My laptop won't start up

So my laptop IBM thinkpad I think T42, will not start. I pres the power button and the home screen that says "IMB and under "thinkpad", but then a message saying

"Windows could not start because the following file is missing or corrupt :

System33\DRIVERS\pci.sys

You can attempt to repair this file by starting windows setup using the original setup CD-ROm.

Select 'r' at the first screen to start repair."

Zoe, before you run out and buy a new HDD ;) A HDD error does not tell you that your PCI,sys file is missing or corrupted. Check things first, it usually means that the actual file system System33\DRIVERS\pci.sys is really corrupt or missing. It is possible that there is a problem with a piece of hardware that is connected to your computer, this is common with a new hardware install, or a new driver. Check on here to see what Microsoft has to say.

You can attempt to repair this file by starting windows setup using the original setup CD Rom.

Select “R” at the first screen to start repair.

Make sure that you do not have any new hardware plugged into your computer. If the file is missing or corrupt you can replace System33\DRIVERS\pci.sys by restarting your computer with your Windows XP disk in it and choosing to repair.

If you can start Windows, try safe mode, simply paste the file back into the Windows/system32 directory. Even if it is still there, it may be corrupt. Of course, you can also choose to install a new copy of Windows which will cause you to loose all your previous data, but it will fix the error for sure. Hope this helps, good luck.

It's either a corrupt or a dead hard drive

A good way to find out is to get an adapter so you can plug it trough the usb of another computer. If the other computer doesn't see it or anything this mean you got a dead hard drive.

If you are lucky and you found your files back there is programs that can help you get you data back.

If you don't care about your data you can just boot your computer with a windows cd, delete the old partition and reinstall windows

How would this fix your presumed corrupt or bad hard drive "just boot your computer with a windows cd, delete the old partition and reinstall windows"? How can you delete a partition and reinstall Windows to that?
