A while ago i wrote on this forum to get some help with my computer. It locks up or restarts when playing high graphics games. At first i thought the problem was with my graphic card but then somebody told me to do a ramtest. I did it and i got errors on memtest86 and windows memory testor. Recently i put the ram into my friends computer and it worked fine and without any errors in the ram testors. what is the problem with my computer if it is not the ram. I have a m916 mobo with a 512 MB memory stick that is a pc3200 and it is supported by my motherboard. Please help.
