Hey guys I'm experiencing a series of issues involving my windows 7 based system.

System:
Windows 7 Ultimate
Intel Core 2 Duo
4g ram
ATI radeon HD 5850
650W power supply

-My computer crashes at random times, particularly when I am either multi-tasking or playing world of warcraft. At first, I assumed it was my graphics card oveheating that was causing the problem, but seeing as having itunes and youtube open at the same time could also cause the crash, that may rule the graphics card out.

-Second, whenever I try to shut down my computer, all my hardware (mouse, keyboard, screen) turn off, but my case fans and motherboard fan continue to run. They are hooked up directly to the power supply yes, but I have never had this issue.

-When I put the computer into sleep mode, all the hardware once again turns off, but pressing my keyboard key only restarts the keyboard, the computer remains in a dead state. Note by the way that the motherboard and case fan are STILL running while in sleep mode.

I have no idea what can be causing these issues, they have only recently started up. I use to have dust issues before, but my computer is dust free at the moment. I ran speedfan and it seems that my processor temps are running up to the low 70's (celsius) while simply watching youtube videos.

I am contemplating getting a new case with better ventilation as this case has been nothing but a dust magnet and only has 2 fans.

THANK YOU if you took the time to read this and any feedback is appreciated, I apologize if this is the wrong subforum to post in, but it seemed the most appropriate for my mystery issues. Thanks again!

Are all of your drivers installed correctly with the latest versions? Could be any number of things. What do your temperatures look like in the BIOS?

well I don't know how to check them via the BIOS, but speedfan showed the processors to be anywhere from 40-70 degrees celcius, 70 being when I watch videos.
