Hi w2dsx,

8 Beeps issue is an LCD screen which is a hardware issue. You can update the BIOS on the system to check if it fixes the issue. Please enter your service tag # on the link below, select the OS, then download the BIOS from BIOS section onto the system and install it.

Hi Ravi, and thanks for getting back to me on this.  I did as instructed, and had the same problem after it flashed the BIOS.  Same as before - only works with a external monitor, speakers were muted (but was able to unmute).  When I had loaded the link that you provided, I tried using the Dell hardware assistant that is part of that webpage several times.  Each time it was halfway through the process but stopped and gave me a message saying the internet connection was interrupted despite having a clear signal and then using a network cable.

Some other things I have tried were using a Windows system restore point well earlier than my daughter said she had the virus (Minecraft update, it had bundled software that was loaded with malware, such as several toolbars and viruses such as Angry Birds and Winning) but still have the problem.

One thing I was considering was possibly rolling back the driver on the monitor to see if that worked, but I wanted to see what your opinion was first - thanks in advance!!

Best regards...

Hi w2dsx,

The LCD screen seems to be faulty you will need to replace it.

A virus can wreck an LCD screen? 

Hi w2dsx,

A virus attack will be an software issue. It will not make any hardware faulty on the system.

That's what I thought.  I'm sure the monitor is fine, I'm just trying to find how to correct the settings to make it work properly.  I found in the event logs that several settings were changed on the date of the infection, but I can not read xml.  If I were to post to post them here, could you possible direct me to the correct setting?

Hi w2dsx,

The System board gives out 8 Beeps from the system when the LCD screen is not detected or faulty by the system board.

Yes, thank you.  Since this coincided with a malware infection, I'm certain the monitor is fine.  I have been able to cleanse the computer of the malware infection with the help of folks at bleepingcomputer.com but all I need to do is to find the software setting to turn the monitor on, or disable whatever change the malware did.

I do have the event logs from the monitor driver window of the date of occurrence and can post them if you know how to do this.  I see several entries where the monitor is set to 0x0, but I don't know xml enough to change it back.  Are you able to assist?

Thanks in advance!

If you get no BIOS screen its 99.9% hardware related as you haven't even got to the OS at this point, if you can get to the BIOS creen but it then lose it on the way to the OS loading its software, simple fault finding.

Hi w2dsx,

It should be mere coincidence that there was virus infection and also hardware issue. As informed earlier System board gives out 8 Beeps from the system when the LCD screen is not detected or faulty by the system board.

I agree!  The only problem is I'm unfamiliar with the proper fault finding process, being a man with a little knowledge.  I"m looking at the event logs on the date of occurrence and I know it's staring me in the face, I just don't know xml langauge...  yet!

Hi w2dsx,

As informed earlier the 8 beeps indicate LCD screen failure as the system board is not able to detect the LCD screen. I would suggest you to remove and reseat the LCD screen on the system with a help of technician using the manual. In the link below punch in the system service tag or express service code and you can access the user manual for removing and reseating of LCD screen.
