    Hi Lemmor and Johnyu_05, thanks for your help.

    I tried the monitor with another pc. The problem is not the monitor.

    Here are a few more details:

    The light on power button at front of tower does not light. Instead I have a solid yellow light underneath power button in front of tower. (harddrive?) The green cd rom and dvd rom lights flash momentarily at start up. Then only the yellow LED stays on.

    No other lights work.

    The cooling fans on the tower and the power supply box work when I power up. I have to hold down the power button until it shuts down.

    I don't know what the battery looks like nor where it is located. I do know that the only changes I made was replace the power supply and upgraded memory.

    I hope this info helps.

    Thanks so much for your help!

1. If you see your computer somewhat reading your files, "you should see the Harddrive LED flashing long or short for sometime", that tells you that the screen has a problem.

2. If no harddrive activity, then the problem will be on the motherboard, check the CMOS battery if it reads 3V or if it is more than a year old it needs to be changed.

3. Remove and clean the memory contacts and insert it back.

Now test the computer.

Post me back if it doesn't work.

Hi Lus;
What color do you have on the power button of your monitor? Check the VGA port at the back of your computer, how many VGA ports do you have? if you have 2, try the other port instead,

here is a VGA port:
hope you see the images,

ill wait for your feedback

    Hi Lus,
    have you check your VGA Port? do you have a video card? if yes, is it plug there?

    again, please check if you have 2 VGA ports or 1 at the back of your CPU. if you have 2, try the other look alike VGA port.

Intel D945GCNL has no display though ram, hard disk,power supply, processor is fine


Provided you have checked out the simple stuff; monitor, AND monitor cable, suggestion would be to install a graphics card, and connect the monitor to it.

You won't have THE drivers for the graphics card installed yet, as you have no display, but you should get a display you can see well enough, to install the drivers.

I do need to ask a few questions before this is done, however.

1) Do you know the Power Supply is good?
Your LED lights may light, fans may spin, and it may sound like the harddrive is spinning, but the Processor may not be on.


A) IF, all of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use 51 to 125 Watts of power. Just depends on what Processor it is.

{ The Intel D945GCNL mobo has an LGA 775 processor socket.
Front Side Bus support is 800MegaHertz.

The motherboard chipset is an Intel 945GC (Part number 82945GC)
Can use up to an Intel Core2 Duo processor, with a 800MHz FSB.
These processors can use up to 65 Watts.

I'll go with the chipset info, and not the stated 1066MHz support,

Stated facts from Intel, }

2) How do you know the;
A) Processor
B) Harddrive
C) Ram Memory
D) Power Supply
,is fine?

Connected them/it to another working motherboard? Won't work with the harddrive, unless Windows Activation screen comes up, and then the harddrive will be for THAT motherboard, and not the original one.

Post back in a Comment.

( Dell xps m1530 laptop ) Monitor blank, powers up but screen won't come on.

It ISN'T the LCD screen. Since you diagnosed with an external VGA monitor, you now know the problem is the laptop.

(When you connect an external VGA monitor to a laptop, you are bypassing the Video Cable, and LCD screen. You are connected directly to the laptop )

The basic Windows files aren't being found. The boot files. This may mean a bad Harddrive.

Do you have the Restoration CD Disk? Laptop on insert it into the optical drive tray, close the tray.
When asked choose - Repair. (Non-Destructive Installation)

If a checkdisk is done, you have bad sectors on the harddrive.
There IS a special procedure in replacing a harddrive.

The power is on but there's no display and the hard disk light is off

Is it absolutly nothing displaying on the screen when you are starting up your system, and just some lights coming from either the power/harddrive/battery status light? Can you hear the fan power on? If you do get something on your display, but then a blank screen after the post up screen, then your harddrive bad. If not... then, Alright let see, start out by connecting your power cord to the laptop while the battery is on to see if you get a battery chraging status indicator, if you do try to power the netbook and see if any thing works. If you still get a blank screen, then use the external vga port to a external monitor or something to see if you get any display, but I doubt it could be your screen, if you ain't hearing the windows welcome sound (if you are using windows) when it loads, unless you created a user password on your welcome screen prior to this incident. After that, if nothing works, take your battery out and power supply, press on the on button for about 30sec or so to see if it can clear the bios... sometime this will load the default value to the bios and it could work. If nothing happens, then it could be your rams. Take out the service port panel on the back, if you there are two sticks of rams in the ram bank, remove one and out and just try using one and power your laptop on to see if you get anything or do a vise versa to the other ram. If it works, you probraly have a bad ram. If not, then yeah we can say, it's your motherboard, either a currupt vga chipset, cpu, or simply the motherboard itself. If this is the case, I would reccommend you to sell for parts on ebay, craiglist and get a new one instead of trying to repair it. You can still take your hard drive and copy the files to another drive like your desktop computer.

My monitor goes blank after a while,power light still on,why is this & what can I do?

Check connection cable with videocard on your PC, unplug it and carefully plug it in again. (Turn off your monitor during this operation). If monitor goes black after loading OS (like Windows), then your screen resolution higher then monitor can support. Load computer in Safe Mode and lower screen resolution.

Tohiba l300 completely blank screen

If the screen is always blank, even on startup , before loading Windows, than this is probably an hardware fault.

Try unplugging the laptop and removing the battery at the same time, wait 5 minutes, then put the laptop together. This will drain power and reset the laptop.

If that does not work, and you get no pictuer under any circumstance , then there is a fault.

If the screen is black with no light , then it is either a faulty inverter or a problem on mainboard.

If the screen is all lit, but is blank with no signal, then it is often because of a bad LCD ribbon cable , but can be again the video chipset on the motherboard.

Try connecting to an external monitor, if it works then problem is restricted to LCD/inverter and ribbon cable, if it does not work on external monitor is usually a bad video chipset on motherboard.

Acer aspire 5100 blank screen

Try reseating the RAM modules. If that doesn't work test the RAM in another laptop. If nothing works chances are you have a faulty motherboard.

Compaq V5005us is weird. Powers on with black screen and freezes

It sounds like your Video card and/or motherboard are starting to give out or your LCD is giving way. Try plugging the laptop into an external screen and see if it still acts strangely or even displays on the external monitor.

Dell m992 screen problems

If you notice, when you see the windows start screen, its usually "big and dopey". Thats because the video drivers aren't being used yet. If it is blanking out right after you see that screen (with the scrolling bar), my guess is it's a corrupt / bad video driver.

Was any other hardware added recently?
