Windows 7 wont start without clearing cmos... Need Help

post #1 of 5
Thread Starter 
A few days ago my friend told me that his computer would not boot up anymore. I went over to try to get it to work and when I started the computer it posted normally but when it gets to the "starting windows" dialogue it freezes and no colored orbs appear. After Clearing the Cmos, the message "cmos checksum error" appeared with the option to restore settings to default or go into configuration. After restoring the settings to defuault Windows booted up without a problem. However, when the computer is shut down or restarted the same problem occurs and you have to clear the cmos to get it to start up again.

Apparently this problem started after my friend hooked up a new 1080p monitor to the computer in addition to his 1680x1050 monitor (he had previously used an HD television as his second monitor). He said that after he had hooked up the monitor when he started the computer it prompted him to choose an operating system (although the only choice was windows 7) and he couldnt restart after that.

I have tried every setting that seemed relevent in the bios of the computer with no luck and have thought of reinstalling windows but havent yet. The rig is a Gateway LX6810-01 with an upgraded GTX460 SE that my friend made me install even though the rig falls short of the recomended power output by 50W.

As he has to now leave his computer on 24/7 because he's too scared to clear the cmos by himself, any quick replies would be greatly appreciated.
Thanks

Sounds like a bad hard drive or an OS error. Try repairing the OS with startup repair. If this doesn't work then it may be a bad hard drive.

Could run a check disk on the drive. Or maybe try reflashing the bios on the motherboard.
