Missing or Corrupt file! HELP!

I have a compaq presario sr1000 desktop PC. It had been randomly turning itself off for weeks but i just ignored the matter until one day when i turned it on i got the message:

Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM

From what ive read on other sites, i have an OEM-installed operating system so there is no windows XP disk (and rather stupidly i did't make any backup disks although i have now learnt my lesson). Also, none of the F keys are working appart from F1 which loads the BIOS menu thingy.

What do i do?!?!??!?!?

    So your saying its pretty screwed then? Just out of interest, if i bought a copy of windows XP or Vista do you think that would solve the problem if i was able to install a new OS again?

    p.s thanks for the quick reply!

Windows\system32\ntoskrnl.exe filie is missing or corrupt.

need to reinstall windows cause the system files for the operating system is corrupt.

On your compaq, keep pressing F10 as you turn on the computer and that should take you into the factory restore.

If you can't get into that then you'll need an operating system cd and then download the drivers off of the compaq website:

Compaq Presario SR1000 Won't Turn On

The power on buttom might be it. Before doing anything else, check and fix the power ON button. I have a tower that gave me the same trouble. The Power On button somehow was out of place. Once I aligned it, the tower worked again. Good guess..! Good luck

Winnt_root>\System32\Hal.dll missing or corrupt:

if you have a windows cd you can do a system restore from it or at the boot screen some computers have a system recovery so you can use system restore without a disk, if you can use system restore, restore your computer to a earlier time and that should solve your problem

<windows root>\system32\hal.dll is corrupt or missing

See if you can get into safe mode. If you can't then your system files are corrupted and you'll have to restore your computer back to factory defaults.

I believe on your compaq presario they have a built in factory restore and its either accessed by the F10 or F11 key when you first turn on the computer. You'll know when you first turn on the computer at the compaq logo screen.

Let me know if I can help you further.
