Please review the following guidelines carefully to better help you understand what is involved in installing a mainboard. If you do not understand the terminology or are not comfortable attempting the installation, a Positronic Service Technician can install your mainboard / CPU for a reasonable charge. Due to limited staffing, we do not provide any phone support!
Guidelines for installing a NEW mainboard into a NEW case.
PREPARATION: clean flat surface, i.e. kitchen table, grounded electrical outlet/surge suppressor, Philips #2 screwdriver, case/mainboard mounting screws/standoffs (included with a new case).
- Before installing the mainboard into the case:
- Read mainboard manual for any precautions and installation tips.
- Discharge static electricity by touching bare metal, i.e. inside of case.
- Place mainboard on table. Avoid touching electrical traces (handle mainboard by the edges).
- CPU handle CPU by edge don’t touch contacts. If present, remove covering from bottom of heatsink!
• Place CPU into socket of mainboard and mount heatsink / fan. When mounting the fan/heatsink, do not use any tool that can slip when force is applied! Always put on heatsink before applying power to prevent overheating of CPU. For Socket 775 CPU, make sure all 4 heatsink retaining clips are firmly in (turn over motherboard and visually verify). For Athlon 64 CPU’s, do not use a heavy thermal paste as it will bond to CPU and cause CPU to pull out of socket when removing.
- • Remove memory from container avoid touching electrical contacts (handle by edge) and install. Be sure memory fully locks into place (review manual for location of memory slot 1).
- • Review the manual for any jumper settings that need to be changed. Check the CMOS jumper (if there is one) and be sure it is set to NORMAL.
- Open up case and do the following:
• Install ATX cover; remove punch-outs for speaker/mic/joystick/LAN if needed.
• Determine which PCI/ISA/AGP add-on cards will stick out the back of the case and remove case backplate covers.
• Determine which front bays will be used for floppy/CD-ROM/DVD/CDRW and remove covers.
• If applicable, install case feet to bottom of case.
- Hold mainboard over mounting holes to determine which mounting holes are to be used.
- Take out any STANDOFF's that do not line up with the mainboard mounting holes to prevent shorting out the mainboard. (Standoff's are any metal/plastic riser that the mainboard mounts onto. Metal Standoffs that do not line up with a mounting hole and touch the mainboard circuitry could cause irreparable damage).
- Install STANDOFF's (either metal or plastic) into each hole that lines up with the mainboard mounting hole.
- Mount the mainboard on the standoffs (to prevent damage make sure there are standoffs for every hold, and, that screw heads do not touch any part of mainboard circuitry. NOTE: There are 2 thread sizes, use the correct screw otherwise the screw may fall out. Do not over-tighten or mainboard may fracture!
- Install Power connector (ATX power supply can only mount one way be sure to press firmly down until it clips in place. If present, install 2x2 (or 2x8) power connector or system may not boot up.
- If video is not integrated, install Video Card. Note-make sure video card is fully seated into slot otherwise may not boot.
- Connect the Power Switch wire from the case to the mainboard connector see manual for location.
- Hook up the monitor, keyboard, and mouse. Plug in the A/C power cord and switch on the power supply (back of case though not all ATX power supplies have a switch), and, push the Power button on the front of the case.
- Does it boot up? If so Congratulations! Now install harddrive/floppy/CD-ROM and other components. Note: if PS2 Keyboard & Mouse are plugged in backward the computer may not boot up.
