Reflow Desktop’s Motherboard – Explained

Symptoms: Lines on the screen, No display and overheating of GPU chip.

If you having a desktop computer with a graphic card attached to it and it also shows you some vertical or maybe some colorful lines on the screen and it’s also possible it was given you a blank black display or I say no display screen on your Computer’s monitor.

If that’s the case with you then it means you do having a problem in your GPU chip of your computer’s motherboard and in this tutorial I’m gonna show you how you can easily reflow a desktop motherboard’s GPU (graphic) chip at home with common household kinds of stuff.

But first thing first if you just having a no display problem with your computer then I’ll highly  suggest you to check our given tutorial below this paragraph before you’re trying to do anything with your motherboard because sometimes it can be possible this no display problem can be generating just because of some minor hardware failure and its best to troubleshoot it before trying this reflowing thing.

I know you are thinking about “What Is Reflow And Why We’re Doing This?” So, the reflow word describes the process of melting the solder on the electrical circuit board. We do this reflow stuff because a bad solder joint in the GPU can cause a fault of no display or maybe showing some ugly lines on the display, that’s why we need to provide the high heat to the GPU’s chip for rejoining the solder by melting.

If you having a graphic card installed in your computer then remove your graphic card and try to turn on your computer normally. If you find problem with your graphic card then here’s we have another tutorial to show you:

So Let’s See

STEP 1 – Disassemble Motherboard

The first step is to do is, take off your computer’s motherboard from the cabinet. Please make sure your motherboard isn’t in under warranty because doing reflow can void your motherboard’s warranty.

If the warranty remains, then get it repair by the manufacturer’s service center or otherwise continue with our tutorial.

STEP 2 – Find The GPU Chip

The easiest way to find the GPU’s chip on your motherboard, you’ll need to look for the biggest chip nearest to CPU Socket.

STEP 3 – Cover the Motherboard

In this step, you’ll have to cover the motherboard by a metal sheet or a foil paper and expose the GPU chip only because we don’t want to damage the others components on the motherboard.

STEP 4 – Maintain The Heat

Let’s Preheat the Heat Gun to 385F (195C) with a normal air pressure.

Note – High hot air pressure can blow away the components on the GPU’s chip so be careful and maintain the low air pressure with high heat

STEP 5 – Blow Heat To The GPU

Heat the GPU chip very slowly just only for 5 – 8 min at 190-200 degree Celsius max and let the heat gun in motion. I means don’t hold the heat gun still on the top at the same place for even a single minute.

STEP 6 – Let It Cool.

Now Leave the motherboard for a while and let it cool down for a little bit, even how much time it takes.

STEP 7 – Testing

Now assemble back your computer and test the motherboard by attaching all the hardware components. If the motherboard still doesn’t work after heating then you should repeat this process and this time, you’ll need to try it again by increase the heating time (not the air pressure).
