Why buy from ES Computer Services

All computer chips are produced in volume on large silicon wafers. Individual chips are trimmed from the wafer and used to make components; processors, graphics cards, motherboard chipsets all result from this process.

Manufacturers must test every single chip in order to determine its capabilities. Some chips simply run faster or perform better than others. Higher performing chips make up the best retail components, while the slower performers are typically sold in bulk to the large Original Equipment Manufacturers (OEMs) like Dell, HP, Compaq, IBM and Packard Bell the behemoths, who use these components in the majority of their systems.

What does this mean for you? Well, most larger OEM's use white box parts in almost all of their systems, creating PCs that will perform slower and fail earlier than systems built with retail components.

ES Computer Services is different. Our company uses many full retail graded parts in its systems. Most motherboards, CPUs, video cards, RAM, sound cards, optical drives, and other performance components are boxed or retail grade to ensure the highest level of quality and reliability attainable. Combined with a stringent assembly process, these superior components mean that you get the best performing system possible for your money.


Assembly Process

ES Computer Services, ultra-performance computer systems result from the rigorous assembly procedures developed to produce each system. From start to finish, each system is individually hand-crafted by certified technicians. Once completed, the next step is a warrant of fitness test checking everything from the physical appearance of your system to its software, performance, and usability. After passing a 20 point checklist and diagnostic software testing, each system gets examined one more time before shipping out to the customer. The result is a high quality system that performs beyond your expectations.

Here's a walk through of our assembly process.

  • One of our trained and certified technicians gathers the pre-tested components kit required for each system order.

  • The case's side panel is removed and stored inside the cardboard container along with the power cord and any other case accessories.

  • Any additional case fans are installed in the proper vent areas. The drive slot covers are removed and placed inside the box for the customer's future use.

  • The nuts for the motherboard screws are installed in the correct configuration to align with the chosen motherboard.

  • Any concealed wiring to be done under the motherboard is taped down to hold the wires in place while it is set in place.

  • The motherboard receives the CPU and RAM prior to installation to avoid stress and possible damage.

  • The motherboard is placed inside the case.

  • The power cable, case fan cable, CPU fan cable, power on button, reset button, internal speaker, and all case LED light cables are connected.

  • The video card is placed in its proper slot. The screws are securely tightened by hand to avoid over-tightening.

  • A power cable, keyboard, and monitor are attached to the proper connectors for testing purposes.

  • The system is started and checks are made for the power supply, fan, the case fan, and the CPU fan.

  • As the system begins to boot, we check the display for proper RAM count. We then launch the motherboard's BIOS interface.

  • The time and date are set and the proper CPU settings are made.

  • The changes to the BIOS are saved and the system is restarted to be sure the changes were accepted by the BIOS.

  • The system is then powered off and the power cable, keyboard, and monitor are disconnected.

  • The first optical drive is inserted in the top drive bay. Any additional devices are installed similarly.

  • The hard disk drive is installed closest to the bottom of the case to benefit from the coolest air possible.

  • Extra long drive cables are attached for each device, starting at the top and proceeding downward to prevent tangling.

  • The power supply connectors for each device are then inserted, starting at the bottom and working upward to prevent tangling.

  • Rubber bands are used temporarily to restrain extra cabling and allow for a clear view of the motherboard.

  • The motherboard is flashed with the latest BIOS available from the manufacturer's website.

  • The processor update is run to add important fixes, patches, and corrections to the fundamental interaction between the motherboard and processor. These steps can significantly reduce system errors and lockups.

  • The keyboard, monitor, power cord, and mouse are inserted and the system is powered up again.

  • The display is checked to ensure the system detects the installed drives.

  • The BIOS is set for boot sequence DVD-ROM, then Hard disk drive. Other settings are made for proper operation and the BIOS adjustments are saved, the system is restarted again.

  • The system reboots to our DVD and formats the hard drive before Windows® is copied to the drive and installed.

  • Windows is installed according to Microsoft's OEM scripts.

  • Any other necessary PCI cards are inserted one at a time (example: sound card, Wifi adapter). Each card is inserted and secured tightly before the system started and the latest drivers and software are installed.

  • Another restart ensures all systems are properly installed and functioning before the system is shut down again.

  • We make adjustments and tweaks to the motherboard BIOS and Windows settings to ensure peak performance.

  • Software is installed for system monitoring and management; settings for RAM management, video performance, and disk performance are optimized to work best for the customer's exact system.

  • The most recent software driver updates are downloaded from the appropriate vendor’s website and installed for peak performance.

  • Software may be installed as well as disk caching software for some hard drive models to further enhance performance.

  • Customer support information is placed on the computer for easy access to contact information.

  • Antivirus protection is also installed and the latest virus catalogue updated.

  • The rubber bands are removed from the SATA or SCSI cables. The cables are coiled loosely to prevent crimping the delicate internal wires and are tucked neatly out of view as much as possible.

  • Each cable receives one or two cable ties applied snugly to hold the cable in place. We make it easy to upgrade in the future.

  • The cables are pulled toward the sides of the case to allow proper air flow through the centre of the case for cooling. All other cables are similarly secured with hand tightened cable ties and all extra tie length is cut and removed.

  • The case cables are braided together before being tied down. The case cover is not installed until final overnight testing.

  • An assembly technician tests the system with our 20 point checklist, then the system receive a rigorous battery of diagnostic software testing and benchmarking to ensure proper performance. Then our technician begins the physical inspection.

  • Our checklist runs the gamut from loose or missing screws to tight cable connections to audio cable tie downs.

  • The technician makes numerous checks during assembly, then a quality control technician checks to ensure nothing was overlooked in the process.

  • Every screw must be re-tightened and every cable must be securely strapped before the cover is installed.

  • Every system receives a diagnostic test to ensure all subsystems are properly installed.

  • The case cover is re-installed for all other tests to make sure the case allows proper air flow and minimal vibration during use.

  • With the case cover on, the system runs through as many as 10 cycles of thorough testing of every system resource for proper performance.

  • The system then is allowed to run overnight on a test bench. The system monitor checks CPU temperature constantly to watch for signs of overheating during extended use.

  • After running overnight, the system must properly wake up and restore itself from suspended sleep.

  • Software is installed to perform a variety of benchmark performance tests. These tests provide information about the overall speed of the system and help diagnose specific problems.

  • Benchmark results are compared against systems from other manufacturers as well other in-house PCs.

  • A variety of basic tests, including DVD functionality, are performed.

  • Any additional software that is ordered with the system may be pre-installed and run to check for proper launch and function.

  • The DVD drive is checked for proper eject operation as well as any abnormalities.

  • Just prior to shut down and packaging, every system is restarted and tested to see exactly what the customer will experience when they receive the system.

  • We deliver directly to you and set up the new system to your expectations, this includes setting up of your email, internet connection and transferring of data from your old computer.

Each PC goes through the above procedure, but there are dozens of unique optimizations and performance tweaks we make along the way to accommodate a particular setup. Our unique assembly process is just one of the reasons why you get more for your money with ES Computer Services.
