Time after time, as you add more and more programs on your PC, they are automatically and quietly adding themselves into your Windows start-up folder or even on a hidden area of your Windows star-up system without ask an agreement of you. Therefore, the more programs load on your PC start-up, the slower does your PC start up. Therefore, you should limit the number of start-up programs, which will considerably fix slow startup of your slow running PC.
2. Improperly BIOS setting
Moreover, the improperly BIOS settings can cause a slow running PC. Normally, the BIOS settings are quite universal, while others can be found on only the systems made with one type of BIOS or made by one manufacturer. This section lists the most common settings that are used in modern PCs, with full explanations as to what they are and how to set them.
3. Bloated windows registry
People tend to install and remove many programs now and then, and their Windows registry becomes cluttered with redundant data with time.

Slow running pc for the hardware cause
Apart from software problems like startup overload or bloated registry, there are also a number of hardware issues that can cause a slow running PC. And the most common cause among them is low memory (RAM).
1. Insufficient memory
RAM is primarily responsible for your slow PC performance. Nowadays, the operating systems and applications require more and more capacities of PC memory, this is especially true fo the fantastic visual effects of hot Windows 7. Memory upgrade is an effecctive method for you to fix slow running PC and increase PC performance. However, if your PC RAM is already at the maximum that the motherboard can support but PC is still running slow, you may need to buy a new motherboard with higher RAM support.

After a long-time use, the files on your PC can be scattered over your hard drive that means the hard drive is badly fragmented and it takes longer and longer for system to search file. Defragmenting hard drive can speed up system response and thus fix slow running PC. Luckily, Windows offers a built-in tool to help you with hard drive fragmentations:
- Step 1: Double-click My Computer
- Step 2: Right click C drive (usually C) on the pop-out window, and then click properties
- Step 3: Select Tools tab and choose the Defragment Now option and follow the step by step instructions.
3. For the CPU problem
1> CPU running in low power mode
You might be running your CPU in low power mode which will reduce the clock speed. So, just check the BIOS setting or the power settings in the windows control panel for this.2> CPU is too hot
You CPU might be overheating and then throttling down to a slow speed, especially on summer days. So, please check your fans, heat sinks and CPU temperature. Always clean out any dust to prevent the fan outlets to be obstructed.Part 3:

Spyware, viruses and other mal-ware are another reason for a slow running PC. As virus is notoriously known to eat up a lot of system resource, your PC will easily slow down.
