    Upgrading from E4300 to E5700 causes machine to hang at boot.




      I just bought a LENOVO ThinkCentre Minitower M55e 9637-Q2U Desktop, Intel® Core 2 Duo E4300, 2GB, 80GB,CD-RW/DVD combo, Windows XP Professional machine, and I wanted to upgrade to a E5700.


      Both processors seem to be lga775 so I did not think it would be an issue.  I bought a new processor, and installed it in the lenovo, but then the machine will freeze at boot.  I can't access BIOS, nothing... no beeps or other indicators that anything is wrong, just won't go past the post screen.  I put the old processor back in and it boots up fine, no issues.


      I updated the BIOS to the latest version http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-66778 and shut down the PC, installed the new CPU again, same issue... is there something im missing/can try?


      Thank you!
