I'm facing this problem from two weeks. when i turn on my PC it boots up fast as always it did the problem comes when i try to open Programs(applications) either it shows as loading or it opens and stops responding and after around 5 mins after receiving not responding dialog and restarting the program it works without any problem so to solve this problem i did a little homework : i checked ram, processor, HDD, Graphic card everything worked fine i also deleted unwanted programs fine tuned everything but problem existed and continued. Today i found out that i faced this problem when i turned on PC with internet modem turned on and the problem existed later i tried it by keeping the internet modem turned off at the start up problem no longer existed. I also tried turning PC first and after start up i turned on internet modem i did not find the problem. I only face not responding programs when i turn on my PC with internet modem turned On.
please help me out i do not want to format my PC.
Try disabling all startup programs.
I have Kaspersky scanned with it no problems were found. I have disabled all programs at startup except necessary programs like Kaspersky using TuneUp Utilities. also ran CHKDSK, SFC /SCANNOW, nothing helped
