Sorry to hear you are having problems. I have had this same issue before with this particular model. The following solution works 90% of the time.Perform a hard reset

Blink codes are often displayed after a
user adds memory to the computer but does not seat the module properly.
The LEDs may also blink error codes if a hardware component is loose
because the computer was dropped or jarred. Some HP Notebook PCs come
with one stick of memory but have two memory slots. The problem could
be that the stick of memory or one of the memory slots has a bad
connection. The memory module
compartment on most notebooks is located on the bottom of the case. The
exact position varies by model. However, on some models, the memory
compartment is under the keyboard. See your User Guide for the exact
location of memory modules on your notebook.
Use the following steps to remove and
reseat the memory modules:
Step 1 -
Remove the electrical power
To remove all power from the computer and
prevent accidental damage to the electronic components, do the
following:
1 - Pull the retention clips away from sides
of the memory module
2 - Gently pull the module out of the memory
module slot
After reseating the memory module, replace the cover over the memory
compartment before restarting the computer
Hope this helps FiYa! If you find this solution helpful, please take a moment to leave us some feedback.
Thank You!

If it does not even post or show the DELL Logo then this may already be a hardware failure. The best thing to do is to contact Dell Tech Support. Specially if you still have warranty. It could already be a couple of things ranging from the memory to the motherboard itself.

A quick look on the Internet and the DELL support side indicates the flashing caps lock light is the result of a SDRAM memory fault. It flashes 10 times, after which all led lights above the keyboard go off.
have you installed new memory lately? Maybe it cam loose. If not swapping out the memory may solve your problem.

Caps lock flashing indicates faulty memory - it's a POST (Power On Self Test) before BIOS executes. When memory is removed it should indicate "no memory". Carefully re-insert the RAM memory module, check the tiny contacts inside the connector on dust. Then try again.
If there are 2 memory banks (1 one the back, the other under keyboard) remove one RAM memory module.
If capslock keeps on flashing test it with another RAM module.
