I was having Intel Desktop Board DP55KG with Microsoft windows 7 operating system involved on it. The Desktop Board DP55KGwas having very good feature of overclocking. Due to this we can increase the CPU speed for achieving better performance. The desktop board also has the feature of ATI Crossfire and NVIDIA SLI technology which gives amazing graphic performance. While starting the system it freezes. After restarting the system again it starts correctly. I need solution so that I can troubleshoot this problem.
