Computer Help - Graphics Problem

[Honeo]

*If this is in the wrong place please move, it might be.*

So I'm having some computer troubles... I can start up my computer, browse web pages, all that good jazz. But every time I try to watch youtube videos, load animations, play computer games (Diablo III, etc.), or even go to some websites, they all crash. For websites, the screen will go black. Flash and java games will mess up and stop working, eventually going black. I can get to the Diablo III log-in screen, but when I try to sign in the game crashes with an error.

I suspect it's a graphics problem? I'm not too computer savvy so I'm not really sure. I've tried updating my drivers for my graphics card with no luck fixing the problem. Any other suggestions?

Computer Specs (basics):
Intel Core i7 CPU 870 @2.93 GHz
8 gig ram
64-bit Operating system
ATI Radeon HD 5450 Graphics Card

If you need anything else, I can provide it.

Thanks!

Sounds like Flash and Java could possibly be causing. Have you tried reinstalling/updating them both? Also, what browser do you use?

Same thing has been happening on Google Chrome and FireFox. I tried both.

Would that explain Diablo III not working though?

Does diablo 3 utilise flash?

Maybe even update direct x, if that's what diablo 3 runs.

Just tried that, no such luck.

Could you post the errors outprinting?

Try rerolling drivers to a slightly older one then the most recent, also check temperatures(Speedfan should do the job). And post said results back on here.
