Hello to all and thank you in advance for your time. Here we go 2 weeks ago I was replacing Compuaq Presario  AMD 64 2/4 Gg SR1365CL . My motherboard cpu FAN with a new one and the cpu came out with the heatsink bent some pins and after that the motherboard would not work,  I am or was using Xp service pk 2. Now I have purchased another motherboard with a p4 3.4 gig cpu and after finally getting passed the system/32 missing/ error and going into the RECOVER system  using the dvd recover disk I made years ago I now have a ntldr error and cant get passed it I cannot get an option to go into safe mode or any other mode, really dont want to lose  my hdd info, I have a boot disk on the way as all my os info other than the dvd backup is on the Hdd partitioned off what do you computer gurus sugest I do.  I would be more than happy to call or have you call me on this matter if it is easier. Thanks again for your time   AD you can't just swap motherboard and cpu and expect Windows to work just like it did before. You have GOT what is really a new computer.

You should start again and reinstall Windows.

Or you may get lucky running a repair install...

Repair Install of XP

I suggest reading it through before proceeding and printing it out for a reference...Thank you for your time Patio will try it ....When you replace the motherboard the computers bios does not kinow what hardware you have installed and this can be a PROBLEM. it is a good IDEA to try reinstalling windows and starting again.programming_pat that is not correct. The BIOS main function is to initialize the hardware and startup the OS boot loader. The BIOS doesn't care if you change hardware as long as the bios supports it. The problem here is that Windows can easily get messed up if you do major hardware changes. This has absolutely nothing to do with the BIOS.
