Solve : Strange cursor bug..?

Answer»

Hi guys! Sometimes for no reason my cursor goes crazy ;o he picks randomly textures from the screen and transforms into them Really strange.. searched the whole net and didnt found anything. Who know.. maybe i didnt search enough, but STILL, can you guys help me? My OS is windows 7 64 bit (or 84 i got kind of confused in the last WEEK..) Ultimate version. Cursor over COMPUTER: SPECS for more info about my computer. The bug appears quite often, maybe 3-4 times a week or maybe more. The cursor can change in games, programs and almost everything. I think it happens only when I move it. Really strange..

Hmm.. are you SURE its hardware failure? Can it be something from the software? Cuz my temperatures are fine.. my computer has something like a ventilation control system that controls the temperature by speeding up or down the fan. When I dont use my computer the fan almost stops, so the computer makes no sound If it matters.. and my mouse does that bug even when doing something really simple like moving it.

Is uppose you could try updating the video driver. How do you know your temperatures are "fine"? Have you taken readings?
Try disabling desktop composition for a while and see if the problem persists. my desktop used to do something similar as a result of playing videos using a certain hardware-accelerated codec, (temps were unaffected) but disabling desktop composition fixed it. (I later discovered that not using the aforementioned codec/player option made the problem go away).

I noticed that this bug accures when I am playing a vid.. like you said, its probably from the codec. But.. whats desktop composition
