Photoshop keeps flickering

[X4nder50]

I have updated Photoshop tonight and it is still flickering and freezing whilst I try to use it. All my drivers are up to date and I can't understand why this is happening. It has been going on for the past month and nothing has changed. I can't finish the project I am currently working on as it is making me feel ill watching the screen whilst it flickers away. I would add a screenshot, but it wouldn't be seen on a photograph.

What graphics card and what driver number?

Try this:

Restore default preferences
Preference settings control how Photoshop Elements Editor displays images, cursors, and transparencies, saves files, uses plug‑ins and scratch disks, and so on. If the application exhibits unexpected behavior, the preferences file could be damaged. You can restore all preferences to their defaults.

Note: Deleting the preferences file is an action that cannot be undone.

Do one of the following:

Press and hold Alt+Control+Shift (Mac: Option+Command+Shift) immediately after Photoshop Elements begins launching. Click Yes to delete the Adobe Photoshop Elements settings file.
Go to Edit > Preferences (Mac: Photoshop Elements > Preferences > General), click the Reset Preferences on next launch button, and then click OK. When you restart Adobe Photoshop Elements, all preferences are reset to default settings.
A new preferences file is created the next time you start Photoshop Elements Editor. For information on a specific preference option, search for the preference name in Help.
