Ok so about 20 minutes ago I noticed a weird smell while I was on the computer and what seemed like smoke coming out of the furnace vent. I thought that was where it was coming from! But something felt wrong, I rolled back in my chair and looked at my computer, something was very wrong. By that point I smelled burning plastic and immediately jammed the power button down to shut it down, I flipped the switch on my PSU and then turned off the power outlet (it's on a switch). I unplugged all the cables at the back and rushed outside. It smelled to high heaven at this point. Pulled off the side panel and started looking around, didn't see anything on fire (not that I was relieved at all by that). So it turns out that a power connection melted (molex > sata) converter. It was plugged into my hard drive. At this point I'm thinking I'm screwed. I'm concerned about turning the computer on again even though I've removed the cable and the drive. The drive underneath it got a little stained but the connections seem ok. I wonder if this could be due to the fact I recently installed extra ram? My PSU is only 500w but I really didn't think this would happen. Pictures included below, any advice welcomed. I'm thinking the drive is a goner but maybe I can copy the important data somehow if I can clean the connection?

I'm pretty sure i backed up the drive onto my 2TB but i don't remember the last time it happened.
