I have ps3 80gb FAT bought on september 2009. recently it started giving problems, it boots up fine and game also loads fine. but when i put some graphic intensive game it works for some time and then i get 3 beep and red light keeps flashing. it could not be heat cos it happens when i turn on the system first thing in morning. i thought it was the HDD and got a new 500 GB HDD, but still same issue. i have done restore, rebuild etc etc..it is very random, i was playing tekken for an hour and it worked great. it plays movies fine too.but when i play graphic intensive game it failes, like uncharted, TLOU, killzone etc etc..i heard if its ylod it wont boot up..so please help me get some solution.
