My computer is unable to boot or do anything. If I remeber right it is a AMD proccessor, PC266 motherboard ( I am using built in monitor connection). have 512 mb RAM, and a 200 gigabyte HDD. The computer will turn on and the hard drive starts to spin and even the CD drive will start to spin but nothing else happens. When reset button is pressed the monitor screen will refresh to another black screen just like before pressing the button. I have tried monitor on another computer and it works and I have even put in a new graphics card and tried to run it but still the same thing. Please help!!!
