem to stop it so I will flash the bios with the latest atbios utility and leave it on hoping that the windows update does not restart it or at least that if it does it will boot fine. I have another computer I can use to check this thread if anything does happen. All my system specs should be on my profile, and my upgrade was to a phenom 2 720 x3 with a western digital 640gb black 32mb cache which I only added and did not use to replace the older ones. My motherbaord is a gigabyte m57sli s4 rev 2.0 I know this is horribly written but I just wanted to get it posted as fast as I could in case something happened.
