Display starting to go haywire

[flashmantomas]

Recently, my display has started to go haywire, flickering and scrolling with vertical lines.  I have tried uninstalling the device driver and reinstalling, to no effect.

Are there any suggestions I can check out to try and resolve the issue

Many thanks in advance.

I reviewed your post and I understand that you are facing issues with the display on your computer.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you update the BIOS and the graphics driver from the below link and check whether the issue is resolved.

If you continue facing the issue, then boot to BIOS by tapping continuously the F10 key while restarting the computer and check whether you can duplicate the issue in the BIOS screen.

Let me know how it goes and you have a great day!

Hey Foss, that seems to have done the trick.  Thanks!

Hey Foss, I have another problem with my display, that has been going on for about a year. When the machine goes into hibernation, it has images of prior sessions displayed, that appear to enlarge over time. I wouldn't worry about it, but I do development work, and one of the images is a screen from my IDE, which could potentially pose a security concern.

I don't know if I should open a new issue, but since you did such a good job on the haywire issue, I thought I'd run it by you first.

Thanks again in advance

Hey, well it's back.  Could it possibly be that the machine isn't getting the proper power input?  Several months ago, I tripped on the cord and the machine landed on the power supply tip, bending it.  I was able to get it bent back into shape, but there must have been a bad connection in the tip, because the power supply eventually stopped working.  I just replaced the power supply, but I could only find one that was compatible.  It is putting 150 watts just like OEM supply, but could it be delivering the power at a level?

PS:  The flickering problem seems to only occur when I wake the machine up.  It continues for a few minutes and stops.  It's driving me nuts trying to figure out what the problem is, lol.
