i once changed the motherboard for my Sempron 2600 and i thought i could just keep my files and no problem there ... and suddenly i had 2 sets of drivers and had to reformat anyways ..
And i forgot about CPU thermal grease when changing the Sempron 2600 so i was in wil panic when it would not boot but i knew why i just didnt have a store i could just buy it in ;)
And i tried washing the heatsink with water ... not a great idea ... all the dust got trapped and did not come out ... took me 1,5 hour the clean it . ;)
^^ Same pc ... :D
