I have a PCI POST diagnostic card.... gives you post error code, even if screen not showing... . If you living near Diego/POS I could loan you to test.... for the record I 'fraid ASRock like it was a PCChips (though my current and previous board are ASRock!!)MSI has worked very well for me though...that 'small upgrade' you taking hopefully means a switch to socket AM2. A Dual core processor can be obtained for under $100USD now. Sell the rest of stuff on the trading grounds.
