B1930N Screen Flicker

by meridius10 / April 20, 2011 6:31 PM PDT

I may occasionally get some vertical screen flickering (ie. a few lines down the screen) and the whole pc jams.

Was wondering if this is due to the monitor vga cables not being connected properly, or is this a hardware fault, or is this a Samsung monitor issue...

Yes and I have to hard boot the pc as the screen problem freezes the operating system.

Unlikely a freeze of the OS is caused by anything (such as a cable or a monitor). So it's something inside the case. Could be videocard or the driver. If it's onboard video (on the motherboard, not a separate card) it could be bad RAM also.

Thanks for these leads. I ran Memtest86+ from a live Ubuntu cd and it showed some RAM errors, so I'm guessing I should ask the supplier for replacement memory?

Do you know of any good and free software that tests motherboard components?

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
