Random? lockup

[Phaden]

About a week ago i started having random? lockups in PS. Not sure what its from but heres the details:

I have P4 2.8 HT 800 FSB Gigabyte 875P
512 of 2700 RAM
ATI Radeon 9600 Pro
Onboard sound
Cable modem w/ router.


I use Teamspeak in game. I have played PS for almost 3 months and never have had this type of thing happen. Basically i start up Teamspeak, then PS. Anywhere from 1-45 minutes later i lock up. It can lock 3+ times in 5 mins as well. No CTD, just locked with picture still on screen. Ctrl-alt-Del does nothing, Alt-F4 the same. The light for power is still on, but the red hard drive light doesnt do anything. It almost sounds likr the harddrive is not doin anything at all.

This doesnt happen to any other games i play. C&C generals, Battlefield 1942. I can play for hours and hours. I noticed that my brother didnt lock when he played PS so i started to wonder.

I noticed i only get the lock when i have Teamspeak running. So i tried playing without and over 3 hours no locks. So i started Teamspeak and left it on a blank desktop, and low and behold it locked the computer. I tried it with generals and it dd the same thing.

So im kinda sure its TS but it did lock once or twice in the described manor when TS was not on. I tried re-installing TS but it didnt help. ANy other suggestions as i REALLY like having TS and its a major part of our outfit.!!! Please reply with anything else you have to try or comments as i have NO IDEA.
