    It is not actually built into the board, the problem seems to be in supplying a replacement card that will work otherwise I will have to buy a new PC.

It appears to be a faulty video adapter, which would need to be replaced or if the adapter is build into the motherboard the motherboard would need to be replaced or in rare cases repaired..

    Dell machine? You have to contact dell directly for replacement parts. or look at pchub.com or ebay.com

    You will have to get in touch with a service center locally if you cant purchase one, a service center will be able to replace the part.

Laptop has jumbled horizontal muli-colored lines flickering and rolling, can't see screen


You should try to connect a VGA monitor to your laptop and see what happens. It sounds like a video card failure, and often the hdmi and the VGA are powered by different graphics chips.
If it works with a VGA monitor, try to install a new driver for your graphics card. Otherwise, try a system restore. That often solves your problem.
If a restoration doesn't help, your graphics card is probably broken. Get a new laptop. Avoid Acer :)

1) Laptop OFF, monitor OFF.

2) Connect the VGA cable of the VGA monitor, to the VGA port on the Left side/Rear of the laptop.

You can use a CRT monitor (Looks like a small TV), or a flat LCD screen monitor with a VGA cable. (Or DVI to VGA adapter on the cable)

3) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the display should show up on the external VGA monitor.
If not,

Press the Fn key down, and hold it down. At the same time tap once on the F5 key.

No display? Hold the Fn key down again, and tap once more on the F5 key.
There are at least 3 options available;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Intel GMA 4500M graphics chipset. It is Integrated Graphics, and NOT a graphics card.

The GPU is soldered directly to the motherboard,

Monitor not showing picture, but has power


Could be the Graphics card is out, or the VGA cord is damaged and isnt giving video but is giving some sort of signal to engage the monitor.

Powers on but no screen


There may be problem with your Monitor or VGA Card.
When you turn on computer after sometime the monitor light will be orange colour it mean there is no fault in monitor. VGA Card is not sending signal on the monitor. you should change your VGA Card slot if the problem is still exist. Replace the VGA card or have a local tech take a look at the VGA card.

That red line


give more details please.
- case 1 : does it not turn on at all ?
- case 2: or does the screen stay blank with that red line, but laptop still makes noises (a sign for hardware activity and a proper boot up..!, but the lcd monitor is broke then)
- case 3: or do have a steady red line on the display all the time whatever you do in windows?
(your lcd monitor maybe damaged in that area,) you will have to use it that way..then.

you may try to connect any other vga monitor to the laptop's graphic card (the 3 -row pin input in the back of the laptop) to double-check.
In both last error cases, just to see if error is still there (if not, you're lucky, work with the external monitor then.., if yes, it's the laptops' graphics card then, bad luck as in case 1).

check this out, if still problems, please give more prob details - you know where to find us, don't you? :-)

Power light flashes with no display


That usually means that the connection between the PC and the monitor has been interupted- check that the cable (probably has blue ends) between the two is firmly connected, and power it back up. If that doesn't work, you have one of three problems; a broken VGA cable, a broken monitor, or a broken video card. Finding out which- you'll actually need someone tech-savvy there to help you figure that out. Try plugging the monitor into a different computer. If that fails, use a different VGA cable (cables are pretty cheap at monoprice.com), and if that fails, it's your video card.
