won’t turn on after installing a new GPU
Like we did with the previous problem, some people may encounter a problem where they install a new GPU and end up with a computer that won’t turn on, you’re not going to apply the same tips mentioned above except for a few ones, let’s see how we’re going to fix this one.
Warning: Never install a new GPU while your PC is running.
A PSU Problem
A new GPU may require more power, and who is responsible for providing your computer with power? Yep, the PSU (power supply unit), if the PSU can’t provide the new GPU with enough power it may not work.
Install it on another computer
To make sure the GPU you just bought is working fine and not defective install it on a different computer, if it turns on then it’s a sign that the problem is in your computer, if it doesn’t turn on then you got a defective GPU, my friend.
If it’s still under warranty go ahead and replace it with another one.
Extra Tips
- Reseat the RAM: don’t underestimate this quick tip, reseating the RAM may fix some problems.
- Reset the CMOS Battery: resetting the CMOS will reset the BIOS to the default settings.
- Make sure that the graphics card is well seated into the PCI slot.
- If the graphics card needs additional power through a power cable then make sure it’s connected to it.
- Before you install the new GPU: some computers will require you to switch manually to the PCI slot instead of the onboard graphics, disable the onboard graphics from the BIOS settings so your system can identify the new GPU, if you were able to log into your computer through the safe mode and disable the integrated graphics driver that’d be great.
I don't have your board but most of the time code 00 is caused by three things, a faulty psu, motherboard or cpu. Testing with three psu's I think we can rule out the psu. There are other things that can cause code 00 like bent cpu socket pins, corrupt bios, failed memory training. Try updating/reflashing the bios via the bios flashback method.
