Follow-up on the HP Pavillion computer:
(photo taken just as I was starting, during the power supply change)
I had changed the Power Supply (250 to 600 Watt), I also increased the RAM memory from 1 GB to 3 GB (all new chips), and I made the original Seagate HD the slave and put in a new Maxtor HD as the "master".
During this time I had to reinstall windows XP Pro three times. (I lost my smile very quickly!)
A good deal of the issues had to do with the combination of faulty RAM chips and an underpowered power supply. Yesterday though the slave Seagate drive began forcing the blue screen of "pre-death" then stopped working altogether.
Now I have a very nicely working HP computer with essentially two thirds of its parts replaced. It's probably the nicest computer in my office. I think this will be the last HP computer I'll be purchasing in a long while!
Oh- about the HP screen. Maybe one day I'll take it apart; maybe not. I'm using another flat screen in the meantime.
