Vista SP1 Checksum Boot Fail

[Tumps]

Doing a fresh install on a laptop. Install Windows Vista Home Premium. Install SP1 from standalone installer. It installs and restarts, then does the boot updates.

Then it restarts again and before I get any sign of Windows I get this error "The file is possibly corrupt. The file header checksum does not match the computed checksum."

I ran a startup repair and it found nothing. I did a system restore to before SP1 and it did nothing. I ran a full chkdsk on the drive and it found nothing. I re-installed Vista serveral more times after that and tried different downloads of SP1 and each time the same error appears after installing SP1.

Any ideas?

Need more info then please ask!

SOLVED:

It appears to have been a faulty stick of ram.

Have changed out the ram and it works.
