I've run into this once..

check your windows date.

if you are in the wrong month or year, this caused the issue for me.

One of the first suggestions i got was the date/time. It seems correct, but if i try to re-sync it, i get an error. Googling it suggests re-registering the windows time service. Re-registering leads to another error. You see that everything's going wrong redface.gif .
Yesterday, though, i noticed something new. Checking windows event viewer showed me that 3 types of error occured every time i got an SSL error in any of my browsers.




After searching about those, google gave me some threads, but those guys were having these errors when trying to use SSL for their own servers using Windows server versions. Some solutions included changing the permissions of the certificates on C:/ProgramData/microsoft/Crypto/RSA/Certificates. I failed to change the permissions because it said i didn't have enough priviledges. Using and elevated commandline failed because, as it said, the command lacked parameters, although i entered them exactly as the solution suggested. The problem is there, but i can't fix it.

Your system has no reason to access another system's private key (unless you're attempting some sort of an attack).

Given that you're getting a bad MAC, it's either a hardware issue, or some library that's supposed to take care of that checksumming is doing something wrong. If you want to fix a low-level problem, you're going to have to use low-level tools. Get Wireshark and see if you can find anything related to this issue, or perhaps a proxy like Burp or ZAP as I suggested previously (more likely to help since it sounds like it may be in the application layer).

PS: if you want to try another high-level test, fire up a live Linux disk and see if you still have these issues.

No, no attacks. These errors are logged the moment I'm accessing the Internet and get the ssl error that prevents me to enter any site. What about the error though? I probably didn't quite understand what solutions I found because they were for Windows server users, but one I understood was that that folder wasn't accessible by anyone, so the certificates were unusable. A probable solution suggested that changing the privileges of the administrators on that folder solved the exact same problem on his computer. Problem is mine throws another error why trying to fix this one.

I've got to the bottom of this guys. Turns out it was the CPU. My guess is that being faulty there were constant problems with windows time and as a result SSL protocols.

Yes. It was the CPU.
I installed the Celeron. No SSL errors, no wrong time, no Windows errors. Everything's perfect.

That's really weird. Usually if the CPU is bad, then you'll see a lot more going wrong rather than strictly one application-layer thing.

I thought you said that time was fine?

Time seemed fine. I stated in another thread that the time displayed in windows, was different from the time displayed inside some programs. For example, MSI Afterburner OSD was two hours ahead. This was random. BIOS, windows and application time and date were different.
