Something Goes Wrong

Hello everyone ,

From past few days I don't know what is happening with my old PC.
when I play any game or when I run 3-4 application at a same time on my machine suddenly monitor goes off and it shows no signal and PC get stuck(Hang) , I don't have any other option except restarting it. but the same thing happening again and again.
I am using this machine from past 5 years but i never had this kind of problem.
I have cleaned CPU , removed everything , cleaned and tried again but still the same.
what kind of problem is this ???
its really very sad for me cause I cannot play single game on it.

suggestions please.....

Have you tried re-installing the OS also??

but i dont think there will be problem in os. cause its working really fine.....
but if ur saying i will try that also.... will let you know

maybe a PSU issue or could be that the unit has now given up. 5yr old PC, are you seriously playing games on it?

something is wrong with Video Output. check that blue pin behind your cabinet it might be losen up time to time.
so next time happen this just push the monitor cable which is mostly blue in color. or power cable of your monitor.

if this doesn't solve it then RAM problem. that your slot might be stop working when motherboard heat up. just assuming here.

yes i play cs and dota and dota 2 using lan !!!! mostly i used for internet and downloading stuff

those aren't really heavy games. What is the Brand of your Power Supply?

Antec PP300V Power Supply

There might still be dust/dirt/cobwebs between the CPU fan and the heat-sink. Another possibility is that the capacitors may have worn out on your motherboard, check if any are swollen (around the CPU).

What are the tems at loads ??
