I have an <a href="http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01469325&lc=en&dlc=en&cc=us&lang=en&product=3740333">hp pavillion media center m8530f desktop pc</a> with a <a href="http://www.nvidia.com/object/product_geforce_gtx_260_us.html">gtx 260 graphics card</a>, and an <a href="http://www.ocztechnology.com/products/power_management/ocz_700w_stealthxstream_power_supply">ocz700sxs power supply</a>. I also added an extra gigabyte of RAM. It was running Windows Vista Home Premium 64 bit. Anyways there was a problem with my motherboard so i got a new one, an <a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16813131608">ASUS M4A78L-M</a>. It came with an <a href="http://en.wikipedia.org/wiki/Athlon_II">AMD Athlon II processor triple core</a>. My problem is that I don't know what to do in regards to having an OS. I cant upgrade without doing a clean install, but i cant backup my data because i dont have the means to do so. Please let me know what to do, and thanks in advance.
