Hello everyone!
This is my first time here (asking the community at least), and so, this is my first time with a problem I couldn't solve with the previous questions/answers in the forum...

Basically, this is the problem: in some games (maybe all of them, but it takes more or less time depending on the game) my computer freezes after playing 15min-30min. The freeze makes the sound loop (like 1/8th of the music that was playing before freezing) and nothing from the keyboard (not even caps lock etc) works. Even the reset button from the case doesn't work, so I'm forced to hard reset this by holding the power button from the case and wait for it to shut down.

First things first, this is a brand new system, specs:
CPU: i7 Haswell 4770 3.4Ghz-3.9Ghz (for now, stock cooler)
Video: No card, using integrated Intel HD 4600
RAM: Corsair Vengeance Pro 1600Mhz 2x4Gb
PSU: NZXT Hale82 750W Modular (doesn't support c6/c7 states, disabled in bios anyway)
HDD: WD BLACK 1TB
MB: Motherboard ASUS MAXIMUS VI HERO
Case: NZXT Phantom FULL TOWER USB 3.0 Edition
OS: Windows 7 x64 Professional
Other: 23" LED 1920x1080 59-60Hz, all drivers+mb bios updated

Obviously, I'm not overclocking or forcing my system in any way. I've chosen the 4770 rather than 4770K because of the virtualization and the TSX set instructions.

The first thing I've checked was temperature: gaming made the core temps (measuring with msi afterburner for rivaturner + hwinfo64) go to a whooping 85ºC, making thermal throttling for core #0. Something was wrong, so I reinstalled the CPU cooler and the temps now go max 65ºC for the cores, 55ºC for the CPU (tCase, I suppose) and doesn't throttle anymore. This temps differs depending on the game too, but usually this are the most common values. For some games (ie, HAWKEN) before this reinstall the freezing was constant: 10min of gameplay made the computer freeze in the way I described before. Now, for Hawken at least, the freezing never occurred again.

However, as you may guess, the freezing still occurs... I've been playing Slender (yes, Slender!!!) and my computer freezes, even at 1280x720 Fastest graphics preset, after 10 min of gameplay! Crysis 2 froze too after 45min, and Prototype 2 after 2 hours aprox. The temps are those I've listed (65ºC max) and there's no throttle so I think it's not just the temperature now. I've been logging the hwInfo64 info for the slender gameplay and I can't see anything wrong, anyway, I'm adding it to this post so you can see it with Generic Log Viewer (http://www.hwinfo.com/forum/Thread-LogViewer-for-HWINFO-is-available).

I've been testing my CPU and GPU also with IntelBurnTest (all OK), Prime95 (temps went really high [almost 90ºC] and i've got a bit scared so I stopped it in the middle :( ), Furmark (OK), etc... RAM tests, Memtest86+ (OK), Windows Memory Diagnostic (OK).
When I use the computer outside gaming, this type of freezing never occurs.

I have no clues and just theories: CPU not stable at high frequencies (turbo mode, 3.9Ghz), GPU not working properly (check GPU D3D Memory Dedicated in the log file attached, 7Mb ???? ), PSU not giving proper voltage [although I haven't seen weird values], MB circuits broken and force a short-circuit when pushing the CPU frequencies and temps, etc....

Pleeeeeeeeeeeeeeeeeeease, help....
Thanks and happy new year!

May be a CPU problem. If your temps went that high it could have damaged the CPU, I'm not sure but it looks like that.
And it could be simply because you don't have a graphics card, you could try and borrow one from a friend to check if it works with one.

Yes, I think I'm going to buy a Cpu Cooler Master Hyper Plus 212 + Cm Silent Fan 120mm to change that stock cooler.



It may have yes, I have the warranty at least... The iGPU deals with the games at totally playable FPS, shouldn't need a top notch card for Slender anyway lol, don't know why is killing the computer.. Luckily, I could borrow a card, but anyway, if that solves the problem, it means the CPU is not ok because the temps are correct in load, isn't it? or 55-65ºC when gaming (even crysis 2 at 720p in preset HIGH [the lowest haha] without dx11 textures keeps those temps) is too much?

Thanks both for the quick response
