I have suddenly had a problem with my computer. I rebooted it and there are strange blue lines on the left of the screen. They appear when booting the computer up, and when the computer is on. I was thinking it was a problem with drivers, but do drivers effect the computer while booting up?
I tried removing the drivers and downloading the latest Nvidia ones too. I also tried 2 different monitors, and i tried putting my graphics card in the other PCI express slot.
The strange thing is, when i tried to take a screenshot of these blue lines, they didnt appear on the screen, i can only see them with my eyes. I am wondering if my graphics card is faulty, do these symptoms sound like a faulty graphics card?
If it is showing those multiple lines,even at the POST screen it is almost certain the video RAM is at fault.
I do n't suppose this is still under warranty? Try to find the invoice and check out the suppliers website.
This is a absolute last ditch 'kill or cure' fix. Use it entirely at your own peril, and read the whole thread before you begin.
Two others here have used this, one worked, the other did not, so there is no guarantee it will work for you.
