Hi thanks for your prompt reply. As my PC is an Inspiron 620 I think your second paragraph answers my question. It just goes to prove that it pays to seek confirmation of anything you read on the internet. I purchased the I7 3770  after reading that it was recommended as an upgrade on this site: [URL] Looks like another mother board might be the answer. Would make it possible to increase RAM at the same time. thanks again. Paul
I am guessing that the CPU was introduced to the market after the manufacture of my motherboard resulting in the failure. I have tried upgrading the BIOs to A08. I have downloaded it and tried to install it. After the initial warning that the system will be altered nothing happens.I was wondering if anyone knew if there is a list of CPU’s that should be recognised by the mb. I’m on the verge of packing it in and buying a new motherboard, any suggestions would be welcomed.
BIOs update A10 doesn’t recognise CPU i7 3770 3.4
