Windows 7 fails to boot, no windows start up screen
I have searched through a lot of threads here and am starting to lean towards a hardware issue. I will try my best to give a run down of what I have, what i seeing, what i've done and anything else that may help.
Computer is about 8 months old.
Toshiba Satellite L755D-S5106
A few days ago I turned it on and after the bios screen I received a bootmgr error. I tried a start up repair from my windows 7 dvd, along with some various online tips. Occasionally the computer would start up, but not always. When it doesn't start up, it goes through the bios screen to a black screen and stops. It will sit at this screen for a few minutes before it reboots and tries again with the same end result.
I eventually decided that I would start with a clean slate. I formatted the hard drive, removed all partitions and did a clean install of windows 7. After installing the drivers the computer runs, but is (best way to describe) laggy. Everything taking longer than it should to do anything. After windows completes all its updates it again fails to boot. I have run start up recovery and it tells me i can not find any issues.
I ran memtestx64 and it found zero issues. I downloaded the HD test software found at this link
Software Utilities
But the issue is I can't access the advanced boot settings via f8, as nothing happens other than my computer beeping at me and sitting there with a black screen.
I am open to ideas, options and things I should try.
