I've been having a problem with my laptop for a while now. It takes multiple attempts to boot up.(It will have no display, the keyboard lights won't turn on, and the hard drive light won't show.) It sounds like the fans are running and I think the disc drive also runs and I can open the disc drive.
I recently did a clean install of windows 7 to see if that would help. I formatted my hard drives thinking it could of been malware. After the install I updated to windows 10. Now sometimes when it starts it will freeze after loading windows, sometimes before showing the desktop.
I've tried to start it without the hard drives, but it doesn't boot to bios. Right now I'm on it and it's working fine, but usually after I shut it down I have the issue. I read somewhere that it could have a faulty ram slot. I was wondering if anyone had any suggestions.
