need help with game crashes

**my specs are in my sig**

recently i installed call of duty 2 and ghost recon on my laptop. both games keep crashing and i cant diagnose what the problem is. i also have Notebook Hardware Control installed.my cpu idles at 60 degrees by thats just doing nothing! but after playing games it goes way above 70 or even more than 80. it crashes somewhere around 5-15 min. into the game. when i say crash i mean it hangs and basically it gets stuck, so i have to force restart the thing.

there are two types of crashe that i experience:
1. blue screen w/ "hardware failure. contact hardware vendor for help. parity check/ ?????? (forgot this one).system halted.

2. the game just hangs and sound seems to buzz like it keep repeating itself thoroughly.

i currently have ATI CCC 7.1 on my laptop. i even tried installing the latest one which is 7.6. but still i get the same result. so i just rolled back to 7.1.

im really running out of options on this one. i bought a notebook cooler from newegg which is the "spire pacific breeze" it has yet to come around the 11th or 12th.

i really need help. also, i dont know the temp. of my GPU since i dont know any programs that can handle that.

 

Do you think you might be hitting your CPU shutdown temperature while gaming? Look in NHC to see what you have your shutdown temp. set to. Are you overclocking your GPU or undervolting your CPU? This can also cause system instability.

 

no overclocking or whatsoever.my clock runs at 400/450 and i think thats the default since i havent tweaked those. my cpu shutdown is set at 95 degrees. and the warning is at 85 (under ACPI tab).also, the ACPI box is checked but i cant seem to click the"show ACPI system control details" and it also says, "ACPI control system is not yet configurated for this system.

what could be the problem?? i play LOTR BFME part1 and call of duty(part 1) and it seems to be doing fine. i guess the system crashes only at GPU intensive games.

 

Mine says the same thing. Could it be because we don't have the professional edition of NHC?

 

probably but thats the least of my worries right now. jusdt checked again to see if the same thing occurs and it does. just 15 min into the game cpu reaches 69 degrees but if i press alt+tab which sends me to my desktop it drastically cools down by a rate of 1 degree every 4 second. dammit. whats wrong with this thing?!

 

anyone i really need help with this...
