Ok an artist just brought me a a G5 duel 1.8 with 2 gigs of ram but the dang thing wont boot. All I get is the blue light blinking TWICE. Not three times. Im thinking bad PSU or Mobo. Any ideas guys? Please I need help on this one ASAP because I need to pull the HD to get a project off if this cant be fixed. Heres what Iv done so far. 1. Reset the board. 2. Rearranged the ram. 3. Replaced the ram. 4. Replaced the HD. What else can I do?
