Hey guys my computer turns off directly without any bsod etc when its left idle with games on .. it does happen when someone is using it too but it often happens when its left idle with demanding apps etc .. then it doesnt strt till i turn the switch off and on again and then it works normally again... i have noticed that when this happens,the led light on the motherboard is still on! I am really annoyed with this .. i am on the verge of buying a new psu but i want to make sure that its not something else coz i dont have a lot of money to do trial and error and keep buying a lot of stuff .. please help me out here .. I think its the psu coz my psu is of a shitty brand and its just 250w .. so i am guessing that it supplies less power for my pc but i have been running this pc for almost 2 years now on the same psu ..
Here are my specs
asus m5a78l-m lx v2
amd fx 6100
4gb transcend ram ddr3
nvidia geforce gt 610
500gb hdd
iball psu model PSY 255
Please help me out here guys

Best solution
You should buy a new PSU, when these types of things happen it is almost always a PSU problem or motherboard issue. One easy way to figure out if it is the motherboard or not is by hooking one of the case fans directly into the PSU rather than the motherboard fan headers. Then, when the computer shuts down unexpectedly on you, if the fan connected to the PSU is still running, then it is a motherboard issue. Otherwise it will be a PSU problem which is 90% likely.
I highly doubt it is a motherboard issue, your PSU is old and weak.

yes that is definitely a power supply issue, you should invest in a new one preferably around 500 watts with 80 plus efficiency 500 watts may be a little overkill, take a look at his GPU. If he plans on upgrading the GPU, 500 is reasonable but he should really go with 400 watts if he can from a good brand.

thanks for the prompt reply but the thing is that i have just got my psu replaced for a refurbished one, so i dont know how it can be the psu .. ill try connecting the case fan to the psu directly and see how it works out .. and if the light on the motherboard is still on even when the pc shuts off directly doesnt that indicate anything?

I think the problem might not be a PSU failure but that it has too low of a wattage to supply enough power to all your components during intensive tasks like gaming.

yes even i think that it may be that the psu is too low wattage coz i checked on the asus power supply calculator site and it says that my pc requires 450w

Yes you definitely need a new PSU, you should buy around a 450 watt. It simply cannot power your build with 250 watts of power, sorry.

it means 80% efficiency, eg if a power supply is 80% efficient if it draws 600w from the wall it would produce at least 480w for the system to use. hope that helps do also note that the psu would be 480 watts because thats how much it produces for the systemohhhh!!! so that means the psu that i have is 250 watts .. and assuming its a shitty brand psu it maybe drawing 70% maybe so it comes down to 175w
.. i guess i really need to upgrade my psu . thanks so much for the knowledge

Efficiency is how much energy is wasted as heat when a PSU is drawing from the wall.
If a PSU is trying to pull 2580W from the wall and it is 80% efficient, in order for the PSU to draw it's full 250 watts, the wall must be producing 300W in order to feed the PSU. So efficiency doesn't mean your PSU is putting out less than it's stated wattage, it means it requires more from the wall in order to produce its stated wattage.

Your GT 610's TDP is 29 Watts
Your CPUs TDP is 95 Watts
That is 124W. Add 50W for the rest of the system, that makes 174W. Add 100W for headroom, that puts you up to 274W. Your PSU is 250W. Technically is SHOULD be enough to power your system. The problem with older PSUs (and cheap PSUs) is that they don't put out their stated power. Even if the problem isn't the PSU, I'd recommend replacing it. Iball PSUs can be dangerous to your system.

I know it can be frustrating. It sometimes can be really difficult to find what the problem is with computers. Especially if you don't have another system beside you to swap parts in and out for testing.
It looks like a psu problem based on the quality of that psu and the fact that it is a few years old. That would be the first thing I would swap out and test. If you can't swap a different PSU into your system for testing, then I guess your only option is to buy a new one. The good news is, PSUs are not that expensive. What website to you like to shop from? I'll see if I can find a good deal on a quality unit you can trust.

flipkart
snapdeal
these are the two sites i usually shop from ... i found out that good quality power supplies are atleast around 2500 rupees and my budget does not eexceed 1000 rupees right now .. check if u can suggest me a good psu around 1000 rupees or i may have to wait a month or so
zebronics 450w
this looks like a good one as far as my budget and reviews are concerned plus it has a 120mm fan too .. do u think this one would be good?
heres a site for some more info on this one zebronics site

so i opened up my pc and apparently my casefan was already directly connected to the psu .. and turns out that it does shut off when my pc turns off unexpectedly .. is this enough evidence that its the psu itself and nothing else?
