Blue Screen of Death

When I first got my Alienware 17, each time the laptop was in a low percentage of battery, it changed to a sleep mode in which I was able to recover after I plugged in the charger. However, some months ago each time my laptop had its battery low, it turned off instead of going to the sleep mode.

One day, after my laptop discharged, when I was turning it on again, it showed a blue screen of death and said that windows couldn't start. After using the automatic fix tool, I was able to initialize Windows again. But, I began to notice that the CPU fan (the left one) began to work almost at its full load because of its heavy noise, even at times in which I was just in the Windows Desktop. I also noticed that the battery percentage viewer became crazy, because it showed that the battery was at 99% for an entire hour many times, and it discharged when it showed sometimes 50% of remaining battery.

Again, one day the same thing happened when it discharged, but this time the automatic fix didn't work. The BSOD showed a 0x3B error, but I couldn't manage to fix it. So, I had to use the factory reset to fix it, losing all the information I had. I thought it was fixed, but the same thing about the fans and the crazy battery remained. And, again, my laptop discharged and the BSOD appeared. Factory reset and the problem remained. I've had to factory reset my laptop like 5 times by now, so I'm tired of doing the same. I want some help to get it fixed. Thanks.
