I have a machine that started to show BSOD immediately on Windows login. I was using Windows 7 ultimate. The BSOD showed differing information on the startup so haven't included any information here. I have replaced moethrboad, CPU, memory, PSU, CPU cooler and ensured that the machine is not overheating. I have checked the system with different hard drives and disconnected the DVD drive. I have tested with a different graphics card. I have resorted to trying to reinstall Windows . The computer freezes at random points during the install or allows installation and then freezes on Windows login. I am at a loss as the only thing I have not replaced is the case. I have run tests on the memory, graphics card, etc but it shows no issues on any component. Any ideas?
