The power supply can be replaced, make sure the wattage is equal or greater than the one you have taken out.
Here's how to replace the parts. Open with Adobe or the like and Print. I'd recommend you get someone to do this if you do not know how to. Anything done wrong can mean a unusable computer.
As for the RAM, you can easily replace it with two 1Gb DDR SDRAM. 2Gb's is the maximum.
Make sure it's NOT DDR 2 or DDR 3.
Also, make sure the chips are the same size. If you install it with a 256Mb and a 1Gb, then it could effect performance. In some cases, the newer computers run fine.
You will not need to reinstall windows for replacing the parts.

Ascaso, Innova, Dream Heater not working

If you are confident that your heating element is dead and are filling adventurous enough to replace it- you can get one at:

I saved myself shipping and repair costs by having it replaced by a friend. He took pictures and marked wires & connectors before removing the broken heater.
Yeah,, this looks to be systematic failure with this machine. Very disappointing- for this kind of money, one would expect the machine to work a bit longer after warranty expires.
