It does not do to ignore warning signs. Some months ago, my computer would not undertake a full malware scan with one of the programmes I have installed. It was happy with the quick scan. My other malware programme, which takes a long time to perform a full scan was okay. I had one that did and one that didn't do the whole job, I was comfortable with that.
Next, after leaving my computer for, say half an hour, I would return to find it had closed down and re-booted. Very odd, I thought. If I set it to sleep mode (standby) I could return to my earlier work. Answer...use sleep mode. However, irritating things happened, like freezing of programmes just a little too frequently.
The last straw was my newly updated and paid for anti-virus programme could not complete a full scan,. though it was able to trot through a foreshortened scan. It was definitely time to speak to an expert.
The diagnosis is a corrupted hard disk, the damage appears intractable. I can't complain though, it is the original drive and my computer in I.T. terms should be on life support. Fortunately, all my data is on another disk drive. The fix is to get a new hard disk and move my programmes onto the new one. It has been explained to me how it will be done.
The silver lining in all this is, I shall obtain a much larger capacity drive, I won't need to ration my programme updates and downloads and my computer won't need resuscitating again for a good long while.
It was fortuitous that a long time ago, I had installed a second disk drive, separating off my data from the main disk drive to avoid the problem of corrupted data. But.......and it is a big 'but', I should not have ignored the warning signs.
I'm off now, to do a back up of all my data on my external drive.
