Chaser LED IC Help

I built this circuit and I am having problems with it. Can I get some advise?
The problem I am having is that when I hook up power to the circuit the leds are chasing. I put a transistor at pin 4 on the 555 ic that turns on with harddrive activity. (I think hd act. is 5v.) I thought that if there is no power to pin 4 the the 555 will not have a high output. If I do not have power at the transistor base, the 555 output is not high and the 4017 should not activate the leds..... so why are they on all the time?

PS. I used someone elses diagram and made calcs for my leds and added a transistor to switch Vs to pin 4 on 555. The original diag. had a on/off switch at dc battery.

Why exactly do you need the transistor? The pin wont draw alot of current so you can just directly connect it to the hard drive led wire.
and I think you would need a PNP transistor for this situation. I've already had BJT's in my microelectronics I class last semester, but they just focus on the theory behind it and not how to apply it.
