Stupid computer won't turn on without an ATX reset!

Does anyone know what my problem might be?
My desktop computer currently won't turn on unless I do an ATX reset. It doesn't even POST beep. But if I do an ATX reset then it's fine. I can't even restart it without the problem occurring.
I have recently changed the hard drive, but it did this before then. And I have Ubuntu, but it had Windows XP before on the old hard drive so I don't think that's relevant; I just like telling everyone I use Linux.

I had this happen (you mean resetting the mobo right). tested everything else, eventually just swapped out the mobo. done."If you really want to hurt your parents and you don't have nerve enough to be homosexual, the least you can do is go into the arts."0

Can you recall if this started happening after you made some hardware changes - perhaps after adding memory?
The symptoms seem familiar, and IIRC were caused in my case when using two or more sticks of RAM which weren't well matched. Solved by changing the memory, and I never really figured out why it behaved like that - best guess was that a BIOS reset made it use fail-safe defaults, while during a normal boot it would try to auto-detect CAS latency and all that stuff - and get it wrong...0 -
nothing had been installed/replaced.
it was a relatives' Dell, hadn't been touched from new."If you really want to hurt your parents and you don't have nerve enough to be homosexual, the least you can do is go into the arts."0 -
When you say ATX reset are you resetting using the button on the front of the computer, or resetting the bios usng the clear cmos jumper on the motherboard?0

Take power cable out.
Hold down power button for as long as I can be bothered.
Plug it back in, and it turns on fine.
I'm not entirely sure what a "cmos" is. And it hasn't always been mine, so I'm not sure what's happened to it.Murphy's No More Pies Club #209

Dell's answer to this is to replace the PSU, then mboard if thte PSU does not fix it. Seen it many times on Dells.
There is a problem with a wide variety of PCs around the Dell GX270 and GX280 (era (2004/2005???) which has to do with leaky capacitors. These capacitors bulge or/and dome Dell will replace the MBoard/components for free if that is the case. Other companies including HP also bought the same capacitors. These capacitors should be totally flat on top. Failure of the capacitors can damage the cpu, mboard and memory.
