Hello everyone. I recently built my sister a budget computer to take to school with. This was my first build. The specs are as follows: AMD Sempron 2400+ Thoroughbred 333MHz FSB Socket A Processor Model SDA2400BOX - Retail ASUS A7N8X-X Socket A (Socket 462) NVIDIA nForce2 400 ATX AMD Motherboard - Retail Kingston ValueRAM 256MB 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered System Memory Model KVR400X64C3A/256 - Retail Western Digital Caviar SE WD800JB 80GB 7200 RPM IDE Ultra ATA100 Hard Drive - OEM SAMSUNG Black IDE DVD Burner Model TS-H552U/BEBN BLK - OEM JUST PC JPC727P4 Black Steel ATX Mid Tower Computer Case 450W Power Supply - Retail I flashed the BIOS so it could recognize the Sempron chip. After the flash, I went on to install windows XP Professional. It set up the files, formatted the hard drive, rebooted and continued. WHen a screen popped up asking me to select my langage I couldn't press enter on my keyboard. It seems to have crashed during the installation. nothing I pressed worked. so I rebooted, and then it said "keyboard cannot be found" and stayed on that screen. so I reset again, and this time nothing came up. The monitor stayed black, like it wasn't getting any juice. It should be stated before the keyboard was working fine, and the picture was comming up fine also. now the monitor acts like its not even connected to a computer. I am thinking the motherboard might be the problem. any ideas let me know please. I'm getting desperate. I will answer every and all questions. Since I just ordered it, I am sure newegg will help me out if needed.
