Can't boot - no power

Post by obsidian »

I've been having problems with my computer as of late, so I took the whole thing apart and put it together again, and now it won't boot.

As far as I can tell, everything is plugged in correctly. When I turn on the PSU, the mobo led light turns on, but when I press the power switch, nothing happens. No boot, no post, fans don't even spin, no indication that it's even plugged in at all except for the mobo light.

Any ideas of what might be the issue?

My guess would be that the case connectors are not in correctly. Either not connected correctly to the motherboard or they got messed up when you were moving things around, it has happened to me before.

Agreed with Ax

It curdled, and then I couldn't drink it. So I mixed it with some water, and it was alright again.

I am now sick.

Double checked my case power connectors. Plugged in correctly.

A bit of background...

I recently RMA'ed my mobo because of a bad onboard SATA controller. Details here:
http://quake3world.com/forum/viewtopic.php?t=17305

Sent it in, waited a few weeks, got a replacement today. Plugged everything in and then I get the problem as described above. Furthermore, I just discovered that 2 of the capacitors on the mobo are heating up unusually, just from being plugged in. So now it sounds like my mobo is the issue again.

Asus is starting to piss me off. My brother's in the process of RMA'ing his Asus board too (different model) because of random reboots and inability to boot up half the time.

Edit: Checking CPU now...

Just unplugged and popped HSF off and reinstalled. That didn't help, unfortunately.

Pull the power connector that attaches to the motherboard and reconnect.
And your brother's problem seems to be a bad power supply.
Just take one of the connectors that you use on a hard drive and see what volts it's outputting.
