My Site Not Opening from My Computer but Others Can See it

I am experiencing a hectic problem. I can not open my site, wordpress dashboard,ssh,ftp most of the times. Sometimes it automatically opens and stays just couple of minutes and goes away once again. I tried everything known to me. Formatted my computer with new operating system, changed different ISP but nothing working. I used OpenDNS but nothing actually taking effect. Please suggest me if you have experienced the problem earlier.
Thanks

 

I know this sounds silly but have you cleared your disk / browser cache? I had this problem with a popular website who changed DNS recently and Google Chrome actually was serving up the wrong page from cache.

 

I tried that trick. Additionally, I formatted my PC to remove everything stored cookies,temp files blah blah.. But not working..

 

Check the IP tables for your IP to verify that your location is not blacklisted. Also, perform a trace route to your domain.

 

+1 on this as you need to check if your IP is blocked.

 

IP is not in the list of blacklist. Tracer is not working after 10 nodes. Really frustrated.

 

this happened to me once
are u sure that this is only happening to you according me if you just changed hosts u should check if the dns settings like A records and all are good or not if they are then thats well and good if not u must fix them this usually happens when some records are missing

 

Can you post or PM the domain?

 

if you are using a wireless router to connect internet then , would suggest to reset it to default and setup again.

 

Have you try to access with proxy site?

 

have you done any tracerts?
