24pin ATX connector melted into Socket!

I've been getting flaky performance lately, to the point where it was BSODing, not restarting without BIOS Reset etc. The culprit seems to be;

Notice the burnt pins on the 24 pin connector and the melted plastic in the socket. I've ordered a new PSU but am hoping I can clean melted plastic out of the mobo socket perhaps with a scalpel? Anyone done this before or got any suggestions?

Well, I've had a go and had limited success, it's such a small area to get into that I ended up using a pin and magnifying glass to see what I was doing, it's a little better but nowhere near perfect. Looking around the web it seems to be a common problem when the PSU is overloaded by high end video cards, which would make sense as i've been testing out water cooled 470gtx SLI and overvolting them. The PSU is (was) a Coolermaster CM850, I thought it'd be up to the job. :confused:

I suppose the real issue now is do I try out the replacement PSU on the existing motherboard or get another one?

I've just received a new PSU, an Enermax Revolution 1250w, that should be man enough for the job,

. Now it's just whether I risk it an see if the mobo is ok or bin it and get another, the thought of spending another £200 is too much to bare.

I put the new PSU in last night. For some reason windows had corrupted so I reinstalled it and got a lot further down the line.
I could clock the cards and pass furmark xtreme Burn test for 30 minutes, 850 core on both cards which I was very happy with.
However, I keep getting an issue where the PC screen goes blank, sits there for about 10 seconds and then restarts, this is at stock clocks, on the desktop.

So, new PSU, clean Win7 install and still issues, I'm thinking the motherboards hosed?

New motherboard sorted it...this month's been very expensive.

Thanks, I'm not sure whether to RMA it or just cut my losses, reading up seems to give conflicting reports as to it being the fault of the motherboard or the PSU, no harm in trying I suppose.
