i just made a CPU Over-Temp Detector / PSU Shutdown as a fail safe in case my pump fails according to the instructions on the procooling site.

here is my lay out for the board:

and here is the finished board:

the board sorta works when the green LED lights the Power-on signal passes through and when the red LED lights the Power-on signal is cut off. BUT the circuit won't fire and latch pins 2+3, 8+9 (cut circuit and light red LED) unless l push the reset switch, in which case no matter where i turn the pot. it will not reset and latch pins 3+4, 7+8 (connects power-on signal and lights green LED). what am i doing wrong

here is a list of the components that i used (scroll all the way down)
