I have had my system for about a 8 mo now. When I have had it on for a while and goto reboot It halts and does not comeback up. I thought it was heat so I took the sid off my case and it helped. I have also noticed that when I play video games it gets jump. Keep in mind that this all started within the last few weeks. Does anyone know what can couse this? Should I buy a new MB? Thanks in advance.
