Re: Blank Screen

Id say its hardware. try pulling the hard drive out and checking to see if posting gets any further.. it also could be the cd drive causing the post hang.

Turn computer on, the acer logo comes on screen then goes blank, nothing happens

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

Compaq CQ50 wont load

YOU are to be COMMENDED!

Do you know how many do not even post the manufacturer name of the computer, much less the model number?

Plus adding the diagnostic measures you have posted?

Wish more people would use the problem area you have used, and wrote a PAGE! lol!

Do need the model number though, along with the model series number you posted. This way I can look at the BIOS versions.
(Example - CQ50-100CA)

Need to CDROM the first boot device in Boot Options?
(BIOS Setup)

Could be of course, but you didn't post it. Makes a BIG difference.
The computer HAS to boot from the CDROM, then.

Post back in a Comment.

Starts up goes to start windows then goes off and comes back to start again

It is more than likely the hard drive, or the window files are corrupted, if you have a backup recovery disc try it now, no change! have the hardware tested.

Hi i have a compaq presario laptop and after it stars up the screen just goes blank

Hi there,
do you still see the compaq logo and does it show you the windows boot up screen before it goes blank?
do you see anything on the screen at all after pressing the power button?
Check if the laptop is receiving power. If it has power and you can't see anything on the screen it could mean that the LCD assembly or the Video card of your laptop is bad.
If it goes to the compaq screen and then to windows logo before going out, try booting into safe mode and once there uninstall the video driver from the device manager because that means the resolution was set to something higher than the display could handle.
If it restarts after showing the compaq screen try reseating the memory, hard drive and wireless card of your computer put them one by one and try turning the compter on after each part you put back to check which component is point of failure.
Otherwise you have a bad motherboard and it may have to be replaced.
Hope this helps!

Just got cq56-115dx laptop this morning. turned it off after setting it up. Turned it back on and only have blank screen. Power shows lit up.


Remove the AC power (charger) and then take the battery out. Plug in just the AC power supply and turn the laptop on, see if it boots up and shows a display on-screen. If it boots let it boot up and then shut it down as normal. Reinsert the battery and try as normal.
If you still get a blank screen can you then tell me if you get any post (splash) information like the Compaq Presario logo before it goes blank.

Good luck.

Laptop powers up but a blank screen shows with two green lights showing up top whats the problem

PLug the laptop into an external monitor to see if you get video to the external screen.  You should have a vga port on your laptop, connect it to the laptop and then turn it on.  If you see video the onboard video card on the laptop is fine and most likely you have a bad lcd.  On the other hand if by "powers up and then goes to a blank screen" you mean its posting you see the asus splash screen and instaed of going into windows you see a blank screen.  in that case you mos likely have a bad hard drive or corrupt operating system.  You can test the hard drive by downloading dft and booting from that cd.  here is a link to dft

My computer turns on sometimes the quickly goes blank. Other times, the On light comes on but the screen stays black and nothing seems to be moving inside.

try to desconnect or unplug your hard drive, if you see a black screen with a bunch of white letters, you hard drive is crashed, if not try to conect a second monitor (external) tru you vga connector, if work fine you have a lcd problem===>>>reemplace asap.
