Hi there, I'm a newcomer to this forum, and I should let everyone know my computer knowledge probably isnt as good as most members here, but I seek urgent help, and I hope I can find it here. As the title suggests, I encountered 4 completely different BSOD's today, while the 5th most recent one was 10 days ago. I have tried seeking help on another forum but sadly nobody seems to be answering my problems. I've also looked at other forums and websites for solutions but a lot of the terms and jargon get me all confused, especially when explaining what's causing the Blue Screens. However, with the help of BlueScreenView, I can roughly figure out two of the BSOD's (do correct me if I'm wrong): ntfs_file_system 0x00000024 is most probably caused by a failing hard drive. This means I should go get a new one then? memory_management 0x0000001a is caused by faulty memory. Is this where the Memtest program thing comes in use? I hope the forumers here can have a look at my Blue Screens attached below and provide me easy-to-understand step-by-step solutions to resolve them. Having four separate BSOD's in one day is not anything to take lightly. Oh, and if it helps: Acer Aspire M1600 Windows Vista Home Basic Service Pack 2 32-bit X-86 3GB of RAM, Intel Core 2 Duo @ 1.8Ghz 2 weeks ago I cleaned up all the dust the inside of the computer. I took out the main CPU fan and graphics card (like I always do when cleaning), cleaned it and put it back into place; securely, as I always do. A week later, I started having CMOS Cheksum errors, but soon got it fixed by replacing a new CMOS battery. Now, these blue screens start appearing.
