problem...pc not starting

[builder22]

PC did this yesterday, and has done it again today so looks like something's on its way out...

problem is when I press the power button I get the two tone siren 'nee-naw' sound......switching off at the mains and trying again allowed it to start and boot both times

it's an IP35 pro motherboard, pretty old....when it was doing the siren noise earlier on the display it showed 99, after pressing the power button it went C1...then C3 then 88, then 56...lost track after that

just now it's showing FF while the PC's running, not sure what is normally on the display

the newest component in the pc is probably 7-8years old

any ideas?

thanks, never considered the HDD!

the drives are the oldest parts...one must be 10 years old..storage drive so never had the luxury of a format in a while!
..the progress/loading bar appears and takes forever if I try to change the 'sort by' date/name etc in folders on that drive in explorer so it's a suspect

def has SATA

I can't remember what it is now but the OS drive is 74GB, higher spin speed I think? been so long since I properly took an interest ..

the 'storage drive' is 500GB, think it's also SATA but the OS drive is def better somehow (just can't remember...need to do some googling!)

it's the best thing that could go wrong really as if it's the board/processor/ram I'd imagine it would make more sense to replace everything (considering age/old tech)...... if it's the drive I can take a new one to a new board/pc if something else goes

that's the badger

my pc's been on and off (sleep) since it was first switched on today with no fault, although I'd expect the opposite it only seems to do the beepy siren thing when it's cold, could that be a factor? or coincidence
