Check temperatures. Speedfan or something like MSI Afterburner'll give you readouts. My guess is that for some reason you're overheating badly.

i really dont know how to check it but i am working in an environment where 18 degrees is maintained . shud i get it checked by service centre

Get one of the two applications I've mentioned above.

http://event.msi.com/vga/afterburner/download.htm
Speedfan's probably a little easier to use.
Do one of the things that makes it crash while watching the GPU temperature in either application. If it goes over 75C, it's probably the cause of the crash. Check the CPU temperature as well: if it's over 65 or 70, it could also be the culprit.
It's nice that the ambient temperature is so low, but that doesn't rule out an overheating processor or GPU.

Thanks friend i have downloaded and i am really amazed that the core temperature are soaring to 72 degree. please tell me what to do?
HD0=48C
Core0=72C
Core1= 69C

Ah. There's your problem. It's probably clogged with dust; see if you can unscrew any bits and find the clog. You may be able to remove quite a bit at the input/exhaust ports with tweezers, less invasively.

thanks, today i took it to a service centre and the fan was the problem creator. so replaced the new fan and now the temperature is not going beyond 59. thanks for your guidance.
