After replacing a blown out motherboard, my Toshiba Satellite C600 is still malfunctioning lately:
BSODs.
Distorted graphics, and freezes.
Sudden shutdowns.
After removing the battery and doing a re-format the laptop works perfectly (I should mention the problems continued before removing the battery after the re-format). I haven't seen a fault while solely running on A/C power for two days. Could the problem be a faulty battery?
If your computer is malfunctioning in different ways; surely there's something going on with the hardware. You've been experiencing actual crash dumps, corruption of graphics, your computer managing to hang / freeze / stutter / ... and even just suddenly ...poof... turn off.
Since you've shown your battery solved this as well as not the re-install being the cause, power is involved in this situation. Let's put this problem aside for a moment and look at a typical hobby of geeks and nerds... Overclocking!
Overclocking isn't just pressing the pedal of a car, as you can see, the voltage you give to the component you're trying to overclock does also matter... Stability.
Increasing the voltage level does not only result in stability, but also in temperature. That's why setting the voltage carefully while overclocking is in an important thing to do; too low and you risk having a stability problem and too high and you burn the component up.
Wait... That sounds familiar, your motherboard might have died because of that reason.
Your laptop suddenly shuts down to protect the most important components from burning up; if they get really hot they can get unstable as well due to thermal agitation of electrons, which is why you're experiencing graphical corruption and/or freezes. Sometimes your computer notices such corruption is going on, or the GPU shuts itself off, that's where the BSODs come wrong.
Bottom line of the story, your battery is giving an incorrect amount of voltage / ampere; yes, it can cause your laptop to malfunction. I'm basically using my laptop without a battery because my battery blew up (luckily while not in the laptop) after showing the same characteristics as your one; and sadly, I can't find a cheap new one.
What do we learn here; batteries aren't perfect either, they can blow up.
It's probably a good thing you're no longer using the battery, who knows what would've happened?
I know this is an old forum but I wasted a lot of time trying to diagnose what was wrong with my laptop, so hopefully I will save someone time if you have the same problem. My laptop battery died but other than not holding charge for very long, I didn't think it was a problem. My CPU sat around 60% and would easily reach 100% from the smallest task. My keyboard locked up and did not work, and my DVD drive was playing up. I had trouble updating my anti-virus software because of other issues but my laptop was seldom connected to the Internet so it didn't bother me. I finally got around to updating my anti-virus software and found a trojan which I thought may have been causing issues. I also had many files missing after doing a disk defrag so wasn't sure if that was also causing a problem. In the end, I decided to format my hard-drive and the problem wasn't fixed. I was a little suspicious that my battery was causing the problem so after removing it and only using my ac adaptor, the problem disappeared. It seems a stuffed battery either drains the power, or when the battery is in and the adaptor is connected, the laptop is only getting the power from the battery, and if the laptop uses the power quicker than the battery can recharge, then the laptop freezes. Wish I knew that before I formatted my hard-drive.
