My best guess is a dead hard drive.  Does the computer make it past the Post (power on self test) screen.  Does it attempt to load Windows, does the clicking start with HD access or does it start as soon as you turn the PC on.  Is anything displayed on the screen at all... until the clicking starts.  If your computer makes it past Post then I'm going with my initial gut feeling that your hard drive died on you.\n\nOf course, I've never had a motherboard short out on me so I have no idea what that would sound like... but it could be, I couldn't say.  Once again, this is one of these catch all problems where just about anything mechanical or electronic could be causing the noise.\n\nWell, since nothing works, this is going to be hard to diagnose.  Best guess is still a hard drive but now I'm going to toss in the processor, memory, GPU and well, any other hardware in your system.  Start removing components one by one and see what happens, save for the processor, I've never tried to boot a system without a processor but my guess is nothing will happen.  If that doesn't work, you're right back at square one.  Here's an idea, take your hard drive out, plug it into another computer as a slave and see if it at least works, don't do anything to it, just see if it is recognized, if it is, not the hard drive.  If you can rule out the hard drive you are looking at a dead motherboard and/or processor which will have to be replaced at least.  If the motherboard is fried, you'll have to check the other components to see what is good and what is not.

This sounds as if your power supply on the PC itself went bad.  Especially if you have checked all your power connections, and you are still on getting power to your system.  \n\nyou may need to contact E machines and see if your system is stll under any warranty.  If you have any Geek friends, have them check it out to make sure its the power supply, and not the motherboard, memory, and/or processor.

are you powering up with your battery alone, or are you plugged into an outlet?\n\nhow old is your computer? is it worth spending money to fix it by going to a computer repair shop?  are your files very valuable?

you can hear when computer is on - there's fan, and hard drive. Plus disk light on the front.\n\nIf you turn the switch and nothing happens:\n- make sure there's no second switch on the back of computer.\n- make sure there's power in the socket  - plug desk lamp into it. If lamp works, and computer doesn't, either power cable is busted, or computer's power unit. Cable can be bought, power unit can be replaced in a shop.\n\nSometime monitor or printer uses same power cable - if it does, use it to see if that's the problem.

You didn't give enough details.  How far into the bootup can you get?  Is it a power problem?  Is the light on the front of your PC on?  Is there an error message on the screen?  Does anything show up on the screen?  What happened right before the problem started?  Was some new hardware of software installed or removed?  Do you have virus protection?  Do you have your Windows recovery disks or the original Windows CD?  Post the question again and include as many details as possible.  Computer problems are too complex so anything you can add will help.

It will do this if the computer is not properly shut down. Let it go into safe mode, and use the start>shutdown function from there. If it insists on going to safe mode and won't start any other way (after you pick normal start) then there is a big problem and you may have to reinstall windows.

"(shut all electricity off from your computer, i.e. pull the plug)"\nLol thats after you've turned off your computer that is. Don't ever unplug/turn off the computer with windows running if you can help it. Doing so might result in damaging system files preventing windows from working properly or starting at all.\n\nIf a reboot doesn't help try deleting your internet cache. If your using Internet Explorer open it up and click on Tools - Internet Options - Delete Files - Ok. Its also got a button to delete cookies that may help. Failing all that try getting a new copy of Shockwave flash off the internet (macromedia.com?) and installing that.

I had the same problem. Is was an electrical surge from my power source. Caused by  the fan motor in the processor. I had the motor replaced and it is back to normal.

If this is a problem that started out of the blue without you touching any of your settings, chances are there is a problem with either your motherboard, graphics card or processor. I had this same problem and it turned out that my motherboard had burnt out.\n\nI don't know how old your computer is but if it is more than 3 years old, chances are it is burnt out and you will need to replace your base unit.

multiple things could be the problem, you'll have to do some troubleshooting.\n\nFirst I would check that the monitor is plugged in correctly and powered up. There is a plug, ususlly blue, plugged into the back of the tower and leading to the monitor. two manual screws hold it in place. untighten the screws to see 15 pins. make sure all pins are intact and not bent. plug it back in tighten screws, power on pc, give it a second and see if it works. if not... \nNext I would check the monitor on another computer or try another monitor on the first computer. If the monitor is not fried, its likely you have a video problem. \nIf its a video problem, you are going to need to get a video card. ask at your local computer store. buy, or borrow one from a friend for testing. you might want to open your tower first to see what kind you need.\nGet some canned air and a small screw driver. \nBefore you open the case check to see if you have onboard video or a video card. You can do this by seeing if the Video plug(vga 15 pin same as before) is located behind your I/O shield (where the printer port, mouse keyboard and usb ports are) which would mean its onboard. If it is in one of the long horizontal slots, its a card. \n\nunattach the VGA cable and Open the case. Its usally either a screw on the back and then sliding it off or a handle that you can use to pop it off.\nBefore touching anything make sure the power is off, but the computer is still plugged in and put a hand on the metel case to ground any static electricity in your body. esd can damage your mobo. \nplug your nose and close your eyes and blow out that dusty mess with the canned air.  \ninside is a mess of cables that can be scary but bare with me you are looking for a speciffic thing. you should see the power supply with all the multicolored cables running to the cd rom hard drive and other stuff. Then there is likely some IDE cables (flat ribbon cables connecting the motherboard to the hard drive and cdrom.) on the mother board there will be some slots (usually white) that correspond to the slots on the back of the tower. in these may be the video card, if so you have a PCI video card. If the card is plugged into a similar slot that is shorter, set back more, closer to the inside of the motherboard and probably brown or blue (also corresponds to a slot in the case usually the highest slot), it is AGP. If you have onboard video just see if you have an AGP port so you can get an agp video card. (note there is a new technology called PCI express but unlees you bought your computer in the last 6 months don't worry. ill assume you haven't otherwise you'd just use your warrenty)  \nso get yourself the correct video card (agp or pci agp is better).\nPull the old one out (unless you have onboard video) \nThe long piece of chrome metel attached to the video card is bent at the edge and there is a screw in the top. (or there is a clip over all your expansion cards) unscrew or take this loose. agp cards sometimes have a plastic clip on the back to keep them from popping out, unclip this.\npull strait up on the card, some force may be required but don't break it. handle all circuit cards by thier edges only as much as possible to avoid esd. \nUnpackage the new (or Known good) video card and insert it the same way you pulled the old one out. make sure that it is seated well. put the screw or clip back in place and close up the case. \nattach the cable to a known good monitor and power up.\n\nif this doesn't change anything, its likely that your motherboard is freid. if this is that case you will need to have a professional work on it for you or just buy a new pc.\ngood luck.

Could you have blown the fuse in your plug?  Replace the fuses in both the computer and monitor plugs.  It is possible to buy a plug that prevents power surges reaching your computer.  \n\nYou may be concentrating too much on the coincidence that the warranty ran out at the same time as the problem started.  \n\nYou may have caught a virus and need to use your anti-virus recovery disc. \n\nYou may need to use your Windows recovery disc. \n\nAs everyone has mentioned already we need more info.

You won't be able to tell anything until it is turned on. Check all the drives and make sure they are working, the amount of memory, hard drive (check this in the BIOS). Listen for strange noises with the power supply fan, CPU fan and hard drive.

Check the fans and make sure they ALL are working. If you have a CPU temp utility, use it. Try starting in safe mode and see if it is still happening.
