I usually keep my PC open at night, and it's been fine for the 2 years I've had this machine. This morning, however, I found it turned off. When I pressed power, it kind of stalled. As if it made an attempt to open but failed. Then when I pressed power or restart, nothing happened. So I unplugged everything, replugged it then pressed power again, but it still stalled. I tried unplugging the power and plugging it in again and still, it stalls.
I doubt the problem is my Hard drive, as it doesn't even boot Dos or anything. The screen has power but shows nothing for the 2 seconds that the computer is on. Please help

mine is more guess, i've had the same thing happen to me in the past and i ended up buying a new pc.
Might be worth trying to borrow a proccessor ( on that's compatable ) to test ?

Hmm... well what happened to your Hard Drive(s)? I've been stupid enough not to back up anything

Is there any beeping noise from your system when you start it? Do you see 4 lights on the back of your system (the MOBO lights) and what color are they?

I hear the drives that kinda start to spin, a kind of "Whuuurrrrrr" and my screen give the kind of static-ey noise it usually makes when it starts up. There are no lights on the back, and I don't think there ever were any, but the lights on the front of the computer turn on for under a second: The one next to a kind of cyclinder turns on yellow and the one next to a lightbulb turns on green.

So it does power on but nothing comes on the screen? Saying that 'it stalls' doesnt help much cos that doesnt really mean anything.
Does it beep at all?
Does anything come up on the screen?
After the HDs wrrrr up do they go quiet or entirely off or start clicking?
Do and lights come on and if so do they stay on or go off?

Hmm, turns out the computer wasn't even on all night. My dad went down and turned it off
Kid - no, it tries to turn on but fails. No beeps. The Whurrr dies off after about a second or two. The lights on the front are only on for a split second. Nothing comes up on the screen although the screen does have power.

What does it fails mean?
Does it come on and then go off? Do any of the things above happen before it goes off? Or does it simply do nothing at all when you turn it on?

Alright, order of events:
-I press the "Power on" button.
-The lights turn on then off.
-At about the same time, I hear the Whuuurrrrrr sound that dies off almost at the same time as it started.
-The screen makes the normak static-ey noise that it makes when it turns back on.
-The computer turns off, and I hear or see nothing more.
All this happens in about 2 seconds.

Try a different one. You can get them very cheaply now, make sure it is the same or above the power of the current one, 350W or above really.

Yeah it sounds a lot like the power supply. What I would do is take out everything, including your processor and heatsink and ram (anything connected to the mobo) And plug the mobo only into the powersupply, and press the on button. If nothing happens its either the powersupply, or a bad switch, but a switch wouldnt stall out in the middle of the night so i say try a new power supply.
However, there is a way to test the power supply by itself, because the mobo could also be faulty.
*Use at your own risk..but it should be fine*
Take out your power supply, and leave it unplugged. Do this at a table or something. Take a paper clip. STILL MAKE SURE ITS UNPLUGGED. And insert one paper clip in the motherboard power connector, (the one with 12+ holes. The large rectangle one.) Plug one end into a green hole, and one into a black hole. (The colors of the wires make the color) DO NOT touch the paper clip, and turn the switch on the back of the powersupply. If the fan inside turns on, then the problem is something else. If it doesnt, then thats your problem.
That might sound retarted but many tech support people have told me to do it, and ive been able to successfully test my powersupply last time because it was faulty. Good luck.

This may not help at all, but if you haven't opened up your tower and blown out all of the accumulated dust, I would do that too. Just get a can of compressed air and get all the crud out. It's helped me greatly in the past when I've had similar issues. Just make sure you ground yourself before opening up the tower - the last thing you want to do is zap something with static electricity and compound your problem.

Thanks for the help. If the problem is indeed the power supply, is there any chance that it took out the Hard Drives with it?

There's a possibility that some data might have become corrupted, but from what I know, it's only data that was being read/written at the time of the power supply failure.
But I doubt it's anything a drive-recovery program can't fix.

Yeah, dust heats things up faster. The only chance of the power supply taking the Hds with it, is if there was some outburst of electricity, but theres a more of a chance the powersupply just died from over use. 2 years non stop on a powersupply can do it to ya.

Well, while we seem to be on the topic, maybe you folks can help me with my computer problem....
It seems that my computer likes to shut off on me as well, but not immediately after turning it on... it's usually when it's working on something pretty hard.
For instance, I was rendering a video the other day, and it would get about 3/4 done with the render and then just power off... I tried it at least six times until I took off the case cover and directly pointed a large fan into it.
Now, I figure that it must be overheating. But the fan on the motherboard and the fan for the power source seems to be fine. The fan on my video card, however, has stopped working.
So my question is, would it be that fan that's causing the overheating? It seems a little odd that a fan for the graphics card would cause the entire computer to shut off, especially when rendering isn't exactly a very "graphical" process.
Anyway, I know that either way I'll need to replace it, but I wonder if it is that, or if it could be something else entirely that is causing the power-down? Furthermore, is it possible to just buy a new FAN instead of a whole new video card?
The type of card itself is: NVIDIA GeForce FX 5600SE

This is a problem me and my family are experiencing on our second computer. I believe it has something to do with the processor overheating, since we have changed almost every part of it to make it work excluding the motherboard and processor fan.
It would be nice to fix it though.

nitroviper, anything overheating could cause the PC to shut down because motherboards have different precautions which work automatically when something fails, to turn the PC off. First of all get speed fan, its free and it tells you all your temps on your PC.http://www.almico.com/speedfan.php
Second of all, get a VGA cooler, http://www.newegg.com/Product/Product.asp?Item=N82E16835118216
That one will do or you could look elsewhere for cheaper ones, but until you get one i wouldnt do any intense gaming on it, because it could cause it to burn out. Good luck.

Pooky I'm afraid you're getting a lot of bad advice mixed in with some good...
In other words, don't do any of the stuff people told you to do in the previous posts.
My power supply died on me a month ago. Here's how I diagnosed it:
1. Open your computer. the box where the power cord plugs in is the power supply. Make sure the switch on the back of that is off. Leave it plugged in though.
2. You'll notice that most everything is connected to your power supply in some way or other. Disconnect all of the stuff from the power supply, noting how it was set up if you don't think you can figure out how to plug everything back in. Sometimes having too many devices on one cord will not provide enough juice, so when you eventually hook everything back up, don't go plugging everything in to one cord. Like I said, just observe how it was originally set up.
3. Now, as you unhook things, you'll notice that there is a gigantor connector to your motherboard from the power supply. Unhook that as well.
4. Grab a paperclip, un-bend it.
5. Stick one end of the paper clip into a hole on the motherboard connector that leads to a green wire. Stick the other end into a hole that leads to a black wire, not white, which is what Zea said. Green and black. You'll notice that there are more than one blacks. Any one will do.
6. Hold up the motherboard connector with the paperclip in it so it's not touching anything else. You won't get a shock or anything if you touch it, but for things to work properly, the paperclip can only make connections to metal in the two holes it's stuck in to.
7. Flip the switch on the power supply. Does the fan in the power supply spin? If not, go by a new one and replace this one. They're only like 5 bucks.
8. If the fan does spin, then we're probably all stumped. Try taking your RAM out and putting it back in if it turns out your power supply is fine. I've known RAM to short before.
9. Oh, and the rest of your computer is fine.

Yep it was the power supply. Thanks for all your help, we went out and bought some fancy 400 watt Antec one and it works fine now, no damage to my files. Thanks

All this messing about with paperclips is not only dangerous but wont really tell you anything. Quite often PSUs do not just stop working entirely but act unpredicatbly or voltage levels on certain lines change from their designed values. When its so cheap to get a new one even if you dont have a spare one about there is little point to it.
Anyway, glad to be of service pooky.

This kind of reminds me of my cd drive problems (they're fixed now, though).
I'd be installing a program that takes something like 5 discs, and I'd notice the progress would get slower...and slower...and slower until it begins making that "CHUCK" noise. After about 2 minutes of no progress, the installer shuts down and the computer says "Cyclic redundancy check error."
Turns out it was due to the drive overheating, so between CD's I'd take an ice pack and put it on the metal parts of the drive.
Anyways, glad to hear that nothing was lost. 3 cheers for Kid for solving his problem!

I've also heard that it is relatively dangerous to purchase a low priced power supply from "Vendor X," as often they have relatively low efficiency, often times do not run at their specified wattage, and, as some poor chap in the Dell Support Forums said, "They WILL fry your machine."
I've since figured saving money on the PSU isn't worth it, as an extra $40 could mean the difference between continuance or cessation of existence for a PC.
