Reason #1: Your computer has been running without a reboot for a long time.
What is a boot?
Is it the same start and restart process? There are many explanations, definitions and plain absurdities. Some of the valid technical definitions are difficult to digest for someone who is not involved in IT. I’m going to give you super easy responses.
Boot and reboot are first and foremost the same as start and reboot. Just “technically inclined” a sentence.
The User: Boot / Start means for you what it means when you turn your computer on after a while.
Reboot / Restart is when your computer is already running and you decide to reboot again manually.
When you just push the power button, Cold Reboot / Cold Restart is complete until the computer is switched off.
Warm reboot / warm reboot is when you navigate manually from the taskbar to the reboot option.
What does this mean to your machine: The Boot / Start process loads an operating system from the powerful state and starts the initial processes.
Restarting is usually necessary after activities affecting the functionality of: installing, uninstalling, implementing Windows, etc. make changes to the registry of the PC and then the PC with new registry entries is running after rebooting Windows. (It’s not necessarily the same as a Reset, so it may not be possible to reload the BIOS data.)
What about slow computers?
It’s all about organizational skills and discipline. Consider this: very few of the software installations and updates do not require restarting, while others do –and often (in particular, Adobe drives me a little insane with their updates.) Some changes require a reset-force and others just “request” a restart versus later restart. And let’s be honest, sometimes users like you and me brush it off, for we’re eager beavers. We have things to do, emails to send and want to save time now, which means starting the computer later…. In the meantime, there are some unfinished businesses within the PC, especially when several updates, patches, and ignored restart requests are mounted.
We must remember that all the previously mentioned activities (installation, deinstallation, etc.) will be rebooted and restarted. It will make the PC clear its cache, clear the RAM (Random Access Memory), make the PC read a new registry, “specify” your computer, to store data correctly.
Practical advice: Do not shut down your computer arbitrarily from the power supply. Use cold reboot only if anything else fails–the main cause of disc corruption is incorrect shutdown and should not be used. Carry out a Warm Reboot–Go to Start > Turn your computer off > Reboot. If you want to be super safe you go to Start > Turn off your computer > Turn off, and Boot your computer manually after 10-20 seconds.
Reason #2: Not enough space to free hard drive space Free disk space is just the amount of space to which you can write and which is not in use on the hard drive. Although free space is used to store files and data, it also allows swap file space and virtual memory needed for the programs, such as temporary file creation.
Practical advice: Make sure the space on the free hard drive is at least 20%, and if possible, increase.
How to determine the amount of hard disk space available (Windows).
Reason #3: Corrupt or fragmented hard drive There are several causes for a hard drive to be corrupt. Free space increases on your hard disk (Microsoft Support). The most evident is an incorrect shutdown. Many of us don’t care and wonder what could go wrong with a wrong shutdown. But the truth is that the sole reason for the corruption of hard drives is still a sudden switching off the computer’s power supply. Again, consider the situation, you have problems with one of your hard drives and it is likely that this will be corrupted. Perhaps the reason is a computer virus, but a corrupted drive scan can complicate the recovery process only later. Avoid scanning a corrupted hard drive on your computer. Let’s get a little more into the detail. When we first format our hard disk, we choose one file system, FAT or NTFS. Naturally, you will use ext1, ext2, ext3, etc if you are using Linux. Consider that you have selected the FAT 32 format while formatting your hard disk.
The FAT (File Allocation Table) is nothing other than a database stored on your system with each file’s respective address. A corrupted disk drive may just mean that your system’s FAT has been damaged so that the computer processor can not access the files you want.
Practical advice: diagnose your hard drive and repair it. (Note, don’t do it yourself if you don’t know the process below. Ask a IT technology professional to help).
Run ScanDisk or something similar to verify that the hard drive of the computer has nothing physically wrong.
Run Defrag to make sure the data is arranged in the best order possible.
Reason #4: Too many background programs Delete or deactivate any start-up programs that start automatically every time you boot your computer. If you have a computer security tool, malware and spyware protection or an antivirus scanner, set it to not scan your computer in the background. Often when these programs start scanning the computer, the overall performance of your computer can be reduced.
Practical advice: To see which programs run in the background and how much CPU and memory they use Open Task Manager. Set a timetable to run your security and other programs that require the hard drive scanning if you have the lowest computer activity.
Reason #5: Your computer is infected with viruses or malware You need to scan your PC if you believe your computer has been infected (read our Top 10 Computer Virus Symptoms Checklist). Spyware and other malware are today a major cause of many computer problems, including a computer that is slow. Although an antivirus scanner is installed on the computer, we recommend that you run a malware scan on your computer.
Practical advice: Try to scan your computer for malware in free or trial antivirus versions.
Reason #6: Hardware conflict and outdated drivers Hardware conflicts arise when two devices, such as an IRQ or the memory address, try to use the same resource and cause an error. For example, if a computer hardware device shares the same IO port as another device that leads to a hardware conflict. In modern hardware, conflicts are less common because each hardware device installed on a user’s computer is managed via plug-n-play (PnP).
Practical advice: Use the Device Manager for your computer to check that there are no hardware disputes on your computer and to resolve your problems if necessary. If you have problems, solve them as they may be the cause of your problem: step 1. Select System from top of the list and click Properties. Open the Device Manager.
Step 2. From the Resource List, you should be able to determine which devices are used, and which devices cause a conflict. If you determine the conflict, refer to the manual for the device for information on changing the configuration to resolve the conflict. If a problem is solved, the next step is not necessary, otherwise: step 3. Remove or disconnect from your computer all the non-vital devices, like a sound card or CD-ROM, except one that does not work. If the device still does not work, a key piece of hardware, for example, a motherboard, may be broken or conflicting.
Step 4. It can also be a driver problem if the problem is not solved. If the driver is faulty or outdated, computer communication with a particular hardware can interfere. You could contact your computer / device manufacturer for the latest drivers–most of them can be downloaded free of charge. Even if your older driver is not defective, a new driver can improve the performance of your entire device.
If the problem appears to be fixed, start adding devices one by one. Hopefully the problem won’t reappear; if so, reconfigure this device to eliminate the conflict, as in step 2 above.
Reason #7: Your Windows version (or any platform you may use) or other software is outdated.
Make sure you have all the latest Windows updates on your computer installed.
When your computer is slow on the Internet, also make sure that all browser plug-ins are up to date.

The electric current that passes through the circuits of a CPU constantly generates heat. (Your CPU’s temperature depends on the model and its use.) Make sure your computer and processor do not overheat. Excessive heat can cause a significant drop in computer performance, with some processors automatically lowering the processor speed to help compensate for the heat problems.
In modern processors the optimal temperature range of a CPU usually ranges from 70 to 90 degrees Celsius. The smaller the computer, the higher it is. Some computers can suffer irreparable damage without a fan. Make sure your computer fan isn’t faulty, in addition to your regular power supply fan, you can add more fans.
Practical advice: CPU temperature monitoring software is included in the majority of motherboard manufacturers. If you don’t know if you have one, contact the manufacturer of your computer.
