My BMW back light and clock lights dont work tried to replace fuse keeps blowing on a 325 TD

First of all I noticed my back light went of on my car, I lifted my boot to check if my bulb has blown, it wasn't so after I took the bulb out and put it back in I then sat in my car and checked to see if the lights went back on and noticed that also the dash board lights had also gone off. I then got out my car and check the front and lifted up the front bonnet and looked in the fuse box which is on the right hand side of the car, I replaced the 10 amp fuse which was blown at where I thought it had blown. And it worked at first for a about 24hours, and fuse went again and it blows every time I put a new one in to replace it, as a result to this fuse keep blowing I am having trouble getting my car started and also when getting my car started I am driving alone the road and my cut just seem's like its demobilised it's self like it has completely died on me, I may add when I first brought my car 2 weeks ago the two front electric windows do not work and I discounted them today on the switches to see if that was the problem but it has had no effect on the situation please help me I am have ran out of idea's of what to do?
