Windows 7: Pc not working after intense gaming

Pc not working after intense gaming

Hello, i'm CrazyKilla

I was playing far cry 3 which my pc found hard to play until i enabled SLI which then boosted fps and i turned graphics up to verry high and started playing, it ran really smoothly until a few minutes later my pc turned off, straight away i unplugged power cables and turned off power supply, the power cable was pritey hot, i unplugged everything and opened pc up and getting burn smells, mostly coming from power supply, i immedietly pulled out many parts such as graphics cards, processor, and power supply which all were verry hot (but not the processor) the power supply was giving off a burning smell so i opened it up and didn't find any damage (probably because i didn't check well), i left all parts to cool off and put everything back as it was, my pc is getting power (LED lights, reset buttons, speakers) but when i turn it on nothing happens at all, im really worried... My rig is pritey expensive (about 1000) and i don't want to get damaged parts ): Also my power supply (i think) was given to me by some foreign pc technitians when i had problems but it could be my friend that gave it to me,


I have many fans (1 large at the front, 2 medium fans on the side and back, 1 small on processor and 3 mini ones on gpus and MB) What caused this problem and how can i fix this?

I can only assume that you are looking for confirmation on what you know is the problem:
The power supply is dead.

Everything you describe points to this. Burnt smells coming from any component is never a good thing, but a power supply is the worst.

Do not connect or use that power supply in your system. It could damage your other components. Get a new supply, one with sufficient power (and overhead) to run 2 video cards and the rest of your system.
How to Pick the Right Power Supply

My advice is always to not skimp on the power supply. It is the most important component in the system.

I'm not sure that the brands and models available here in the US are available in Lithuania, so it is best to do your own shopping.

Personally I recommend Seasonic and Corsair power supplies. Some Corsairs are made by Seasonic, but not all. There is a link "who makes your power supply" in that thread I posted above where you can find that stuff out.

You will use a ATX 12v/EPS 12v supply for your machine. Make sure it has an 8-pin connector for your processor.

As to size of supply (watts) I use this calculator:
eXtreme Power Supply Calculator
Fill in ALL of your specs.

Most important is that last box: "Capacitor Aging". I always use 50%. That is because a power supply's output drops over time due to capacitor aging. It is common to reach 50% aging in 4 to 5 years. Heavy users can do half that. Buying a larger supply compensates for this known aging and extends the life of the supply.

If you are buying online look at the reviews. They will tell the tale.

This is a good supply to start with:
Newegg.com - CORSAIR Enthusiast Series TX850 V2 850W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply
Make note of the specs and compare them to anything else you are looking at.

I can assure you that more opinions and advice from other knowledgeable folks will follow. Everyone's needs and wants are different. It is all good.

The power supply you showed me fits my requirements, by the way i live in the UK but i was born in LT, my old power supply was 700 watts. I need to know what caused this? Was it over heating? Did power supply just fail or is 700 watt not enough?

EDIT: I found a epic corsair gaming PSU: http://www.amazon.co.uk/Corsair-CMPS...716764&sr=1-14

Never open a power supply unless you discharge the capacitors first. Or just never anyway if you don't absolutely know what you are doing.

Electrocution by power supply.

"Stuff Happens"!
When power supplies get old the components in it can dry out, overheat, and fail in slow motion. It is a buildup to total failure. How old was that supply?

External sources could be poor power (dirty power) going into the supply from the wall (power supplies compensate for this but not forever). And it could be just running it hard. The longer a power supply has to put out near full power the faster it will age just due to cooking in the heat.

Use that calculator to determine your total draw at high load and tell us what you get.

My PSU was slightly over 6 - 8 months old, i have my pc on 6+ hours on work days and 12+ on weekends,

Should i clean my PSU out every month or so? (If i do discharge those capacitors of yours)

Life is so boring without pcs and internet! Is it not?

Much too young to die. I might suspect a defective or cheaply made unit.

Yes, you should clean everything in the case, including the power supply, relatively often. Once a month may be good if you have dusty conditions. Use compressed air to blow the dust and hair out. There is no need to disassemble, remove, or take apart anything, just blow it out. They sell cans of compressed air just for this purpose.

As TVeblen says don't open or take apart the PSU; just use compressed air in the entire inside of your computer to blow away dust, etc. Your computer will thank you with lower temps.
