How to Use Debugging Tools To Analyse .DMP Files?

Reader Question:
“Hi Wally, How do I fix this Blue Screen Error. I’ve done everything, but I still keep getting this error. Is there a way to fix this from .dmp files?” – Many Users

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.
