Computer shows black screen after safemode start up

  SeanDabbs 13:53 01 May 2015

please help!

My computer was running fine, I wanted to run in safe mode - after unsuccessfully restarting in safe mode via the restart option, I went into the boot tab and did it that way (as shown here - 5 Ways to Boot into Safe Mode in Windows 8 & Windows 8.1)

After restarting, the computer turns on lights are working but monitor shows NO signs of life at all, no cursor, no flickering of anything.

I changed monitors and restarted, checked wires, turned off and on several times. Tried pressing f8 on start up, tried pressing f8 and shift on start up - but NOTHING

I also spent the last few hours combing through similar threads, most of which mention a windows 8 update and incompatibility with the graphics card. I purchased my computer only a few months ago, it came with windows 8.1 pre-installed. I use the computer for 3d sculpting so it is pretty powerful for that reason

PLEASE help!!

What video ports does it have? Possibly it reverts to on-board graphics in safe mode.

a VGA port and HDMI (tried using both) . How would on-board graphics make a difference? thanks!

If you've tried both ports in safe mode then no difference. Depends if you have a dedicated, as well as, onboard graphics. Google shows this about your machine but its all Spanish to me.

Hi seanDabbs,

May be RAM issue cause the monitor with no signal.. swap out the RAM hear beeps...and then clean the slots.. Replace it... Hope it helps.

many thanks for the advice dashing_star , how do 'swap out the ram?' just take it out and put it in again?

just to be clear - I tried starting in safemode a couple of times before, but the computer did not 'seem' to boot up, so I just reset it, and it ran normally (no safe mode). Then I selected 'start up safe mode' as a boot option (from MSCONFIG), that is why I have this issue now. It seems when I tried to start up in safe mode before the computer WAS booting up, it just wasn't showing anything on the monitors like it is now

rdave13 - how do I determine if I have a 'dedicated, as well as, onboard graphics'?
