Hello, last week I bought a new graphics card and before plugging the GPU I first plugged the fans in the 4-pin molex.I then accidentally touch the motherboard and felt a ground of electricty in my fingers, I know its the static electricity. Can my motherboard still be fixed? My PC is not turning at all not even a light although the PSU works fine.

I think that's an Andyson made unit. They're not great, but if it is the unit I *think* it is, they're not complete junk and should handle an i3 and 1060.

That PSU has a 6+2 pin PCIe power connector which should go straight into your GPU. You should be able to separate the +2 pin bit (it ends up just hanging around in mid-air, but that's fine), and use the remaining 6 Pin connector for the card.
Does it boot if you use that?

If not: does it boot if you take the graphics card out again?
If not: you need to clear the CMOS and pair it back to...

There's two things concerning about your request. The static, but also the GPU into a 4 pin Molex. Can you list your full PC specs (CPU + Motherboard, GPU and PSU make/model)? Also, what was your old graphics card and do you still have it?

While technically it *can* be fine to power a GPU off a molex adapter, the worrying thing is that any even half decent PSU should come with PCIe cables for your GPU. The fact that it doesn't makes me concerned that it's a very low quality PSU, which potentially shouldn't be anywhere near expensive PC components.

So step 1: Let's find out what your PC components are so we can make sure everything is safe to run
Step 2: (if it's safe to run), we'll try to pair back everything to bare-essentials to try and isolate the issue.
If you did accidentally discharge static through your motherboard, then it's totally luck of the draw. If you happened to tough a ground line then you should be absolutely fine. But there are plenty of critical circuits which a decent static zap can destroy. If that's what's happened, then I'm afraid you're looking at a replacement motherboard. Let's do the proper diagnostics first though.

My cpu: i3-6100
Motherboard: MSI H110 PRO-VD
Gpu: i have no GPU when the accident happened. I just bought a new one its Palit GTX 1060
PSU: Rave 500watts 80plus

Sorry i forgot to mention earlier, when I checked the outlet it turns out that I forgot to unplug the PC after shutting it down. Shame this is all because of my carelesness

I need the specific make/model of the PSU.

Ideally when working on a PC you actually leave the PSU connected to the wall, but you switch off the physical switch on the PSU (if it has one) and switch off the power at the wall socket. Even with the wall socket off, the ground (or "earth") wire remains connected, so the PSU, case and motherboard all remain "grounded". That way, touching the metal case or PSU cover will safely discharge any static electricity you may have accidentally built up.

I'm still very suspicious of your PSU. It's possible everything else is okay. Don't panic yet. But unfortunately it's not looking great.

PSU make/model please.

The PSU is Aerocool RAVE 500w 80+

If not: does it boot if you take the graphics card out again?
If not: you need to clear the CMOS and pair it back to absolute basics
- Physically disconnect your PSU from the wall (just in case some protection circuitry has been tripped - sometimes they need to be left for a while before coming back to life)
- Reset CMOS (look at your mobo manual - should have instructions)
- remove GPU
- disconnect all HDDs/SSDs (power + SATA connectors)
- remove any other expansion cards you have in (sound cards, network cards, etc)
- remove all but one memory slot
- reconnect the PSU, but don't turn it on until the PSU has been off for ~10 minutes or so

See if it boots.
If not - try a different stick of RAM in a different RAM slot.
If still no boot... it's not looking good.
