Windows 7: Windows 7 Restarts Computer During Last Steps

Windows 7 Restarts Computer During Last Steps

I have recently upgraded my computer with a new Mother Board, CPU and RAM. Upon successfully installing all 3 components I booted my PC. Firstly, everything was going well, it loaded in Windows 7 like always and I then successfully installed the new mother boards drivers with no errors. At the end of the installation it advised me to restart, I did & then because I wanted to try my new setup I booted on of my most demanding games (BFBC2). After playing the game for 4 hours I decided to go to bed. I woke up in the morning booted my PC only to find that once it got to the "Windows 7 Loading Logo" the computer would reboot.

My first thought was, oh just a one off reboot. As the computer rebooted itself again, the same thing happened. The instant it got to the Windows 7 Loading logo it reboots. My first thought was the OS, so I put in my Windows 7 disc, booted off the disc, deleted both my partitions on both my hard drives and reformatted. This is where my problems began to worry me. The first stage of the installation "Copying Files" It goes from 1 - 100% in less than a second, instantly goes to the 2nd installation. It continues through all of the installation smoothly. Once it gets to the phase at which it needs to restart the computer it does. Then it boots normal...load's Windows 7..the logo comes up and under it reads "Setting up Registry Settings"

Then *REBOOT*, I'm tried Windows XP & Windows 7 on both Hard Drives. To no avail.

I've even had my computer IMPOUNDED as such at my local computer shop (the same place I bought the components) and they did find a fault on my Mother board and gave me a new one. I brought the new one home and the same things kept happening. I've tried the whole "replace DVI cable with VGA" to no avail. I've tried booting in Safe Mode but that's impossible now as both Hard Drives are empty.

I've actually completely and utterly run out of options. This forum is my only chance.

Try testing your RAM. Download a copy of Memtest86 and burn the ISO to a CD using ImgBurn. Boot from the CD, and run at least 5 passes.

Try resetting the CMOS:

Check SATA controlller setting: Try ACHI, then IDE if necessary.

Test your HD using maker's diagnostic CD. Ditto memtest86 as suggested.

Check all of the connections closely, cables, reseat the RAM, change SATA ports, check for newer BIOS update and that all hardware is registering correctly in BIOS.

As a last resort, remove HD and isntall on another computer. Sometimes returning HD after install, it will start up on problem computer, change out all drivers, and run fine.

Would you know if I could run the Memtest off of a USB?

Also, I cannot boot into Safe mode being that neither of the Hard Drives have a fully installed OS. When I formatted and reformatted the hard drives, it's almost as if they do not get...well, formatted. I tried another test last night, I unplugged one of the Hard Drive's SATA cable and left the other one in (this is the one I know I haven't installed or tried to install Windows 7 on) I booted my PC and it still came up with the Windows 7 logo (and yes the OS disc wasn't in) this confused the hell out of me because I've wiped BOTH hard drives with the XP and Windows 7 boot disc by deleting thier partitions...this should get rid of absolutely everything right?

Cheers for the quick replies,
