It beeps a series of beeps and then does nothing. Probable cause: You have some sort of hardware problem. Possible solution: Those beeps are actually telling you something. They are called POST error codes. Here is a list of what some of the POST error codes commonly mean and how to fix them: One beep, repeating - DRAM refresh failure. Try reseating or replacing your RAM. Three beeps, repeating - Base 64-Kbyte RAM failure. Try reseating or replacing your RAM. Four beeps, repeating - System timer failure. Try reseating or replacing your battery or motherboard. Five beeps, repeating - Processor failure. Try reseating or replacing your CPU. Six beeps, repeating - Keyboard controller error. Try reseating or replacing your keyboard. Seven beeps, repeating - Virtual mode exception error. Try reseating or replacing your RAM. Nine beeps, repeating - BIOS checksum failure. Try reseating or replacing your BIOS and/or battery (if you don't have a soldering iron, or don't want to spend the time, try to replacing your motherboard) One long beep followed by three short beeps - Memory test failure. Try reseating or replacing your RAM. One long beep followed by eight short beeps - Display test failure. Try reseating or replacing your video card. In all cases above where that does not fix the problem, you may need to replace your motherboard. There is no standard for POST error codes, although the above list is generally correct, so you MAY not have the problem listed. A few things to try in anycase are: Remove all of your cards and reseat them. Remove your RAM and reseat it. Remove your cables (from the motherboard and devices) and replug them in Replace your motherboard. Replace your CPU.
