64-bit - Blank screen on boot up, before login screen; slow startup

[TechBoi]

Bonjour mes amis.

I recently have started getting the infamous black screen of death at my computer's startup, very similar to this fellow user's problem. Basically, Blank screen on boot up, before login screen; slow startup. The black screen lasts at least two minutes on average, before the windows login screen comes up. Everything else runs fine!

I think it might be my antivirus, Bitdefender Total Security 2013, and I've posted on their forums about it, and I've gotten responses from other users saying:

The Black screen issue is known by BD Support till now they have not able resolved that issue.
hope BD 2014 resolves the issue.

And the booting time issue is been solved.

However, I uninstalled Bitdefender and the problem still persisted. I proceeded to uninstall every program i could remember installing before the problem started, so before the start of June. This was painful because I updated all my software, so everything was listed as installed recently.
My startup time after removing all these software is attached below; 156 seconds, compared to before with the speed ranging from 200-500 seconds, with the worst at 472 seconds.

Although this sped about my startup, I still got the annoying black screen issue. I am sure it is a software issue because the black screen is present, but lasts no longer than about 5 seconds when starting in Safe Mode with Networking, and is present even int he low graphics.

What should I do? My specs are filled out, and I am going to to a fresh install of Windows 7, so right now i ma backing uo my C drive. Any other suggestions? Should this work?

Thanks for the reply, but I did a fresh install of Windows 7 and it worked! The black screen is gone and my computer is super-fast! Look at this!:

Great stuff now try the Optimise tutorial you will find it even quicker especially points 1 (if you can afford one LOL!!) 4,5, 7, 9, 15,16, 19 (CCleaner is good if you haven't got it - free) 20, 30 and 34.

They are the ones I always set and you lose some of the "bling" but for example - me transparency really is not that important.

Enjoy

That issue could have been due to heavily fragmented files, if during that blacked screen if your HD LED was staying red, that is a highly likely the cause.

Wipe and drop of fresh 7 would certainly fix that, welcome back to smooth fresh 7 speed!

I WAS scratching my head with those "200-500" second restart times Keeping it clean and tight will keep you those numbers too.

Hiyya mate did you try the optimise stuff - am just curious to what the start up and run times are now

Many thanks! And I think I kept all my drives defragmented before, so that might not be it!

Trying hard to keep them low, but they keep increasing! D:

Sorry mate, I was busy installing the software I had back onto my new system. Now that I'm done, the boot time is about 2:17 minutes, even though I'm trying to keep it clean and tight. According to the data I've accumulated, the biggest time-suckers are "system," taking 32.2 seconds to boot up followed by "Windows Modules Installer (trustedinstaller.exe)" taking 23.8 seconds to start up.

I'm going to follow your other posts instructions now, and I will try to keep you updated! Thanks!

Here's my startup time before applying these tweaks (AKA right now, fully set up):
