Windows 10 VERY SLUGGISH coming out of sleep mode

Hi all.

Recently I have noticed that my computer is EXTREMELY SLUGGISH after I wake it up out of sleep mode. It runs very very slowly. Rebooting is the only thing that fixes the sluggishness but then it happens again once my computer is put to sleep and then wakes up.

My computer is an Alienware Area 51 R2. I upgraded to windows 10 about a month ago without any problems. I have the Hibernate feature turned off as the files required to preserve my computer state during hibernation take up far too much space on my tiny 120 GB SSD that windows is installed on (all my games and other stuff are installed to the 1.5 TB standard platter-based hard drive) Sleep function remains enabled though.

I have a pair of NVIDIA Geforce GTX 980 graphics cards and am using the latest graphics drivers with them (358.50 according to the latest update i got).

Defragmenting (and in the case of SSD, trimming it) have not helped.

Anyone able to help?

Clarification Request
Waking from Windows 10 sleep very slow with GTX 980

I think the same thing.... I also notice a significant delay when the GTX980 resizes the monitor so I'm thinking it's the display driver reconfiguring memory or similar. Why it has to forget the display sizes and frame buffers, should this be the case, it remains to be seen and I can't think of what to do to pre-empt it except disabling sleep which corporate policies prohibit Sad

There's your exit.

Since it's a company PC you kick it back to them to fix it.

Checked For An Updated Chipset/Motherboard Driver?

These drivers, or possibly a BIOS update, could be needed because of the new operating system. Visit the computer manufacturer, or the motherboard manufacturer's website to check for Windows 10 updated drivers.

Hope this helps.

Already checked for updates to drivers/BIOS

None are available for my Alienware currently.

So you did a little research like this.

Already provided this information

I already mentioned in the OP that I have hibernation turned off because the page file that stores the system state for hibernation takes up too much space on the C: drive (the SSD) where windows is installed on. I know how to turn it off, i already did that. But it continues to be slow when waking up out of sleep mode, sometimes freezing bad enough that the only fix is to hard reboot.

Since there are no drivers for 10

And the ones for 8 don't cure it, I'll share the office upgraded my work laptop with a 512GB SSD and set it to hibernate. Works great. They did a little math and it might drop the lifespan by a few months so that's why we left it on hibernate.

In your case you may want to go back to the prior Windows until Dell sorts out drivers or someone finds a working solution.
