Geekcon Hackathon

Geekcon challenge Hackathon doesn't work but occasionally video gaming challenge does.  I have repaired game twice but does stop it freezing up my computer. It causes blank screen but unsure of cause but both problems happen at same time. I just installed new expansion pack Adventure Awaits and been doing the newest freebie challenge. It was worst due to being invited to the Geekcon and  not being able to complete request or the blank out and can't save progress so basically lose all prior progress. I won't lie I forget to save regularly when playing same family. It's not my laptop over heating or background programming since any running are the same that have always done. My security protocols are run regularly so don't believe it's the laptop. I don't know what to do game related other than repair. I even deleted any games that were played during that time it started. So far the new start has been doing fine for not blanking out but today the Hackathon didn't work but the computer is show yellow and I could listen to the launch and any other normal computer use. I didn't try the video game systems. Thank you for any help.
