I have an HP Laptop, 4 years old, running Vista.
Not long ago it crashed and won’t start.
*******************************************
Call HP , get a OS reload disk , buy a new hard drive and reload..
While you’ve got it open bump the memory to the limit.
I called Hp 1 month out of warranty on the keyboard issue. I found out later that it was an known problem and the “work around” was to remove the battery and re-place it. There was no help from HP. Just a run around.
Now that I have this machine up and running I’m afraid to turn it off or attempt a restart.
