Computer doesn't want to boot correctly.
#1
I'm having a strange problem, and it's preventing me from using my computer.

Okay, for a few months, my computer had a problem where I would have to leave the power supply on (but the computer off) for about 1-5 minutes, and then press power for it to turn on, otherwise it would turn on, but the harddrive wouldn't come on, and I wouldn't get the little "beep" that happens each time, and needless to day, the computer wouldn't start up, despite being on. However, like I said, leaving the power supple on for a little bit before pressing power would have the computer start up just fine. I'm hoping that going by that method isn't what eventually led up to my computer's current state.

Now, when I do the same thing, it seem as if I have to leave my power supply on for an even longer time, or it will turn on, but not start up. However, NOW when I do it, the computer will start up, load windows, and ect. But will only work for about 5 minutes before the whole computer just freezes altogether. It's most likely (or definitely) a hardware problem, and not something going on with Windows. My Hard Drive appears to be just fine, considering Windows is still there, and everything loads up just the way it did before. And when my dad and I took the power supply to Circut City, they did a test on it, and the person told us the power worked just fine, so I'm not sure exactly where the problem is.

One thing I've noticed however, is that the green LED on the front of the computer, on top of the red HDD led, seems to remain off. I was pretty sure that despite the computer being on, it may have not shown up. I might be imagining things, however, because it would make sense for it to be on considering it's probably the power LED. If this happens to sound familiar, then by all means please let me know, but otherwise, don't read too much into it. I could be hallucinating.

A solution to this would be greatly appreciated. I've done some Google querys to see if anyone's had a similar problem to mine and solved it, but no luck.

Thanks.

90% chance it's your power supply, 10% it's your motherboard. I had a similar problem a few months ago. (It was the PSU.)

Personally I wouldn't trust anybody at Circuit City to test any part of a computer. Wink

You can test your PSU yourself to see if it's the problem or not. Leave your computer off for an hour or so to let the PSU cool down. Then get a multimeter and check the voltages on the +5V and +12V rails while the computer is booting up. (Red is 5V, yellow is 12V, black is ground. Use the ground closest to the voltage you are testing.) They should be within 5%. (So 4.75-5.25 for the +5V and 11.4-12.6 for the +12V.) If they are lower or higher, your PSU needs to be replaced or repaired.
