Tip & How-To about Computers & Internet

No Display

If a computer or laptop has no display, check the ff:

1. memory module = isolate by using other memory module with the same specs.
2. video card (for the desktop) = isolate by using other video card with the same specs.
3. video card (for the laptop) = use monitor or lcd to test if video card is defective.
4. monitor or lcd = use other monitor or lcd to distinguish the problem
5. video cable (for desktop) = use other video cable.

hope this might help everyone.

I have a Gateway MX8734 laptop - it's about 4 years old or so. Almost every time it's moved while on, it shuts down instantly. Other times, we get a BSOD error indicating that something's up with the video card/driver. I've read other's reviews about frequent hardware problems. We've had no problems whatsoever up until a few months ago. Any help would be appreciated.


Hi,

I see how frustrating it can be to have a computer that is as unreliable. In this issue, as you described, I see that there are a couple of things that might be causing the failure in your portable system. One is the video card driver, another is the memory module. The reason for the failure on the memory module is that once an operating system is loaded into a computer, it gets loaded in the memory module, and failure of the device will usually result to BSOD.

Here is what you can try to do to further isolate the issue.

1. uninstall the video driver of your computer
a. press the windows key + R
b. type devmgmt.msc then click on ok
c. click on the plus sign beside the display adapter and you should see there something that says Intel GMA 950 Dynamic Video.
d. right click on that item and then choose uninstall.
e. download this file into your computer desktop: video driver
f. restart your computer. when it asks for a video driver for your computer, cancel it then double click on the driver that you downloaded into your desktop.

if this does not resolve the issue, you will need to do trial and error on the memory module on your computer.

2. Reseat the memory module on your computer. Download this user manual so that you will be guided in getting access to the memory module of your computer.

3. if step 2 does not work try to work your computer with one memory module at a time (assuming that you have two memory module installed in your computer. This is to find out if there are any defective memory module installed in your computer.

I do hope this information is enough to fix your computer. Do give me an update on what happens so that we will be able to further diagnose your concern.

Note: it would help much if you take a note on the BSOD error that you encounter.

Hi

THe most common beeps that you will encounter 95% of the time in repairing PC's are:

1 beep - computer ok
continous beeps / long beeps - memory error
continous short beeps - bios boot block/corrupted bios
1 long beep followed by 3 short beeps - video card error


or this might help

you can check out this list

2 short - RAM failure
3 short - Parity RAM failure
4 short - System timer failure
5 short - Motherboard failure
6 short - Keyboard controller error
7 short - CPU failure
8 short - Video RAM failure
9 short - ROM BIOS error
10 short - CMOS read/write error
11 short - Cache RAM error
1 short, 3 long - Memory failure
1 short, 8 long - Video adapter failure

Check board/chipset makers website for more infomation.

AWARD BIOS

1 long - Memory error
1 long, 2 short - Video error
1 long, 3 short - Video failure
Continuous beeps - Memory or video failure

note that AWARD relies on motherboard manufacturers to develop their own beep codes - the above are only their own internal codes. You will need to refer to your own manual for an explanation of precise codes.


Standard IBM beep codes.

No beep - Power supply or motherboard failure

no display


This issue could be with the video card that is integrated on the motherboard.
However, to isolate the issue with software or hardware please follow the steps below :

1. Disconnect the ac adapter and remove the battery from the laptop
2. press and hold the power button for 30 seconds
3. replace the battery and connect the ac adapter
4, turn on the laptop and check

if the issue persists then remove and replace the memory modules and check for the issue.


If the issue still persists then it could be a hardware issue and your laptop needs to be serviced.

no image in monitor


isolate it first. there are 3 steps: step 1: isolate the monitor. use other monitor. if still no display, step 2: replace video card. if still no display, step 3: replace memory module.

How much ram?


Hi griff22_petm,

It is not you. The Biostar uses an intergrated graphic card. In your manual on page 2-13 & 2-14. Advanced Chipset Features.
You can set the total amount of system memory for the graphics card to use. Currently you have the bios set to use 8Mb of system memory to run your graphics card. (A wee bit low). If you need the manual you can download it from Biostar at this link:
http://www.biostar.com.tw/app/en-us/mb/content.php?S_ID=154

There is one other way to use all your system memory & that would be to buy a PCI video card, this would free up all your memory. Suggested PCI graphics card:

Good luck griff22_petm!
