Compaq deskpro won't boot

can you hear any fans running
any lights come on
does the computer beep at all - or is completely dead

if completely dead
check the power lead is correctly plugged in
if applicable in your country - check any power fuses
make sure the switch (if it has one) is also on at the back - some PCs have on-off at from and a master switch at back

 

are you sure the power is getting down the lead.
i dont knwo th ecountry you are in or what connectors you use.
for eample does the power lead to the screen have the same connector if so AND THE SCREEN WORKS - swap the screen cable with the computer box cable - see if the screen works OK
when i say works any lights on controls come on

 

The PSU may have blown - no fan running - or something maybe stopping the PSU from running.
how do you feel about opening the case and pulling cable around.

may be if you disconnected the PSU cables from the motherboard, Harddrive(s) floppy etc and see if it starts with no conenction - if not then at the least you need a new PSU.

 

sounds like PSU - any fuses on the back - small black caps - i have seen a while back some fuses - but not looked recently.
whats the wattage of the PSU - I dont know if these are bog standard PSU or special compaqs.

post the model number - maybe we can find out.

in the states I think HP has a spares website you can order parts from.

what country you in

 

that wattage is low - would have thought it should be 300W plus.
looking on web at that part - they say 200W
you didnt add any devices when it stopped working

bog standard - if you could go to your local high street computer store and buy a 350/400W PSU - 4 screws to hold it in and fits ATX.
