Question Screen blacks out randomly

[nlightningmusic]

My screen(s) randomly flicker or go black for up to 3 seconds at a time during "menial" tasks (like having YouTube open while browsing Reddit or opening Telegram or Google Docs). It's been doing this on ALL of my monitor setups, from when I used three 1600x1440 monitors, to when I switched to only one monitor, and even now when I've got a 3440x1400. Strangely enough, I experience almost NO issues when trying to game, but I get tons of issues when I'm trying to do tasks that I wouldn't expect to be as graphically intensive. Is it a GPU issue?

--Specs--
MB: ASUS M5A78L-M PLUS/USB3 (w latest BIOS)
CPU: AMD FX-8300
GPU: Gigabyte GeForce GTX 1050 OC 2GB
RAM: 2 x Crucial DDR3 4GB ; 2 x G.Skill DDR3 4GB (16GB total)
PSU: EVGA 450B
OS: Windows 10 Home v1903


According to PCPartPicker this build should only draw around 256W, so the PSU doesn't seem like the issue. Anyone have any idea why this might be happening?

Is it possible to try your GPU in another system?
