Hi, i have a problem that is driving me crazy.

For a few months now i cant play games for more than 10-15 min.

Example, im playing cod 2 multiplayer, battlefield 4, assassins creed and suddenly my monitor goes blackscreen, sound goes sometimes zzzzzz, the keyboard si frozen, i can still hear my friends on skype, teamspeak....
Now i have to turn off my power supply and wait a few seconds then i turn it back on and start the pc, if i just reset my computer it wont start the screen will still be black. I have test everything and nothing seems to be wrong but i dont believe that, something must be wrong. The temperatures are all normal. I ve done clean format a few times. Im running on win 7 x64

My specs:
Intel i7 920 - 2.66 GHZ, 1366
ASRock X58 EXTREME6 LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Seagate ST31000528AS 1TB hard drive
G.SKILL 2GB DDR3 - 1600, 6 GBPI x 3 RAM
Nvidia GeForce 295 gtx graphic card
Thermaltake Qfan 750 W toughpower power suply

thx

:welcome: siimee

You have said that temps are not a problem but what you describe is typical of an overheating issue, this includes the PSU itself, the GPU, Ram, CPU and even the HDD.

Do some gaming and then run Speedfan, take a screenshot and attach it to your next reply for us, can you also tell us how much free storage space is available on the HDD and how many case cooling fans you have.

Download Speedfan and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

(this is a screenshot from a vista machine)

To capture and post a screenshot;
Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.

Depending on the results we may need to run further software for comparison http://www.cpuid.com.../hwmonitor.html

Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

i have hdd 1 TB and 861 gb si free and 2 fans 120 mm.

Yesterday i was trying RAM one by one and with the third ram i was able to play 1hour and a half, today i go playing and it blackscreens again after maybe 15 min.

A few months ago i broke processor socket(i ve bend the pins) so i had to buy new motherboard. Did maybe the old board did some damage to hardware cos of that...

A couple of your temp readings are too high for a computer that is not under load as is the +12V rail which may be causing it, please run HWMonitor and again post a screenshot for us so that we have a comparison to Speedfan and check out the attachment below which shows what your PSU readings should be.

You also have high CPU usage for an idle computer.

Some of the voltage readings are missing, can you restart the computer and check them in the BIOS, no screenshot is required just make a note of the +3.3V, +5V and the +12V rails and let us know what they are please.

Just spotted your previous edit, I could be wrong but I cannot see why any other harm could have been done by the previous mishap.

+3,3 V = 3.248 V
+5 V = 5.400 V
+12 V = 12.830 V

As per the table in my reply #4, your +12V rail is putting out too much and is effectively cooking your hardware and may have already damaged one or more components, time to swap in a known good PSU that has adequate wattage and amperage, I would however have the present one professionally tested first if it is not under warranty, if covered by a warranty return it.

Again keep in mind that the PSU is not under load when you are in the BIOS, once you start gaming or watching videos that high reading will increase.

A bad PSU is just that, bad and needs to be replaced, try and borrow a suitable PSU to test in your computer or have your PSU tested by a qualified tech who has the correct equipment.

Were you using the same PSU when the ati vapor x 5850.

Your PSU is putting out 12.830 V when the safety margin is 12.600 V and that is when your computer is doing absolutely nothing, some tech stores will test your PSU for free but do check with them first.

I was using the PSU. Ok so let me get this straight, my PSU is bad and for that is putting out too much and my PC freezes. I have to buy another PSU and problem will be solved as long as the other hardware is good.

Extra voltage = extra heat and voltage spikes.

I have to buy another PSU and problem will be solved as long as the other hardware is good.

I suggested the following in my previous reply so as to try and avoid any cash being spent while troubleshooting;

try and borrow a suitable PSU to test in your computer or have your PSU tested by a qualified tech who has the correct equipment.

The above are the only two ways to either rule the PSU out 100% as the cause of this or to prove that it is 100% the cause of it.

Just a FYI as to how a PSU is properly tested;
What the equipment does is simulate a computer under load and so the PSU behaves as it would when it is powering your PC, multi-meters and the basic testing devices that you can purchase from some merchants only test the basic voltage output from the PSU rails and so cannot be relied on as 100% conclusive.

Would it be possible to return the PSU that you have acquired.

From your reply #3

Yesterday i was trying RAM one by one and with the third ram i was able to play 1hour and a half, today i go playing and it blackscreens again after maybe 15 min.

Does this mean that the computer worked fine with only the third stick of Ram in it but it then began having problems when the other sticks of Ram were put back in the slots.

Has the computer ever been overclocked or any attempt at O/Cing been made.
