After a minute has passed, press the power button repeatedly in order to drain the capacitors. Perform a power cycle by unplugging the power cable, turning the switch to the ‘0’ side and taking out the CMOS battery from the motherboard.

Short the PW SW pins with a metal screwdriver by touching the two pins in order to attempt to turn the PC on without the power button. Locate the PW SW/RES SW headers on the motherboard and reseat them. Reseat the 24-pin motherboard power cable (next to RAM) and the 4/8 pin CPU cables (top left corner). Make sure the rocker switch on the PSU is set to the ‘1’ or line side, not the ‘0’ or circle side. Check another outlet or surge protector if possible. An active adapter has an additional cable to receive power, usually from an outlet.Ĭheck to see the power cable is securely plugged into the power supply unit (PSU) in the back of the computer and into a powered outlet or surge protector. For VGA specifically, you will need an ACTIVE adapter to convert the digital HDMI, Display Port, or DVI-D signal to an analog VGA signal. If your monitor uses a port that is not on the graphics card such as VGA or DVI-D, you may need to use an adapter. Take the CMOS battery (silver coin) out, wait a minute for it to drain and then reinsert it into the motherboard. To make sure that it is plugged in correctly, there should be a clip on the slot and the plug itself. You can also re-seat a single RAM module in a different slot to see if the original slot is the culprit.Įnsure that the CPU power cable (black or black/yellow) on the top left of the motherboard is inserted securely by removing it and plugging it back in. If you have more than one RAM module, check each one at a time in order to isolate the defective component. Whether you have one or two locking tabs, you still should hear 2 clicks when inserting the module into the slot, one for each side. We find that it is easiest to slide the module in the bottom of the slot first, pressing against with your thumb it until you hear it snap into place, and then press against the top of the module. Then, insert the module back in the slot, one side at a time, making sure that the center notches align correctly and that the locking tabs on the top and bottom (if available) snap into place. Press down on the top and bottom slot (if applicable) to release the module. To remove them, check to see if there are locking tabs on the top or bottom of the slot that the RAM module is inserted in. To the right of the CPU cooler, there should be one or more vertical sticks. To re-seat the RAM module, first open the side panel (usually glass) that you can see all of the components. Reinsert the screws and close the bracket if necessary. You should hear or see the plastic tab lock back into place. Reinsert it, making sure it is firmly secured. Once the card is released, slowly rock the GPU back and forth horizontally towards yourself to remove the GPU. Press plastic tab on the right side of the motherboard slot that the GPU is inserted to in order to release the card, with your finger or carefully with the screwdriver tip. After you have moved the bracket, or if your case does not have a bracket on the back of the case, open the side panel (usually glass) and remove the screw(s) mounting the GPU onto the bracket on the left side with a Phillips-head screwdriver. If you see a bracket, you will need to loosen that screw and move the bracket in order to expose the GPU screws. To re-seat the GPU, first check the back of your case and see if there is either a sliding bracket with 2 screws, or a single hinged bracket with 1 screw. Re-seat the graphics processing unit (GPU), and RAM modules: Some monitors will be able to send a display to another device, but that same port will not be able to receive a display from the computer.įor any following steps, please make sure that the computer is off and unplugged. The exact layout of your PC may be different, but generally you will want to plug in the monitor cable to the graphics ports that are below the green, pink and blue audio ports.Ĭonfirm that the monitor cable is plugged into the monitor output port, not the input port if any.

The onboard ports on the motherboard (top left silver bracket) will only work with a CPU with integrated graphics chip. Check that the input source on your monitor is set to the same connection as the cable you’re using (HDMI, DVI-D, or Displayport) using the correct button on the monitor.Ĭonfirm the display cable is plugged into the DVI-D, HDMI or Displayport ports on the horizontal graphics card and not the vertical HDMI port. Most monitors have a button that lets you choose between the different monitor inputs. If it’s powered on, there should be a light on or near the power button and you should get an error message such as “No Signal”.

Make sure the monitor is plugged in and powered on.
