B1930N Screen Flicker

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...

"the whole PC jams"?

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?
