Smart Computing Article - You're Having Video Problems

If you have another graphics card, try installing it in the current graphics card’s place. If this doesn’t solve the problem, you may need to troubleshoot your graphics card. Refer to “Basic Troubleshooting: Graphics Cards” on page 82. Sometimes, components besides the monitor and graphics card can cause video problems. One common culprit is RAM. If the RAM modules in your system are improperly seated or have failed, your display won’t initialize and your computer will fail to boot. Shut down your computer, open the case, touch a metal part of the case to dissipate static electricity, and unplug the computer. The RAM modules are commonly located to the right of the processor. To remove the modules, press the clips at either end of each module down. The module should pop out of the slot. Examine the modules for visible damage, remove dust with a clean, dry cloth, and reinsert them if they appear undamaged. Make sure the modules are oriented in the slot correctly (the slots are keyed to prevent improper orientation) and then press the modules firmly into the slots and allow the clips to snap into place. Close the case, plug in the PC, and restart it. If the problem persists, you may need to troubleshoot your RAM. Refer to “Basic Troubleshooting: RAM” on page 98. If you’ve attempted all the above but still don’t see anything on the display, any number of your PC’s components may be causing your computer to fail to boot. Turn to the PC Components section of this issue to begin troubleshooting other possibilities, such as your PC’s ports (see “Basic Troubleshooting: Ports” on page 91), power supply (see “Basic Troubleshooting: Power Supplies” on page 93),
