Slow down of computer is one of the most common issues faced by the user nowadays. There are many reasons due to which windows get slow down.
There are several causes for windows to slow down. If you can remember a time when your PC ran faster, it is most likely due to program build up over time. A lot of software, especially the kind that is downloaded, like to run “in the background”, meaning that every time you boot your system, it starts up. And this is not just Trojans or spyware, but “legit” software like QuickTime or Real Player. This inevitably leads to a slow computer.
Random access memory or RAM is a computer’s short-term memory. RAM stores bits of data from the hard drive that the processor needs to access quickly to run ongoing programs and processes. When processes cease, the RAM drops the unneeded data to make room for new demands. When you run many programs at the same time, the RAM can become full of data. When this occurs, the computer will slow down since it will be forced to wait for data from the hard drive periodically.
Multitasking is one of the main reasons that computers slow down. When you try to run several programs at once, it forces the CPU to carry out calculations for different purposes at the same time, which increases its workload, and can cause it to reach its peak operating speed. If the processor reaches 100 percent of its calculation speed, your computer will lag, as it must wait for more calculations to take place.
When a hard drive is near its total data capacity, it will run more sluggishly and take longer to access data. This translates into slower data transfer to your RAM, which means your computer will lag more when accessing programs and data files. Another problem with allowing a hard drive to fill up is that data become disorganized or “fragmented.” Fragmentation occurs when data for a specific file or program must be split up and saved on different sectors of a disk because there isn’t enough blank space to save it all on one contiguous sector.
Drivers are software packages that tell your computer how to use certain hardware devices. As time goes on, hardware makers release new drivers to optimize their devices for new programs and applications. If you fail to update your drivers to versions meant to handle more modern programs, your computer may run slower as a result.
Malware, viruses, Trojans, worms and spyware can negatively affect the performance of a computer. Malware is software that is programmed to infiltrate a computer system without the user’s consent. It causes damage to a computer network, a server or a stand-alone system. A virus is a computer program that spreads from file to file within a computer system and goes on to affect other computers.
A worm is a type of virus that is programmed to copy itself within a computer’s memory before going on to infect other machines. A Trojan Horse is malicious software under the guise of a security update. Trojans modify or destroy data by erasing the contents of a hard drive; Trojans also steal credit card numbers, passwords and other confidential information. Spyware is a program that collects web user information for advertisement and other purposes.
