Windows 7: BSOD after upgrading CPU

BSOD after upgrading CPU

Ok so i bought a new CPU off of amazon the other day it was a Athlon II X4 630 and I got it in the mail and installed it today. Well I decided to try and put my other stick of ram(2x4gb) in to see if it would detect as dual channel with this CPU and to my surprise it did. I tried booting into windows and it just kept restarting. One time it gave me a blue screen saying Machine Check Exception. After that one it would not give me any other blue screens just kept restarting as soon as it hit the login screen for win7. Then I took the other stick back out and it logged in for a few sec and started to load windows and such then it restarted with a bluescreen giving me this error code 0x000000124. Any ideas what the problem is? I also just reflashed my BIOS with the latest version via USB drive. And safe mode doesn't work either.

When you replace or upgrade a processor it is necessary to Clear CMOS or reset the Real Time Clock.
Most older machines have a jumper on the motherboard for doing this. Some newer boards have a switch in the back. Consult your motherboard's manual for the location of the jumper.
Sometimes the jumper is marked ClearCMOS, sometimes CLRTC. Both are the same.

For an Asus motherboard it goes like below. Other boards are done pretty much the same:
  • Note all your current BIOS settings
  • Shut down the computer > remove the power cord.
  • Remove the 3v battery.
  • Move the CLRTC jumper from pins 1-2 to 2-3.
  • Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
  • Put the CLRTC jumper back on pins 1-2.
  • Replace the 3v battery > replace the power cord > boot.
  • Immediately go back into BIOS and reset all your preferred settings. If the CLRTC worked you will need to reset the date and time.
See if that works.
