crashing when switching drawing tabs

[jcole]

I am crashing at least once, maybe twice a day and it usually happens when I switch from one drawing tab to another. I had noticed previously that alt-tab tends to crash my machine so I am not using alt-tab as I used to to switch between drawings, but I am still crashing a few times a day. Any ideas? I have two other machines that were bought at the same time mine was, same specs, same graphics card and they are not crashing like I am...It seems to be on any drawing - not one in particular... ?

thanks

AutoCAD version?
Windows version?
Graphics cards?
specs?
What else do you have installed (software, hardware, plugged-in or unplugged etc.) or not isntalled that the other non-crashing machines do?

sorry -

Architecture 2015

windows 7

AMD FirePro 4900

the only think I have installed that others do not is Roxio but I haven't used it and its not open..

I disabled Aero Themes

No Rixio here. In plain AutoCAD 2015 (where you are posting), WIn7 64bit, generic video card, and I switch all day long either with CTRL+TAB (alt+tab is different) or by clicking on the FILE TAB button. No crashes due to that action. So that doesn't help you LOL

Are you all using the same video card drivers? do they have upgrades or downgrades? installed software can cause issues, whether you run it or not. Do you have a phone plugged in? sounds wierd but that be an issue sometimes. What else is different?

Okay - so over the past month I have been trying to pay more attention..It seems that the autosave is somehow affecting my crashes. If I am in the process of panning when autocad decides to autosave, there is a crash. I think my computer is crashing more than others because I have multiple files open, autosave set to 5 minutes, and so there are a lot of autosaves going on.. maybe?

Hello from France

Just a few ideas :

Q1) Please open your DWGs in RECOVER Mode and RESave them ...

Q2) Have you installed the SP 1 for ACAD Architecture 2015 ?

Q3) Have you installed the LATEST AMD driver for your FirePro 4900 ?

Q4) If you run with Graphic hardware Acceleration DISABLED, have you LESS problems ?

CTRL+TAB is switch between open dwgs and ALT+TAB is to switch between open sessions of programs. If you are running multiple sessions of ACAD you will experience a majo slow down and possibly crashes because there is not enough RAM or processing speed.
