Computer restarts: power problem?

Dear, help, please - the trouble is with the computer, and I can not understand what.
I quote the letter to the warranty:
Last year, in June, I purchased a computer with the following configuration:

CPU Intel Core i7 - 2600K
motherboard Gigabyte GA-P67A-UD3P-B3
video Radeon HD 6990 Gigabyte PCI-E 4096Mb
drives 80Gb SSD Intel 320 Series / 2Tb SATA-III Seagate Barracuda Green
RAM 4Gb DDR-III 1333MHz Kingston
cooler Scythe Ninja 3
case Cooler Master HAF 922M
PSU 900W FSP Everest

Almost immediately, problems arose in his work:

A mechanical creak is heard, most likely bearings.
During the peak load on the video card (“heavy” scenes in games with top graphics at maximum settings), the computer spontaneously rebooted.

There were no attempts to overclock the processor. Overclocking the video card (using the switch on it and AMD Overdrive) did not affect the appearance of the problem: it arose both with it and without it. It was also not possible to understand whether the appearance of the problem depends on the temperature in the room - most likely not.
Recently the problem has worsened:

Spontaneous reboots also occur under less “heavy” loads: for example, regularly when playing “World of Tanks” with maximum graphics settings. Moreover, sometimes the computer restarts shortly after the start of the game, and sometimes it works without problems for up to 30–45 minutes.
After such a reboot, the system occasionally reboots again at the POST screen stage.
The operating system takes a very long time to load: 2–3 minutes the logo “hangs” on the screen. At the same time, there are no “brakes” when working in the OS.

Installing the latest drivers for the graphics card and the latest BIOS did not resolve the issue. Nowhere, except in games, this problem does not manifest itself. BSOD dump after crashes does not appear. The computer is running Windows 7 x64 Ultimate (on SSD) with the latest updates, here are the results of the 5-minute Aida stress test , here is the CPUID data . Checking disks showed 100% "health". There are no significant voltage drops in the network, in addition, the computer is connected through a surge protector. The computer is vacuumed from the inside.
An independent search for a possible cause of the problem suggested a possible malfunction of the power supply - it may not give out nameplate power. There is also an option with problems in the motherboard or video card. A friend of mine solved a similar problem on his computer with an Asus motherboard by disabling "intelligent" power management in the BIOS. I didn't find such an option.
The question, in fact, is this: what could be the problem and how to track it?

The 2600K thing is not very hot, and the cooler seems to be good, the case is ventilated - but I would ask for temperature measurements under load in the studio in order to unequivocally determine the possible overheating.

Test the graphics card with FurMark

I will share my experience. There was a computer, a home server, I worked around the clock in a closet. Then he stopped being useful to me and I gave it to a friend. He added the necessary video card and made a gaming computer out of it. But almost immediately the computer began to reboot during the games. Sometimes immediately, sometimes it took several tens of minutes. It was strange, because The computer had been working for me for years before and I knew for sure that the problem could not be in it. In the end, it turned out that there was simply not enough food at home. Those. a friend lives in a private house, only a kilowatt comes to the house, the computer ate most of it during the load and the power was simply cut down. Do you have UPS?

Well then, probably "here he is - a bad tooth" ...

I have a very similar problem. It turned out that when connecting the second hard drive, they used power cables linked from the video card. I powered the hard drives and the video card with different cords directly from the power supply and checked the connectors, the problem disappeared.

Something your video card causes suspicion, 4GB of memory), throw off the bios, and remove the battery. and check for viruses that are written to the boot sector.

You have a good video card. The truth consumes up to 375 watts and the minimum required PSU power is 750 watts, and you have a 900 watt PSU. An absolutely similar problem recently arose with a neighbor after buying a new video card with high power consumption, he decided to buy a new power supply unit of greater power.

I started having similar symptoms a year after buying a computer, periodic overloads in certain programs, freezing of some memory tests. With the help of the aida64 program, I brought out graphics of the power supply of the motherboard, on which the standard oscillation of the 3.3V bus under load became visible. Replacing the power supply solved the problem

Auto reboot on BSOD is disabled.
I ran a 10-minute AIDA Stress Test (percent and vidyukha):
temperature
, fan speed,
voltage
, power supply
statistics

Drive the computer on the built-in vidyaha to localize the problem.

On P67 there is no possibility to use the built-in video

Op-pa! Ran FurMark with default settings .
On the BURN-IN test, I passed out immediately. On Benchmark with preset 720 - getting to about half the test and half the way from the initial to the maximum temperature.

Mystic ((
I explicitly reset the AMD Overdrive settings in the Catalyst Control Center (I don’t understand why they were enabled after reinstalling the system and updating the drivers, but oh well). After that, the BURN-IN test went with a bang: it reached 90 °, and then the coolers weren't allowed in - and the Benchmark 720 passed out again, even faster than before.

Try to measure the temperature of the GPU when the tanks are running? - Aida or CPUID HW monitor

I tried ... 78 ° temperature, it's okay, and suddenly it cuts out again ((
