Installing a new video card

Possible you need to reset the PS3 . Also check if the CD is reading, is compatible and not a pirated version.
Finally check if the parental control is active.

last night bought a guitar hero and the wireless light dont work

thats odd.. :/ I've played with the kramer on 2 before, i think, so i don't know why it wouldn't be working...

where did you buy that????/ change that cd to guitar hero 3 cd again

try readjusting the wires.

check the battery and they resync the remote.

i also have the sam eissue. i bought it used off somenbody. i'm kinda pissed off. is it a dongle issue, button issue, or guitar base issue?

First of all, make sure the card is in slot one. I'm not sure about Guitar Hero 3, but I know many games default to searching the first slot (the one on your left as you look at the system).

Assuming that's not the problem, it could be a sign that your memory card is wearing out. Do you have a second memory card? If not, I suggest getting one. Either way, put one card in each slot, and go into the browser. Copy the Guitar Hero saves over to the other card, then put that card in slot 1 and see if it works. If it does, I suggest copying all your saved games over to the new card, and throwing the old one out before you lose any save games permanently.

What do you mean by 'installed' guitar hero 3? 360's don't have separate video cards. Please re-phrase the question!
