Visualitation-textures

Hello
Could anyone help me, please
I´m wondering.
I have a texture i created (an image i made in PC) and it turns out into grey when I activate in view the different models i have in that file. The bottom line is that in sketchup i have some 3d models i created. So when I activate them in view (´cause i separeted them in lawyers) all of them, the image becomes grey, and when i only left in view some of them (i mean, i hide most of them), the image becomes normal and i don´t have any problems. The PC has 32 gb of ram, i mean, u can see its great ut not that great, anyway, is that normal or my skp is in bad conditions. Yeah, this could be sth fool but i need to ask. Thanks.

Can you show us some screen shots or share you model?
