PC is randomly turning off

So i recently bought a pc and for the first few days it had been working fine, other than the fan making a noise as it was touching another part, but for the past week or so its been randomly turning off. At first I thought it was a lack of ram as I only have 8gb and I was trying to stream the game I was playing. When it happens the screen just goes black with no error code or anything, all lights turn off and it just turns back on. When I check the event log i get errors but they don't seem like they are causing the problems as I've tried to fix those issues and it hasn't changed much.
I've checked the internal temperatures and they are fine even when running a game. My specs are the following:

1. Intel® Core™ i7 Quad Core Processor i7-7700 - 3.60GHZ
2. GIGABYTE H110M-S2H
3. MSI Nvidia GeForce RTX2060 8GB GDDR6 - FACTORY OVER
4. Seagate Barracuda ™ 1 Terabyte 64MB Cache 6GB/S 7200 RP
5. ADATA 120GB 2.5" READ 520 / WRITE 320 MB/s
6. TorQue 500 WATT 80+ CERTIFIED BRONZE

I hope someone will be able to help or give some advice.
Thanks
