Hi, can anyone help me?? i took my A4000 apart (again) to clean it. but now i have a big problem! my comp wont boot at all! my floppy is pulsing?? and wont load anything or activate the light! my computer just seems dead! nothing is working at all! can anyone give me a clue? I have an A4000 with a 60gigHd PPC200mz060 and 120mg ram(well mostly i have 111 coz a second after bootup it looses some??) think thats the ppc board? i use a 52speed cdrom and a picassoiv board and have onboard scsi card GVP. i have taken this Amiga apart b4 but this time something has gone very,very wrong!! please,please help!

at this moment nothing works at all, the fan comes on, on the power supply, the ppc fan turns on. thats it, when i turn the amiga on, i hear the hd spin up, then the cd light flashes once and then.......nothing. thats all it does. i tried removing everything and turning it on and still nothing. i think the power supply might be faulty.

will have to look at the cyberstorm to see if its fitted right, but the keyboard ligh comes on (caps lock) comes on and off when pressed.

ok, my amiga now works, the problem was with two 32meg chips on my ppc board. they were from a local computer shop and never really fitted right, i removed them and it started up, but i have no hd light anymore and my diskdrive is still not working, i removed everything from my case, then put it all back together on bit at a time.
