Hello, My name is Tim and I will assist you in finding an answer to your question.

tbwhite2040 :

Restart the computer and start tapping the F8 key repeatedly. This should bring up the Advanced Boot Menu. Choose the Last Known Good Configuration and press Enter.

trying now

JACUSTOMER-4q6nsu1r- :

Nothing happening on the screen, but I know it's on.

JACUSTOMER-4q6nsu1r- :

s

JACUSTOMER-4q6nsu1r- :

Still have a blank screen after pressing F8 repeatedly, so can't see an Advanced Boot menu.

tbwhite2040 :

Do you see anything while the computer first comes on?

JACUSTOMER-4q6nsu1r- :

Not this time - it was black the whole time.

tbwhite2040 :

Does the monitor Power LED come on and dim back as though the monitor is off?

JACUSTOMER-4q6nsu1r- :

It did earlier

tbwhite2040 :

Then you need to check your memory to make sure it is not bad. I would remove all but one stick of RAM and run a diagnostics on the RAM to see if it is bad

JACUSTOMER-4q6nsu1r- :

I guess this is the part where I take it to someone then.

tbwhite2040 :

It is easy to do
