Apple error 4mem/61 0x7a129390

A vertical band (about an inch wide) appeared on the screen of my MBA and after testing the computer I get the following error code (Apple error 4mem/61 0x7a129390). Could someone tell me about the nature of the problem and the possible solutions?

Thank you very much
