Acer aspire 4378Z, intel pentuum dual core 2.13ghz is the laptop. It has only 2 of RAM. It is 5 years old. I donot have much softwares installed. and not much runs on the startup. No viruses, boaltwares or malwares. even if i install new os with whole harddrive format, it runs ok for about 1 week and then it becomes slow as ever. slowness: when i click on 'my computer' it starts after 30 seconds or so, with not responding and the mouse cursor loading you can imagine how painful it would be. Here is the resource monitor which shows only 958 MB physical memory used and 770 MB available.

resource monitor

CPU usage is only 10% in average and 50% max. frequency.What i can see in larger number is 100% highest active time in disk activity and 346571 MB disk space available. what actually is slowing down my laptop performance?

  • Having system memory free doesn't make a system faster. A "slow computer" indicates your CPU usage is high. – Ramhound Aug 30 '16 at 4:14

  • High disk usage can slow a computer down too. It has for me at least. – Tim G. Aug 30 '16 at 4:20
  • disk space is almost all free. – Steve Aug 30 '16 at 4:26
  • As I said your performance problems are not memory related – Ramhound Aug 30 '16 at 11:11

If there is any Hyper-v installed and running in background will also result in slow running of your computer.

Please do as mentioned below:-

(1) Try to stop unnecessary services which is the root cause of consuming memory.

(2) Go to system properties - Advanced - below performance Settings. Uncheck all visual settings.

I hope this will help you do away with the problem.

  • I have already done these two steps. – Steve Aug 30 '16 at 12:03
