I have an HP pavilion desktop running win 7. last year I started getting 'imminent hard drive failure' warning during boot. advises me to backup disks and replace them. f10 to enter settings, f2 to continue. first time I saw this, I went shopping and bought a new hard drive. now I get it regularly and suspect another issue other than the new hard drive. it does stop the boot up until I hit f2. any thoughts?
