A while ago i took out a memory card to check if the extra mcard i have also work. It didnt. And when i put back the original card the computerefused to boot up and i saw nothing onthe screen. Theres a little green light onthe motherboard,does this mean the motherboard is not broken? And the fanstil work too.

Its an asus a7n266-vm motherboard

Hope this helps.

Did you make sure you installed compatible memory, and it is installed properly?

reseat all mem sticks/cards

yes. The mem cards thats in the pc were the once that booted up before. I was also advised to remove the mem cards and reseathem again. I hope that works cause now i have to remove the graphicard in order to remove the one mem card. Thank you for every ones help. Iwill bemencely greatfull if some1 can help.i got this realy nice math game for my brother and iwant him to use the computer to support his gr 3 schoolwork this year. ..so does it mean thathe motherboard is not broken if theres a green light?

It may just mean it's getting power, check the user manual.

The fans and the light on the motherboard all come on? I would check the Video Card and make sure it is seated properly. Then check the VGA cable to the Video Card and make sure it is connected property. Finally check to be sure your monitor is plugged in and turned on.

Nicelady it could be a few different things. The green light on the motherboard does not have a universal signifigant meaning that I am aware of..for that the pc uses beeps to indicate the type of system problem (when I removed my hard drive it did it often). When you talk about removing memory and not booting I automatically think that the PC cannot find an OS to boot from. This is easy to fix...On my computer I press f2 while it is loading the OS to enter CMOS set up. There you can see soemthing called the boot sequence and manipulate it to boot. There is prolly an easier way to get it to kick on though. And the OS not being found as it boots is not definetly the problem..just probably is.

Have you tried jumper cables?

I would try booting the computer then plugging in the card/stick as it may be trying to boo0t from the card/stick rather the the hd.

Here, I just thought about it for a minuete..and here are some things you can try...

If the OS is not loading and you have been handling the motherboard you might want to try checking the cables that connect to the HDD (hard drive) the HDD is usually in the bottom bay of the tower underneath the other drives and it is the one that cannot be seen from the front of the case(like the disk drive, floppy and zip drives ect) there should be two cables (power and data cable) connected to it..check those two cables...Do you hear the HDD spinning while booting?? The data cable also plugs into the motherboard...check that connection as well. The other cable should come from the power supply and is fixed to it...not connected and should not need to check it.

Also you say memory card...you are talking about a DIMM card that goes into the slots on the motherboard correct...for RAM...right?

The green light might be an indicator that it was not properly seaed in position. To install a DIMM card. You spread the levers on the side to open the clasp where the card is placed. These should fall into position when the card is placed back into its spot. Also DIMM card related is .... some motherboards have DIMM slots (place where RAM cards are placed) configured for dual data transfer and must have two cards (one in each row) otherwise its counterpart (side by side) will not work. The green light may indicate that the DIMM cards are not properly seated and could prevent the OS from booting. Also check that the apropriate edge of the card is making contact with the motherboard (that it is not flipped the wrong way).

If these things do not work ... it is back to what I originally said.. if the problem really is that the OS cannot be located during the boot sequence you might want to try booting from a disk. If you wanted to do a thurough job you can look at the boot sequence (even if your PC is having problems loading an OS) this may not do you a lot of good becuase you don't know what your looking at. One of the last places the system will check for an OS to boot from is the disk drive. If you have an install or restore disk you might be able to boot from that...

bad Business being in a live Machine!

thing is I never seen anything in the post about it being open in the 1st place, and a lot of computers have ports in the front/back for sticks/cards.

When I try to boot my comp after forgetting my card plugged in it will attempt to boot from card and fail, same with a stick.

If it is how you say then yes my post is invalid.

Oh yeah... if you try to boot from a disk and want to keep the data on your HDD it may not be a good idea becuase eventually it will re-format the HDD and write the new OS onto it at some point...just so ya know.

Also in the even you wanted to try to boot using a different OS you can get a free OS (it is Linux) from the following web-sites... www.novell.com/linux/suse or www.redhat.com or www.turbolinux.com or www.slackware.com are places you can get a copy of a new OS to try booting from. It will probably help if you have a second PC..which I am guessing you have to be able to talk about a PC issue online.


Let me know how it goes... I just got these sites from my software fundementals class.

Ive replaced the graphicard and the memory cards. Computer still.dont work. Only sound is the breezing fans and the little green light onthe board.theres nothing onthe monitor either.hm it remains a mistery.the monitor works fine on other pc.so it must be the?

Is the light on the MB flashing? Is there a speaker in the case? If so, is it connected? If not, you can contact some local computer stores to see if they have a "Mini Onboard Speaker for a Mother Board" or you can buy one online for only a couple dollars, but the shipping might be high.

yep,but that doesn't hold good for Internal RAM and expansion-Cards!

its a tiny bright green light onthe board,it doesnt flash. Ididnt conect external speaker however soundo work. I moved the output from the graphicard to the onboard and the computer made some beeping sound. When the pc was workin i changd the bios to work on the graphicard.however at current no view onthe monitor. It apear thathere is power on the board and nobootup.nothing on screenot even error mesg.
