I had a program running and went to insert a DVD.  When I did this, the computer shut off.  I went to boot it back up but heard a "pop".  Now, the green light is the only thing comming on.  The green light comes on on the motherboard also.  No fans start running and there is no beeps or anything....just the green light.  Did I fry something and what could have been the cause?  Thanks in advance.
If the green lights are on then it is recieving power. However I think the pop could of been the power supply that just ended. Do you have another power supply to try out.

What the WATT on your power supply?
How long you have had it?
What devices are inside? Ex. 2 Hard Drive, 1 CD Drve etcc...


1. Open your case and see if there is any burnt smell. Usually if something pops or fried inside the computer there should be some sort of odor.

Thanks for replying.

I think the power is 450 watts.
I built this computer last year so it's about 1 year old.
I have 1 SATA 250 GIG HD.
1 DVD player/cd burner
1 DVD burner
1 floppy

I didn't smell a burnt smell.  What could have caused this?There are 2 simple things that can cause a computer to suddenly pop. One is if the computer has been straining the power supply. ex Trying to take more power then the power supply can give.

Another reason is if the power supply accidently surged into the computer, ex accidently giving it to much power to a component and accidently frying something. Storm, or to many ELECTRIC outlets.

Do you have a old computer to test out the power supply? If you plug in the power supply to another computer and it works then it is another issue. Check the power supply first.

Also are you USING a surge protector and is it grounded?


If the power supply works then you have to test your computer hardware to see if it is a damage hardware. the basic you need in the computer is a CPU and RAM just leave 1 RAM in and the CPU unplug everything and remove the hardware and try to start it up. If everything seems normal then it is not any of those 2 components. You can slowly add each piece again 1 at a time to find out what kind of hardware could have failed.

I never actually had any hardware fail on me other then the power supply that poped on me when I turned it on one day.OK.  I'll try that when I get home.  Thanks.  One more question.  If it is the motherboard, how will I know it is the motherboard and not something else.  How can I test the motherboard?OK.  I tried to just do minimal and the same thing happened.  I noticed my cpu fan/heat sink was pretty dusty.  Could I have over heated the cpu or motherboard or both?  I have a fan on the power supply and a smaller fan on the side of my case.  Should that be enough or should I get another fan?BTW, if I do need to buy a new motherboard/cpu bundle, any suggestions on what type of socket to get?I am sure someone here can recomend a better motherboard and CPU if you need to replace it. I am not the kind of person that goes for the latest and greatest. (*my screen name*) There are alot of people here who are more updated... I mean more knowledgeable about motherboards that are out in todays market.

Sorry for the abrupt sign off yesterday. I had a Java class that was about to start so to answer your questions:

1. To Check your motherboard you need just a CPU and RAM. when you turn it on everything should here the computer just running and starting normal. If it seems normal then plug in your video card next. It wont load anything but at least you can see the BIOS screen and know it is working.

If the comptuter fails to start property. Check the RAM and CPU and see if any damages are on them. I am sure no one carries an extra CPU around and I do not want to make you go out and buy something if the motherboard is fried UNLESS you plan on buying a motherboard that can support the same CPU socket.

2. The CPU fan should be adquetly enough to cool the CPU if you used the same one that came with the box. (Under normal circumstances) I have no idea where you place your computer. is it on the floor? Do you make sure that the back is not to close to the wall so it can ventlate easy? The fans you have should be enough unless you have a very powerful video card with alot of fans built right into them.

3. Motherboards nowadays are built that when an overheating is detected 2 things can happen. It will automatically reset the computer for you many times and drive you crazy or it will just completley turn off on you without warning. The pop could be an indication if a hardware failed on you when you were using it but this will be a first for me. It might be pretty hard to diagnosis without visual. trying to picture the computer in my head.
I took it in to a shop and they said it is the power supply.  Only thing is that my roomate wanted it fixed now and is willing to pay them $150 for a new power supply.  I told him, he's nuts cause I could do it for like $50.  But, I guess problem solved.BTW, thanks Windows98 for your help.   I wish I could get $150 for changing out a PSU.
