    To me it looks as though your PC was fine with the none K CPU, uve then changed the CPU and its not fine...first port of call for me would be..is the cpu i've just installed OK. Looking at your rig you have a decent PSU and if it wasn't giving you problems before its very unlikely a simple cpu swap would of killed the PSU.

    ^ As stated above, try optimized defaults in bios, it could be something as a setting somewhere that you may of missed.

    If you need someone to test it for you I don't mind.

    Have had a bit tech member do the same for me in the past :)

    Obvs try everything else before you resort to it though.

    Can you not get the non K one back to test the system with that? it really sounds like the new CPU is at fault

    Offer much appreciated, I'll let you know.

    It's over in Ireland, so a bit of a hard one to get back.

    Well unless you've damaged the mobo changing the CPU which is unlikely I would suspect the new CPU

    Have you tried resetting the BIOS? If the CPU is at fault, it's very unfortunate as those things do not die often unless you're doing some crazy overclocking with silly voltages.

    I think you can RMA directly to Intel though so that's good. If not, try to get the receipt off of the guy who you traded with.

    Any chance of putting a spare HDD in and doing a fresh windows install, might be the OS not liking the change in hardware.

    Long shot I know but once you have eliminated all possibilities

    Okay, loaded optimised defaults in the BIOS which resulted in an instant crash on the reboot due to the power surge problem. Effectively, the problem is not a BIOS setting.

    I'll try a Windows install next - I have a spare 60GB drive kicking around. However, the fact that this issue is occurring before the machine even boots/gets past POST indicates to me it isn't a Windows issue.

    Cei - I've got an 1155 Pentium that you can borrow if you like, to rule out the board etc? I'm a bit to-and-fro at the moment given recent events, but if you're in London, I could leave it at my office reception for you to collect? LMK if that would help.

    jinq - any chance you can post it to me? I'll cover all your costs. Simply can't get up to central London due to commitments during the week. I will, of course, return it pronto.

    Apologies for the double post, but I've agreed to lend Cei an 1155 Pentium. :)

    So, after getting the CPU kindly lent to me, and sticking it in my rig with the exact same result, I worked out that the 3770K wasn't to blame.

    Cue yet another total rig disassembly all over the floor, and a root through my cupboards to find spare parts. In the end, I swapped out all the PSU cabling (I was using the fancy Corsair individually sleeved kit) with the stuff that came with the PSU...lo and behold, we had boot and stability. So, obviously the problem was in the cabling...somewhere. I then swapped each cable individually, finally pinpointing the 24pin ATX power lead. A single lead was delivering silly voltages, causing the power surges.

    Ultimately, everything is working again, and I simply have the RMA the cabling kit. And ask Corsair (nicely) for a whole tube of MX-4 I used up!

    OMG, I would have never thought of the modular cable oO. Well done guys and thanks to Jinq for its kind help.

    Yeah, me either. I was sitting there with the PC in parts around me, plus a cupboard of spare fans, CPU coolers, HDs, PSU cabling and everything when I decided to randomly try swapping over the entire cabling kit.

    On the plus side, the case is now ultra tidy!
