Just in case anyone was wondering, I did the Oven Trick and it did not work out too well for me..
My oven is pretty old so the temps could have been off also I did not put the card in upside down - didn't know until after that was what you're supposed to do, the card smelled of burnt plastic and the (Speaker?) was slightly melted not sure what it was it looked like a speaker ..probably the thing that makes the squealing sound when you forget to connect the two 6 pin connections..
Also now the monitor will not respond at all when I turn the computer on.. this could be something else because I have had this problem before when taking out the card.. it is put in properly but sometimes the monitor just would not respond to the card. But it is highly likely that it was because I put it in the oven though haha.
I would not tell anyone to not try this because I have read so many peoples responses to this trick on other forums/youtube videos so it probably does work, I guess I just got unlucky.
Anyway everything arrived for my new PC two days later all I need now is the SSD and windows 7 and I can get it up and running. I will probably go and buy a cheap card so I can still use this computer seeing as everything else still works and I want to use it as a media center.
Thanks for all your help guys!
