Using OS on a old hard disk on a new computer. Help please.

[Scorpio]

I recently replaced my old 1.6GHz Intel µp and SIS motherboard with a new 3 GHz µP and Intel genuine motherboard. I cannot use the OS in the old hard disk. The system re-boots repeatedly when I try doing it. The problem would be something of the drivers. If I replace all the system32 files the OS opens but I cannot do anything. If I replace only drivers, system reboots still. Can somebody help me and guide to me what files I must replace in system32 or what else I must be doing in order to open a OS in a Hard disk which has been installed with old drivers? Former is as stated SIS and the later Intel.

bro..u cant use it.......as the basic architecture ie proccy and mobo have changed so u cannot run the old OS...what u can do is.....Format(if u can )and install the OS with new mobo+proccy ..or if ur OS is xp then install it again..keeping the old XP ..it will ask wether u want to backup ur sys files etc or delete them....if u donn have any imp files on ur os..then use fresh install

why not... if he just detach the HDD from the old system & attach it on the new mobo system... then at the time of boot OS will (98 2000, xp) ask or the installation disk (path).... & he just has to install the drivers of the new mobo.... thats it... why i am saying this?? as i have done that....

All that you need to do is re-install the MoBo and other drivers.

Start in safe mode, remove all the existing drivers and re-install the new drivers using the CD that came with the new MoBo. But of course, the system may not run as good as a new one. So if you want optimum performance, format and re-install.

I have sevral crucial data and some very important software that I have installed in that OS. I dont have their installation disk and cannot afford formatting. The OS doesn't even open in safe mode. System reboots doing that. But the OS only starts if I replace all system32 files from another newly installed OS. But it's totally flawed then. To my knowledge, I presume it is good enough if I replace several folders of system32 (of the present 2500 files) and not all, for the OS to open without any problem.

well bro dono how u managed it..but when u change mobo proccy....its not only these 2 components are chaged but all ur IRQ's , IDE settings, Bridge controllers , memory settings etc , in short every thing at the base changes...so just reinstall of Drivers wont help much....

any ways..Scorpio as u say u have rucial data and some very important software on the hdd..so what u can do is rename he program files folder ..then reinstall OS...after rename the prog files folder again......well tell u what i am not sure about this method....but worth giving a try...

Your system may not start in windows mode. But try to start it in DOS mode and run setup.exe of windows. That will update/replace all the necessary files. Then try starting it in safe mode and delete all the drivers from My Computer > Properties > Device Manager. Restart your machine and it will start detecting new hardware. Supply the right CDs and things should fall in place.

A clean re-install after a format is any day better. But since you can't afford to do that, try this.
