I have a 60gb Launch PS3 with Kmeaw 3.55 installed and upgraded 750gb hdd. Everything has been fine till today i was playing gran turismo 5 and when i wanted to switch games i tried to exit back to the XMB and it froze at that screen so i held the power button down till it turned off. Now every time i turn it on the xmb glitches and it freezes and sometimes i dont get any signal at all in the hdmi channel. I dont have the ylod so i dont know whats going on. The only latest thing ive done was install the 3.60 spoof last night which was working fine so i dont know if that has anything to do with it. Any suggestions?
