hey i have an amd k6 475mhz and it was working fine until i took it apart 2 put a cd burner in. to put a new burner in i had 2 take off half the case which the motherboard was connect 2 to get access to the other screws in the cd drive. after i did this i changed the drive and gave the computer a clean then put everthing back together and turned it on but there is no singal on the montior (it has on board graphics) i then notice then harddrive wasnt turning on then when i unplug the ide cable it turns on. i cant see any reason why this would just happen???? i tryed the harddrive in another computer it works fine so does the ram. please help thanks

Please help some one please

have you connected everything up correct?

yes there is nothing out of place and the hard drive will run if connected to another computer

i just connectec the original cd drive to the comp again and if i unplug the ide cables the cd drive will run and open but if i plug the ide cables back in the cd drive stops and the hard disk boots but still nothing on screen

have a look on the CD-Rom to see if the jumpers are set to master or slave

the cd drive has s,l or a above the jumpers its currently set out on s and i haven't changed it since the comp stopped

are you connecting the IDE cable correctly?
how did you clean the computer?
do you get any beeps when the PC starts up?

i just cleaned the comp with a rag and all the ide cables are connected and there are no beeps

did you clean all the dust off in the machine? if you get no beeps it's sound like your motherboard may be gone
