Computer Repair and Upgrades

Computer Upgrades Lake Forest

SSD Drive

Sometimes a computer is not broken, but its performance can be improved. We offer upgrades to make the computer run better. Either Laptop or Desktop computers, as well as Mac computers, can be upgraded.

  1. Hard drive upgrade. Upgrade to a larger drive (up to 16TB for desktop and 2TB for laptop) or faster SSD (Solid State Drive)
  2. Ram Upgrade. Older Windows like Windows XP , Windows Vista and 32Bit Bit Windows 7, 8 or 10 need 4GB to perform at their best. We have old and new style RAM such as DDR, DDR2, DDR3, DDR4 styles in stock. For 64bit Windows 7, 8 or 10. We recommend 8 or 16GB for Office machines, and 16GB or 32GB for workstations and gaming computers.
  3. Video Card upgrade. Todays CPU are so powerful they do multiple duty. Many computers integrate the video processor with the CPU. Sometimes performance can be improved with a discrete video card, which will lower the power used by the CPU and hence the temperature, as well as provide a boost in processing graphics. This upgrade is primarily for desktops.
  4. Faster Wireless. Many wireless use 801B/N which is older technology. Today, a faster wireless is 801.A It is twice as fast as the B series. However, the router must be a dual Band type (the second band being the A type). We offer both the A band wireless receiver and routers.
