no power to keyboard, fans, or hard drive

Q: no power to keyboard, fans, or hard drive

I just installed a new k8m800-m7a motherboard. After installing it the computer ran fine. After the first shut down it has no power to the fans, hard drive or keyboard. I have replaced the psuand the power switch. I also used a different power cord. I cleared the cmos to see if that would help but nothing. The board seems to be getting power at least when i plug in the internet the light comes on. Can anyone give me some advice of something I am overlooking.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

We just got 2 new computers, my son has an SATA 120 gig.
Should we have got fans to cool the hard drive?
Some have told me it's a good idea. We got an extra case fan put in, and there's another one on the front...

We both have AMD Bartons, have cases which display temps of hd, cpu and somewhere else in the case(?)
What temps are too high?

Thanks

I wasn't sure whether to post this here or in the DIY forum, but I'm pretty sure this topic is more specific to this section.

In my living room I have a media streamer which is connected to 3 Western Digital external hard drvies (2x My Book Essential, 1x Elements).
I also have this whole wooden structure that on one half has shelves for books, and on the other half has a place for the TV and a few compartments below it.
I want to have the 3 hard drives in one of the compartments, and I fear they might overheat, since this compartment has no openings or vents whatsoever, only its door, which is closed most of the time.
What I had in mind is this: make 1 or 2 openings inside this compartment (going to the back, in the direction of the wall it is placed in front of, so the opening won't be seen from the outside) so that some air will get in and out.
Then, place X amount of small (possibly PC-chassis) fans inside the wooden compartment to keep things cool.

The hard drives' temperature min. and max., according to the Western Digital website:
Environmental Specifications
Temperature (English)
Operating 41 F to 95 F
Non-operating -4 F to 149 F
Temperature (Metric)
Operating 5 C to 35 C
Non-operating -20 C to 65 CClick to expand...

My questions are:
1) Is this even reasonable/possible?
2) If so, how many fans should I use to maintain a temperature where things won't be even near overheating?
3) Which fans should I use for this setup?... Read more

hi,

my desktop crashed the other day, and it was suggested that i get a new computer. so in the meantime, i set up a temporary system from leftover hardware from past machines til i get some money for a new computer.

this temporary system is using a p4ht 3.4ghz processor with 1gb of ram and a radeon x550graphics card on my lanparty 925x-t2 mobo. i booted the system initially without the graphics card and i got the normal system beep and the cpu fan spun and the hdd spun and everything sounded good.
so i put an old radeon x330 graphics card in and started it up and there was no display on the monitor, but everything still was spinning/sounded good. i figured it was a problem with the video card so i got a new radeon x550 from a friend and tried that and got the same problem.
then i transfered everything to an identical lanparty mobo(when i ordered the board, they sent 2 for some reason) and was having the same problem.
so i figured it was the monitor, but i tried the monitor on my brothers desktop and it worked fine.
im not sure what else to try.. any help would be greatly appreciated.. thanks

Several months ago I upgraded most of my PC.
ASRock Z370 Gaming K6
i7 8700k Coffee Lake
Team T-Force Vulcan DDR4 2800 (16 gigs)
EVGA Geforce GTX 970
2tb SATA hard drive

This was all running on a Corsair 500 watt power supply. Now a couple days ago I decided it was finally time to upgrade, so I bought another 16 gigs of the same RAM listed above and a Seasonic Focus+ 750 Gold power supply. (I think) everything is hooked up the way it should be, only now it's sounding like my hard drive doesn't want to turn on. It'll make a whir like it's trying but then it just makes a sound like it can't turn on. I'm assuming this is the problem because my motherboard can't detect the hard drive, and it's still plugged in the same spot I had it originally when it was working. I believe it was slot SATA3_0_1.
Faulty hard drive? Or hopefully I'm doing something wrong so I don't have to screw with returning it.
Any ideas would be warmly welcomed!

So I have an ASUS P4C800-E motherboard in a system that a built a few years back. It worked fine but the system has been sitting in my basement for a year or two unused.

I decided to take the components and drop them in a new case.

I have hooked everything back up properly (i think) but when I hit the power button, the cpu fan, power supply fan and case fans turn on for a brief second and then shut off. (the green standby light on the motherboard is on)

What do I do?

I think you can tell from my question I am exteremly amatuer at this. Simple explanations please...
 

A:Turn power on... fans start up then power shuts off in 1 second

With it shutting down after 1sec, I would check that the hsf is plugged in and working. If there is no fan input ie fan speed, most boards shutdown. In addition that the hsf is installed correctly. If it is loose, etc you will have problems. Most of the time when the hsf is loose, it shuts down in about 5~10sec not 1sec. I tend to think it is more of a shorting problem of the board to the case.

If that is not the case, I would attempt to pw ON the system outside of the case. There are complete instructions in a guide at the top of the forum. It is called troubleshooting guide for problem builds.

Well shoot... this is probably gonna be the best place to ask, besides maybe instructables.com or howardforums. But seeing as how I hardly meddle in those places, I will start here =)

My situation - I have softmodded my Wii, and am currently using a 30 gig IDE hard drive to run disk backups of a few games that I own. For data, I use a IDE/2.5IDE/SATA to USB adapter I got off of ebay. Works great. But the low price, it did not include a power cable.

To power the drive, I found out that you can short the green wire with any black wire on the 20/24 pin block of a computer PSU to have it power on when it is plugged in. Using a molex lead, I power the harddrive.

However, this is very cumbersome.

What I want to do, is use a combination of the 2 usb ports on my Wii and an external USB battery I made (altoids battery charger, runs on 4x NiMH rechargeable AA's). The hard drive needs +5vDC over the red wire (@.63A), 2 grounds, and +12vDC (@.35A) over the yellow wire.

My current idea, is (this might actually work): Use the altoids box to provide the +5v (it actually outs 4.8v but for all purposes, it has charged whatever I throw at it), and use the 2 Wii usb ports + 1 or 2 NiMH batteries (@1.3v) to provide the other +12v. (one batery would give 11.3, and 2 would give 12.6)

I suppose I need to get my father's multimeter for this project.

Anyway, does anyone have some solid ideas for this?

OH ALSO ONE BIG THING - As I stated, the Wii has 2 USB ports. One is specif... Read more

It's called the circuitboard. To replace it you will need to take the circuitboard from another identical hard disk, they just screw on and are easy enough to swap. It might be easier to get someone to solder the +5V connector back, though.

I can't seem to figure out how to perform this operation, so I'm coming here for help.

I was told that I could go to control panel, then power options, then somehow command my hard drive to power down after so many minutes of inactivity. All I would have to do is tap a key or wiggle my mouse to get it back up + running. This is supposed to be less stressful on my hard drive as it's on 24/7.

Right now my power scheme is always on, monitor is always on+hard disks is always on. I'm assuming hard dddisssks is the same as hard drive?

I do have a standby button on my keyboard. What is the difference between standby mode versus doing something different with the power options in my control panel? I did try the standby button last night + the power button on my CPU flashed for a while, then went back to its solid color as it is when I'm working on my system.

Looking forward to some good input here as always.

A:How Do I Power Down My Hard Drive?

The following is an excerpt from this article."Quick: What's the difference between putting your PC in Hibernate or Standby mode? Yeah, we weren't sure either. Luckily the Productivity Portfolio weblog schools us on the finer details of Windows XP power schemes. Using Standby: Your machine recovers quickly as your data is stored in RAM. The slower part is waking up the peripherals. Although your machine is in "standby" the power has been cut to items such as your hard drive and monitor. You're running your machine in a very low power mode, but it is still on. This mode can be useful if you're on a notebook and need to conserve your battery while you step away.With Hibernate: The big difference is that your PC has shut down and is not pulling power. Another difference is that your data is saved to your hard disk and not RAM. This makes it a safer, but slower option for shut down and resume.Not all PCs have the capability and are configured to Hibernate. If yours is, to see the Hibernate option on your XP shutdown screen, hold down the Shift key when you shut down."To enable hibernate go to the Control> Power Opttions> Click on the Hibernate tab and enable hibernate.To enable sleep mode right click on your desktop> click Properties> click on the Screensaver Tab> in the Monitor Power section click Power> when that window opens up, click the Power schemes tab .

I am running a 1600 MHZ AMD processor with 1.5GHZ of RAM, a CD & DVD burner, two 80GB hard drives, a card reader and a floppy. Do you think a 350W power supply is enough?

Also..I'd like to get some replies on a Fortran power supply I'm considering using. I'm not all that crazy about Antec's anymore and when I ran a recent test to compare the two I noticed the Fortran (350W) blew out cooler air and more of it than the Antec, even though the Antec (400W) cost more. Also the Fortran I'm considering has only one (big) fan compared to the Antecs two. What kind of difference does that make?

I've checked out task manager and the cpu isn't over-utilized, and neither is it hot...I held my hand over the fans and they were blowing chilled air. It's scaring me because I have no idea how it happened, since it just happened while it was on. I even updated the UEFI, but that had no effect.

Hi!

I went to the lab to work on a digital photo project today and my external hard drive won't turn on! It is a Coltech and says "3.5" Hard Drive Enclosure" on it. It's one of the ones that has a USB and a power cord to plug into an outlet, and an on/off switch to turn on the power.

So I plugged it in, put the USB into the iMAC I'm using, turned on the switch... and it won't turn on... no power at all... normally it makes little noises when it turns on, but nothing.

I checked all the connections, both ends of the power cord and USB. I tried it in another iMac. I tried plugging a desk lamp into the wall to see if it was the electrical outlet... everything was fine...

A:HELP! My external hard drive has no power!!!

It might just be the power adapter or the enclosure that has died. You might be able to remove the hard drive from the enclosure and either install it internally in a computer or put it into a new enclosure. Most computer places sell enclosures if you need it in a hurry. Hopefully its not the hard drive inside the enclosure that has failed, in which case you hopefully have the all-important backups of your data.

Thx Dace
 

A:Hard drive or power supply?

I'd put money on a software problem. Is there anything specific that causes the lockups? Like opening a browser or running a game? Without a specific trigger for an error it's harder to troubleshoot. Two things you can try: first is safe mode. This will load generic drivers so you might quickly identify if it's software or hardware. Use your error trigger if you've got one. Once you've done that, you can move on. Second is identifying the offending driver or component. For software, you must uninstall drivers one at a time. I'd start with simple stuff like mice and sound. Reboot after each uninstall, and again, use the trigger. For hardware you've got to physically remove things one at a time. Same deal, reboot after each, until you've defined the problem.

One more thing, have a look at the event viewer. right click my computer, select manage, and it should be there.

I have an older Dell PC, and I ran into a roadblock while trying to add a second SATA2 hard drive. The problem is with the available power cables. Its my understanding that the drives need to be hooked up in series in addition to setting the pins on the slave drive in order for them to function correctly. Is this right? The one spare power cable I have with series connectors is too short to reach the bottom of the case where the drives are (its actually designed for 2 CD/DVD roms and a floppy drive, but I'm sure it would work if it could reach!) I spent a while going through newegg.ca's inventory and unfortunately I can only find Y-cord splitters which would put the drives in parallel, not series. Would anyone be able to help me find what I need? Secondly, I was wondering what the difference between the 5 and 4 wire power cables. My system has 5 wire cables (red, orange, black, black, white) while all of the ones I see on newegg are four wire cables. Are they interchangeable, or would I need a converter? Any help or clarification would be greatly appreciated.
 

A:2nd hard drive & power cables

SATA drives have no slave or master designation, and no need to set jumpers.
For power, you need a Molex/SATA adapter like this one:

Here's the problem: My old internal IDE hard drive is in a computer that has power problems; I know this, because there is the smell of smoke inside, coming from the power supply. This computer was given to me. The computer will not power on, but the hard drive is supposed to be good. I've swapped out the power supply with a known good one and therefore have isolated the problem as either a button or button wiring problem(button will not fire). As you know, whenever there's a power problem, it is also possible that there's also a motherboard problem, so fixing it so that the hard drive works in this system may not be possible and if it is, then it maybe akin to buying another PC. I have another PC. However, I know that most hard drives are not swappable into other systems. How can I, at least, recover those files and ,after that, implement that drive into Windows 2000 as a second drive? I know about jumper settings and hookups. Any other help would be appreciated. Thanks!
 

A:Hard Drive Recovery when PC will not Power On

Most HD's are not swap'able into other systems as the Primary, or C: drive. They can be attached as a slave drive, or on the secondary controller. So if you do have access to another PC, put the drive in as a slave to the current master. Then you can copy off any data you want....that's not corrupted.

I realize that this is not exactly a computer issue but here goes. I'm using an old computer power supply to power quiet 12 V cooling fans for electronic equipment in an entertainment unit. I am running 3 120 mm fans that draw 1.4 W max. with a 200 W power supply. I have 2 old PS's, the oldest has a switch that will turn it on and off but has a noisy cooling fan. The newer PS has a quieter fan but won't turn on (I'm guessing) without a signal from the motherboard; it worked OK before I removed it from a computer. My question is two part; can I disconnect the cooling fan in the older PS since I'll be using less than 5 W of power total without overheating the PS? Alternatively is there a way to "jump" the newer power supply so that it will turn on without the motherboard connection? Thanks

One night this happened and I noticed next day that power LED on case was not green as usual and when I tried to turn on machine, the HDD light on case lights, fans (power supply and cpu) come on and floppy lights green, but no display, hdd sound or cd lights. I have tried removing cmos bat to reset, I have tried booting with nothing on mb, but mem, vid card and still same problem. PS/2 keyboard lights briefly when I plug into mb, so I know mb is getting power. Any help is greatly appreciated and I hope quickly! Thanks!

I just purchased in many PC in a really cool metal case. when I got home I realized that system did not have any kind of fan and I figured this was alright because of its size. later I noticed that the system was very hot (touched w hand). I opened the case and noticed there was the ystem fan pins on the motherboard so I grabbed of the many that I had lying around indused sugru to attachet to the top inside of the case. so far it works really good and everything is fine. but also have these two smaller fans that fit perfectly into beside cutouts of the case and I think would look really cool and also provide further cooling. so I have both fans in the spa so I want them, but I'm not sure what the best route to take and it comes down to power in them neither of them has any plastic suck it on the end of the wires but both have just wires. what my best option would be to strip the wires back a little bit, and cut out little strip to Windows bare wire on the main sys fan's cables, and solder these to them? Would there be enough power provided for the 3 fans? Amy guidance and advice is greatly appreciated. Thank you!

Hi,
I have no idea but if you look at your power supply and post the watts it has possibly someone might be able to assist
There should be a tag with what watts it is
Cheers.

I was thinking about when I play games at my desk, my mouse hand sometimes get's a little sweaty from heat, and how nice it was to mount a extra fan to blow on the shelf that my keyboard and mouse sits on. Would a 80mm fan be able to run adaquately useing power from a USB port? Any guides on useing a old cable to grab power from the USB port?
Here's a good tip for anyone who has a side mounted fan: I noticed that the side mounted fan built to blow onto my heatsink from the side of the case was just exiting out the exhaust and doing nothing to cool my cpu.. I fixed this by cutting the bottom of a old plastic cup, then electrical taping the cup to the side fan so that it funnelled air straight to the sink, this dropped my cpu temp a full 5 degrees C!

Hi Folks,

Is the power available from the PC power unit spread equally across all output cables?

I have already used all the cable connections for internal devices (HD x 2, DVD...etc) and already have a Case Fan runing off a male / female connector into one of the HD leads.
The CPU fan runs off of the Motherboard.

I was thinking of adding fans to the HD's, but that would mean 1 of the power leads would be running a HD, a Case Fan, and a HD Fan - is this going to give me problems? such as on start up?

Any advice welcomed please>

Thanks
Hew

This problem has me stumped , my grandma's computer will not power up. I think she had a power surge because when I open up the power supply there was a burn mark on the circuit board and bottom of the circuit board case. The old power supply heated up so much a capacitor unsoldered itself.

I chatted with a Gateway tech support person and the said that is was the power supply and so we ordered one from him and installed it. The computer still would not boot up, I check that I had everything plugged in, the power supply switch was on, and that there is power to the outlet.

I did notice that there is a green LED on the motherboard that is lit up and that light was not lit up before the new power supply was installed.
If someone could give me ideas that would be great.

Thank for your help
 

A:Computer won't power up AT ALL (No fans)

It's not unusual for a dying power supply to take other parts down with it. The motherboard is generally included in the victim list. It's likely that you are looking at a torched board. However, there are a couple of things to check before you give up on it.

Look inside the case for loose wires, disconnected harnesses, etc. If you find nothing there, I would do an out of case build to eliminate shorts or a component problem. You can find instructions here: http://forums.techguy.org/hardware/580000-troubleshooting-guide-problem-builds.html
Try that with your new power supply, and report your results back.

I have Windows 7 installed on my new computer, but my firewire audio card and also some software wouldn't work properly with it, so I put my old hard drive with Windows XP installed on it into my new computer.

I can boot up Windows XP from the second hard drive at the bios screen bit, but when it gets to the log in screen, the mouse and keyboard will not respond. I have tried multiple mice and keyboards including the old school style non-USB keyboard. The keyboard works fine to press F12 to get into the boot menu etc but then just stops working completely when XP is loaded. I assume its some kind of driver issue or something like that but I'm pretty useless with computers and I have no idea how I can get my mouse and keyboard to respond in XP

Please if anyone knows how let me know, thanks!!

A:Booting XP from second hard drive Mouse/Keyboard problem

I was thinking about maybe if I copy and pasted all the drivers from my C: windows folder into the windows folder on my D: drive (old hard drive). Maybe this would let my mouse and keyboard work? I'm a bit worried though it seems like the kind of thing I do that seems like a logical idea but actually screws up my PC

Hi,I am planning to order a P-51 laptop and I have made up my mind on which options I would be going for, which is listed below from my cart... Now there is an option for me to choose a first hard drive, 500GB HDD 7200rpm, for zero cost, in addition to my ordered 1TB SSD as a second hard drive...  My main concern is that I need to make sure that you will install windows on the 1TB SSD, and NOT the 500GB HDD... Is that an option...?! I am afraid that if I order the 500GB HDD 7200, that you will install windows on it, since it is labled "First Hard Drive"... This is why you will see that so far I have not included the 500GB HDD in below configuration. Also, is there a chance to get Arabic letters on my keyboard?!..  in addition to the English letters of course... Hope I make some sense in my question...Thanks.Sameh  Processor : Intel Xeon E3-1535M v6 Processor (4 Cores, 8MB Cache, up to 4.20GHz)Operating System : Windows 10 Pro for Workstations 64Operating System Language : Windows 10 Pro 64 for Workstations EnglishDisplay : 15.6" FHD (1920x1080), IPS, 10-point multi-touchMemory : 32GB(16+16) DDR4 2400MHz ECC SoDIMMGraphic Card : NVIDIA Quadro M2200 4GB GDDR5Base : NVIDIA Quadro M2200 4GBColor Sensor : With Color SensorCamera : 720p HD Camera with MicrophoneThinkpad Pen : ThinkPad Pen ProKeyboard : Backlit Keyboard with Number Pad - EnglishPointing Device : 3-button TrackPoint pointing device and 3-button multi-touch touchp...

Hi everybodyI have an h8-1400ef that worked without problem.The system is on a hard drive SSD of 248 GB,The data on a disk of 1 TB.Having a second disk of 1 TB identical to my data disk, I wanted to create a raid 1 of 1 TB.In the Bios I find how to switch from AHCI to RAID, but can not find how to declare the geometry of the RAID.I then had the idea to update the BIOS of the PC by downloading the sp68932 which corresponds to the most recent version for my PC.The operation went well but after the reboot my PC no longer recognizes the screen, the keyboard. Only the ON / OFF button light and the fan will operate.Of course I tested the screen and its cable on another machine.I tried what I found on the forum:- switch off, disconnect the power press the ON button for 5 seconds- switch off, disconnect / reconnect all connections.- clear cmos (you never know)- and http://support.hp.com/us-en/document/c04126730Nothing makes the screen is definitely unknown and the wired USB keyboard too (the numlock or capslock light never turns on).I'm a little desperate, if someone has an idea ...

I am going to download some shows from my DirecTV DVR the legal, old-fashioned way. Play at real-time speed through 3-pt RCA cable to an RCA-USB adapter to a portable hard drive. Problem: Supplying power to the hard drive if none is going to the USB port from the DVR through the old-style RCA output.
My computer is too large to move and the DVR is almost in constant use (another reason to save the cartoons, cooking and woodworking shows before it dies), so a $80 portable drive is a better solution than moving the equipment.
I could use some advice/education on this. Thank you.

old power supply crapped out, bought a 580 watt one

Mobo ks8-la Salmon .. (from a compaq)

New power supply does this:

Get video, cpu, fans run, mobo runs fine, can go into bios and have the hd not recognized . hard drive "click click" .. no "vroom vroom"

Found 15 year old 90 watt power supply .. no cpu, no fan, no video, no bios .. hard drive spins like it has never spun before. It makes the noise as if it's loading and brand new.

Now, might I add this mobo has this extra 4 wire lead that plugs in.. has 2 yellow, 2 black wires. The old power supply .. doesn't .. Not sure if it even matters, but I'm sure the more detail you know, the better.

cleared cmos, tried cable swaps... nothing.

Any ideas or does anyone need more detail?

I recently had a new hard drive installed. I started getting a notice on every reboot that "the AC power adapter is not recognized and it could impair system performance". I hit F3 to not see the notice again. I haven't noticed much, except that today the screen completely froze once and I had to do a hard reboot. Should I be looking into buying a new power adapter?

The power in my flat turned off because I forgot to get credit and it seems to have damaged my Lacie 1Tb external USB drive. Windows seems to have stopped seeing it in my computer so I have done the following so far

1.Plug in and turn on the external USB hard drive
2.Right mouse click on My Computer
3.Left click on Manage
4.Left click on Device Manager
5.Expand the USB list
6.Find the USB device
7.Right mouse click - Uninstall
8.Turn off the external USB hard drive
9.Turn on the external USB hard drive and let it find and install the driver
Windows refuses to find the driver and returns "This device cannot start. (Code 10)". I can here the drive platter spin and the drive lights up so I think the power is ok. Can anyone help please?
 

A:Hard drive issues after power outage

Gotta get a UPS my friend... save yourself a lot of hassle.

If the drive was busy at the time the power was cut, the filesystem could be corrupted. My recommendation is to use any recovery software that was bundled with the drive. If this isn't available I would try the drive on another system, perhaps one with a different OS. If you still can't get it working, try downloading the interface drivers from the manufacturer and install them manually. As a last resort you can consult tech support directly but if you don't have any luck, you may be looking at a worse scenario I'm afraid.

If all else fails it may be time for disk diagnostics...

Hi,

I recently aquired a new molex-sata adapter for adding a second HDD to my computer, but when I plugged it in and turned the PC on, it won't power up. Without either hard drive plugged into the power supply, the PC will start but obviously go no further, but with either hard drive plugged in the computer simply won't start.

I've tried with three molex-sata adapters now and none of them will make it work, so I was wondering if it is likely that the new adapter has ruined my hard drive? If not then any tips for fixing it?

Thanks very much
