My computer:

HP Pavilion

Processor            AMD A8-5600K

Memory              8 GB

System Type      64 bit

Use both IE 10 and Firefox 24

My Problem:

My computer is blinking!  It blinks about every three minutes.  The whole monitor blinks.

Each time it blinks the cursor turn from a pointer to a busy for about one second.

If a pull down list is open, it will close on a blink

If I am filling in an answer  pull down the pull down will close and clear on a blink.

Certain games such as Peggle Delux miniaturize to the tool tray each time it blinks.

If I am writing in Word all letters typed during the blink disappear but not the ones  typed before and after the blink

Not every time but about every 10 blinks, Firefox errors out and closes


I have Norton Antivirus running.  Also use Speed Up My PC and CCleaner on a daily basis.

I have tried a different monitor and the blink still happens.

Hello and welcome to Bleeping Computer.

First, if you could do the following this would help us to better serve you.

Go to Piriform's website, and click the big download.png button.
  • Click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version.
  • You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.
After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.


Once inside Speccy, it will look similar to this (with your computer's specifications, of course):

  • Now, at the top, click File > Publish Snapshot
You will see the following prompt:
  • Click Yes > then Copy to Clipboard


Now, once you are back in the forum topic you are posting in, click the reply.png button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.

Congrats! You have just posted your specs! :)

Thank you and I'll be waiting for your next reply.

What happens if you boot into Safe mode with Windows, or use a Linux Live DVD.  Does it do the same behavior?  How old is this monitor?
