Hello,I need help with my computer.
I have just installed windows 8 32-bit (prev. I had windows 7 and I installed it normaly just to save files in windowsold folder), when the installation was finished I installled my video card driver and direct-x (the last one at microsoft web site), the fact is when I play any game I can play It only for 10min or 15min max at that time my comp screen freezes and close the program automaticly. Im playing games like Dota 2 and Far Cry 3 but in medium quality Its pretty compatible to play (60 frames at any time), I just dont know what to do to stop the crashing "freezing screen" myb I just forgot something to install (but what?)
Im coputer components:
Processor: AMD Athlon (tm) 64x2 dual core processsor 5000+, 2.8ghz
Memory:4gig
Direct-x version: directX 11
video card:
name: Ati Radeon HD 5450
aprox total memory: 1784MB
druver model: WDDM 1.2
PS: when I runned this games on my old op-sys (windows 7 - 64 bit) it runned perfectly (I have installed it too).
Ty for any answer.
 
Solution
could be your PSU is close to shot causing errors as it gets taxed or your GPU or cpu could be over heating (get a hardware monitor and check temps)
