Irfan, after some 20 years debugging computer system problems, I can tell you with near 100% certainty, that the answer to your question:	
	"is the problem caused by HARDWARE or SOFTWARE?"

is YES, the problem is caused by Hardware or Software.

As to whether it is HW or SW in your case, only careful study of the system will tell.

Can you provide details (schematics, source code, etc) of your system?
