This is the same problem I'm having especial loading video drivers for my 64 bit machine an 64 Nvidia GTX 970 4 Gb this is so frustrating Nvidia has 64 bit drivers an 64 bit G-force Experience but it all keeps loading this lousy 32 bit ****! Whats the sense of having a 64 bit OS when every things being seen an loaded in 32 bit? And I think It is windows 10 because all windows apps are 32 bit so they set up the system to auto lode 32 bit everything! For compatibility with their **** 32 bit apps an third party 32 bit security risky BS apps, I for one have had nothing but problem after problem, an I'm about to smash this PC I've wasted ( 1,400 $) on into tiny little pieces, an send 1/2 of it to Microsoft an the other half to ASUS! an then go out an buy a real PC with Apple Installed or Linux even my Norton loaded in 32 bit, an audio drivers, video drivers, ETC, ETC, ETC I for one M just about done with this third party BS spyware ready threat, (called windows 10) allows anybody an their brothers (etc) in the back door of your PC by Default, (Pathetic) Is the word that come to mind when I here (Windows 10 is the best an most secure!) BS Its bean the worst threat ever I've encountered, an the most incompatible, An absolutely no help from Microsoft or their support team, all I get Is contact your manufacturer, or you sign the terms an Licence agreement, (In short your screwed) witch I've never sign anything their was no agreement on the side of the box it sold in! cause if their were? I would have looked at it a whole lot closer, an probably wouldn't have purchased this PC (nothing works like advertised on the box) altogether! an bought some thing Different,That was a little more secure an a little less demanding an or controlling my every key stroke, an apps that i want or don't want, good Luck to you you'll need it, were all in the same sinking Windows 10 ship, An I for one M close to bailing out, for security reasons. Rant: solved Big Bugs, I take back half of what I said, not going to say (what half)! Because my data maybe harvested, Key strokes monitored or recorded called key loggers, an some one I don't want with the data might just get it! an then know both half's, an we cant have that, So I'm standing on the fifth amendment.
