black screen during bootup

Leechap · 23 Oct 2015

I upgraded the day the day Win 10 came out as I am a self confessed computer nerd for the past 2 decades. My system is a laptop from 2012 but uses an i7 processor with good specs (HP Envy 15 3040) with 16 gigs ram. Ran win7 fast as you would like it to however, my system has the same black screen issue that you face since day 1.

I have tried everything and still no solution. Everything is updated with new drivers and tweaked. Hell, I have been running it since day 1 and now we are months later. NOTHING will get rid of that sluggish boot so it is clearly some piece of hardware that causes it in my case. Since this is a laptop I can't swap out much other than the HD but I have just come to accept that. I do NOT expect this issue to change with the update Nov 2 (although I wish it would)...

New systems will obviously be built with hardware that is fully compatible with Win 10 and will therefore, not suffer from this problem. Other than than that my system runs faster than Win 7 once it finally boots up fully. I run video editing software and Photoshop with are all pretty resource intensive and often at the same time with many other programs running as well and not even a slight system slow down so over all I am very impressed with Win 10.

The 3rd hard drive I am using is a Western Digital 1 Tb 7200 rpm SATA III drive. Sometimes when opening it with Windows Explorer is would pause for a few secs then open. Other times it opens quick. I have my main drive with a 320 gigs and another 2nd 320 gig drive. Both 320 gigs drive open quickly.
Maybe the 1TB drive is bad. I replaced it with another 1 TB drive. It does the same thing and it's on a different data drive channel.
So I'm leading toward maybe it's the Microsoft hard drive driver. It's definitely something in Windows 10 causing the occasional pause. I'm going to wait for the next big Win 10 update in November.

There is a big update coming out November with plenty of fixes. One thing you might be able to do is see if western digital has any firmware updates for your HDD. Besides this, the BIOS actually has a hand in some of that stuff, so you might see if you're able to update that.
Defragment, and hope it works better!

I was monitoring with Procmon.exe and noticed this \USB Drivers\25_escape\conn\ss_conn_service.exe. Samsung Smart Switch service used to back up my Samsung S6. It was installed on the drive I'm having problems with. I disabled the service SAMSUNG Mobile Connectivity Service. So far the 1 tb drive is opening quickly.

I'll write back as I monitor the drive.

Having Samsung Smart Switch service disabled did the trick. Yaaahhooooo.
I'm marking this solved for me.
