About a week ago, my wife got a blue screen (I never saw it) and the computer crashed. I have not been able to restart the computer since without resetting the cmos jumper every single time.
If I try to start the computer by simply pressing the power button, the fans come on but the boot sequence never begins and not information is shown on my monitor. When I unplug the PSU cable from the PSU and clear the cmos jumper for about 10 seconds before placing back in the proper position, I can then start the computer and it will boot. However, since the cmos time was reset I have to select F1 to enter the BIOS setup or I can press F2 to select default settings.
If I press F2, then Windows 7 will successfully boot. If I press F2, then I enter the BIOS. When I save BIOS settings the computer will attempt to reboot. However, the computer will not boot again unless I clear the cmos by resetting the cmos jumper.
The only way I can get the OS to successfully boot is to reset the cmos jumper every single time.
I've talked with others about this and no one I've talked to have ever come across a problem where the cmos must be reset every time in order for the computer to boot.
I don't know a lot about hardware. Could this be as simple as a low cmos battery? Is this likely a motherboard issue? Has anyone seen this (or a similar) problem before? Any suggestions would be very helpful! Thanks!
