Dell Inspiron n5010 Blue Screen Problems


Questions
I have a Dell Inspiron n5010 (dell batteries for inspiron n5010) that has been used for about half a year. I have Windows 7 on it and it has just brought up the blue screen of death. Today when I turned on my laptop, it brought up a black screen to do a three step check on the C: system. I then logged on and the blue screen appeared. I did a scan with McAfee and no virus were found.
Any suggestions on what to do? I've never encountered the blue screen before.

If the problem persists, did you check if it could be your Dell Inspiron n5010 laptop power cord or power source problem? Defective or insufficient power supply might cause error messages that are misleading. Take the battery out and power on your laptop with the charger only. Make sure your laptop power jack and charger plug tip are securely connected. Did you notice the power jack loose? You can find laptop power jack on ebay. Fixing and soldering the power jack requires professional skill though. The charger green/blue LED should be on. If not, replace the defective charger.
