Greetings,

About a month ago the time on my computer started slacking. After some research I found out it had to do with the CMOS battery being faulty. After replacing the battery I started up my PC and at the point where the windows logo comes up, it freezes halfway and immediately shuts off.

My specs are:
OS: Windows 7
Core: Intel I7-2600 @ 3.40 GHz
Motherboard: Dell Optiplex 990
Videocard: Nvidia Geforce gtx 750
Memory installed: 12 Gigabyte
Hard Drive: Seagate Barracuda 1000GB

I think I have rooted out that it is not a faulty hard drive. This is because I switched the hard drive with another and the same problem occurred. So I speculate the problem lies with the motherboard. Now I hope to god that it is a software issue and not a hardware issue due to the fact that I just recently bought this computer in the summer and I'm not the lavish spender type.

I have tried to startup the computer with 2 different CMOS batteries without any prevail. I CAN startup the computer under System Recovery though, which mean I can access the Command Prompt or the System Restore option.

I hope I am not the only one having to deal with this issue, and if anyone has any advice whatsoever, I would be pleased to know.

Many Thanks,
Ron

I found that my system automatically switched the BIOS from AHCI to RAID after replacing the CMOS battery. I switched it back and it all starts up again.
You should write down your BIOS settings before removing the battery as any custom settings will be returned to default settings by removing the battery. A common setting error is SATA has a default setting of [IDE] and a custom setting of [AHCI] which causes the PC to fail to boot with the default setting.
