My Probook 4520s AMD Display Driver keeps freezing

[zoommama]

I have an HP Probook 4520s laptop, running Windows 7 64 bit system.  It is almost 1 year old and for 1 year I have been trying to find out why my AMD Display keeps freezing.  The symptoms are as follows:  I open my Windows Live Email program.  I work away happily.  Boinnk, the mouse doesn't work.  Boink - the scrreen flashes and gives me heavy black line.  I am unable to do anything except x out of the windows live mail program, and then start > program back in.  The other symptom is when I am on line on the internet.  I use IE Browser most uptodate version 9.0.8112.16421 - 64 bit edition.  I have contact HP at least 6x to find out if there is a new driver for the "AMD Display".  I have downloaded what appeared to be solutions to the AMD issue and have followed to the letter the instructions to run these "fixes".  I continue to have trouble with the AMD Display.  I phoned HP a few weeks ago, and spoke to a lady in China.  She directed me to the exact pages I had already been, but I humored her.  She pointed me to the Graphics Display to download, which I did.  I was able to get something called Catalyst to install, and run successfully.  But the next time I went into Windows Live Mail - Boink - AMD Display stopped working, and later on a website again the system freezes up.  Obviously there is still a problem.  Now here's the funny thing - the lady in China said she would leave my trouble ticket open for a few days in case my problem returned.  Since I don't work exclusively trying to fix my computer day and night it was about 3 days before I had an opportunity to think about gong back to HP and report that their fix was not yet working.  But wouldn't you know it - I got an email that morning that my help number had been closed.  Now I have to start all over again with the process.  HP  - why don't you just tell people that you will replace their computer with a working one?  I am now so close to my warranty expiry that I risk having to pay for further support on this matter.  Closing my trouble ticket is just simply unacceptable.  If anyone has a solution for the AMD Display for HP laptops, please post it in WIKI Encyclopedia as well, because obviously HP hasn't got a clue.  HP - if you have a clue and a solution, please stop treating your customers so poorly.  I look forward to receiving a new laptop so that I can dump all my contents on it, and send this piece of junk back.
