can be a few issues. first one it could be over heating...cpu and ps have over heat shutdown built into them. i would open your pc up out side where you can blow the dust out with some canned air or air compressor. when done leave the side case off and check that the fans are moving..most time on old pc fan wear out..when they do they dont spin or spin slow. the other issue can be hardware based..as pc parts get old caps go bad..new mb dont use the same caps as older ones..vendors found out the caps used to dry out and fail within 3-5 years. the same issue goes with old power supply's. i would start by running memtest to see if your old ram is fine. if it passes i would run a quick run of prime95. when running prime 95 have hardware monitor program running it show you voltage of the power supply and temps..watch the power supply voltage if it drops below x volts your pc will reboot.

one more thing the time decreases everytime i restart my computer
for ex:if i run my computer and play games then it will shut down after half an hour, next time it will shut down even more quickly like 10 minutes and next time 10 minutes or 7 minutes

and if i run my computer after 12-15 hours then i can play games upto 2-3 hours the thing is that it needs rest like a human

it a heat issue that causing your error. as the pc been on it already warm then it shuts down quicker. the noise is the gpu or cpu fan running at full speed to cool your parts. i would start by opening both side panels and look to see if there a lot of dust inside the pc causing an over heat. if not check to see that the cpu fan is moving. i would then power the pc down..unplug it from the wall for safty. if it got the stock intel cooler with the plastic legs i would see if the legs are lock. the heat sink should not move. if it does you could have a broken heat sink. also check that no wires are in the cpu and gpu fans. i would then run prime95 and hardware monitor and watch the cpu temps....30-60c are fine..if it goes higher ie 70 or more then the cpu is going to lock up. with hardware monitor running try running a video game and see if the gpu temps clime...the gpu fan should ramp up with the heat...if the gpu has an issue it will keep ramping heat till it locks up.

if you think it the gpu see if a friend has a spare one..as long as it the same slot (agp/pci-e) you will be fine for testing.
