|i have had trouble diagnosing my computer because many problems may have occurred at once.|
it started a few months ago when my moniter would randomly change colors and shapes after warming up. you could see the mouse move, but it did not look like a white arrow, it was a large square with many changing colors inside.
then eventually the computer would not boot, nothing would appear on the screen when the power button was pushed.
i described the problem to many experts and they all came to the same conclusion, that it either had to be the system memory or the graphics card memory.
i ordered a new ati 5750 graphics card and it arrived today. i slipped it in and the computer appeared to boot properly.
This means that the graphics card was deffinately bad.
But there is at least one more problem.
I began installing the drivers.
i had read that there were problems with this driver on windows xp, but that they had recently solved the problem with the release of catalyst 9.11, and i could not find anyone on the many many sites i visited who could say that they still had problems with windows xp after installing catalyst 9.11.
but for me, the installation halted after the file extract every time. i would click install, and the catalyst window would disappear, and when i looked up the installer process in the task manager, it was consuming 0% of total processing power. i waited patiently but eventually rebooted and tried installing over and over again, both from the xfx cd included with the graphics card and from an installer downloaded from ati's site with the same results every time.
after 5 tries a window appeared displaying the message "windows hard error" i kept xing it out and it appeared again and again. i tried to reboot and the computer would not. the computer now refuses to boot from the hard disk, it just continually says "system error, insert boot disk and press enter."
so i ran memtest86, thinking that perhaps my memory was also bad
with both of my sticks in, memtest 86 completes the walking ones test, but then reboots at the 66% marker of the "own address test"
with one stick in, it completes all tests with no errors.
i have tried all combination of stick placement, the system refuses to boot from the hard disk.
