Windows 7: Toshiba Satellite laptop has Fuzzy screen when reaching Welcome Screen

Toshiba Satellite laptop has Fuzzy screen when reaching Welcome Screen

Hi, I'm having trouble with the screen on my Toshiba Satellite L775-S7352 when it reaches the Welcome screen on Windows 7 Home Premium 64 bit. This happens while reaching the Windows Welcome screen & sometimes it will reach the desktop before going fuzzy. It boots fine into Safe Mode.

I've already checked the HDD and the Memory - they are fine... I've done a fresh install of Windows 7 Home Premium 64 bit from the manufacturer's recovery disks - the screen and everything else worked fine even through the first round of Windows Update (193 files) the machine rebooted after the updates and I checked for more updates. As soon as the installation of the second round of updates began the screen went buggy.

So I formatted the HDD and tried another reinstall - I successfully reinstalled the system and this time the screen went buggy trying to search for the first update for this reinstall...

Is this an issue with the screen or the GPU? any ideas?

Thanks,

Mike

Thanks for the suggestion, only thing is that I'm in the middle of a move. My desktop is still boxed up, but I can get a hold of my HDMI monitor and run it off of the HDMI port on the laptop.
I will try to do this today. All I need to do is go to my storage unit and find the monitor and cable...

Thanks for the suggestion, I'll report back on what happens...

OK, when I hook up the external HDMI screen, Both of the screens work flawlessly!

What's up with this deal?

I've been looking on YouTube to videos about replacing screens or solving problems with Black Screen. I didn't exactly have a Black screen, but maybe if I use the method they show it may fix my problem...

Any thoughts?

Well that's interesting I would of expected the external be ok and laptop screen would still be fuzzy. Are their any yellow marks next to anything in device manager.

Get and install the video drivers directly from Toshiba, re boot.

I checked that out at the beginning of the problem. There are no yellow flags.

Odd that it'd work with an external screen plugged in, I was going to say that if the external monitor was also fuzzy, it's a problem with the video card in the laptop, but if the external monitor is not fuzzy, then it'd be the screen in the laptop... however, I'm not sure what would cause it to start all of sudden once you get to the log in screen on Windows, but isn't present in safe mode.

Could very well be a driver issue.
