Windows 7: Certificate Issue

11 Jan 2014   #1

Windows 7 Pro, 32 bit
Certificate Issue

No doubt that this has been brought up before, but I cannot locate the thread.

I installed Win 7 on an XP PC. I purchased Win 7 on Ebay recently. Had all sorts of problems getting to just about every website. Certificate issues. I reformatted the computer three times and reinstalled Win 7 again and again. Still certificate issues. Even when I install a certificate for a particular site, browsers keep telling me the certificates are invalid, etc. This goes for both Internet Explorer and Google Chrome.

So I reformatted and reinstalled Win XP again. Same problems. I can't even get to Microsoft to revalidate my Win XP. Very strange that this would continue to occur even after I've reformatted and reinstalled the operating systems.

I even went to my router login to see if there were any issues, because this problem is constant, no matter what I try.

I also tried to install the MS root certificate, but my machine will not even open the program up.
I have two other Win 7 computers that do not have this issue.

After I installed Win 7 for the first time on this particular computer, I entered the key and got no errors. A couple of days later, a note popped up on the screen that this was not a valid Win 7 OS. The person I purchased it from says that it is. I've been getting some strange, perhaps virus traffic lately and I don't know if this is related. One message said that to verify the OS, I needed to install a certain certificate. The URL was from "Microsoft Com", so I installed the cert. That's when I began having all of the problems. But why even after numerous formats and reinstalls? Why on both Win XP and Win 7? Why on only this computer.

Very puzzling. Can anyone help?

After days of troubleshooting, I found the answer. The computer clock was showing the year 2005, probably because of a bad battery. I installed a new battery, reset CMOS and I'm good to go. The computer saw the certificates as invalid because it thought it was in the year 2005!
