Hello. I have a Packard Bell iextreme M5722, with 6GB of RAM and with an NVIDIA GeForce GT 220. I do not have much installed on my machine and run AVG antivirus. I am getting periodic (like a couple of times an hour) performance issues, where by if I am connected to the internet, it just hangs (I am pretty sure it is not my connection as all my other devices work fine) or if I am using an application or playing a game (a five year old game no less) the performance almost grinds to a halt. I have tried to get to the bottom of this via the resource monitor but to no avail - to be honest I don't really know what I am looking at. I assume there must be some kind of scheduled job that runs and kills my machine but I cannot identify it. If I turn off an on again it usually runs fine for a bit and then grinds again. Do you have any suggestions for how I identify the fault and fix this? Many thanks!
