This problem I am having is very difficult to describe. When I boot up my computer and it gets to the Microsoft Logo, the background screen is filled with ¼” squares in horizontal lines across the screen. Each boot up is different. Sometimes the squares fill the whole screen and sometimes they fill only parts of the screen around the Logo itself. As I continue to let it boot, when it gets to the Desktop, the right half of the screen (only) has multiple horizontal lines of dashes that seem to move as if there is information being processed. If I have a Window open maximized with information on it, whether it is graphics or lettering, it is distorted beyond recognition on the right half of the screen only. The left side of the screen is unaffected! The cursor Arrow has what looks like a 1” horizontal Barcode across the shaft of the arrow and it stays there even if I move it to the left side of the screen.
Here’s another example: I printed out a draft copy of this message in Microsoft Word in a window that used only the left side of the screen. The printing was normal. I then moved the window to the right side of the screen. The printing was unreadable. I then moved it back to the left side of the screen and it still was unreadable. I then maximized the window and minimized it back and the printing was readable again!
What I would like know is this: Can someone give me information on the procedures to take to find out what is causing this problem. I would like to test my Hard Drive, Video Card, Monitor, and Malware, but I’m not a computer expert, so I’ll need plenty of help.
I have a Dell Dimension 8300 Pentium 4, 2.8 MHz, 1.5 GB Memory. Windows XP Home Edition, SP3.
Please let me know if any other info is needed. Thank You.
