Bad Virus infection. Need help please!

My laptop (Dell MS 1350 operating Windows XP Pro, sp2) became infested with a very bad virus. The symptoms were:
1. many programs did not more open with an error message "..." exe is not a valid win32 application ".
2. no programs of virus removal, including virus removal tool malicious Windows, AVG and other 'free' specific patch programs would be open and run.
3. the computer does not open in Mode safe more.
4. Windows 'last known good start' does not change the situation.
02:05 does not repair Windows (due to no Mode start safe) facilities, now, the computer continues to restart without opening windows. I was able to get a blue error screen "Setup has not found all HDD devices installed in your computer."

The Dell Diagnostic Utility shows no problem with the hard drive or other devices.
How can I get out of this dilemma without having to reformat my hard drive?
Thank you very much for your help.

It has infector of very bad polymorphic file that probably does that.  People with that see many security forums.  It is capable of infecting executable files (.exe) machine and the screen saver (.scr) files. However, the problem is that the virus has a number of bugs in the code, and therefore, it can misinfect a part of the file executable files and as a result, the files are damaged irretrievably. From now on, security experts suggest that the best way to solve this problem is the format and clean install or destructive recovery if you have a recovery partition OEM as the best way to clean out the infection and it's way better and safer to return the machine to its normal operating state.
I know that's not what you wanted to hear, but that's what we have been dealing with lately.
