Upgraded my computer now it wont boot

I have replaced the case, motherboad, Chip and Memory in my computer. I have kept the CD drives. floppy, and hard drive. The motherboard has everything onboard (Video, NIC, sound....). When I boot the new computer with the old drive, I see the WIndows XP logo screen for a few seconds, then the system reboots. I tried that several times with the same result.

I booted in safe mode and was able to get to the windows desktop. I tried removing all the old drives from the device manager like the display, sound, network. Then I rebooted in normal mode and still it just reboots.

So, I decided to use the Windows XP cd and do a repair. The repair did what is was supposed to do, and then the system rebooted, but still only a few seconds and it rebooted again. Now I cant get into safe mode because I get a message saying Windows cant run setup in safe mode, rebooting.

I can still put the drive back in the old computer and it boots fine. I believe its a hardware conflict.

If I boot in the old computer, is there anyway to delete all the devices so that windows reinstalls them on the next bootup? Or is the registry setting that will force windows to rebuild the device manager?

Or does anyone have any other ideas?

thanks

Ray: When you replace the motherboard on a computer, you have to format the hard drive. Your hard drive is setup for the old motherboard and that is why it is not letting you bootup. You need to fromat the hard drive, and reinstall XP so that you start fresh. After you get XP installed then you need to use the CD drivers disk that should have come with your new motherboard. Hope this helps.

 

I have done this before. Last time all I needed to do was a repair and it worked. Did I just get lucky? You mean that if you upgrade your motherboard, you must reformat the hard drive and lose everything? There is no way around it?

If you get lucky and all the chipsets are the same it works, but very seldom. ed

 

When you replace both the mobo and the processor you will have to reformat. If you can, stick the drive into a friends computer as a slave drive and backup all the files you want to save onto a CD or DVD or flash drive or whatever

 

Actually, I have replaced many a motherboard with different chipsets, and typically one just needs to do a repair install.

If you were to hit F8 before windows starts booting, and select "Disable automatic restart on boot..." option, then you should get a BSOD error message. What is the 0x00000xx code?

Presently at work, i'm doing an experiment to see if there is another way, but doubt this will work.

On a rare occasion, I do indeed have to do a rebuild, but, I always backup my data.

 

I know its possible to replace the mobo and not have to reformat (i just did) but not when u replace the processor too. Actually, dont u have to reformat when u replace just the processor?

 

Even in that situation, I didn't have to. I've tested this multiple times. But, this was in my environment, not others.
Replacing the cpu, is rarely a rebuild issue.

Love to know what the BSOD error is.
