My PC is going crazy and now so am I. A couple months ago my Gateway GT4016 (running Win XP home) started going haywire. It has a nVidia Geforce 6100 GPU, AMD Athlon 64 3700, and 1Gb DDR ram, After awhile the entire screen gets zigzaged and also locks up the PC. I have tried everything. A different monitor, PCIe video card. it seems to only do it when it has been on for several hours or i hook up any form of internet (wired or wireless) including installing a new 10/100 card. I have attached the latest pic of the issue. So far I have tried what I know but nothing seems to work. I have also done all the software and driver updates.
