Here's what happened. I got home today and my sister told me the com wasnt working, i thought it was another one of those silly things again, but when i turned on the system, it said:

"File System32\DRIVERS\isapnp.sys is missing, enter windows setup and press 'r' to repair"

So i did, I returned the CPU back to stock speeds and booted up from the windows XP CD and halfway through loading the initial files to start the setup, it said:

"setupdd.sys could not be loaded
Error Code 4
Setup cannot continue press any key to exit"

I loaded up my Windows ME boot disk and tried a format with the command:

format c:/u/q/s

but being the software retard i am, it didnt work cuz my C drive is a NTFS partition and i couldnt find the real C drive anywhere.

My sister has data on a partition on that hard drive so i cant just delete the partitions and start again from RAW.

I tried the windows setup again, but then i got a blue screen halfway through loading and it was some kind of memory dump, then it said something about my bios not supporting something forget the name now, starting with A.

If i try the boot screen, i cant get into safe mode nor the last setting that works as it shows the file missing message again for all of the options.

Can anyone help?!?!

Thanks

The errors look to be hardware related, so check that first. Try a bootable RAM test like memtest86. If the RAM is causing the errors you may be able to replace it and use the OS disk and either repair or reinstall to the same partition. If you have a spare HDD, install to that on a temporary basis to recover files, since it's safest not to write to the original disk.

I think Xaotic is right on target with his suggestion to check your hardware for problems. In addition, the following MSKB article deals directly with the error message you're receiving...

Setupdd.sys could not be loaded. Error code 4.

Thanks guys, very much appreciated.

I took out the ram, the one i just bought to upgrade my sister's computer and the windows setup loaded up just fine and i replaced the damaged file in windows, but it seemed the whole thing was too badly damaged to boot up. The couldnt find file thing didnt show up, instead i see a black screen right after the windows XP loading screen shows up. Im reinstalling windows over there now as i type this.

I think the ram gave out since i was overclocking my sister's com, starting out 1:1 120fsb (the ram was Samsung PC2100 256MB) and increasing it in 3fsb jumps every day and doing Prime95 for the whole day for about 5 days or so at SPD timings, which is 2.5-3-3-6. So continuous Prime95 for 5 days must have fried it. To think it would have happened maybe 8 months later when my sister is in Australia and im in the UK if i didnt stress test...

Thanks guys for all the help or i would have ripped my hair out in frustration over this.
