I havn't tried Oven baking, can you elaborate please AHarvey?
Oven baking consists of stripping it down to the motherboard only, wrapping it in cloth, silver foil and then putting it in the oven.
I've tried it a few times now and it works every time.
Try local charity shops, buy old oven gloves and towels that can be cut up. You then need to cover the motherboard in them. You need to cover everything but the top and the bottom of the mobo where the cpu and gfx chips are. once you have a nice thick covering, around an inch I find, you then need to cover the entire thing with silver foil, again, leaving the cpu and gfx chip open to the air top and bottom. You need to make sure the silver foil goes down in the gap and is tucked under the towels.
You can use electrical tape or masking tape to hold it all in place, however it's supposed to melt slightly or singe and make a horrid smell. Some Americans use aluminium tape as it is resistant to the heat but I can't find it here. I use normal selotape to hold the towels in place as its protected by the foil.
Then, put it in a pre heated oven on top of a baking tray as it allows the air to get underneath. I use gas mark 9 for 9-10 minutes. Once it's been in for its time, remove and leave on the side to cool down to room temp, I usually leave it for a minimum of 4 hours to be safe
There are youtube vids on it that may help but I find they lack great detail, but it will allow you to see what it should look like. I'd link to some tutorials, but last time I did they were removed!
Once cooled, xclamp fix, increase cooling and rebuild it
I've said I would write a guide for a website when I next do one, hopefully this weekend
