Computer slowed down

  1. Last night my computer was running fine. Today it feels like it is slowed down. For exampe, when I went to play a certain game, that always ran fine on my computer with great FPS rates, now it is very laggy. However, what is strange, is that other games, that I tried seem fine.

    But I think it is something in the computer and not the game. I say this because my computer just generally feels slower. Games take a longer time to load than usual. Also when I drag the Internet Explorer broswer there is a small lag delay before it starts moving, I do not think I ever had that before. Just generally, it feels like there is some sort of lag issue on the computer.

    I had a similar problem like this in the past. I solved it by playing around with the AC adapter and my computer FPS rates were back to normal. It feels like a similar problem I had before but I am not sure what is causing it.

    I would first rule out software problems. Sounds like a malware/spyware problem.
    download and run http://www.malwarebytes.org/ and http://www.safer-networking.org/nl/mirrors/index.html .
    These are good tools to keep you pc free of such things. Also let you anti-virus run a scan if you don't have one check out http://www.avast.com/nl-be/index . a defragmentation of your drive may help also. If you still have problems after that get back to us.
    If it was a power issue make sure your cpu and gpu are running at full speed and not downclocked to save energy.

    Run Task Manager (right-click on Taskbar). Is you CPU usage at 100%? Check which process is using the most resources.

    1) No, it is not a spyware problem. I check my computer regularly, that I know for a fact is not an issue.

    2) My CPU usage is at either 0% or 1%. In the extreme case, when I ran GTA 4 on my computer (a very demanding game), which actually ran fine, the CPU usage was only 12%. I was able to minimize the game immediately and go to a different application without my computer slowing down.

    3) I think maybe there is a problem in my power supply for the laptop. I had a similar problem, just much more extreme, before when everything was running really slowly. I fixed it by moving around the power cord. I think that maybe there is a break in the power supply somewhere and my computer is not recieving maximum power which is slowing it down. How can I check if my ac adapter is fully functional.

    I solved the problem. Now everything runs smoothly at max FPS rates. Basically, when I unplugged my laptop it automatically set itself to consume low power to conserve energy. When I replugged the laptop it did not automatically raise itself to maximum power. Thus, my ac adapter was not supplying my laptop with maximum watt usage, but at minimum level. When I set the settings to use maximum watt usage everything is running fast and smooth.
