Solve : replaced power supply hard drive will not boot? |
|
Answer» I installed a raidmax 350w power supply unit into a emachines w1800. The original power supply was 250watts and did not work. The cpu fan runs and the dvd drive DOOR will open but the hard drive will not boot and the monitor remains black. I have tested the power switch. it works because if you hold it down long enough the fan will turn off. I changed the JUMPERS for the hard drive without any luck. I thought part of the power supply didnt work, but it does. I think either the hard drive or the motherboard is bad . Please help as I'm all out of ideas. Thanks I installed a raidmax 350w power supply unit into a emachines w1800. The original power supply was 250watts and did not work. so u mean your harddisk did not boot before u replace 250w power supply to 350w? when you say harddisk will not boot, is it mean your harddisk no respond at all? and MOSTLY is hard disk fail if hard disk not respond at all. why did you replace the psu......to 350watts.......did you consider the REASON why it had a 250watt one??..what was the original problem....The original problem was the computer would not turn on at all. The cpu fan wouldnt even come on. The hard drive did work until the power supply went out. That's why i replaced the power supply unit. The reason for 350watts instead of 250 was at the suggestion of the salesperson I talked to who stated it wouldnt make a difference if i went up in wattage. I just couldnt go below 250 watts. Does the wattage of the power supply make a difference in this case? I can go find a 250 psu if you think that is the problem. Thanks again for helping me with this matter.Having a higher wattage will cause no problems at all.If the higher wattage doesnt present a problem, then the motherboard or the hard drive is bad. How do you check the hard drive to determine if its GOOD or not as this seems to be the easiest way to go? Thanks again.Does anything show on your screen at bootup? Double check all your connections.if its one of these >test it>http://www.maxtor.com/portal/site/Maxtor/menuitem.3c67e325e0a6b1f6294198b091346068/?channelpath=/en_us/Support/Software%20Downloads/ATA%20Hard%20Drives&downloadID=57 if not go to seagates main site and download their hard drive diagnostics.....make sure that you have correctly wired the psu up>......and the ide cable are to......now is the hard drive light on and working....!Nothing shows on the screen, the harddrive doesnt turn and no light at all. I have checked the wiring and its all connected properly. I can download the drive diagnostic tool from this computer, but since i do not own this computer, i wont be able to swap hard drives to see if it will work. I guess i will need to take the hard drive somewhere to get it tested. Would this be the best thing to do or is there something else i can do? Thanks again for your help. It's appreciated.Have you installed a compatible power supply?Not really sure if the power supply is compatible or not. The pins connect properly and the dvd door open and closes so i know its working. Are you saying the psu may not be compatible with the hard drive or the motherboard? Thanks for your help.Have you connected all power connectors to the mainboard? What form factor is your mainboard? Quote Not really sure if the power supply is compatible or not. The pins connect properly and the dvd door open and closes so i know its working. Are you saying the psu may not be compatible with the hard drive or the motherboard? Thanks for your help. Anything that spins (fans, hard drive) is 12VDC. Hard drive and CD/DVD electronics are 5VDC. Door opening and closing just means 12V is working. All LED's are 5VDC |
