depending on your statement, I think that my PC spesification is well enough, but idk why unity still take a long time to respond even not responding. is there any crash problem in my application? what should I do? must I re-install my windows 7? thanks.
the problem should be for your motherboard or CPU ... anyway if these two doesn't make any other programs not responding or crashing during running other programs this may be problem of two facts :
1- your project is growing and it takes long time to load... if this is true , then when it is loading unity 3d you should wait for a little time it should get up... and be sure that no other programs are opened and you don't do anything else
2- you windows is getting virus or old ... i guess that this one is more likely to be true... it's problem of your motherboard or CPU... you can A:upgrade your system ... or if you want to choose the easy way B:reinstall you windows... it may help you a lot...
3- the other way to overcome this problem is to optimize your project... change the size of your texture and make your program easier to load up...
and if you have crashes in every program then i again suggest you to reinstall your windows... hope that will solve ur problem... thnx... Mobin Shakeri
