Red Screen Of Death problem

[Bilel BM]

hello i have a big problem with my pc everyday i get like 2 rsod and 4 bsod all of them with errors like memory_managment ,critical_process_died(most of the rsod had this),system_service_exception ..........
i tried to test ram it was okay i even tried one ram at a time (same problem)
i disabled turbo boost and everything in cpu (same problem)
cpu temp never passes 70°
gpu underload below 70° too temps are okay
i tried to stres cpu and gpu i used intelburn test (no rsod but some times i get a bsod this only happens in windos 10)
i run FurMark for long while nothing happens
MSI Kombustor too but no rsod
the rsod only happens when i play bf4 or gta v and some other games but i can play for a day without a single bsod or a rsod i have no idea what can cause the problem (since its not overheating problem)
whats confusing me is that errors do not happen when stress testing only when gaming please help
PS: cpu and gpu are not overclocked
Specs are:
gigabyte h55n-usb3
i7 870 @2.93GHZ
8GB DDR3
Sapphire HD 7870 GHZ edition
Sandisk 128GB SSD
Psu adata bn-55 550watts

How many versions of Windows do yo have on your system? Are you dual booting? Since the system is built with drivers that have maximum support for Windows 7, I'd advise on downgrading to Windows 7 64bit. Going through the rest of your specs, are you sure your BIOS and remaining chipset drivers are up to date? Uninstall your current drivers using display driver uninstaller and reinstall using the latest driver found off AMD's site.

You're temps standing at 70 Deg C for CPU load isn't a good thing, you should invest in an aftermarket cooler later on. You should run memtest86 for at least 10 passes before declaring it fit for duty or faulty in operation. You should also take a look at a more reliable PSU following this guide(alongside some more info) as the unit you have isn't reliable to run your system alongside a HD7870.

Further reading. Since it wasn't stated in your specs, is your case airflow good? Without much though I'm going to say your PSU is the cause of all this but you'll need to perform the above checklist since there are too many variables in the crime.
