Easy RE Vista boot fails prior to loading.

#1
I am trying to repair a friend's HP pavilion s770n slimline running Vista Home Premium.
Startup repair fails.
System restore fails -- a dozen different attempts.
Safe Mode fails.

I am able to boot an AVG linux CD to test for viruses which works fine. No infection.

I purchased the Easy RE ISO this morning but cannot get past a certain point in the boot process. I tried re-downloading and burning to another drive with the same results.

Watching the screen, it bombs out just as HAW loads in the script, but not sure if this is the issue or not.

I did see on this forum where an incompatible video mode prevented booting and I suspect it may be the same issue here as the screen goes blank and the monitor says the mode from the D15 connector is invalid.

Any suggestions? Thanks in advance.
