I built my computer around two to three moths ago and the computer started to have irregular crashes seemingly randomly. The crashes mainly happen when playing games but it has even crashed while burning a disk. Sometimes it will work fine and games can work for over 3 hours until i stop but it can crash after 5 minutes sometimes. The crashes lead to my hdd breaking so i assumed it was the hdd. However after i received my new one under warranty the same crashes have started to occur. I dont know how to find out whats causing the problem so i am unable to fix it.
