problems with 16F887: config or hardware

[keithv]

Here's the schematic. I'm using 5 switches to toggle 8 different LEDs on and off. The problem I'm having is that if I have 7 of the LEDs (any combination) on, the 8th LED resets everything. And if I have 5, 6, or 7 of the LEDs on, it will reset after a few seconds. Seems to work OK if I only have 4 or less LEDs on at one time. I'll post the code in just a second. It's on a different computer.

I'm not sure what I'm doing wrong here. Any help would be greatly appreciated.

nevermind. Figured it out. It was a hardware problem. I was using a dying battery. Switched over to DC adapter power supply and it works good.
