Your Computer Lags When Playing Games/Watching Video/Typing? – Solved

It must be quite vexed and dysphoric if your computer lags when you are playing games, right? I have such an experience.

One month ago, when I was playing the Grand Theft Auto, my operation would delay one or more seconds randomly, which nearly drove me insane. As a result, the mouse was broken due to force. Have you ever encountered similar situations?

Actually, our computer might lag in other time apart from playing games. In this post, we picked out 4 commonly seen lag situations, including lags when we play games, lags when we watch video, lags when we type, and lags every few minutes.

Now, let's begin.

My Computer Lags When Playing Games

play games

When RAM and CPU are in heavy burden, your computer would delay your operations when you are playing games. To fix this kind of lag, please close all unnecessary programs. However, if the lag still exists, take upgrading hardware components affecting game experience into consideration, including:

  • Graphics Card: it is the most crucial part for gaming experience, because both 3D graphics rendering and calculating in-game physics are done on the graphics card. Playing games on computers with low level graphics card, your computer is very likely to lag. So upgrade it if the current one is old.

  • Hard Drive: the speed of your hard drive determines loading times. If you are playing games on computers which are still using traditional mechanical hard disk, your computer would lag especially when you are playing games fairly demanding for speed. For this reason, we suggest upgrading HDD to SSD, which would dramatically speed up your gaming speed if you configure SSD properly.

    There are many ways to help you get best performance from solid state drive, and you can find step-by-step tutorials from this post.

  • RAM: when there is no enough RAM, the game will constantly be reading data from your hard drive rather than RAM, thus slowing down your computer or even making your operations delayed. Are you still using 2GB or 4GB RAM? It's time to add more.

  • CPU: when CPU is running at 90% or more, your games would be slow. So just upgarde it if necessary and possible.

Tip: you can type dxdiag in Search box or cmd to view details of your hardware configurations.

But how to do the upgrade? You can ask technicians for help, but it may cost extra money. Instead, you can do it on your own by following instructions found from the internet. In this post, we only focus on upgrading HDD to SSD, because it is the only upgrade related to data transferring.

How to Upgrade HDD to SSD

For desktop users:


Please take the following steps:

Step 1: Mount the SSD to your computer via SATA.
Most motherboards for desktops are configured with multiple SATA slots, so you can connect the SSD very easily.
Step 2. Migrate Windows from HDD to SSD and reinstall games on SSD.
Of course, you can choose to install games on SSD only, but why not run Windows on SSD to speed up your computer when there is such an excellent hard disk? In addition, if your games are installed on boot partition (the C drive most of the time), migrating Windows will also transfer your games to SSD (not simply copy games), which makes it possile to play games on SSD without reinstallation.

Kindly reminder: the SSD should have enough capacity to hold contents of partitions required to boot Windows if you are planning to migrate system to SSD. If no enough space, just install your games on it.

To migrate Windows, you need to download MiniTool Partition Wizard which is free for Windows non-server users.

After successful installation, please start and launch the program to get the main interface:

migrate Windows to SSD choose the exact function

Here, please choose the feature "Migrate OS to SSD/HD Wizard" on the left side.

migrate Windows to SSD select ssd

Then, select the SSD to transfer Windows to and click "Next".

jg Warning: all data saved on SSD will be erased during the process of migrating, so please backup important ones at first.

migrate Windows to SSD choose copy method

In above interface, we can preview layout of SSD. If you are dissatisfied with it, there are 3 copy options available. Just choose the one you desire and click "Next" to get a boot note.

migrate Windows to SSD boot note

Just read the note and click "Finish" to continue.

migrate Windows to SSD apply changes

At last, click "Apply" button to make all changes performed. Then, you'll be prompted to restart computer. Just do as it tells, and then all operations will be done in boot mode.

Once all changes are performed completely, your computer will reboot. If you are booting Windows from MBR disk, please restart your computer and set the SSD as the first boot device in BIOS, and then your computer will boot from SSD. Users booting Windows from GPT disk can skip this step.

However, if your games aren't installed on C drive, please reinstall them on SSD. Then, play games to see whether your computer still lags.

For laptop users:


It is relatively difficult for laptop users to upgrade SSD, because they need to take out HDD from laptop, then clone HDD to SDD, and mount SSD to laptop. But lucikly, we have a post showing how to do the upgrade. Please see How to Upgrade Laptop's HDD to SSD to get details.

Of course, if your computer stutters when you are playing online games, internet speed or connection speed is a big cause apart from hardware related issues.

Then, let's see the second lag situation.

My Computer Lags When Watching Videos

watch video

Watching online videos, consider the following 4 causes:

1.Poor network speed.
To fix this issue, you can switch to a lower definition, for example change High Definition to Standard Definition or 1080p to 720p.
Alternatively, you can also watch the video after downloading it or the buffer is completed. Or close programs that are useless but take up much bandwidth.

2.A huge number of people are watching the same video
Under this situation, see it later or download it to local disk.

3.No enough RAM
To help users better understand this issue, we will show how RAM impacts online video speed.

Files, programs, videos, and all other data we are using are loaded from hard disk but will be placed into RAM to deal with, since reading from RAM is much faster than reading from a hard drive. So, when we are seeing an online video, the video will be placed into RAM and then play. However, if there is no enough RAM to hold contents of the video, system will move some of the data from RAM back to hard disk, placing it in the page file, so as to release space to hold contents of the video, and then play, then move data to hard disk, and save contents of the video and play, continuously. As a result, your computer lags.

To get rid of the computer, just close all unnecessary processes, including programs, web pages, and so on. Of course, to upgrade RAM is a good solution.

4.Browser is out of date
Just update your browser to the latest version.

Watching local videos (videos that have been downloaded to local disk), consider these causes:

1.Your video player is old.
For this case, try updating your player to the latest version or download other players.

2.The drive saving your videos is fragmented.
When the video is stored to clusters that are not continuous, it will cost more time to read all contents of the video. To deal with this situation, defrag the drive with Windows built-in Disk Defragmenter. See Defrag Hard Disk to get detailed steps.

Alternatively, you can upgrade HDD to SSD which reads data in an amzingly fast speed. For how to upgrade, please see How to Upgrade HDD to SSD.

My Computer Lags When Typing


When there is a delay between typing characters on the keyboard and the characters showing up on the screen, most of you would feel annoyed. Here, we are going to show users possible causes as well as solutions.

1.You are now using an integrated or low level Graphics Card
With poor Graphics Card, your computer will lag when you are doing most operations, including typing characters. For this issue, the best solution is to upgrade your Graphics Card. However, if you have this problem just all of a sudden, see the second cause.

2.CPU and RAM are nearly used up.
When CPU or RAM is used at more than 90%, your computer is likely to lag when you are typing. Please rrefer to the following steps to review how much CPU and RAM are used.
Please type taskmgr in Search box, and then run this program as asministrator to see how much memory and CPU is used under Performance tab.

RAM is nearly used up

If there are so many resources consumed, please close all unnecessary programs from Programs tab or end useless processes from Processes tab.

3.Your computer might be infected with virus.
Sometimes, even if we just run few processes, our CPU and RAM might be running out of space. Under this situation, take virus infection into consideration.

Bwsering unknown web sites or downloading unknown files/programs/attachments could cause our computer to be infected with virus. Once a computer virus invades our computer, it will copy itselft continuously, which will definitely consume a lot of RAM, network bandwith or even CPU. As a result, your computer is very likely to run slow or stutter.

To clean virus completely, we suggest doing it in Safe Mode, which could remove malware that cannot be cleared in normal mode as well as furthest prevent virus from running. View the Post How to Use Safe Mode to Fix Your Windows PC to get steps to Enter Windows Safe Mode, and then launch your antivirus to clean virus.

Further reading:
Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started.

4.Your battery is the culprit – for some laptop users.
On the internet, I found a very strange situation: lots of laptop users complained that the battery causes their laptop to lag; once they take out the battery and power the laptop via the power cord, their laptop runs without any delay.

So, if you are using laptop and troubled by lag, just try this solution.

5.Your wireless keyboard generates the lag.
If you are using wireless keyboard, please change another keyboard to see whether it is due to keyboard issue. Sometimes, quality of wireless keyboard or distance between computer and keyboard influecen the speed.

If this is the case, use another keyboard or use the wireless keyboard beside the computer.

Now, let's see the last lag issue.

My Computer Lags Every Few Minutes

Compared with the former 3 lag situations, this one is not that commonly seen. And here we will show 3 possible causes.

Cause 1.Y our hard disk is set to "Sleep" in a specific time.
Firstly, let's see an example.
Hoods asked the following question on SevenForums:

Hi - lately there is some problem with my hard drives taking some time to react again after they've been quiet for a while. I have three drives, with my operating system from a SATA 3 and all my data on two 1TB SATA II drives. The delay occurs when accessing either drive. Once the drives have clicked in (it's an audible click) all is fine until after another period of them doing nothing. I am hoping this isn't a hardware issue. Is that likely??

Then, LittleJay gave the solution:

You could try going into Power Options in the Control Panel and then opening "Change Plan Settings". Once there, you can open "change advanced power settings" and under "hard disk" you can set the value to "0" minutes and see if that helps.

And finally Hoods picked this as the best answer sine this solved the problem.

The example shows setting hard disk to sleep will cause computer lag, but you can try setting it not to sleep or sleep after a very long time to solve the problem.

Cause 2. Graphics card driveris out of date.
View your computer or Video Card manufacturer's website to see whehter your computer is using the latest version of Graphics Card driver. If not, update the current one to the latest version.

Cause 3. Your Hard Disk Might Have Errors
When a hard disk is going to failing, your computer might stutter when you are visiting this disk. When there are errors on file system, your computer is also likely to lag. But you can download MiniTool MiniTool Partition Wizard Free Edition and use the Surface Test feature o test whehter there is bad sector on your hard disk, or use Check File System to detect and fix system errors.
