When I power the system on, I see the power LED light and hear the fans spin, but nothing else ever happens. The system beeps when I turn it on, but there is nothing on the screen. I see a STOP or STOP ERROR in Windows NT/2000/XP. I see Fatal Exception errors in Windows 95/98/Me. The system won't shut down in Windows. The power button won't turn off the system. The modem doesn't work. The keyboard doesn't work. I can't hear any sound from the speakers. The monitor appears completely garbled or unreadable. The image on the display is distorted (bent), shaking, or wavering. I purchased an upgraded AGP video card, and it won't fit in the slot. I installed an upgraded processor, but it won't work. The system runs fine for a few minutes but then freezes or locks up. I am experiencing intermittent problems with the hard drive(s). The system won't boot up; it says Missing operating system on the screen. The system is experiencing intermittent memory errors. The system locks up frequently and sometimes reboots on its own. I installed a 60GB drive in my system, but it is recognizing only 8.4GB. My CD-ROM/DVD drive doesn't work. My USB port or device doesn't work. I installed an additional memory module, but the system doesn't recognize it. I installed a new drive, but it doesn't work and the drive LED remains lit. While I was updating my BIOS, the system froze and now the system is dead! I installed a new motherboard in an older Dell system, and nothing works. I installed a PCI video card in an older system with PCI slots, and it doesn't work.
