Hello! I've recently bought a new PC, and I'm having problems with it. Here's my system specs:

CPU: AMD APU A10-5800K 3.8GHz
Motherboard: ASrock FM2A88M-HD+
RAM: Kingston HiperX Beast 2133MHz 1.6V
GPU: Integrated one
HDD: Seagate Barracuda 7200RPM 200GB (From my old PC, reinstalled Windows 7 after formatting)

I though that that would work well, but since I bought it, I've encountered some problems:

1) The first problem I've encountered was the CPU overheating. The temperatures in Speedfan were 46ºC on idle and 74ºC when doing stress tests. When gaming it directly shutdowns after 5/10mins because of the use of the GPU seems to make the temperature raise over the CPU limits, where it is already when not playing games. I'm using the stock cooler and I can't afford buying an aftermarket one now.
I tried turning off AMD Turbo and lowering the CPU voltage, which was 1.475V on auto. At 1.325V it was stable, and stopped the overheating issue, but the system didn't run smooth and it froze constantly, so I need help to choose a good voltage, because I have no Idea about voltages,

2)The second problem was that some games froze completly the system, forcing a computer restart or showing a BSOD. Lowering the RAM speed to 1866 solved it, and raising the NB voltage to 1.36v solved it too. The first solution started the next problem, and the second one made worse the overheating one. I used memtest for about a night and passed all the tests without any problem.

3)The last problem was that when playing games randomly the driver crashes and the screen goes black for 1-3 seconds. I know that is the driver crashing and recovering but it happens randomly. I've tried the last Catalyst drivers and the beta one, and both do the same. It started as a rare problem that shown every 1-3 hour of playing when the memory was at 2133MHz, but by the time and after testing some NB voltages and speeds it started to occur mkore often and now happens every minute or so. It's so annoying because it makes most games unplayable. I've tried a lot of speed and voltage combinations and some had better results and other made it worse, but the problem persisted even at 2133MHz.

The games I've played and tested:
-Battlefield 3 (Rarely I've seen a black screen here, but a lot of BSODs when the RAM speed was 2133MHz)
-League of Legends (A lot of black screens that make the game unplayable)
-Farcry 3 (The same as LoL)
-Crysis (The same as Battlefield 3, but with more black screens)
-Starcraft 2 (The same as League of Legends)
-Skyrim (The same as Battlefield 3)
-Prototype 2 (The same as Battlefield 3)

All the games were original and I bought them in Steam/Origin.

I brought it to the shop and they tested it said that it worked perfecty so I can't apply the warranty. I really need help with this problem because I've started to save money 2 years ago and I don't want to feel that I wasted my money, so please, help.

P.D: I apologize for my english, because I'm spanish and it isn't my better languaje ^^

Are you sure the heatsink/fan is mounted perfectly onto the CPU, and the thermal paste is spread evenly? Those temps are too high, especially the idle temps. I have a strong feeling most of your problems are a result of your CPU overheating.

I'm sure, I've tried 2 different 5800K stock coolers with stock and artic silver thermal paste and It only lowered the temps 1-2ºC

I'm stumped. :( It might be an issue with the CPU itself but that is quite unlikely. But if you have tried reseating the fan and reapplying thermal paste and you are still getting those temps and issues I'm not sure what else to think.

I did it but it now puts the voltages too low and that makes the system inestable. It causes shutdowns because of the ASrock thermal protection. I've tried to use AMD Overdrive but it put my CPU at 1.4625V and 4.6GHz and I stopped it because I don't know if that can damage my CPU.
