I've been getting a corrupt display the past 24 hours. At first it was intermittent and only when creating a new email in Outlook, but it's been rapidly getting worse.
First it was on okay screen but gave me garbage where I dragged the mouse. Then later it was a black window with garbage where I dragged the mouse. And only with new items in Outlook.
See these two images:
![]()
![]()
But then when I took a third screen shot of that behavior with Snagit and went to save that in Snagit Editor it did the same thing while in Snagit Editor, with a bad display where I moved the mouse:
![]()
Outlook doesn't seem as suspect since the last image, which happened while in Snagit Editor, not in Outlook, but Outlook was open when that happened.
Then, I closed Outlook and returned to this thread that I had started in the forum in Chrome, and was able to go back to typing this post and it's all working normally. It's been too intermittent and is too soon to say if this is only happening when Outlook is running -- though that does seem to perhaps be the case. I was not only able to finish typing this post fine after closing Outlook, and upload the images with my FTP program, but also go back into Snagit Editor, all with no problems.
I was also then able to open Word and move around in a doc and that seems to be working fine, too, though I didn't test it a lot.
My system hasn't changed in a long time as far as I know (other than the Windows 7 updates I always run when they're made available).
I might mention that once in a while this machine has exhibited lag in terms of responses to mouse movements or keyboard input, but not very often and then it clears up quickly. Only in the recent months. Not often at all. Usually when I'm using WiFi (desktop machine with USB WiFi) and a VPN, not that I know if that's related.
Other than that, the machine runs like a top.
System:
i7 with 16 GB RAM.
Windows 7 Pro 64.
Office 2010 Pro.
I have a Logitech mouse with their SetPoint running. It's been the same driver version for well over a year.
The graphics card is an NVIDIA GeForce GTX 750 Ti. The driver is dated 3/16/17, version 21.21.13.7892 (I've made a habit of not allowing the graphics card driver updates that are offered up with Windows updates, since I never need the enhancements, which are almost always just for gamers, and since once in a while they've introduced issues that required removal).
So, I'm going to do an image backup of the whole system before I start to try various fixes.
The question is if I should focus on:
- updating the graphics driver (seems the obvious first choice, I guess)
- reinstalling the SetPoint software
- reinstalling Outlook? (I hope not; a bigger project than I have time for)
- replacing the video card
- anything else
Thanks!
