Is your computer freezing or responding slowly? Don’t worry — it’s one of the most common issues faced by desktop and laptop users. In most cases, it’s caused by hardware wear, dust, or system overload. Let’s go through the main reasons and how our expert team at Crescent Computer can fix them.
1. Overheating or Dust Build-up
When your computer overheats, it can cause lag or system crashes. Dust accumulation inside fans or vents restricts airflow. We provide professional cleaning services and thermal paste replacement to ensure smooth cooling.
2. Faulty RAM or Hard Drive
Bad RAM or a failing hard drive can result in system hangs or blue screen errors. We perform detailed hardware diagnostics and offer genuine replacements for HDD, SSD, or RAM modules.
3. Corrupt System Files
Improper shutdowns or power failures can damage Windows system files. Our technicians restore or reinstall OS files and back up your important data safely.
4. Too Many Startup Programs
Programs that automatically run at startup can slow your PC drastically. We optimize startup settings and remove unnecessary background apps to improve boot speed.
5. Outdated Drivers
Old or incompatible drivers often cause performance issues. We update and install proper drivers to keep your hardware running smoothly.
6. Old Thermal Paste or Cooling Issues
Thermal paste between the CPU and heatsink can dry out, causing high temperatures. Our service includes thermal maintenance to reduce heat and improve longevity.
7. Virus or Malware Infection
Hidden malware can make your system unstable. Crescent Computer offers deep virus scanning and removal with optimized security settings.
