I have a number of issues with my computer (fairly new Acer desktop machine) with Windows 7.
The latest issue, which has basically caused me to be at my wits end is, while working normally, the monitor screen suddenly goes blank (it says 'no signal') and then nothing can bring back my screen. I press Ctrl Alt Del once and then a few tones sound, and then basically the computer fans just die down. I press Ctr Alt Del again, and then it restarts. After restarting, Windows gives me a message (attached image) which basically says that I have recovered from a Blue Screen error (however I never really see the blue screen). I dont know why this has been happening and what is causing this? It happens now and then few times a day.
Previously (and still is), I get random pop up messages in windows saying that 'you are not running genuine windows' and I need to go online to register or something. I have not clicked through the link to Microsoft as I have purchased a genuine copy of Windows (pre-built in Acer) with a proper serial number. That indicates there is some problem somewhere so if anyone knows how I can fix it, it would be great.
Can you kindly help me with all this? It is extremely frustrating.
Thanks for your help.
