PC shuts down after 30-40 mins...

[vindance1]

^ that usually happens with cheap PSUs with limited 200v-240v input range , with low hold up time or bad primary cap ,

but AFAIK highly unlikely to happen with RM 750X though , ..

it supports wide input range from 100v-240v , so voltage anywhere in that range it should keep on working without tripping PC ,

and the hold up time with this 750 watt PSU is going to be very long with only around 100 watt max load of this current PC and even more if it's just idling...... he could probably switch off and on Main AC switch very rapidly manually and PC may still not restart/shutdown.. so minor fluctuations are highly unlikely to make this PC shutdown or restart as long as it is above 100v

also it would be good if both the topics are merged to maintain continuity and avoid scattering of replies in different threads

Duly noted sir. I have also ordered a new Gigabyte Motherboard which will arrive next week. Will keep you guys updated about the progress I make.

This community is really helpful for novice like me.... Thank you guys.

Please stop buying stuff before knowing the exact problem. People here are saying buy this, buy that. What you should actually do is check with someone else's motherboard or PSU. This might seem difficult but blindly buying stuff without knowing the issue is the biggest mistake you will ever make.

First try running your PC with a motherboard from a friend, or go to service center and request them to do it.

Man he spent 10k on a PSU, even though the PSU WASNT the issue. Someone should have warned OP regarding this. 10 years warranty is fine, but a component that isnt going to be used to its full potential, is not.

Why so serious?It is not your money.It is not like @op is wasting money on useless items,maybe PSU wasn't the issue but that doesn't mean one should not buy a good 10k psu after 4-5 years(@op's system is this much old) if one has the money.As for not using a component to its full potential,again people who have money don't buy Ferrari to drive it like Michael Schumacher at 300Kmph.

Hey your PSU looks old, upgrading to a better PSU would be great in the long run.

Hey your problem seems to be the PSU. Get a new PSU and your problem will be fixed.

Do you notice the difference? Its entirely possible the motherboard is not an issue as well. Are you going to say next - Hey the motherboard may not be an issue but that doesnt mean one shouldnt buy a good 10k motherboard after 4-5 years if one has the money.

@OP
First find out the exact problem OP, then buy what you need to. Dont blind purchase based on forum advice.

Obviously its your money, and you have a right to do what you desire.

There is something called "worth it or not". It is easy to give suggestions when you are not the one following it.You say "check everything" but do you also know whether it is "worth it" for @op to "check everything".

I live in a remote city and there are no PC repair shops (yes there are still places like this...). So I will have to do with limited knowledge I have, and purchase online.
Thank you.

Now it may be the case that @op has to make a trip by public transport/pvt vehicle to another city altogether resulting in spending of both time & money which he may not be able to afford then would you still suggest him to "find out exact problem" by carrying his system to a place dozens of km away with multiple trips & spending hours in transit+waiting for results not to mention all this for a 4-5 years old system.

This is hilarious lol.
I am not sure what was going in OP's head but looks like one or two people who commented in this thread had nothing!

Dear friends,

Wow it seems a debate is on..... Anyways I thank all of you for your suggestions and support. I repaired my PC yesterday and now it is working fine..

Now I believe I owe some answers to you all.

I had to purchase following components to get the job done.

PSU corsair's rmx 750 - Maybe my old PSU Antec 450 was fine, but I posted picture of it in forum and it turned out to be an OEM (don't know what that means..). I don't regret changing it because I plan to change my system after 4-5 years and want to reuse this component.

Gigabyte MB H81 m rs. 3780. This was the actual problem. I didn't spend much on this for above mentioned reason.

Actually it is very difficult for me to take my system for repair. I work 6 days a week 9 to 7 and Sunday many family obligations. It is much convenient to repair myself and trust me cheaper too...

My money is hard earned and I spent days before finalizing the products and purchase from correct and cheapest online option....

This forum is a boon for novice like me. Thanks to all.

1 more update... I accidentally broke the clips of CPU fan that attaches it to MB. So I cut all the 4 clips altogether with hexa blade and tightend it with 4 screws instead. I am impatient as well.....

I know all you guys will laugh at it.

Thank you all once again and belated Happy new year.

Interested to see this "thing" - mind sharing a pic or two if you get the time to do so ?

And how exactly would this solve his problem?
