Strange pc crash

[Jacob1264]

Hello guys, so i just built my new pc and it's awsome but there is a slight really annoying problem i have bumped into. My pc just crashes whenever i start playing games after a while and instantly reboots, i have tried reinstalling windows, cleening the whole pc. In my pc right now i have a gtx 1080 ti oc 11gb, ASUS ROG STRIX Z370-F GAMING, Samsung 960 EVO NVMe M.2 SSD 250GB, Corsair Vengeance LPX Red 2x8GB 3200mh, Corsair Hydro H115i, Corsair RM850X 850W and a Intel Core i7-8700K 3.70GHz and it just doesn't work. One note the light's on the motherboard does not light up. I have tried every thing that came to my mind so now i'm asking you all out there for help.

What are your temperatures like while gaming? It sounds like your PC is overheating.

@Crunchy Dragon Gpu while gaming is around 60-75 and at worst almost 80, cpu is around the 60-70 mark when my cooler kicks in. But sometimes crash times vary it can either be verry early or after a while.

That sounds pretty high, what do you mean by the CPU "is around 60-70 before the cooler kicks in", do you mean to say that the CPU cooler doesn't turn on before it reaches a certain point?

@Crunchy Dragon Yeah or like the cooler sist at idle point and after a while when the cpu hit's those temps it start to turn up but then it just freezes and dies. Same goes for the gpu it doesen't spin it's fas untill ig get's to it's 60's anf higher

Set a fan curve using a utility like SpeedFan so the fans are always running.

The CPU Cooler. I like loud things

[Jacob1264]

@PCPartListsYT  it get's really loud by itself when you have 2 x 240 mm fans

@Crunchy Dragon A small uppdate i found out now is that now only some games crash and some don't.
