10 Reasons Why Computer Running Slow?

There are reasons for a slow computer and any one of them could result in a crash and Blue Screen of Death (BSOD). A slowdown usually occurs over a period of time. Unless you are on dial-up that is slow to begin with and have less than 512MB of RAM, that too can be a major issue. Below are the top 10 reasons why computer running slow.

Startup Overload

  • The more programs you have that are loading at startup, the slower the startup.
  • Remove the programs you do not want or are not necessary to be starting at boot-up.
  • Clean up PC with below steps:
    Step 1: Update Windows.
    Step 2: Detect and repair disk error.
    Step 3: Disk Cleanup.

Spyware

  • These are malicious programs that stealthily embed themselves into your software.
  • They are installed in your software without your knowledge, especially through email.
  • These must be removed from your computer before they cause damage to your operating system and applications.

Registry

  • If your registry is corrupted or bloated, there could be a BSOD in your future.
  • Corruption or overload can cause:
    Performance problems
    Slow windows startup
    Extremely slow shutdowns
    A general disruption of system processing

Badly Fragmented Hard Drive

  • Over time, your computer files can be scattered over your hard drive; this is called fragmentation and causes file searches to be slower than usual.
  • Disk Defragmenter reduces data access time and allows storage to be used more efficiently.

Poor Security Software

  • A lot of security programs are bloated with software and demand a great deal of system resource and memory.
  • The constant surveillance of your system for malicious programs can cause your system to get sluggish.

Page File

  • Windows page file is a temporary source of memory used by the system in processing functions.
  • If the page file is too small, your operating system will not have enough room to move.
  • The result will be poor performance and error messages.

Too many Windows and Temporary Files

  • Your hard drive could be crammed with many useless files left over from re-installs and just general use.

Viruses

  • A bi-directional firewall and a good and reliable up-to-date antivirus programs should protect you.

Common Hardware Problems

  • If your hard drive is not working properly:
    Ensure that all cables are properly attached.
    Try for a system restore.
  • Undoing disk drive failures:
    Use System Disk to restore system
    Reboot your system with a backup disk.

Overheating

  • If heat gets high enough, devices may fail to function or suffer permanent damage.
  • Many computers are designed to automatically shutdown at a certain temperature and prevent the CPU from suffering permanent damage.
