Windows 10: Windows 10 no signal to display or slow boot

After installing windows 10, most of the time when I boot after the windows logo with circles below it the signal to display stops, if I press reset then the computer boots but the startup is very slow. With windows 8 from pressing the power button I would get to desktop in 8 secs, here it takes at least 30 secs or more. I would like to know the if problem is with windows 10 or Nvidia drivers.
P.s: I have Nvidia's 650 Ti boost card.

Slow running anniversary win 10 up date

Hi

already had tried troubleshooting option

tried a clean boot as suggested BUT

same problem remains, task manager still runs slow and when using other options that open another window it appears as an outline for some time before showing the contents. as f slow to rest display checked all display settings and also checked all drivers
up todate, went back to normal start up seems to boot quicker BUT still slow in other ops

All settings, programs and hardware are the same as before I loaded the anniversary update would go back if I could find a way to do it

this slowness is driving me mad as seems linked to mainly Win 10 operations task manager, system config etc.

 

windows won't start in first attempt

When I start my window 10 on my Dell desktop, lately the signal on the monitor is not there or the window 10 does not boot up. After leaving it on for while without any signal, turning it off and on again, then it boots up. What could be the issue>

 

Hi, if you have a Windows 10 version 10586 (the November upgrade and later), please be aware a number of users are reporting slow boot times, but not with the preceding build, 10240. There are other threads on this problem here.

This seems to be a difficult problem, and the the conclusion I've seen is to wait for a fix.

What can you do? Beyond that you can:
- try a clean boot. What effect (if any) do you note?
- use Autoruns (freeware) to additionally disable anything you don't want running
- If you upgraded rather than doing a clean install, compare the boot time with a clean install, and a clean install of the 10240 build - to see if it's a problem with the build.
(Note you can use disk imaging software to save (and restore) your existing configuration, or just swap the HDD)
- Use the Event Viewer to inspect events with Event ID 100

There are tools provided by MS to analyse boot performance, but these are technically advanced.

Others may hopefully have more ideas.

Please have a look at other threads - search for 'slow boot'.
