Reboot loop trying to upgrade to Win7 Pro X64

Microsoft Windows 7 professional 64-bit

Specs: Windows 7 Professional 64-bit, Intel Core 2 Duo E8400 3Ghz 6MB 1333FSB / Corsair 4096MB PC6400 DDR2 800MHz (2x2048MB)
I just tried to upgrade to Windows 7 Pro 64 on my PC (previously running Windows XP Pro 64). part way through my install it tried to reboot and has now entered a continuous reboot cycle immediately after flashing the initial motherboard welcome screen. None of the keyboard shortcuts work to access the BIOS, boot menu, etc. It doesn't seem to even get far enough to connect to the hard drive or CD ROM. I also don't see any error messages, it just reboots without warning. Any ideas what's wrong/how to fix it?

If you cannot even get into BIOS with the keyboard, then this means your keyboard is

1) connected to your PC thru USB and legacy USB support is
not enabled in BIOS.

2) defective.

3) working but you do not press the correct key for BIOS entry.

What you can do now is,

1) find an USB/PS/2 adapter and connect keyboard to PS/2
port on M/B.

2) Replace defective keyboard.

3) Press the correct key for entering into BIOS.

After your keyboard works, start your PC with your Win 7 disk and try to make a clean installation of Windows 7. You cannot upgrade from XP to Win 7. When you boot to Win 7 disk, choose Custom (Advanced) installation and then select Drive Options, Format, etc.

Hope the above helps.

Thank you for you input, SuatCINI.

Unfortunately, I have tried the steps you have suggested and they did not work. I already tried replacing the USB keyboard I was using with a PS/2 keyboard that was working successfully on another computer and I still could not get past the welcome screen.

Also, I can assure you that I am pressing the correct key for the BIOS. Not only do I access the BIOS on a fairly regular basis, but the keyboard commands are written on the bottom of the welcome screen. I have also tried additional keys that are not written on that welcome screen to be sure.

The main problem here is that I don't see ANYTHING but the welcome screen. It is as if the computer begins to restart as soon as it shows the welcome screen. I do not think that computer even has time to load the BIOS before it restarts itself, let alone access any of the drives connected to it.

I am beginning to assume it is a hardware failure of the CPU or motherboard, but I am hoping that there is a better solution to the problem than replacing the major components of the system.

P.S. I realize that I used the word "upgrade" when referring to the procedure that I did when attempting to install Windows 7 on my Windows XP machine. However, I did choose the Custom Install option an proceeded with that as instructed.

If you cannot even get into your BIOS, do not overlook a RAM error/fault. Run Memtest to be sure. If it runs at all, but returns errors, you have your answer. If it will not run at all, try removing RAM and reseating only one stick at a time and retest for each stick. If it still will not run at all. it might be a motherboard or BIOS problem. If memory tests Ok, Make sure your DVD drive is first in boot order, and boot to your Windows 7 disk and do a full format and start completely clean. If it boots to the windows 7 disk, but will not format, suspect a bad hard drive. To test hard drive, use HD mfg.'s utility.
I hope something helps.
