My pc randomly restarts randomly. I don't know why but whenever my pc is restarting I notice that my ram and GPU are very hot

Windows 8.1
4 GB ram
Dual core Intel CPU
Nvedia gforce 710 graphics card

Plz help getting headache and tension and stress due to this
Sounds like you have an airflow issue internal to the computer case. Run it with the cover off and see if this helps avoid the thermal problem. A case with inadequate airflow can create hot air pockets inside and this can lead to thermal problems.

Video Cards do get warm/hot, but RAM should be just barely noticeable warm. If RAM feels hot enough to cook and egg on then you might have a power supply that is feeding the RAM a higher than normal voltage causing the RAM to roast, Additionally if you have any overclocking going on of the GPU ( if the 710 allows overclocking via software which I am unsure of for that card ), or you have in BIOS it set to overclock the RAM, undo all overclocking and run it at normal clocks and see if that helps.

If its an airflow issue in the case your solution is to either run it with the cover off which is the free solution, or spend money getting  an extra fan or two mounted inside to generate more airflow of cool air from outside of the case and more to exit, or install the guts into a better case.

*Note:  Airflow DIRECTION of the FANS should be checked to make sure you dont have 2 fans drawing air from outside into the case, but none set to exit. The muffin fans usually have 2 arrows on them. The first arrow showing direction of fan blade rotation and the other showing air direction when running.I do run the PC without the cover. I don't remember overclocking my GPU and it only restarts when I play video games
During Idle the temperatures are at followsPretty hot for idle...leave speedfan runnin in the tray then copy/paste results after 4 minutes gaming.Thermal compound on CPU might have dried up making a weak thermal bond and 25 degrees hotter than it should be when idle. The CPU should thermal throttle when it roasts in the 80C+ range which would lag out the performance.

I agree with Patio in running a speedfan graph log for TEMPS and then play game and see how hot the CPU and GPU get. Hopefully you can see how hot it gets before restart.

*If you removed the CPU heatsink and then placed it back onto the CPU without new thermal compound it will run hot idle like this too. Have you ever removed the CPU heatsink and PUT it back on without new thermal compound ADDED and old removed first?No I did not even touch the heatsink.
I have a doubt if it is a thermal paste problem why is my you so hot .
When  I was checking the bios there is a power section in which 3.3 voltage was running at 2.8
My psu,monitor,speakers are connected to the same socketHi I am back the pc still restarts after everything now it is a black screen which shows nothing when I boot it up not even the bios plz help I am getting a big headacheIs this the same PC as the 1 with mis-matched RAM ? ?NoSee Here...
