PC Lagging when watching films and playing games

[tomatoey2]

Hi

I have been getting audio and screen tearing issues while streaming video online. I have no idea what the issue is. The videos I try to watch sound like a video that has been slowed down a lot to make that weird robotic noise. I have also started to notice the problem in games, the most noticeable being in Arma 2 where every 20-30 minutes the game lags about and freezes for no reason. I also get the lagging issue a bit on my desktop as my mouse lags about the screen.

Do I need to change a part like a CPU or Motherboard?

could be buffering due to internet but if you know its the pc too slow then try a different graphics card and maybe some more ram (dont forget clean the dust from your pc fans etc

Well as we don't know squat about your computer or anything else, and the answer can be ANYTHING from networking issues (Mom stop watching Netflix! I am trying to game!) to your system has a lovely 3,472 Malware infections. So let's do some basics first to make sure nothing else is 'getting in the way.

Download Speccy and copy the first tab here to show us your system

Download Malwarebytes and do a FULL (it is on quick as default) Scan, repeat till system is cleaned.

Remove any Antivirus you have (Microsoft Security Essentials doesn't work, and many whom have Norton keep finding it is interfering with program fully working by blocking different parts) and install either Avira, Comodo or AVG from www.filehippo.com (both FREE and top rated successful protection by two independent labs). Again do a full scan till clean.

Run Windows Update and make sure ALL patches and OPTIONALs (except BING) are installed.

Download and run SlimDrivers to ensure all drivers are up to date.

Tell us the results of all this, 90% of the time these resolve the issues for people posting here.
