i5 4670K Overheating Poblem?

Hi, about a month ago I bought my new Gaming pc with the following specs:
i5 4670k; ASUS gtx 760; corsair 750W psu; ASUS Maximus VI Hero; western digital caviar black 2 Tb.
The problem is that at the 3rd day of having my computer I installed Battlefield bad company 2 (that kinda pushes the cpu) , and I could not play for more than 30 to 60 minutes before the game and the system crashed. All this was done without the case side pannel (antec eleven hundred) for max air flow. After searching a little bit I found out that some people were blaming punkbuster for similar crashes and also said that punkbuster could not handle certain cpus at certain frequencies ( mine was at 4.2 Ghz) so I just quitted the game. After that I installed Farcry 3 that had similar problems (random blue screens) but much less frequently (about once every 10/15 hours of gameplay). I also played other games as League of legends and Payday 2 but those didnt had a single problem. About a week ago I mounted my case side pannel as there was a pile of dust accumulating inside, but after that blue screens become much more frequent, even started to appear during LoL and Payday 2 gameplay, [strike]some[/strike] lots of times even appear while I install programs or render videos. When I have a blue screen it shows the bccode 101 which I think it's related with overheating, but even when I take away OC and disable turbo mode so that the cpu never passes 3.4Ghz it still crashes. My cpu being an Haswell does run quite hot quite quick, and my GPU does not help as instead of blowing the air outside the case blows the air up (to the cpu fan) and when I say up it is because the air doesn't even go sideways, just up. But my GPU never passes 64 C under load. I have runned stability test for the cpu (4.2Ghz), gpu, ram, and all passed except some cpu test like OCCT that stop midway because of the temperatures passing 85 C, however prime95 did not crashed my pc after 3 hours of testing.
After this big wall of text my question is: Is the problem realy the cpu temp? (As even with everything stock it crashed and BSOD right away.)
Or can it be a damaged hardrive?
If you think that the problem is CPU temp then have u met someone that has the same problems? Or what coolers do you recomend?

I think it's a bad idea for using the stock coolers specially on Haswell CPUs as firstly they are not meant for Overclocking and secondly they don't have enough thermal mass to dissipate the heat quickly. I think that's the reason you are experiencing frequent crashes on games like BF bad company and far cry 3 which really do use the CPU a lot and because the stock cooler is so weak, it can't even handle that much of heat and makes your CPU hot.
I highly recommend that you should buy at least a Hyper 212 evo CPU cooler from cooler master as that's a really cheap and awesome cooler and will keep your 4670k well under 70C on full load and will also give you a considerable amount of headroom for Overclocking, maybe 4.4 or 4.5 as each chip is different.
You'll be more than happy after installing the hyper 212 evo :)

The problem is that i get blue screens without OC just for the temperature of having the case closed.

Ya you will get blue screens cuz your CPU is overheating because intel stock coolers just can't handle that amount of heat that Haswell produces. The stock cooler is really not enough to even run Haswell as the chips sometimes tend to cross the 90C mark on stock clocks just because of the stock cooler's small thermal mass and the cpu starts thermal throttling to protect it from damaging which is why you come across frequent blue screens.
Like I said before, your best bet will be to buy a hyper 212 which will easily handle the heat produced by the chip because of the large thermal mass.
You could also mount a second fan to it if you wish.
The Haswell chips are really capable but only If you match it with a good aftermarket coolers even for running it on stock clocks.

I hope this helped. :)

Sorry for not replying earlier but the blue screens stoped after I created this thread, however I just got a different blue screen. (this one never appeared before)

Prime95 never crashed my computer, even at 4.2 (turbo) and as far as I can see whenever my computer gets to 100 C he decreses the turbo clock. Answering your question, max temp at stock is 68 C.
By the way, yesterday I noticed that my mother board Q code monitor was showing "30" which stands for S3 sleep state, i don't know if that helps.

OK, I see several issues here:

1) You are attempting to overclock with the stock cooler. Even going back to the Core 2 Duo which used virtually the same exact same stock cooler, the intel cooler has always been barely sufficient. My 4670k at stock speeds runs as high as 76°C under full load (I use Intel Burn Test). Going any higher than this is a real risk. If you cook your CPU repeatedly, you run the risk of damaging it. It's true that it has built-in thermal throttling capability, but that is an absolute last resort, not something designed to be used every day! Intel sells an unlocked CPU because it knows aftermarket coolers exist that are superior to its own and wants to allow people to use that extra cooling capacity. But if you don't actually have that extra cooling capacity, don't even try to overclock!

2) Random blue screens in my experience point to memory problems. You should start by setting your CPU to stock speeds and booting into Memtest (download an iso off the internet and boot from the CD) and letting it run at least 4 times. If you get any errors, reduce the speed of the RAM by one step and repeat to see if it is the RAM not meeting its own specifications (I have seen it before plenty of times, the RAM says 1600 on the package and works perfectly at 1366 but errors at 1600). Now, with the "i" generations of Intel processors, the memory controller has been moved from the motherboard to inside the CPU itself. In my opinion this means that the bit-flipping could actually be occuring on the CPU itself, as a result of you overheating it! And yes, it could also be the hard drive, but I deem that unlikely.

3) You have insufficient case air flow. Leave the case open for now since it has proven to yield better temps that way. You should either retrofit your current case to accept more fans, or buy another case that has more fans and better ventilation. I have my 4670k and a GTX 670 (which is equivalent to a 760) in a Cooler Master Storm Scout 2 Advanced. Even with just the 3 fans it came with, everything stays nice and cool, however, I will of course be adding more fans down the road once I make some upgrades. Post a picture of your case with the side panel removed, and I'm sure some forum members would be happy to help you correct any obvious errors with your setup. It may be as simple as moving a few things around, but I'm almost 100% sure that you simply need more air flow.

Thanks for the reply and for the warning on the throtle. About the CPU clock, the 4.2 its the default turbo clock on my chip since the first run of windows but I'll lower it. About the RAM I already had thought about that and runned 4 memtest for about 5 hours and no errors popped out so I guess its not a RAM problem.
About the air flow, I am not planing on buying a new case for now because it only has 1/2 months and it was quite expensive where I live. I am however planning on buying water cooling and just cut my case so I can fit it somewhere.
