Why Is ue always freezing on my Windows 10

Ue4 is freezing and crashing every 20–30 minutes I can barely get anything done it’s annoying.
This is what I have at home it’s not bad at all so I don’t get it why ??? Like is it a bug or something???CybertronPC Electrum QS-A6 - MDT - 1 x A6 A6-7400K / 3.5 GHz - RAM 16 GB - HDD 1 TB - Radeon R5 - Win 10 Home 64-bit -
