I was loading a web page that had a picture. The ares where the picture was loading changed to horizontal colored lines, then the system shut down. On reboot I got the 5 beeps that says the LCD is bad. I replaced the LCD but on boot the screen first flashed horizontal lines of red dots, then vertical columns of white dots, then blue screen (related to ATI video). The system would only run in safe mode. To make a very long story short, I re-replaced the LCD and I have replaced the video cable. Same problems. With any AMD ATI drivers installed I get the blue screen. Removing all AMD ATI software and drivers the system will still run in VGA mode but oh so very, very slow. Even just booting seems to take many times longer. Power on to lock screen is 3 minutes and 3 seconds. Sometimes I can see the screen painting from the top going down just using Firefox. This is with a Ready Boost USB flash drive which seems to help overall performance at least slightly. I upgraded to a 2 tb hard drive several months ago (lots of pictures and videos) with indexing turned off. I use the system mostly for Internet, Word, and Excel.
Running the system test (using the function key during boot) the test for reading and writing video memory fails every time. During the test I also get the red and white dots on many test screens and there are two groups of vertical blurred areas, each about 4 inches wide, that are visible on some screens between tests (I never see this running the system in VGA mode).
The processor is an I5-450M, 2.4, 3MB, Arrandale, K0 4PG9N. The system has 2gb of memory running Windows 7 Home. Max configurable is 8 gb. I would like to use the system for 6 to 10 months and then give it to one of my grandchildren. So two questions.
If I upgrade to 8 gb memory, will it noticeably help the overall performance?
Should I upgrade to Windows 10 (non-touch system of course) in hopes Windows10 will run faster?
Thanks for any and all help.
