Can any one help me with my problem?
After:When I turn on my computer it has a black screen and it beeps.This has happened before but I have fixed that problem.... When I changed the graphic card from AT Radeon to Nvidia Geforce 9800GT.We went back to the shop and they told us we had to add a cable to the graphic card to the main power of the computer.
Before this:We called a person who repaired computers because our computer would not start up propely.He told us it was a virus and he deleted all viruses.After that we told him that one of our CD-ROM Driver would not read CD's.So he disconnected it to save power until we get a new one.We also used a vacum to remove the dust in the computer.We also removed the fan and cleaned the dust under it.When we connect the plugs to the computer and turn it on.It turns on firstly and shows the intel pentium 4 picture like usuall but it freezes so we turn it off and on but now it makes beeps and has a black screen.
