Why is this happening?

Specs: Linux Mint 7/Windows XP.
Okay, so I have an Emachines desktop that I purchased in 2005 (It was the pre-loaded one you could find at Walmart or etc for $500.), sometimes when I press the power button the computer will turn on, but it won't boot, it doesn't give any beeps or etc, so I take the cover case off and then try and restart it and sometimes that works, it's like it will start and the fans will spin faster than normal and it won't boot, but other times it'll boot fine and the fans inside it will be at a normal pace and they will be at a quiet noise level instead of spinning very loudly, if that makes any sense?.

The bios exerts control over the fan speed. So if the fan gets power but the bios doesn't kick in then it runs at maximum.

I had that exact problem with another emachine. Swapped power supply and that didn't help. I fiddled around with it a little more but concluded it was the motherboard

Oi, that blows. Cause the warrenty is expired, I think. Thanks for the info though. Is there a quick fix or something I could do to fix the problem when it happens?..Since I can't buy a new mobo right now.

Worth a try: Power off and disconnect the AC. Open it up and reseat the motherboard power connector.

Yeah, you can also disconnect the drives and remove any added cards except video and see if you get a normal posting screen. It doesn't have to be the motherboard--that's just my best guess.

Given the time you bought it and it is still running......

The Bestech power supply used in E-machines has, or seems to have a built in end of life function. When it goes it can take out everything. mb,hd,cdrom,memory,cpu.

If you get your posted problem fixed, look for another power supply and replace it......ten minute job....and then get another few years of service from the computer.

It doesn't have to be an expensive high end PS just not another Bestech.

I'll keep that in mind about the power supply, I mean. Usually what I'd do is open up the case, leaving the cover off, and push down on the stick of Ram and reconnect the Processor fan connector, and then gently press on the power button and it would start fine. Sometimes that doesn't work though.
