I had a customer come to me with a computer with a bit of spyware on it. They also informed me that the screen was displaying strange colors and was distorted in some places. I removed the spyware, but the display issue remains. It only seems to appear in Windows Explorer, the security centre, and in IE. I have updated the graphics drivers, changed graphics cards from the original AGP card to the onboard card, to a PCI card. I have run sfc /scannow in case any files were out of order. I have swapped out RAM, the power supply, I have even gone as far as to do a clean install of XP SP3 on a new hard drive, all with the same issue.
I am beginning to believe this is a hardware issue, however I am doubting it for the following reasons:
The problem only occurs when XP is running
The problem only occurs *on specific screens*
The BIOS, boot splash screen, etc is normal
Running Ultimate Boot CD 4 Windows (Windows PE) everything looks fine
Aside from this issue, the system is stable and works great
The machine is a Compaq 3100NX
Any ideas would be greatly appreciated, as I'm running out of ideas. I have posted some screenshots below.
This issue happens on different monitors as well. I have now reinstalled XP again after I removed the motherboard from the case, and the issue still persists. However, this time while installing XP I received the error "Your system is low on virtual memory" about 10 minutes to the end of the install. This I do not understand as the computer has 512MB of RAM (this is my test memory and it has been used in many other computers and passes memtest in this computer without an issue.)
I believe this must be a CPU or motherboard problem, however bizarre it may seem, it really is the only logical explanation left, unless I'm missing something?
