PC does is not stable

[Sebamiz3r]

Hello,

below decription of my recent problems:

last week, while gaming, PC truned off. While rebooting I noticed artefacts on the screen, they were wisible untill windows should start - then display went into "power saving mode". Artefacts were visible in BIOS and when I managed to launch it in safe mode. My frinend borrowed me graphic card and PC tuned od with no errors. I bought a new graphic card on friday and installed it.Everything worked fine, all games launched were playable without any problems. Today I launched PC and during reading internet display turned off. I turned it on again, everything worked ok untill Windows loading screen - display turned into "power saving mode" and my keybord also lost backlight. I have waited some time and tryed again, PC went up normal, but when I tryed to launch browser ahain i saw black screen. I would like to diagnose what might be the problem. My specs:

Motherboard: AS Rock P67 Pro3
CPU: i5 2500K @3.3GHz
RAM: Corsair Vengeance 16GB 1600MHz
Graphic card: Nvidia ASUS GeForce GTX 980 STIX DCII OC - before I had MSI GE Force GTX 460 1GB Cyclone
PSU: Chieftec APS-650C (80+)
OS: Windows 10 Pro
SDD: Plextor M5 Pro 128GB
HDD: WD Caviar Blue 500GB

thanks for your help in advance.

I also saw that while I launch any app grapic card usage raises a lot:

I have notice one more thing, my processor is always at 100% usage. I have noticed it bu looking a bit longer at hwmonitor. Task manager switches processes that consumes processor so i can not poiny which one or more that are responsble for using my processor in such way.

I cant really tell, from Speccy, but I think the issue might be with your power supply. Can you borrow another one try it? Or try the video card in another computer?
