When I first got the computer, it would not even turn on. It would get power (the lights on the front of the tower lit up) but gave nothing but a black screen and a beep code. I researched the beep code and found out for this computer it meant that there was an error in memory. So, I opened up the box and took out a stick of RAM to see what would happen. Without that stick of RAM, the computer booted up to the select your profile screen and when I clicked the profile it began to log on. It showed the desktop (without icons) for a few seconds then went back to the profile screen and said it was "logging off". I rebooted the machine and tried to log in in safe mode but, I got the same result. I also tried logging in as Administrator, but it was the same thing. I put my own Windows XP Pro CD in the CD-Rom to see if it would allow me to restore or repair Windows, but it didn't do anything different. It seemed to not even register that there was a CD in the drive.
I don't know what happened with this computer before it was in my possession. I have no idea if there was a virus or some malware. The most information I can get from my friend is a confused face and her throwing her hands up. So, any help is much appreciated!! Thanks in advance!!
