need advice on program hanging

Good day. I made a program which has 4 timers all of which works on interval of 1000

My problem is after few hours, this program hangs and so I cannot touch its menu or see whats in the gui.
I also used DoEvents on each timer hoping it will lessen the transaction in memory but this does not work.

What should I do so that my program dont hang?

I am thinking if winsock causes this program because I have this timer to check PC Ip adress.
