I use a PC and for the past 2 months my photoshop program has had a strange issue. Whenever I try to open a photo on photoshop my computer's display starts to glitch and the photo won't show on the program. Even after closing photoshop my display continues to have graphics issues. How do I fix it?
Update your video card driver straight from the website of the manufacturer of your card. Do not rely on Windows Update or Microsoft. Those will give you outdated drivers most of the time and will lie to you saying you're up to date when you are not.
That should take care of it, unless your video card is underpowered to begin with.
P.S. Photoshop has nothing to do with the deficiencies of your video card or its driver.
