OC gone wrong, help me find the problem?

The CPU fan is connected fine, and spins. Everything that can spin, spins.

What I don't understand is a) why does the computer reboot after a few seconds every time, then stay on with no display/POST... and b) more stuff about no POST.
 
Christ this is making me think I might just keep my i5 at stock when it arrives :| hope you get this sorted bud x
 
If you want to keep an i5 at stock, I don't really see the point in buying the K edition. At least, that was my thinking.

Google tells me that the power supply might be blown because the fact that it powers the fans/drives etc doesn't mean it's able to put out all the types of power for the other components.

The LAN port lights up when the machine is powered on, but none of the USB ports work or seem to be powered. I find this odd. Does this suggest PSU failing to anyone?

At the moment a 2500K is actually cheaper than a 2500 on OcUK so you might as well get a 2500K whether or not you plan to overclock.
 
If anyone is wondering, the motherboard was found faulty, so my spidey sense was correct.

That's balanced out by the idiocy of trying to install my old 1.65v RAM into the new mobo, which supports 1.5v RAM. Didn't realise until I had a mess around inside the case and saw it written on every DIMM slot.

D'oh.

Glad you got to the bottom of it, however the 1.5v is just guidance, most modules are 1.65v and work fine with SB. Infact many of the SB "tuned" memory is 1.65v. There is zero evidence that running 1.65v is going to do anything bad to the system.

Hm, you may be right and I may have just blown the module in the OC fail (though I don't see why... power surge may have taken it out when I turned EIST off?)

Either way, replacing 1 stick of XMS3 1.65v with 2 sticks of Vengeance 1.5v worked. I had to reinstall windows because it insta-BSOD'd every time Windows started up. Maybe something to do with old ASUS motherboard drivers clashing with MSI components? Either way, this MSI board is better, and the one click OC has got me up to 4.2GHz on the 2500K in a split second. If I'm feeling brave, I may push it again. But if you read up you can understand why I might just leave it at that.

Also, it really does boot up in about 3 seconds. So many times I wanted to get into the BIOS and was like "WHAT, Windows login screen!?".

Could have been AHCI settings, if windows was installed with it turned on and the new motherboard was set to off, but hey, a fresh install never does any harm :D That's great about the boot times too :)

I've never overclocked, but I want to give it a try - but these horror stories put me off, as I only work part time (money shortage!) and couldn't live without my computer for any length of time (yes, I'm the kind of saddo you see on holiday paying 50p for 15 minutes computer usage in hotels :D)

D'oh. Should have asked here first. Ah well, not too much data was lost. Also, don't be put off. This is a problem with the new motherboards, so the title is a bit misleading but it just happened to fail during the overclocking process. I, like you, felt pained by my PC being taken away from me, even with my custom built gaming desktop replacement notebook right by my side. But I overclocked my 2500K to 4.2GHz on return, the minimum I intended, and it's stable.

Tl;dr: if you want to oc, do it.
