Hi all, I have a gaming rig which I put together back in May 2015 - it's been going great so far but in the last two weeks it's been restarting itself suddenly when playing games.
I've done all I know to try narrowing down the issue but I'm having some trouble singling out the PSU or the GPU as the culprit.
I've ruled out the CPU via Furmark CPU burner and the RAM's fine according to memtest86+.
When I tested the GPU with Furmark it ran for about a minute and then the system suddenly and immediately restarted. This doesn't appear to be a temp issue - temps reached 75C on Furmark before failure but some games will cause this issue within seconds of launching - for example Overwatch will cause this issue immediately on the menu screen! In this case I checked a log made with Speedfan and GPU temp only hit 45C.
Checking the Event Viewer after this happens shows a Kernel-Power event has been logged upon reboot (EventID 41, Task Category 63). This seems to directly condemn the PSU, right?
May as well mention for completeness that there's a fair bit of dust in the case - not enough to make a sweater from but can dust have an impact like this? Since noticing this a can of air has already been ordered ;-)
And finally, my specs;
CPU: Intel Core i5-4690K
Motherboard: Gigabyte GA-Z97X-Gaming 5 ATX LGA1150
Memory: Crucial Ballistix Tactical 2 x 8GB DDR3-1600
Video Card: EVGA GeForce GTX 970 4GB Superclocked ACX 2.0
Power Supply: SeaSonic G 550W 80+ Gold Certified Semi-Modular ATX
1x M.2 SSD, 1x 7200rpm HDD, 1x wireless NIC

Hope I've provided enough detail - happy to provide more if you need it.
Thanks all + all the best!
