So I've been using Windows 10 on my laptop which shipped with windows8 pro 64 bit. It's a Lenovo ThinkPad E530 with 8GB RAM. I used Microsoft Edge browser with like 10 tabs open, one was a YouTube livestream. Upon opening a new tab the browser stopped responding same with the taskbar and i couldn't open the task manager or anything else. It's not the first time this happened, so I forced the computer to power off and tried to start it again, but now i don't even see the Lenovo splash anymore, just a black screen without any bios sounds.
How can I fix this?
Edit: I can't even boot from CD The Ram cards were removed and a sound code was given. However the RAM were inserted one by one in every slot and still no success with booting any further Thanks in advance.
