hello and welcome nijjhar now mate have you run any scans on the machine?? if not then I would suggest you try these first
SFC /SCANNOW Command - System File Checker
Disk Check < if necessary include the /f and /r in the command line as per Option2 (if you are going to use the /r switch there is no need for the /f switch)
Run these in safe mode and the sfc often best run for two to three runs – you can leave out the /r switch in ckdsk if you feel it not necessary
if no fix then these
SUPERAntiSpyware | Remove Malware | Remove Spyware - AntiMalware, AntiSpyware, AntiAdware!
Malwarebytes | Malwarebytes Premium
AdwCleaner Download
ADW download from bleeping computer delete any rubbish found with the malware scans
(NB If you are running Kaspersky as the main AV then it might need disabling it when trying ADW because it does not like it at times)
The webcam I am assuming the driver for it is up to date? and also the drivers for whatever pointing device you are using ? external mouse?? or touchpad?
The otehr thing is I see from a Google that it is an older machine and thta it came with McAfee software - did you get rid of the AV if not then do so but use the correct removal tool

There was also the Microsoft Office program included on the machine when it wa made did you buy the full version if not if it does not work then uninstall it and a good replacement if you wnat a word processor is this
LibreOffice Fresh | LibreOffice - Free Office Suite - Fun Project - Fantastic People very much like the Microsoft suite and really easy to use - I use nothing else now because it is free (one can donate) and I begrudge having to buy Microsoft stuff when I have got the suite and cannot use it because of the number of installs they allow.
Lastly can I ask why the odd amount of RAM you have in that machine - 5GB seems an odd number to me but that may be your choice of course.
