This gets a little complicated and while it is an internet problem, it seems to be a problem caused by Windows. I am running Windows 8.1 now, but the same thing happened in January while I was running Windows 8. Everything except the internet is working perfectly.
The system is running an i5-330 processor and has 16 gig of ram, I believe. Might be 8 gig of ram but I think it is 16, in any case, has plenty of it. Its main drive is an SSD that has about 65 gigs free space. It is a custom build from a local major computer store and it is just over 2 years old.
The computer is in the shop, so I cannot run any test but, the repair shop is totally out of ideas, other than to reformat and reinstall, AGAIN. They cannot figure out what is causing the problem so I don't want to that as I am afraid that since we do not know why the problem has happened, twice, it will just happen again, so I am really hoping that someone here will be able to offer some ideas as to what is happening to cause this problem and how to fix it without doing a reformat/reinstall.
I should have just come here before taking it in but I didn't have time to mess with it and since the place that built it offers free lifetime service, I took it in. They do charge an 80.00 expediting fee to put it in the front of the line but since it had been in for this same thing before and I was not happy about it happening again when we never found out why it happened in the first place, they were kind enough to waive that fee for me this time.
I want to make this very clear, there are no viruses on the system and there never has been. When this problem happened before, I ran many tests to be sure of that, and the repair shop did too. This time, I only ran a scan with my usual virus program but the shop ran their tests just to make sure too and it is clean. Btw, besides my ZoneAlarm always running, the full version of Malwarebytes is also always running on it.
Sorry for the long intro into it, but I feel all of that matters. The rest is rather lengthy too but I want to provide as much info as possible to try to get us on the right track.
So, on to the problem. A few days ago, after making no changes to my computer or doing anything out of the ordinary, many websites stopped loading and some would load but not work properly. Google will load but not do any searches, other sites load fine but many sites just never do load. I got strange messages trying to load mail on AOL.com, but when I reloaded the page it worked fine but AOL software program won't connect at all. Most sites that require a secure connection would not load although the AOL mail site is a secure connection and it did usually load.
I am using latest version of Firefox but I also tried IE11 and had less success with it. All Windows updates are up to date. Turning off virus protection makes no difference.
Before the problem happened, I had been of the puter most of the day just playing on my usual sites, the main one I was on was Publishers Clearing House games site just playing Solitaire but I was also on their main sweepstakes site and a medical forum. I had a few other sites loaded but I wasn't doing much with them. Everything was working just fine.
I made no changes to the system whatsoever and nobody but me is ever on that computer.
I left for the evening (nobody was here while I was gone) and when I came back I went back on the medical forum and then I tried to google something but Google would not google and that is when I discovered there was a problem. I tried to go to a few other sites, including the main one I was on all day and it wouldn't load either. At first I thought it was just the internet having problems as some sites were fine but others wouldn't load. Forums, including this one, worked fine, but most sites would not. Soon I realized it was the same thing that happened before so I tried the other computer here and the internet was working fine.
I used the network trouble shooter in Control Panel and it said that my system was configured correctly but the DNS was not responding. I ran SFC and while it found a few errors that it could not resolve, I do not believe that those were the issue. There were 6 of them all related to telemetry with Microsoft Apps (I rarely use the Apps, I run Classic Shell so boot to the desktop) and the computer techs also appear to feel they are not the issue.
The techs at the shop have ran tons of tests, tried a wireless card instead of the using the ethernet that I have been connecting with. This computers connection has been hard-wired. the other one in the house, which I am on now, is wireless, but that didn't work. They tried doing a non-destructive reinstall of Windows and that did not work. Did something with the Winsock and many other things they didn't go into with me, just said they tried everything that any of their techs could think of to try, but nothing is resolving the DNS problem within Windows.
Finally they tried using Linyx and everything worked just fine so obviously it is a Windows problem.
Again, sorry this is so long, I am just trying to answer all the questions I think anyone could have without making them ask them and wait for my reply, as I do need to give the shop an answer on Monday about doing the reformat/reinstall.
Does anyone have any ideas about what is going on here or how to fix it besides reformat/reinstall?
I would really appreciate any help anyone could give me with this.
