A BSOD is almost always caused by either faulty hardware or faulty drivers. This is certainly not 100% of the time, but it is the vast majority. If you posted more information on
what kind of BSOD you are getting (the specific error code) then that could be confirmed. It is certainly entirely possible that you could never encounter a specific problem when using WiMP to do the rips (which uses completely different encoders and far less complex math) where the ripper in MC (or EAC or Foobar or any number of other applications) would manifest the problem. LAME (the MP3 encoder MC uses) pushes the system pretty hard in order to generate the best quality MP3 file as fast as is possible!
It is quite unlikely (though certainly possible) that the blue-screen error in this case would be caused by the physical optical drive (firmware or whatever). Optical drives aren't that complex (comparatively) and don't really do much that could cause that kind of issue. If the drive was bad you could get read errors, failed rips, failed burns, and other similar errors, but not really a BSOD. I'd look at these things (roughly in order of likelihood):
0. Drivers or Spyware -- Step one is to make sure the system is clean. Lots of spyware inserts kernel hooks and/or "fake drivers" that intercept system calls and commonly cause blue screens (because they are written badly). Scan your system thoroughly with Spybot Search and Destroy. Remove anything it finds, reboot, scan again. If there is anything it "can't" remove, visit the
Bleeping Computer forums for more help. Also, make sure you have the latest and greatest motherboard drivers for your computer. You can typically obtain these from the manufacturer of the system (Dell, ASUS, HP, whatever), or directly from Intel, Nvidia, AMD, or whomever made the chipset for your system.
1. RAM --
Run Memtest86+. Download the ISO CD-Rom Version, burn a Boot CD (using Nero in Burn Image mode or something similar), and then boot your computer up using it (you may need to go into the BIOS settings and tell it to boot to the CD-Rom Drive) Run the test for at least a good 4-5 "passes" (a few hours). Make sure it doesn't show any errors
at all. If it does, you may have a bad stick of RAM (or it could be something else). If it fails, I might first try bumping up the voltage on your memory (look for DDR voltage in the BIOS settings) by a small amount (0.1v or so). If it still fails, try removing one or the other stick of RAM -- assuming you have two -- and trying again (and then repeat with the other removed). If it fails in both cases, it might not be bad RAM, but a bad CPU or memory subsystem.
2. CPU -- The next thing to test is your CPU (and motherboard subsystem). A good start would be to use the
Orthos Stress Prime Test application (which is a special version of Prime95 designed for testing and which supports dual-core machines), and run it for at least 24 hours. If both this and the Memtest86+ tests pass, then you can be reasonably sure it isn't your CPU or your RAM. In this case, if you get errors it is likely the CPU, though it could be the RAM (but probably not if it passed #1).
3. The next thing to test, and which is a lot more difficult to test without special tools, is your Power Supply. When your computer is ripping discs, particularly at high speed, it ramps up the power draw. If your PSU is flaky or underpowered (did you add a bunch of hard drives and a new video card?) you could be getting power drop-outs that can cause BSODs. If you have a voltage meter and know how to use it, you can test the pins on a free molex plug on the system,
while it is running under load (during the Orthos test for example). Also, if you disconnect the 20-pin or 24-pin connector from the motherboard (you can't do this while it is running obviously) you can force the PSU to "start up" by shorting out certain pins and test the individual power rails for the proper voltages. As I said... This is hard for a "layman" to test. If you know of a good computer shop around town, it might be worthwhile to take the computer in and ask them to test the power supply.
