I posted my issue a few days ago. Uncharacteristically I received no help.
Have I done something wrong ? I wonder Why ?
My windows 10 ,16gb memory, terabyte hard drive with ssd 64 gb to help quick start. On a Gigabyte H61 board. It has been working fine since the window10 start. I have Malwarebytes full protection and depend on Defender for other protection. I use a long Ethernet cable for my Internet, although I have other computers using the same router wirelessly.
One day the internet did not work and trouble-shooters indicated that the Ethernet is defective. I left the pc switched off from the mains for a day as it was not important. Next day it worked fine without any effort on my part. It happened again I checked the Ethernet cable and found nothing wrong. During the investigation I found a message that the drive needs repair. I knew my drive was sound, but gullibility prevailed and I clicked, it informed me that it will take an hour or so. I got busy doing other things on my other computer and came back to it. It was turned off. I booted it and as normal the password page opened I put my password in and clicked expecting it to start. No it did not start it presented with the password page again I complied and put the password again. same result. every time I put the password in I could see my internet light was on.
Is it malware, virus or just another glitch !
I have my memory stick with Windows 10 but have forgotten how to use it, I am 81 and often forget procedures I have performed previously without hesitation and succeeded.
Please help.
