PR keeps crashin while loading the second map

Hello everyone.
On the off chance I have time for more than one game, PR crashes when I load the second map (but only when the previous round lasts more than an hour). It happens about halfway during loading. Every time. I searched in the forums and on the internet in general and did not find a solution that worked. I re-installed it, tried numerous other solutions, even changing binaries following a tutorial someone posted for Vista.
My specs are:
OS: Win7 32
CPU: Intel core duo e8200 2.66 ghz
RAM: 3 GB
Graphics card: Radeon hd 5450 1gb ddr3

I suspect you need to turn down your texture settings, alternatively lighting or terrain might help

Will try that, thank you.
