Hi there, about 1 month ago my old CPU died and I bought a new one (a new Motherboard aswell). But unfortunately after this "upgrade" I got dozens of bluescreens. My Hardware Spec: CPU: Intel I7 4770K Motherboard: Gigabyte GA-Z87-MX-D3H Ram: 2x 2GB DDR3 1333Mhz + 2x 4GB DDR3 1333Mhz GPU: Sapphire Radeon HD 7950 PSU: Be quiet! Straight power 600W OS: Windows 8.1 64-Bit I gone through the checklist for troubleshooting and according to my event log and eventid.net is the error caused by "Microsoft-Windows-DistributedCOM". Description by eventid.net: In fact I don't know what this means. Is this error caused by a hardware or software problem? I still got warranty on my CPU and motherboard RAM is tested and error free. I hope you can help me with this problem.
