High ping issues.

Hello All. I have a very difficult problem and I'm on the verge of changing my motherboard to fix it, although I'm not even 100% sure that will do the job. Let me explain.

This problem has had me perplexed for quite some time. I have tried NUMEROUS fixes and NONE of them has helped at all. The problem is I will get high ping that I can only seem to fix by unplugging and replugging the ethernet cable into my computer. I will go through what I know in dot point format:

- I know it isn't the router, as I've been through 4 different routers and the problem has persisted.
- I know it isn't the internet service provider as as I've been through numerous ones of thise
- I know it's not the physical connection to my house as it's been happening on both ASDL copper lines and a newly installed Fibre Optical cable this year.
- I know it isn't software as I've completely formatted my drive to remove the problem, to no avail.
- I have bypassed the ethernet plug in into my computer by plugging an external ethernet card into the motherboard and using that, so it's not the ethernet port.
- I have changed the ethernet cables, no fix.
- I have a second computer on the network what doesn't get the same problem at all.
- I have removed all dust from the electronics
- in CMD i ping the router (192.168.1.1) and the request times out often, localising the problem to be between the router and the pc.
- It happens over wifi and direct connection.

the computer didn't have this problem for the first 1.5 years of it's life with me, then one night halfway through playing a game, it begun. Like I said, unplugging and re plugging the ethernet cable into the PC CAN fix it, but some days I'm there for 40 minutes doing that to get results.

I have posted this on a few other forums but didn't get much help and I have had to give solving it a break cause I've spent hours on it and it just became overwhelming. But I would lke to finally sort it out.

Andway hopefully this is enough information. Maybe there's someone on this forum more knowledgeable than the previous forums I've been on.

Thanks in advance
