[KennuGaming]

My pc crashes when i try to play games and i have already changed my memory and have sent my computer to repair twice. It doesnt even show a blue screen of death, it just turns the screen black and reboots.
My specs: Its a Lenovo Y900-34ISZ
Intel i7 7700k
GTX 1080 8GB vram
24 gb of ram
2tb hdd
240gb ssd

When i check task manager when its about to crash my cpu is like 20% and gpu is 20% or 30%

PSU: make, model, wattage, age, condition?

Look in Reliability History and Event Viewer for error codes, warnings, and even informational events that correspond with the PC/Game crashes.

=========

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, and jumpers are fully and firmly in place.

625 Watts - correct?

Without knowing much more regarding age and condition, my thought is that the PSU is in the early stages of failure.

The PSU may simply be unable to provide the steady power levels necessary for game play.

yeah i wanted to guess that cause the pc is about 4 years old and its like 615W. Should i just buy a new PSU. If yes, then what psu should i buy?

Do work out the wattage requirements and allow room for growth.

If budget permits do not skimp on the cost.
