pc wont boot up

[cf van man]

hi iv got a emachines p4 with a intel d845gvsr board ,the dam thing wont boot up,theres no fan movement,no beeps,iv checked the psu with another,no joy!,iv done a bare bones start up ,but still no joy,iv got a green led light on the board, so i checked to see if what voltage there is on the board,5.68v(standby)when self test on psu 11.8v on yellow/5.4v on red/3.3 on others.iv also got 3.3v going to the sw+3.3v when sw pressed ,iv checked most of the board resistors all fine ,but between the battery and graphics chip theres a item that stands about 10mm high covered in plastic and looks from the top like a cylinder type fuse which has no continunity through it any ideas plz!!

Well I doubt thats a fuse, cylindrical components are usually capacitors.
I saw an emachines computer just like this the other day, turned out to be a dead mobo in the end. Sounds like you've checked everything, might want to try resetting the BIOS and if no luck remove the ram and all devices and see if the board beeps when powered on.

if you can get the same model board you won't have to reinstall windows but its up to you,
