Hello!

So, my alienware crashed yesterday saying it had a memory crash and needed to restart.
The problem is it couldn't boot.
A the BIOS my Hdd is being recognised, WDC WD10JPVX-75JC3TO 1000GB
I already tried booting on Legacy and UEFI, non worked.
I also unplugged all cables connected to my laptop.

Please help

PS: don't know if this is relevant info but i downloaded windows 10 almost 2 months ago, my laptop started doing weird things after i downloaded it.
