I have a ripple in my screen that makes it look shaky and unstable. What could be causing it? Also my computer freezes quite frequently, I have run several spyware/malware programs with no results. Could this all be connected to the same problem? I have an Emachine t6524, Windows XP, AMD Athlon 64 Processor 3500+, ATI Radeon Xpress200.
1) Your refresh settings are too high try lowering them.How to change your refresh rate in xp
2) heatsink on your builtin video card is loose or video chip is damaged requires you either get a new motherboard or install a new video card, also you may want to check for bulging capacitors on your motherboard.
2) bad driver or malware causing the lockups and too high of a refresh rate.
