    Hey all,

    Recently ive been having a couple of issues with my mac; the thing is i havent used it in a few months.

    anyway lately when i have been using my computer if i dont use it for a few minutes it will freeze, causing me to force it to shut down. and the other issue is kinda hard to explain but for some reason when i am gaming the picture has been acting up lately; i can see almost perfectly fine but there are vertical lines all over the screen - about 2cm long...the lines only seems to pop up on 3d imaging.

    i have an iMac PPC G5 with 512mb ram

    like i said i have not used this computer in a while

    thanks in advance for the help

    I would try increasing the memory of the iMac by buying some more RAM.
