Okay so i've had this problem for a while.When playing games my pc just reboots.Now i've tried many things to fix this and none have worked :/
What i did:
-Changed the thermal paste on the gpu
-Underclocked the gpu
-Underclocked the cpu
-Underclocked the max power usage on gpu
-Upgraded the drivers
-Downgraded the drivers
-Updated windows (156 updates in total)
-Re-installed Microsoft Visual C++ (all versions)

Specs:

Gpu:R9 380X
Cpu: i7-7700k
Psu: Chieftec 600w
Ram: 8gb ddr4
Hard drive:ST3500413AS 500gb

"Psu: Chieftec 600w" this would be my top suspect, most Chieftec psus are garbage.

This type of behavior is generally a temperature issue or a power supply issue. Assuming your temperatures are fine, the PSU would be the next place to look at, especially considering this is from a brand that mostly sells very low-quality power supplies. With a CPU that cost over $300 and one of the most power-hungry single GPUs ever made, I'd be replacing that power supply even without these symptoms.

When it reboots does it just go off like a light bulb (that is, without the Windows reboot sequence)? If it just goes off like that, that sounds more like hardware of some kind than a driver issue. The PSU brand is unfamilar, and a Google search came up with mixed results. One model had a good review but other results indicate the quality of their units vary.

It completly shuts down in a second,there is no kind of warning that the pc is going to shut down.And then it turns back on again.

The temps are fine,i think.The gpu dosen't go above 77-80c.And the cpu dosent go above 75c.The cpu and the gpu have new thermal paste.

That's a fairly mediocre PSU as well and possibly a bad one depending on which variant you end up with.

The least expensive PSUs worth buying tend to be the Corsair CX 450/550 PSUs (black and gray letter, *not* the CX 430) or the SeaSonic S12/M12 series.
