Windows Fast Startup and your bios fast boot will work together just fine. The BIOS fast boot expedites the POSTing while fast startup keeps your systems files in RAM so they don't have to load from the hard drive when booting, so it is unlikely either are causing your freeze issues.
nono, the freezing and the the fast startup are 2 seperate issues.
For the startup issue, i keep the bios setting disable for quick boot, but I ran into that power option that defaults on fast startup. Although now that you mention it, if the fast startup default option keeps my system files in the RAM, but I have it set in bios not to warm boot ram, and to enable memory clear, that sounds like a confliction unless one overrides the other?
The freezing issue was when my computer would either hibernate or sleep, don't remmeber which, and sometimes if certain programs were running at the time of being put to sleep, wwhen I tried waking it back up, it never would, the screen would just stay black and the power light wouldn't click over to blue. So I usually never use hibernate or sleep, altho i have a feeling it was hibernate that did it. Plus I don't like the huge hiberfil.sys file sizes.
