Question about HP Compaq dc7100 Ultra-slim PC Desktop
When trying to power on the red led light at the front of the unit is constantly flashing and will not power on, any ideas?
When I press the button to start up it goes for a couple of seconds then powers off and the red light flashes at the front?
Each flash of the red light comes with a beep from the speaker. It repeats 5 times this sequence (11 seconds each one):
- 9 flashes and beeps (1 per second)
- All flashes and beeps stop for 2 seconds
Then, after 55 seconds (5 times this sequence), the red light flashes 1 per second but there are no more beeps.
I tried looking for the beepcodes in bioscentral but I haven't found anything.
Thanks for all,
Pls try to use another compatible memory stick.
then confirm the status of your micro processor

RAM is installed in pairs in mine, but be aware the board has 2x2 slots. In mine each pair is 1 black and 1 blue slot. Mine has to have matching RAM in each black slot first. And, yes, it did work loose once and need re-seating. Try that in yours.

Tips for a great answer:
Jul 01, 2012 | Dell Precision Workstation 470 (204816690)...
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.
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.
