Neither of you say what computer and operating system you're running which is unfortunate. Either way - are either of you using onboard graphics versus a separate graphics card? PT doesn't like onboard graphics. How much ram do you have in your computer? Onboard graphics typically steal the ram they use from system ram and if you're short on that or ram is going bad then you'll have issues. Have either of you deleted any fonts from the system?
