Recently I have randomly ctd

[Chass]

Hi all

my computer is really bad but I've been playing DaiZy for several years without problems.

Recently I have randomly ctd.

I think it is heating the CPU or the graphics card. Here, where I live has started getting hot, summer is near.

I recently change the processor of a 2.8MHz to 3.2MHz and began the CTD. I again put the 2.8 but CTD continue

I changed the CPU fan and I've also put an additional rear fan graphics card but still CTD.

I tested also Iron Front: Liberation 1944 and also gives me CTD but All other games work fine without problems. only Arma2 OA Dayz and Iron Front: Liberation 1944 crash to desktop.

I have looked at many forums but I can not find the solution.

I have installed and reinstalled the game but still the same CTD at 10 min, 20 min or 30 min. crash

Before playing 3-4 hours without problems.

it could be anything...could be a Betapach or wrong BattlEye? Any suggestions?..I can not buy another computer
