The computer turns on, but nothing happens after that. Everything is plugged in and the connections seem good. There are sounds, fans, and lights when the computer is turned on, and there are no unusual sounds. The monitor flashes a self-test message that the monitor is working and to check the pc and cable. Earlier I suspected a monitor problem and connected another monitor to the computer, and still nothing happened.

Re: computer turns on, but nothing happens
Yeah as donald said, But first try to reseat or clean your ram module its edge connector with soft eraser. But do this when the unit is off and unplugged from power outlet. Or place it to another bank with the same slot. Or your memory are already gone.
I had a similar problem with a Dell Computer. It turned out to be a bad memory card. If you have more than one memory card in the machine, take all of them out except for one. If that does not solve the problem, try swapping memory cards.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

This sounds like a definite power issue. This means that the problem could range from being as simple as the power button itself not working/disconnected to the power supply being dead.
Things to try:
1. Have the side of your computer open and press the power button. Notice if any fans start to move or anything that happens.
2. Do you notice the Hard drive light flashing at all when turning on?
3. Has anyone else been using or been close in proximity to the computer that could have bumped it, causing something to come loose?
4. ONLY if you feel competent enough, check the cable connections inside the computer. Make sure to disconnect from the wall for 30 seconds and reconnect before touching any cables inside. Leaving the cable connected allows the computer case itself to act as a ground to prevent static shock.
It seems like a motherboard issue. It heats up, thus is not able to turn on continuously. You may need to check internal parts embeded on the motherboard llike the fan and processor before you could know what needs replacement.
when you say no fan you mean the cpu fan or the case fan. the cpu fan is on top the cpu. make sure that at least this starts. if it does not start then shut down your pc immediately as it can burn the cpu.
it could be lots of reasons, but make sure that you have connected the power supply cables correctly to the motherboard. probably the motherboard may have a small led. check if that lights up. it means that power gets to the motherboard.
i would advice to find someone that has more knowledge.
I would recommend rechecking your connection to the motherboard. All wires from the power supply to board and making sure the front panel switch connection are correct. Also, make sure the power supply is compatible to the motherboare. even though a 20-Pin ps will connect to a 24-Pin board, it still does not work. Good Luck
As a hardware repair technician at a local university, I have seen the amber power light problem on quite a few Dell computers. If the machine is in warranty, Dell insists the power supply be the first thing replaced, even if it tests ok. If that does not do it, then they send me a new motherboard. Of the dozens of machines that have had this problem, only 1 of them needed a new motherboard. The power supply alone resolved the problem on all the rest. I have found this to be true on out-of-warranty systems as well.
If the noise is constant then it means the problem is either:
1: a Power supply issue 2: a motherboard issue 3: a keyboard problem
the latter of the three being the easiest to fix, try booting with your keyboard unplugged or even better if you have another keyboard try using it to see if that corrects the problem.
If the above does not work then you have a problem with 1 or 2, and in order to find out for certain you will need to test it, you can goto your local computer diagnostic store to see if they can check which it is.
Sounds like the power supply is faulty. Power supplies are very dangerous to try and repair, even for qualified technicians. I would also suggest not trying to plug it in or turn it on until the new power supply is in place. Faulty power supplies have been known to cause motherboards to permanently malfunction. Note: researching your issue, I came across several forum posts with complaints about emachines and their power supplies. The best way to solve this problem is to purchase a new power supply. If shopping online, www.tigerdirect.com and www.newegg.com are two places that specialize in PC hardware. A 400-watt power supply would probably more than do the trick for you. The cheapest one I found was $18.00. Make sure the power supply is compatible with your motherboard before you buy.
have u tried to unplug the power cord and open up the case aand unplug the power supply from the motherboard and then pressing the power button then plug the powersupply back into the motherboard and pluging in the computer and see what happens please keep me posted so i can help you more if needed ok best regards mike
try to remove all external device connected to your computer. just leave the keyboad, mouse and monitor connected.
if still a blank screen
remove everything connected to your computer (mouse kyeboard and monitor) restart if nothing happens
open your computer and remove all devices (hard drive, optical drives, memory... restart,,, you should be hearing beeping sounds indicating motherboard is looking for memory. try putting back 1 memory at a time and checking all mem slot. to identify if one of the memory could be causing the blank screen. if both memory will not work try to use known good working memory. if you dont get to hear the beeping sound using a known good working memory. your memory is the problem.
give me more info
