pc restarting randomly while playing dota 2

[saksham0161]

whenever i play dota 2, after few mins (almost 10 mins) my pc automatically shut downs without BSOD.
i dobted it has something to do with my GPU since my monitor first goest black then cpu restarts so i logged my GPU with digital sensors the log file is attached here below it contains the logs just before last restart while game play.why is it happening? i am able to play other games normally without any problem
here are specs of my computer
processor:intel core 2 duo process e7500@2.93 GHz
GPU: AMD 7730 1GB GDDR5
RAM:2Gb
OS: windows 7 64bit
update: i uploaded CPU core temprature log as well

whats your cpu and psu doing at this time do you know?
i would generally blame a psu for this sort of issue.

whats wrong with my PSU?
and why my PSU is failing only when i am playing DotA 2 and not with other Games

Dota 2 is CPU bound instead of GPU as is normal. Check CPU overheatings and stuff like that.

can you suggest me how to check CPU overheating are there sensors available for that too?

Real temp. is what I use. I would play for 7-8 mins and x out it will tell you your max and current temps reached. Is your heat sink clogged with dust?

i dont have extra heat sink. my GPU has only its preinstalled fan if you want to see my GPU temparature while playing DotA 2 take a look at the log file i attached

i will be posting cpu temparature soon GPU temparature with other details are in the log file

i like to use OCCT and set it to psu test.
you can see everything as it happens and it uses cpu and the gpu too which is a good way to test those 3 things (psu, gpu, cpu)
it will also make a folder full of little graphs for you so you can check them after wards.
looks like this..

i will try it out as well

here is the second log file(Screenshot check above) which shows cpu temparature before shut down also this time during reboot i got beep sounds also the pic contains the data of only last few mins before the computer restarted

i got this software but how to log graphs and tables from it continuously

it does it auto magically. it will finish the graphs when test is done.

Sorry. I just assumed you would know I was refering to the CPU heat sink. My bad. It just sounds to me like overheating of the proc is all not the card.
checking temps is where I would start. If you are reaching your max for the cpu then it will auto shutdown. My pc only looses it's signal to monitor when my card heats past its happy zone. Otr if my oc is not stable, thats why it leads to believe you are passing your heat max on cpu after 10 mins of play on such a cpu "intence" game.
Re apply thermal paste and or clearing out dust bunnies in the cpu heatsink is my first step. If not that then reset bios to default settings if you have overclocked and check case for good air flow.

if you not sure how hot its, just run dota again and when it shutting down just touch the heatsink, is that hot enough

 

[saksham0161]

i will post the test results soon

i have not overclocked my cpu its running on base clock and there is good air flow.. are the tempratures shown in log file before the shutdown outside the happy zone?

i have posted the tempratures in the log file attached above

 

[Shambles1980]

were you able to run occt for the full test and if not what were the temps like before it shut down?
