I have a Dell laptop with Windows 7 and right now all I can tell you is it's an i5 PROCESSOR, 8gb something, 1TB something - I can't look right now because that is the problem. My husband uses this and said, hey I don't get a little arrow on my desktop to click on anything, the little circle just keeps GOING around. So I started looking at it and it is more screwed up than he thinks. I cannot access anything on the desktop, nor can I access anything from the start page. It tells me "System call failed." I can click on Start and it will show me everything, but it ALWAYS says System call failed when I click on it. If you go to the taskbar at the bottom, you can get on IE. I tried to update Microsoft Essentials to start running a virus scan, same message. I am running a virus scan on it now, SEEMS to be working, and I'll see what it says when it finishes. If there is a virus, I know what to do, how to send all the info to you guys using CCleaner and Malwarebytes, etc. If there is no virus, I haven't a clue as what to do next. This computer is seldom used, maybe three times a week for an hour or two, so I'm not really all that FAMILIAR with it as he's the biggest user of it. I have my own computer which is what I'm typing to you on. Any suggestions if the virus scan shows nothing - what do I do next? Thanks!
You could try a System Restore to a date before this problem started.
