CRASH/BLACK SCREEN/CPU KEEPS RUNNING

So....a while back I wrote about this problem and it was somewhat solved so I went along with it until now....I had to uninstall everything base game (store bought) and stuff packs (from here)...re-installed diesel, season, town life, master suite, generations and ambitions and now i added University Life. I updated to 1.55 and did the ultimate fix plus the DEP solution and compatibility since I have Windows 8 and still in mid-game it crashes. If i start out a new sim everything works fine until he's aged idk 20+ days and then its starts messing up


I have no CC or mods

I have a HP Envy h9-1315t Phoenix desktop, 
windows 8, 
Intel core i7-3770, 
64-bit OS,
AMD radeon hd 7670 1GB, 
2T hard drive
& cooling system

Please make sure your game runs with your AMT card, your Intel card does not support the game.

And how do I do that??

You should have an AMT icon in the toolbar, right?
I'm not so sure... I used to do that on my old laptop, but I couldn't tell you the steps by heart...
Do you want me to try through Team Viewer?

Well I found the control center for the video card called catalyst and i found the gaming performance section and just clicked high performance for everything anti-aliasing && 3D settings...cuz i read somewhere if you jack them all up then your comp switches to the game card :/ dunno if that will work but Ima try an see

Cool! Tell us the result!

It crashed again within an hour of gameplay...
