I have memory issues that are causing lag spikes, I have 8 GB of RAM (2x4 in dual channel). I've already freshly installed windows 10 over 3 times, I have updated my EFI to the latest version, I did serveral virus scans, I changed the memory sticks from my other computer to this one.. But the weird thing is that there are no applications in task manager that are using a lot of memory. My google chrome is at 50 MB and it says my memory is at 100%. On my other pc I have applications running that are using like 300 MB and there my memory is only getting used for 40%. I realy don't know what the problem is, Maybe someone can help.. Thanks
