I am having problems with dwm.exe and explorer.exe starting up correctly sometimes on windows7. It doesn't happen every day. Sometimes it might be a month in between those not starting up. Originally, it was just dwm.exe, but now, it's always both or neither. I can start up explorer.exe via task manager, but I know something has to be causing the issue, so I'd like to get it fixed before it turns into a major problem. I had not installed any new programs when the error first happened. I use ETrust Security Suite and Spybot Search and Destroy to try to keep my PC clean. I also have gotten into the habit of letting firefox remember the last few tabs I had open from the previous day, so if that could be causing the issue with dwm, let me know and I'll stop doing that. I have a homebuilt PC with a valid copy of win7 that I bought, so I can re-install it if needed, but I really don't want to do that and lose all my programs and files. I'm trying to back them all up now though, but it won't happen in a day and it's a hassle to put them all back on pc.
Does anyone know what might be causing this problem and how to fix it (or things to try to see if there is a problem)? Any programs that conflict with these that might be causing this? Thanks!
