Answer #1
how much space do you have on your PC?
can you install anything else smaller? it could be related to the game.
do you get an error message?
Is the game 64 bit ready?
Answer #2
yes i can install smaller apps,i have enough free space,and the last games i tried were Assassins Creed Chronicles China and State of Decay Year One Survival Edition.
After i hit install after a few seconds screen freezes even ctrl + alt + delete wont work.
Answer #3
Check the log for errors and minidumps if there are any.
Answer #4
Run Intelburn test, might be that your CPU or ram is dying and can’t handle max usage
Answer #5
tried and says cpu is fully stable
Answer #6
make sure to have latest windows updates and gfx driver before we continue with solving the issue.
Answer #7
i always keep my pc updated,somehow im hearing fans are runing above normal,can it be that cpu/gpu is not getting cooled enough?
Answer #8
get aida32 installed or any other program that can monitor temps and you can provide an answer to that question.
hwmonitor / aida32 / everest / speedfan
Answer #9
Can these games be installed on another PC? If so, then you can look at your PC, something is not up to date, video wise perhaps. Over heating perhaps, but since it fails on the install and everything works correctly, I assume, its seems to be a compatibility issue with the games and your set up. Thats why you need to try a different PC, or one of a friends PC.
Answer #10
