when i play like farmtown on facebook or cityville, it just restarts randomly after i think about 30 mins. But when i play Frozen Throne i.e. DOTA for like 30 minutes also Blue Screen Of Death appears and i forgot what it says because theres so many writings in it. This just happen when i upgraded my RAM from 256mb to 1GB. My Processor is Pentium4 2.67GHz, RAM 1GB, Video card is GeForce4 MX 440 with AGP8X size 64MB. My OS is Windows XP. could it be the RAM or the video card. If its the RAM its gonna be wasted because i cannot refund anymore.
