My HP computer flashes red light and beeps 5 times stops then 5 more on and on ,this at start up will not start . I have unplugged hard drive, memory stick replaced CMOS battery,still not starting. I have a new hard drive and CD Drive, but they are not installed for the current problem. Any ideas . Computer is HP elite Desk.

Hi,
What is the full model number of the desktop?
Have you re inserted the RAM module (memory stick), you didn't say?
Having no RAM module inserted will give a 5 power light blink, 5 beep error code
If you have re-inserted the module and are still getting the error light/beeps, replace the module with a compatible replacement module and check if this resolves the problem.
If it still fails it may be a memory controller issue on the motherboard

If it's a memory controller issue, how can it be fixed?
@Lala Hetman
As a DIY repair you will have to replace the motherboard.
Alternatively you will need to find the motherboard schematics to find out why the memory controller isn't working
replace processor....

The possible reason as an overloaded power supply. Disconnect all external devices to see if any of those items are causing the problem, (such as a hard, diskette, or optical drives, and expansion cards). Power on the system. If the system enters the POST, then power off and replace one device at a time and repeat this procedure until failure occurs. Replace the device that is causing the failure. Continue adding devices one at a time to ensure all devices are functioning properly.

Thank you so much for this pointer. My HP suddenly packed in this afternoon. One moment it's working, the next the screen is black. Nothing worked. None of the TTY's worked. So I rebooted. Red light and beeping. I reseated RAM, took one by one out, eventually took out all, and still beeping. I read somewhere that another cause is a bad CPU. I took that out, put another compatible one in, still beeping. Read this post, took out the GPU, and it works!! I have no idea why the GPU suddenly started to drain hundreds of watts for no reason, but this was the fix. Thank you!!
