Recently I upgraded my PC changing out my i3-4170, msi pc mate, and 8gb ddr3 for an R7 1700, b350 tomahawk, and 16gb (4x4) 3000MHz corsair vengeance. I also have Corsair RM850x, Gigabyte GTX 1070 G1 Gaming, and standard ssd/hdd. Every since doing this I have had nonstop crashing in every single game I try to play, and I've ran out of ideas on how to fix.
On top of this, my RAM registers as me having 16GB but only 8GB actually works, unless every time I go onto my PC I go into BIOS, change RAM speeds (which doesn't really change) then launch, it then uses 16GB which is weird.
In games like Overwatch it'll say: Your rendering device has been lost, I've looked all over their forums and downloaded all the drivers for my PC and don't think this is the problem. I also don't think it's my GPU as it was working fine in my last build.
In R6S when I crash my video freezes but I can still hear audio (sometimes looped)
So far I've tried:
Reinstalling Windows 10 twice
Updating BIOS to latest version
Downloading chipset drivers
*Want to find a way to test ram on its own if possible without buying something like Aida64
GPU does hit like 68 celcius which may affect it
I've also tried fixing my memory with the maximum memory boot menu but can't get that to work, so I just sleep my pc to keep the memory at 16gb instead of going into bios every time
I've tried underclocking my GPU and have cpu on stock speeds, same with ram on 2133 standard
Thanks for any help you can provide, I'm really stuck here and would hate for this to be a hardware problem and would like any help possible. Up for any suggestions
