Well I am afraid I have some bad news for you, I found your laptop:

But it looks like under downloads they only have software support listed, no driver support for Win7. So I dug a little deeper, and it looks like your model does not support Windows 7. Here is a list of Windows 7 supported models.

I would recommend putting the old memory back in the system and checking the system stability. I like caperjack's idea about knoppix since it will allow you to identify if it a hardware or software issue.

My Rule of thumb is if I upgrade hardware or software and I get undesired results afterwards. I uninstall or remove the new hardware to see if I get the same results.

Shepherd,
F11 is for IE to go full screen and back. Try right clicking to the right of help, on my computer XP it brings up toolbar options. btw what os are you running?
