PC has high specs, but still gets low performance

[bencb906]

So, i have a custom build that i update regularly:

CPU: AMD fx-9590 8 core 4.7 ghz
GPU: Radeon rx 480 8gb (2 of them)
CPU Cooler: Thermatake water 3.0
Memory: 16 gb (4 gb x4)
PSU: 1000 watt p2 series
Motherboard: ASRock 970 performance 3.1
Storage: 1TB crucial ssd
Wifi: TP link archer T9e
OS: Windows 10 home

Even though i max out performance, i still get very bad lag spikes in vr games like job simulator, and pc games like pubg, cod, and even minecraft!

Ive been having this problem for a long time, but recently its gotten to the point where my mouse will lag when opening programs like chrome. It also has a tendency to bluescreen unexpectly (irql_not_less_or_equal, kernel_mode_exception_not_handled) I've updated drivers several times, to no avail. Ive also cut startup programs down to the bone, with nothing but windows 10 and windows 10 security on startup.

What exactly is the memory? Part number or link to it.

An air fan for cooling the CPU's surrounding components with a top-down blowing design on them is required.
