i bought a new motherboard Gigabyte ga-ep43-us3l
i have my core2duo e4400 installed in it............my friend has core2duo e7300 and he wants to sell it to me....so i tried install his e7300 in my new motherboard to see if it works before i pay him.....but after installing the core2duo e7300 my pc just automatically turn offs i dont know why...i checked the cpu support list of my new motherboard here:
http://www.gigabyte.com.tw/Support/Motherboard/CPUSupport_Model.aspx?ProductID=2994%26amp;ver=#anchor_os
and e7300 was listed in the compatible cpu list...but how does that happen? does it mean my motherboard was defected?
well i changed my old cpu back (e4400) and my pc works fine......i really plan to also upgrade my cpu so anyone here knows the problem??Why my cpu wont start after changing cpu?i guess it's an obsolete BIOS version (it's missing the e7300 cpu ID). depending on how long you have your e4400 cpu keep in mind that the e7300 cpu is newer.
launch date of the e4400 was Q2 2007, whilst the launch date of the e7300 was Q3 2008. should you have bought your computer with the e4400 cpu prior Q3'08 you have to update the BIOS. even if you have bought it in early or mid 2009 it is possible that it still has an obsolete BIOS version. an updated BIOS can be found either on the homepage of the manufacturer of the PC or on the Gigabyte homepage.Why my cpu wont start after changing cpu?1. The CPU is defective
2. You broke the CPU when you installed it.
3. The bios is not detecting the CPU correctly. Go into bios and change the settings e.g. multiplier, bus speed, voltage settings to settings of new CPU.Why my cpu wont start after changing cpu?did u put enough (or too much) heat sync compound on the cpu? the motherboard has a built in thing that will keep the computer from starting so the cpu doesn't overheat and explode.
I would also check to make sure you didn't get a defective cpu. it doesn't happen often but it is a possibility.
that's all I can think of.
