hey. Ive just replaced an atx power pack that blew out..when i switched it back on ,evrything is working,cd drive,hard drive is turning.cables are correct..but there is no beep .and nothing coming up on my monitor..it all seems to be ticking over ok.but possibly no communication between hd and mobo.i was thinking it might be something on the mobo..is there a reset jumper or something like this? I replaced a 400w sumvision atx power supply with a 200w viglen power supply if that might be a reason. MOBO-asrock k7s41 hd-maxtor ide cheers.
