Question Monitor turns off randomly

Feb 10, 2021
Hello guys, i'm sorry for disturbing your sleep but i have a Issue, i just bought a GTX 1050 TI OC version 4gb DDR5 and my CPU is a i5 3450, the problem is my monitor turns off randomly while playing games but my pc keeps running, only the image on the Desktop will stop working until i turn the PC manually off, i have a 230V Power supply and i did some researches on Google, it says its enough for i5 3450 and GTX 1050 TI since it will use only around 150Watts together. PLEASE HELP!
