I have an HP 620 that came loaded with windows 7 home premium. Of course, I didn't make recovery DISKS. The problem first started with msg of 'failed to connect to a windows service' and then the blue screen with msg shutting down to protect COMPUTER. I DOWNLOADED malware removal software and then was instructed to load recovery disk. Since I didn't have one, I used recovery disk from another windows home premium. However that version was a 64 bit and my system is a 32 bit. Now I get msg of media cable error that flashes and goes to black screen with non-system disk or disk error. I have run the tests for the hard disk, memory, battery, etc and all have passed. When I turn on pc, I get the 'hp invent' screen and press escape. In the f10 bios setup, I have restored defaults and saved change. There is no f11 option for system recovery. Is this just a problem of having to get the recovery disks or is it something more serious?

THANKS to anyone to can help.Bad MOVE to install another version on that PC...now your recovery options are gone as the recovery on this ver. will be different.

I would contact the manuf. and order a set of Recovery CD's...
Only way to get back to square one i'm afraid...
