IT Queries: Computer problems answered

The computer just closed to a blank screen with the message no signal detected. We are running XP. I updated Norton Antivirus and then tried to scan in case of a virus and the computer just goes to the blank screen with no signal detected

The “No Signal Detected” message means exactly that; the computer monitor isn’t getting a signal from the computer. Basically it means the computer is off or the cable to the monitor is disconnected.

Sometimes it means the computer’s graphic card has failed.

In your case, it means the computer is shutting down when you run Norton. This is serious.

Either Windows is crashing due to a memory problem or, more likely, you have an extremely serious spyware infection.

We’d strongly suggest you call out a service technician to have a look at your system.
