Windows 7: windows 7 64bit random restarts at idle (BSOD)

It seems i had this problem since i got this laptop. The computer just randomly restarts. sometimes it reports a blue screen error; sometimes it just totally freezes; most of the time it will auto reboots without showing the physic memory dump screen and then report as " the computer have recovered from an unexpected shutting down".
first, i thought it was the anti-virus tools problem, so i uninstalled norton and installed Kaspersky, it didn't work well. these problems still happens now and then.

After looking up in the forum, i found some helpful resources. someone says it might be connected with my hard drive partition, or a matter of the name of these drivers. i did the partition using the windows 7 default partition tool, not really sure if it is the issue;
Someone mentions the CPU overclock issue, not sure what it is. but i did do some optimization. I bought this notebook a month ago, so its quite new.
As i heard most of this problem occurs under a windows 7 64 bits system, does is matter?

, i could not stand this anymore, as a college, i couldn't imagine everything that i just work on has lost without saving. Please help me!!~

Did you get rid of Norton properly?

Hi, Welcome to SF,

Could you post us the Dump file so we found find what would be the exact problem

Thanks,

i am working on it. hopefully it will work. thank you so much

yes, i got rid of it using "program and features" in control panel.

After analyzing the crash, it shows that its my HARDWARE's problem, and reprots a ": WHEA_UNCORRECTABLE_ERROR" error, what should i do next?> which part of hardware should i fix?

i tried before, but it says i don't have the permission, even though i am the administrator, i don't get it. However, the micro debugging tool detects it as a hardware problem, do you have any suggestions?

WHEA_UNCORRECTABLE_ERROR is a STOP 0x124 error. It is a hardware error - usually caused by failing hardware or incompatible hardware/programs/drivers.

So, as it's a laptop, you can't have installed much of anything in the way of hardware (if you did, please tell us).
So, it's gotta be either failing hardware or an incompatible driver. What sort of optimizations did you do? What programs have you installed?

Please provide us with this information:

i believe it is the hardware that causes the issue. Will optimization leads to hardware fall? if so, should i replace it?
