My games didn't run "normally" as before

[namhhgames]

I've just built my new PC and install a clean windows 8.1 (format the drive before installing) but I'm not happy with my new PC.

I tried playing Battlefield 4 and GTA IV to check out my new PC but it didn't run the way I expected. BF4 drops frame randomly while playing and at every checkpoint. And sometimes it crashes. With GTA IV, Niko won't answer any phone call, it's like he just skipped it. (the phone rings, I pressed Enter to answer and nothing happen, but the mission from that call still pop up - it's not skipped). My old low-end PC can run it without any bugs like that (just low FPS as it can't handle much graphic of course).

I though it was because the game files is corrupted as I copy and paste the game, so I downloaded the fresh game and reinstall but it's the same. I tried to scan for bad sector on my HDD but there is none. CPU chipset and GPU drivers is up to date.

My PC:
CPU AMD A10 5800K 3.8GHz
GPU GTX 760 2GB
RAM 4GB 1333MHz
PSU 470 ACbel

One more thing, when I use default BIOS settings, my PC dumps or freezes when I play games (high load), tried to OC CPU to 4GHz and RAM to the fix freq 1333MHz, it still the same. But when I keep the RAM at 1333MHz and make CPU auto, it can handle my games and pass all test of the ycruncher stress test. Windows boot is also slower than my old PC. I don't know if it's because of my CPU or the combination of AMD CPU and NVIDIA GPU. Any idea guys? Thank you.

Umm...how was your older system built?
This one isn't THAT good, as the gpu is nice, but weak for maxing out ganes (if that's your intention), and it doesn't have a CPU, but an APU...
4gb 1333mhz RAM might fall a bit short in capacity, but should be fine as long as they're at least in a dual channel setup with a CL of 9 or lower.
You should, however, immediately change that PSU. Unbranded ones are beyond terrible, and 470w is barely enough for that system...

As I check in memory tab of CPUZ it says Dual (it's 2x2GB) and CL is 9 clocks (it said). I don't know if my RAM are correctly configured. I tried another kit RAM 2x2GB and it's still the same.
My old PC is Intel Pentium Dual Core E5500 2.8GHz, GPU GTS 450 1GB OC edition, RAM and PSU are the same ones. My new PC currently run games at maximum settings (around 40fps - it's good for me. Its only problem is that it's not stable). Someone told me that my PSU is enough for this rig so I didn't pay much attention to it, looks like I should give it a try. Thank you anyway.

Well, there isn't much about RAM configurations, except clocks, CAS latencies and channels (as a rule of thumb, if the mobo supports their frequency, you're ok as long as they're inserted in evenly colored slots and as long as they're not hybrid, like a 2gb module and a 4gb one)

About your PSU, I said that because wattage is enough, but quality usually isn't good on less known/unheard-of brands. With units like that it's like playing poker; you're trying your luck, and you're either winning big or losing big...
I cast my judgement too hastily however, as a quick Google and you get to know how ACbel is. They're solid enough for non overclocked systems, but they're still relatively unreliable under high load conditions.

In any case, it's only normal it's not constant. Your GPU is capable of maxing out games, but not enough for keeping them at a stable framerate, and the APU doesn't help at improving the situation. This is obviously valid for 1080p and above, as 720p will run relatively flawless. I'd give a try to a 1600x900 resolution if you're on any display below 22"; it shouldn't look too pixelated and should give you a nice framerate boost.

Forgot to mention that im running games at 1280x1024 as the monitor's max res.
What about the games bug like the characters won't answer any phone call (GTA IV)? And ya... BF4 also have bug. When I press Esc, it brings up the pause menu, then I press Esc again it's supposed to close the menu and back to the game but it didn't, it just closes the menu and opens it again. The only way to back to the game is to use the mouse and click on Resume. That's weird, I don't think hardware could effects the games like that.

Your games aren't cracked versions, are they?

BF4 is licensed standard version.

Well, I do not own those games anyway, but I've never heard of those bugs...
Make sure they're patched and run a game cache check (a.k.a. repair; Steam has that, I suppose Origin does too) just in case, something might have gone wrong during installation.

I'll try changing PSU, hope it fixs. Thank you.
