Hi Welch and Bryanl.
The lines, usually one or two, would be at the very top right, or at tops of windows, further down. Randomized broken flickering white and black lines, more solid on the right.
Original driver was 8.86 from disc. Upgraded from site to, 11.12 to try and fix lines, in early Jan. Thought was fixed, then happened again on Jan 29.
I had lost my patience after one day, trying to get the lines happening again. Did not see lines. That's when I updated drivers from 11.12 to 12.1
I really don't want to uninstall and put the old drivers back to verify, as I could be waiting weeks to confirm.
I have three other dedicated hard drives, that I use separately in a bay. Win7 64b with driver 8.86 for paying bills, Win7 32b 8.86 driver for watching video files,
and Winxp for Games, as well as my workhorse ssd win7 64b 12.1driver. Tried today, being on each of the four drives for a couple of hours. No lines.
Is this a wild goose chase or what?
I am happy for now. Couple of theories. Random Neutron from space, or the old favorite, blame it on Windows, this time, say, Windows Silverlight.
Definitely not heat, as I installed heatsink on top of original southbridge heatsink and changed APU heat sink to cooler master, with push pull fans. Idle system temp 36C, Apu 12C.
Anyway, below is what I copied, from web page of another forum, Whirlpool Forums Addict.
They seem stumped as well.
For the past few weeks I have noticed a couple of horizontal flickering white lines at the very top of browser, email & folder windows. The flicker occurs in the browser randomly or when I switch between tabs, with the folder windows it happens when I hover the mouse on those title bars. This computer is only about 4 months old, could it be the video card or monitor causing these problems? Maybe the monitor cable?
AMD A8 3850 (on board video)
OCZ Vertex 2 – 60GB
Seagate Green 1TB SATA
Avexir 4GB (2 x 2GB) DDR3 – PC3-12800
Windows 7 64bit
Then I'm pretty sure it isn't the monitor.
Have you tried upgrading the video card drivers?
No I have not. I did however change the video cable, which I thought had fixed the problem, because that day it didn't do it, but sadly it's doing it again, this time the lines are not just at the top but randomly at any point of the screen.
Could be my imagination but seems to only start doing it after the computer has been on for some time? Maybe after it is getting hot.
