I downoad it but it has Windows XP and it is running dog slow. I don't want to start the upgrade and then it stop or freeze up on me. I don't know why it dog slow cause I upgraded the memory to 3gb ddr2 5300. I got it free and I just wanted to upgrade the OS to Windows 7. My main OS is a live version of Linux (Porteus) and it run supper Fast. When I do the bios upgrade I want it to work. Right now it has AMD Sempron 64 3400+ processor - 1.8GHz (800MHz front side bus 256kb L2 cache, socket (940 pin) AM2) and I think it can be upgrade to without a bios change to AMD Athlon 64 X2 Dual-Core 5000+ processor 2.60GHz (1GHz front side bus 2MB L2 cache (Dual Core technology, 1MB per core) socket (940 pin) AM2) but I'm not sure of which 5000+. That why.
