Remove all RAM modules - system should beep when you switch it on. If not then your CPU is not working.
Can you see anything on the monitor?
Does the keyboard lights flash when you switch on after several seconds (caps lock, num lock, scroll lock lights flash)

Mather board Gigabyte Ga-G41M CMOS checksum error -Defaults loaded and keyboard and Mouse are not working


Replace the battery and make sure it has a good connection in it's seat. Download and reflash the BIOS again. The original download file may have been corrpted. If those steps don't fix it then there are only a couple remaining things that could be happening:

1) Bad CMOS memory chip. This does happen. It's a small, couple K battery backed chip. The chip itself, mainboard tracings or circuitry leading to it could go bad or be defective.

2) Mainboard is shorting on the case somewhere. The tracings on the mainboard can definately short/ground or have periodic shorts causing the cmos memory to become corrupt.

3) Something electromagnetic is effecting the CMOS memory. A poorly shielded fan or other magnetic source is wiping out the CMOS memory periodically. You don't have like a refridgerator magnet on the side of the case do you? :D

4) Temperature. If for some reason your mainboard has a hot-spot, excessive temperatures for the CMOS chip can cause it's contents to scramble.

5) Unstable power. If one of your voltage rails from the PSU is bad, it can wipe CMOS memory contents. Get a hardware monitor and let it run to watch voltage ranges.

6) BIOS virus. Some virus attack the BIOS/CMOS memory space. Run a full scan and if you cannot afford a good virus program, try AVIRA. Even if your system comes up clean, look for patterns in usage (like a particular CD you use when it happens, etc.etc.)

I'd say it's most likely just a bad chip/mainboard. I've seen this before.

Hi, I have a Dell A960 that prints blank pages. I have tried removing the cartridges and cleaning them with vinegar on a paper towel until ink stains the paper towel, I have tried cleaning caked ink off of...


If not even the test page works then it's a hardware problem with the printing heads. In that case the there is only one thing left to try: put some new cartridges in and see if they work: if they don't then the fault is either in the connection between the cartridge carrier and the mainboard (with the thin flat cable on the side) or with the processor on the mainboard.
You will have to dismantle the printer completely and check the cable for damage and reseat it; then look at the mainboard for signs of damage - use this opportunity to do a full cleanup. If even after this the printer is still not working then the processor on the mainboard is defective - the printer is dead, time for a new one.

I have got a system with an Aopen motherboard which having only a 20 pin connector for smps connectivity. the Atx smps i have is is 24 pinned. i can connect the main line by splitting up the 24pin...


The actual Processor fan connects to the CPU Fan header on the mainboard. It's 4 small pins. It plugs in right near the CPU socket on the mainboard. Check the user manual for exact placement, you may download it from the AOpen website if you don't have one already.

Plug in the 20Pin connector if that is the most Pins that the mainboard will allow. Cable tie the other 4Pins back onto the 20Pin connector.

Then if there is additional 4Pin connector required by the mainboard for CPU power and you don't have that connector on you power supply, you will need to purchase a Molex to 4Pin CPU power connector. When you go to the computer store check with them that all is correctly connected.

Take care!

Hi , my dell inspiron 6400 vista has no disply but external monitor it shows fine ?


Hello,

If the external monitor is fine then there might be the issue with the display panel cable ( cable which connects mainboard with display) or the display itself. Ypou will have to replace.

Thanks

The monitor led is green but it gives white flash and still blank


Check the volatage regulator in the mainboard resolder all you found dried unsolder parts inside mainboard. Voltage test the regulator IC if have a voltage flow 2.5 to 5v DC. check ribbon cable connector from mainboard to controller board if properly connected. In the controller board find the small fuse test it for open.
Reminder:
When you voltage test in the power board
in the primary section of power supply
use hot ground. Do not use the hot ground
when you voltage testing the secondary
power supply, mainboard and controller
because it will cause of damage
semiconductor. For safety use cold ground
for secondary, mainboard and controller
board.

Compaq presario f730us is forming vertical & horizontal lines on the lcd


Normally this is due to several different things. I can give you a few suggestions but you will have to do the detective work. First this can happen because of a bad video card. This can also happen because of a bad connection to the mainboard or a bad cable from the mainboard to the back of the LCD. Last but not as likely is just a bad LCD. Try hokking the laptop to an external monnitor. You should have a 15r pin connector on the laptop to connect a standard monitor to it. There should also be a Fn key that allows you to activate the external part of the LCD. You have to know which key to hit with the Fn key to activate this feature. You can also try to hook up the external monitor before starting the laptop. This normally makes the external monitor activate. If you see the lines on the external monitor as well then its the display adapter not the cable or connection. If the external monitor is clear then try the video cable. The least expensive and easiest to replace is the video cable. Check to see if it has a good connection to the mainboard. If you still have a problem then replace the cable. If that doesnt work and you are really fond of this laptop try replacing the mainboard (unless your video card is replaceable on the motherboard then replace the video card). If you dont want to sink a lot of money into the laptop and the video cable doesnt work then run it on an external monitor. If you need the portability of a laptop and you have determined that the mainboard is bad then you might just replace the laptop and transfer your data. Hope this helps...

Do I need a video card for this mainboard?


Since you have able to connect your monitor to the board it means that it has a built in video on the mother board but there's no display on the screen if that's the case there's a possibility that the built in video is not working fine, so I'm suggesting you get a AGP video card because its really better not to use the built in video.
