What does it mean when my desktop computer beeps long beeps and wont turn on?

These "bunch of writings" hold the answer. If you want more help please edit your question with them so i or others can help you better. For the time beings I think its is a RAM or a keyboard issue. Disconnect and reconnect the keyboard or another one that works. or the RAM has to be taken out, the slot cleaned, and reset again one by one. Beeps are error codes that differ from one bios to another. Here is a long list of most known bios and there error codes, you might want to look at it: Computer POST / beep codes Quick links POST ABCs The steps of a POST POST troubleshooting AMI BIOS beep codes Award BIOS beep codes IBM BIOS beep codes Macintosh startup tones Phoenix BIOS beep codes Motherboard help POST ABCs The computer POST (Power On Self Test) tests the computer, insuring that it meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process. If the computer passes the POST the computer will have a single beep (with some computer BIOS manufacturers it may beep twice) as the computer starts and the computer will continue to start normally. However, if the computer fails the POST, the computer will either not beep at all or will generate a beep code, which tells the user the source of the problem. The steps of a POST Each time the computer boots up the computer must past the POST. Below is the common steps a POST performs each time your computer starts. 1. Test the power supply to ensure that it is turned on and that it releases its reset signal. 2. CPU must exit the reset status mode and thereafter be able to execute instructions. 3. BIOS checksum must be valid, meaning that it must be readable. 4. CMOS checksum must be valid, meaning that it must be readable. 5. CPU must be able to read all forms of memory such as the memory controller, memory bus, and memory module. 6. The first 64KB of memory must be operational and have the capability to be read and written to and from, and capable of containing the POST code. 7. I/O bus / controller must be accessible. 8. I/O bus must be able to write / read from the video subsystem and be able to read all video RAM. If the computer does not pass any of the above tests, your computer will receive an irregular POST. An irregular POST is a beep code that is different from the standard one or two beeps. This could be either no beeps at all or a combination of different beeps indicating what is causing the computer not to past the POST. If you're receiving an irregular POST document CH000607 contains all the steps a user can do to resolve the issue or help determine what hardware has failed in the computer so it can be replaced. If you're getting a beep code the remainder of this page contains a listing of each of the major manufacturers beep codes and what they each mean.

I need to know what type of computer to tell you (specifically your Bios version that is on your motherboard to tell you). It is a Bios Beep code.

A crucial peice of hardware is missing or damaged....open it and reseat(take out/put back in) all the components then try again....in most cases something came loose
