Not sure if all the issues that have gone on are related or not, but I am going to provide the recent history of my computer.
SATA HDDs (qty 2)
Integrated video card
Pretty sure at 1 GB ram
Around 6 mos ago, I would occasionally get this screen lock up, kind of a pattern of small rectangles that appeared to to color-schemed based on what was on the display at the time it happened. I had tried seeing if it would revive itself, but never would, so when it happened, I would long-press power button to shut down and then restart; it would usually start up normally and off I would go. This would happen apparently randomly, in both duration of session as well as in terms of what was being done on computer, as far as I could tell. Read up, even came across a site that had an image posted that looked pretty like it. That site gave different possibilities, first one I tried was a 2nd HDD since I really needed anyway (had less than 7% free) AND I wanted to get files on a new drive in case it was the HDD and it was going. Anyway, did that, almost seemed to have a little positve effect, but not really sure. Then later, couple months later, power supply went. Replaced it, that was one of the possible suggestions I had come across too, so checked that off the list, but it would still have this lock up every once in a while. The suggestion I really liked was video card, but did not want to do that just yet with the cost, not too much, but could end up putting amount of a new computer in before I new it. The 2nd HDD could be transferred, so that was not a money issue.
After I had put the new 2nd HDD in and defragged orig HDD (now at about 50% free) and felt everything was in good order (no expert) I expected a decent performance boost as it had gotten pretty slow. But it really did not have one, maybe a little, but nothing like expected. So, I tested the HDD using the mfg utility, it said it was good. I also testing the ram using MEMTEST, said was good (I think 2 passes). Vid card still unverified.
Now, it will not even start at all in regular windows mode, but it will in Safe Mode. One thing I noticed while starting in Safe Mode with command was a hang up after, I think it was classpnp.sys. But eventually, within a minute or so, maybe less, would move on and start in Safe Mode.
So, not sure if there is a hardware issue, or possibly malware, so that is my question.
Thank you very much for reading and any input is greatly appreciated.
