I have a year old 17" Toshiba Laptop that up until recently has been working great. Untill about a month ago I started having a problem of when I plug in a flash drive the screen will randomly flicker when I am trying to do stuff. There doesn't seem to be a pattern to the flickering it sort of seems random. I am using the latest display drivers. i have tried almost 10 different flash drives. I cannot seem to figure out the solution. I am close to taking it back since I bought the extended warranty and having them fix it. The only thing I haven't done is try reinstalling Windows but I don't want to do that unless I have to since everything on my computer still works fast.

OS: Windows 7 Ultimate 64-Bit (SP1)

Try using safe-mode or a live-CD in order to determine if it is a driver issue. I know you said you have the latest drivers, but it never hurts to double check.

See if the screen flickers when you plug in the flash-drive in safe mode. If after a awhile of testing it and the same problem occurs then it is a hardware issue. Also, having the latest up-to-date drivers doesn't always mean that it is a good thing.

I have Windows 8 installed on this computer in a dual boot and I just tested and the screen doesn't flicker in Windows 8 so I am assuming it is some weird driver issue.

From what I can tell, you do seem to have a driver problem. Someone suggested restoring to a previous point; I recommend trying to restore even though your restore-point doesn't go back to when the problem initially started.

You could try looking up the drivers for your computer then manually installing them if the restore-point fails.

If nothing seems to work what you could try backing up your data and re-installing.

i tried the restore point and reinstalled drivers. So now I am going to reinstall Windows when I have some time.

try restoring to a previous point, where it worked without flickering. Like someone said, latest driver doesn't always mean a good thing.

I don't have a restore point that goes back that far...

Key word "Laptop"

Check the connection for the video cable. Had a few clients bring me laptops was dodgy connection.

Like open up the laptop? Because the cable I have coming out of it to another monitor flickers also.

Is it? Did not read it all :/

Driver or GPU problem.

Load a Live CD up and test.

When I boot Windows 8 I don't have the problem so I'm certain it is a driver issue now.

Not an issue I've had before but the first thing I would try would be going to the manufacturer's website and looking for an old version of the driver. If you've recently updated the driver it may have some bugs.

I haven't updated the driver. I am almost considering reinstalling Windows now....

It's Windows. I am convinced of that. This started to happen 6 months ago, but I can't swear exactly when. It happens on all my desktops, whether XP or Win7. Microsoft added something that does this. I am suspecting it does it when an app has to change something in the registry, because of the behavior that changes your whole screen in Windows 7 when an app has to have administrator rights.
