Thank You for informing me that the two issues are unrelated.
Now that you say that, I must have pulled memory hundreds of time with no issues.
I bought the disk pack from HP to try to reinstall windows.
However, since the computer locks up on boot, at that windows logo, I can not access the cd drive.
I try to boot to the drive but it will not.
I then download, on another computer, the Ultimate Boot CD.
The computer will boot to this CD and I have run a few diagnostic programs. ( I think in DOS mode)
I still have not learned much, I guess I do not know which test might tell me something.
