You may have to reload the OS to see if there is a hardware issue. The details are so slim that I can't offer any advice other than reload.
My desktop computer (3 years old) takes roughly 6-7 minutes before I get internet connection. This just started out of the blue. Normally I would have internet before my desktop even finished loading. I changed out the wireless router and modem, all to no avail. Someone told me it could be a virus, although I've scanned with McAfee and Malwarebytes and it's found nothing. Someone else told me I may have a bad ethernet card. Can anyone tell me what I should try next. Much thanks in advance.
