punkbuster working in background?, pc lag/freeze Options

[m33amkii]

hi guys, i wonder whether or not any of you have expeienced this before? :

playing on the server, suddenly the game freezes (and the sound etc) and the HDD LED lights up (HDD in use) and screen stays frozen for a few seconds. in the meantime, i get owned by magik5 or some other tramp , and i 'wake up' to the 'critically wounded' screen (cos of course, everyone-else's game has kept going)

this does not happen just once, but a few times in succession, for about 5-8 seconds each time.

i wonder whether it is PB trying to take a SS of me, and re-trying every time due to lack of success or something. i have no other background programs running, except vista windows updater or whatever and kaspersky I/S.

running vista x64 home premium, and lates punkbuster outfit

also poor k/d ratio when this happens , making me look like a dick

any suggestions?
