Push power on goes through all the POST acts like Windows is going to load...reboots
Knoppix live CD..POST...starts to load desktop...reboots
have disconnected every external device except: MOBO,1 stick memory,CDROM
removed all PCI cards except video,replaced video with known good one.
Tried new power supply also.
If i put the Gateway System Restore CD in it goes through all the motions of re-installing the partition image and reboots..and reboots...and well you know.
So - BIOS, MOBO or ? All suggestions welcome because i'm baffled.
:thumbsup:

It is rare that bios gets corrupt but not unheard of. You may want to try setting the bios settings to factory default and se if that helps.

Maybe flashing it to the latest bios, or to the current one to make sure its not a corrupt bios.

Other than, it may be the mobo.

Law, what it sounds to me is that you either have a corrupted MBR or boot sector in the windows partition. Have you done any partitioning, or installed/uninstalled any Operating systems lately?

The best way to solve this is to follow the PC boot from start to where it stops. The first thing that happens when you push the "on" button is the power supply runs a check on itself. If it has enough juice it passes the all good to the cpu. The cpu will kick the ROM BIOS in, whoes purpose is nothing more than a bridge between the cpu and the system BIOS. The BIOS grabs stock of nothing but monitor and keyboard, that's all you need to work with incase of complete drive failure. If your Bios is loading, good news, the motherboard/cpu are fine. The BIOS looks for the MBR (something like 0007c) on the very front of the Hard drive. If you're seeing the screen with F1 for Bios F10 or something like that, great news the Bios is fine because once it passes the JMP command, the BIOS does nothing else.

The MBR is like a bootloader. It's job is to look for the partition of the correct OS. Once it finds the 55AA, it's job is done. This is where the actual OS startes. If you're seeing the Boot screen, she's gotten this far. The worse is over. The motherboard is fine, the Bios is fine, the MBR is fine. From that point the kernel and boot sectors just pass a few commands back and forth checking the drive making sure the system is stable enough to boot. If you're getting to the Windows sign in, I'm wrong again, it's not the boot sectors, it's got to be something in the actual Operating system files.

Have you tried F1ing into the BIOS and booting in safe mode?

If you figure it out, post back and let us know what it was, if not than we'll put our heads together and figure it out.

According to hwinfo (good program by the way)
32 bit integer: internal error
So the CPU is bad after all and not until the 32 bit OS (windows and knoppix) loads does the CPU fail.
Just when you thought you've seen it all - you haven't .
Thanks for the tips guys.
