I thought I knew what I was doing, and now I am in trouble. I just built a computer, BIOSTAR TFORCE TA790GX 128M AM2+/AM2 AMD 790GX HDMI ATX AMD Motherboard; AMD Sempron 64 3800+ Manila 2.2GHz Socket AM2 Single-Core Processor Model SDA3800CNBOX; Western Digital Caviar SE WD800AAJS 80GB 7200 RPM SATA 3.0Gb/s Hard Drive; G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ; some generic cd-rw, and a 350w power supply. When I try installing windows xp home, the system freezes at step where the windows setup says "Setup is starting Windows." What can I do to fix this?
