Computer shut down and red light flashing five times then three second pause and repeats


According to the troubleshooting guide for this model, the red light flashing five times indicates a problem in the RAM (memory), before the video subsystem is ready. You may just need to open the case and make sure the memory sticks are fully locked in their slots. If you just added new memory, it might not match the required specs.

Blank screen and the power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause Pre-video memory error.

Solution
1.
Reseat DIMMs. Power on the system.

2. Replace DIMMs one at a time to isolate the faulty module.

3. Replace third-party memory with HP memory.
4. Replace the system board.

Booting up


one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.

Going to Sleep Displayed


I turned on my computer and the monitor displayed this message on the screen "going to sleep no input received". I checked the power cord and unplugged it, nothing. No lights are flashing or beeping sounds. The CPU is working just fine, anyone have any idea what to do
