Cant re-install/fix vista-stuck

[SlithMan]

Ok guys here goes, Last week my pc was fine, I turn it on and get a message saying to insert the DVD to fix a system registry error. ( I don't remember what message it was sorry) So I do and windows boots. I backed up my files that night. Next day windows is acting weird and sluggish, if I try to open my computer or documents PC freezes, it takes a long time to boot and 8 times out of ten will hang on the green loading bar or take an hour to load, my sound card deleted itself as did my cdrom drive. Safe mode either takes forever to boot or will freeze when loading drivers, I tried to re store/reinstall and boot from the vista DVD at startup but i get the message "The file is possibly corrupt. The file header check sum does not match the computed check sum" or "couldn't find boot manager". This happens for the x64 vista disk, x32 disk and my XP pro disk. I tried to reformat in safe mode command prompt and it said Formatting the partition was prohibited. I thought it was my ram at first so bought new ram but still the same problem. I'm also not sure what caused this I do regular virus checks with up to date software, maybe its a bad windows update? thanks

Your best bet despite it being a PITA is a clean install. Force boot from the dvd format and install. If you had a backup from before that time you could just restore it from there, but failing that. Re-install is the way

Thank you for response, how do I force boot the dvd though? I thought thats what I was doing at start up and got the error message.

Dependent on your computer when it first starts booting you hit a "F" key on dell its F12 and you are presented with a boot option.

This is where my problem lies, I start my computer and hit escape which brings up my boot menu, I tell it to boot from the cdrom drive and insert my vista dvd, it says press any key to boot from the DVD, I press a key and get the message "The file is possibly corrupt. The file header check sum does not match the computed check sum" if I restart and try again sometimes I also get the message "couldn't find boot manager"
