Hey guys, I'm sure I saw this subject posted somewhere here recently, but couldn't find it when i ran a search, so if you know of the thread, please let me know, apologies.

My mates computer, an athlon xp 1600, 512mb ddr, maxtor 40gb, netgear lan, etc, epox 8kha+, ati radeon 9600xt, creative sb audigy de, etc, has a problem with XP. Every so often, say, once an hour, the computer completely locks up, for about 10 seconds, and then regains control. Normally I wouldn't think much of it, but this happens when no apps are open except for media player, and stops the playback completely. Checked out some of the processes on google, and they're all legit, although a couple of utils for his DSL modem look kinda suss (mainly coz i never seen them before). I'll list a few here. Any help would be greatly appreciated, thanks guys.

ati2evxx.exe (ati util?)
ati2evxx.exe (again!)
atiptaxx.exe
dslagent.exe (dsl modem)
gsicon.exe (dsl sys tray icon)
