Couple days ago while playing a game my pc restarted it self and after that my graphic card is dead.No matter what I do I couldnt make it work just dead.

I have bought a new GTX 780 yesterday and plugged in.This time it begin to restart pc during games.I switched to other user in my windows and didnt see any kind of restart for 2 days but couple minutes ago again it restarted.

I have an old PSU which was 4 years old and its 750 watt can it be the problem is there any program to look at it ? ?

Is my cpu overheating ? ( I am checking the cpu temps often it doesnt seem it has a problem)

Motherboard causing problems ?

Software based problem ?

Too many electrical devices are connected to my room electrik connector can it cause problems like this ?

My Rig:I7,GTX 780,8 GB RAM,750 WATT PSU,1 TB

Except the PSU everything on my system is less than 6 months old.

I7 4770 K
MSI Military Class MSI MS 7823
ASUS GTX 780
Toughpower 750 watt
2x4 Kingston Ram
1 TB DISK

I didnt use any external cooler for my cpu because while buying my pc I didnt had money to spent on it but I am constantly checking cpu temps and they seem fine.

Also while using this rig 3 days ago my old GTX 480 died.

I think about four options.

1.Cpu overheating
2.Mainboard is not enough for GTX 780
3.Old PSU
4.Electrical connector or cable problem.

Sounds like time to check voltages and temps

Temp ( CPU/GPU)
Most likely PSU though what are your rail voltages esp. the 12V rail. but 3.3 and 5V would be good to know too.

EDIT: Double check your mobo and CPU one of those is wrong the mobo is a 1155 socket and the 4770 is an 1150 socket. Did you mean 3770?

Are you sure that is your motherboard?
I suggest you get HW Monitor to check temps:
www.cpuid.com/softwares/hwmonitor.html
Use asus gpu tweak to check gpu temps idle and when at load.
Make sure all your cables are secure.
Check if you updated all your drivers. GPU and motherboard.

Oh sorry I checked it via system information.

It's called MSI MS 7823 when I open up my pc it says Military Class.Is my graphic card and processor is too much for it?

http://ca.msi.com/pic/product/five_pictures4_2846_20130514183702.jpg

I also switched off unneccesery devices in my room and switched my power cable and tweaked max tempture settings of my cpu a couple minute ago I am going to test it out and see problem continues.

I7 4770 K 3,5 GHZ
MSI Military Class MSI MS 7823
ASUS GTX 780 3 GB 386 Bit
Toughpower 750 watt
2x4 GB Kingston Ram
1 TB DISK

As I said my old GTX 480 died couple days ago can it be the same problem which restarts the machine with new graphic card.

By the way I also download that program now I can see all details of my pc if the problem is in the voltages which part of this picture do I have to look how should I read details ?

I think it is mostly likely the power supply not supplying the correct voltage under load thus a restart.
Since it has been 4 years it might be better to look for a new PSU. 550 -650W is fine. Get at least 80+ bronze.

But the guy in store told me that if you going to switch your PSU again you have to buy another 750 watt or more cause your graphic card max watt is 600.

Was he just triying to sell me some other thing or telling the truth ?

So 600 watt is enough ?

What is 80+ bronze ?

If it is a PSU problem can it be the reason of the death of my old GTX 480 ?

You won't need a 600W power supply. He not really telling a lie because he doesn't understand or to sell, he looked at Nvidia's guideline which is overkill.
A decent 550w would be enough.
80+ bronze is a measure of efficiency when converting AC power from the wall to DC power for the hardware in your PC. It is now considered a measure of quality of a power supply but it is not the only one.
Video explanation : https://www.youtube.com/watch?v=dOXTZizoknc
Good brand to buy from is Antec, Coolermaster V series, Corsair (HX,AX or TX series), Seasonic or XFX

Your 12V rail is low likely it is dropping farther under load causing your restarts. probably what killed your 480. Follow Suztera's advice on getting a new one.

+1
yeah your +12 rails are lower than it should be. Do you have a budget for a new power supply.
I would recommend this but if you have more to spend, you can get a better one if you want:

So you are telling me that my 12+ values are lower than it should be.Just to let you know I took that photo during internet browsing no games were opened at that time.

Which value should it be ?

Edit here is my +12 volt graph during gaming(same game cause restarts) during normal pc usage (browsing internet video etc) it goes up and down between 12 - 11 but in all graphs during gaming its below 12 and its steady.

Is it normal for it to be steady like this ? Its not steady during normal usage only in games.What about your graphs and +12 values how are they ?

Sorry for asking again again guys but I really want to be sure I have already lost a good graphics card and spent huge amount of money to buy a new one (huge money according to my budget) and I only want to spend if its going to solve my problems.

Each rail should be at what ever voltage it says so 12 = 12 3.3 = 3.3 5=5 or pretty close.

ATX spec says 5% (less % is better a good PSU will be 11.9-12.1V) so 12V rail is 11.4 - 12.6 volts BUT more importantly it should NOT move. Your min max and current should all be almost identical. In your case you have a drop of 0.08 which is pretty large for a 12V rail that hasn't done anything at all yet.

I'm willing to bet that as your system starts to demand power that voltage will continue to drop (b/c PSU can't keep up) until your system is no longer stable thus it shuts down to protect itself.

I do not know about the recording though.

As you can see its stable when I open games but its always below 12 mostly at 11,88 V.

Also my 5+ and 3+ graphs are like this too they are not steady they keep going up and down.

Okay I can't say 100% since your PSU is being weird but the ripple on the 12V rail looks excessive to me (spec is 120milivolts or .12V MAX) That looks very close to the limit.

You have no temp problems everything there looks good.
Mem issues almost always either freeze the OS or BSOD
Software won't force a hard restart (so it is a hardware prob)
You have a pretty large volt drop for what should be a light load on a 750W
The PSU is 4 years old (they do age)
5 and 3 Volt rails also exhibit the same behavior
mobo/CPU likely to cause more and different problems if they were bad


Basically can't say 100% that your PSU is bad but in my opinion that is by far the most likely culprit.

Hmm oke than I will check my local store and see that if they are avalible if I can find enough money to buy it : (

In the mean time I am running bencmarks on my computer the 3D Mark went fine and my overall score is good.To be honest I have excpected a restart during the bencmark but it didnt happen.

My restarts always occur when I am playing the same game Wargame Red Dragon is a 2014 game not soo much heavy on graphics but I am sure its heavy on CPU can this game be the problem of the restart ?

Maybe overheating CPU my 4770k doesnt have extarnal cooler I use the one who comes in the box ?

At sock speeds the cooler is fine. If you OC though you should replace it with a better one.
