Alienware Aurora-R4, Unexpected shutdown when playing a game

it could be bad Power Supply or Overheating.

check your Power Supply. it has a Test Button on the Back. push it and take a look at the Check Light.

run EPSA Test. hit F12 during Boot and choose EPSA Test.

check the Windows Reliability History. open Start Menu and type "Reliability", then pick "Show Reliability History" from the List. search for Errors.

then you can run some Stress Tests. Support and Assist can do that. i'm using Prime95 for CPUs and 3D Mark or Furmark for GPUs.

@edgar > here's a random photo off of the interweb > be sure to insert a blu-wht plus a blu-ylw cable connector into your Grfxcard > if only one color is inserted then the card has access to 18amps of power > when both are inserted, the card has access to double the power (36amps) due to the design choice inside the power supply

a photo posted in the forum last week shows a new 1080Ti powered by 36amps, simply by using both cables, so give yours a try, see if power stays on or still shuts off

hi mate i have changed the power supply as i tough it was bad , but when i got a new one and then tried to play something exactly same thing has happend, whats the story im totally confused on wtf is wrong with my pc maybe its overheating then ? , thanks for reply

time to get a new cooler without further investigation into this.

any suggestions on to what cooler will i get ? i got this pc in 2014 and now the problems only started can u tell me on what to do as i am kinda stuck, what other investigations should i do?

it was a Joke. i told you what to do weeks ago. read my first Post.

I use Intel XTU to monitor CPU core temps, others use HwInfo or any type of monitoring software; you can check CPU temps at approx. time of shutdown, lest the issue is cpu thermal protection related. Software can help rule that out. Try removing any overclock of the CPU and see if it helps. 4820k, 4930k or 4960X? What Grfx card model is it, and does it have a single 6pin, single 8pin, 6 + 8 or 8 + 8 power port. If it's a dual-port, make sure both cables (blu-wht + blu-ylw are inserted). Which power supply did u buy, an original W299G / J556T or aftermarket (Seasonic EVGA Corsair etc)(see note*). Could be a driver issue, a Grfx / Game setting issue or a faulty card. Install a Grfx card temp software, make sure GPU isn't going into thermal shutdown. To help lower temps in the case you can blow out the card, the radiator and the case in general with a mattress air pump or similar, next u can crank up the PCI fan speed

*was the original and/or the replacement power plant the 525watt or 875watt
