Click on the search icon, type power. Click Edit power plan and then Advanced power settings. Expand sleep, then Allow wake timers and set it to disable. Try to put it to sleep again to see if it works. Of course you must have all drivers installed, if anything is missing or has a problem it may prevent the computer from entering sleep mode. Search for device and click to open Device Manager. There should not be any unknown device or anything with a yellow mark etc.

Unfortunately this hasn't worked is there anything else I can do ?

Try downloading and installing the chipset drivers from manufacturer (not Windows Update).

My new Hp desktop came with Win 10 installed and sleep worked fine. But after the big update came sleep quit working: would not sleep when it was supposed to and if you forced it to sleep it would wake up fairly soon (sometimes in less than a minute).
I have made the following changes and now sleep seems pretty reliable:

1. Did what Spapakons suggested last week but that didn't help: Disable "Allow wake timers" in Sleep in Advanced Power Settings.

2. Using Device Manager, accessed Power Management tabs for LAN (ethernet) controller and WiFi Controller. Disabled the option to allow the device to wake the computer. I also disabled the option to allow the system to turn off power to the controllers to save power (since this is a desktop PC) -- I suspect that this was not necessary.

Sleep seems fine now.

This worked for me. Also if you have the Realtek HD audio driver it may be that it was a problem for me in win 7 and win 8 I use the MS HD audio driver works well with 5.1 surround sys.
