Windows 10: Upgrade and now flashing desktop/taskbar

I've seen lots of people posting about this all over the internet but as of yet not found a clear fix to my problem. I registered for the upgrade a while ago and the 'check' said that my system was fine. It's a HP TouchSmart 520 and is 2 to 3 years old.

Today I got the message saying that I could do the upgrade and all seemed to go well, no errors throughout the installation. However, as soon as one of the users logs on the desktop just flashes and you can't access anything other than ctrl-alt-del and the task manager.

I've tried booting into safe mode and trying a windows update (boots in safe mode with no flashing) but it finds nothing, and I've looked on the HP website to see if there is a W10 driver. It gives you a file to download which should check for drivers but that doesn't run in safe mode so a non-starter. And if I use the HP website it basically says that you need to use the windows update; which just sits there doing nothing.

If I go into device manager and try to do an update it says that the graphics driver is up to date. I am a bit hacked off that the HP website suggests that it's a product that's not been tested with W10, but the Microsoft check said all ok. Please help *cry

Desktop and taskbar flashing

Hi Ben,

Since the steps provided did not resolve the issue, let's sort this out by checking if this is a driver issue.

Try to
reinstall your drivers manually and update us with the results.

 

Desktop and taskbar flashing

Hello,

Since nothing seemed to work I decided to do a clean install of Windows. A couple of months have passed and the problem hasn't come up again. This seems like the only solution.

I'm just leaving this message here so other people who might have the problem see this.

 

Problem sorted, a reply on the Microsoft forum resolved the issue. I downloaded the Norton removal tool (Norton had been mentioned as a possible cause) and removed it all - and now PC works fine. Now to contact Norton as I'd just paid the coming year's subscription!
