Yes, this is a good idea ! If you maybe were using GUI v. 7.0 oder lower, just try to download the 7.1 Version. I've heard rumors about crashes and bugs in this Version.
Nvm, I am using a console miner like CCminer, CPUminer_opt to connect to minergate pool.
Ps: I can give you tips to switch to a console miner and get it running.
Would be nice If you could register over my ref link above, so the time I will spend into my projects, will be regarded ! Thanks in advance :-)
