GHA "elite" controller shutsdown ps2 system

I just got the new wireless guitar hero aerosmith brand new. played it a few hours worked fine nothing wrong at all and had to leave soon after, went to plug it in tonite and it all but shut down my system--leaving the reset button light on but not the eject light, it wont eject, screen goes black and no signal through port to guitar. but when i shut off the ps2 and unplug the controller reciever, turn system back on with a different wireless controller(same game) it works fine......no idea whats goin on other then maybe my ps2 is runnin outta juice and need a new one? its a good 5 years old i think

heres what i got, the one that shutsdown my ps2: --ebay--
