mouse, keyboard, and monitor not working after power surge (Moved from Windows 10)

Q: mouse, keyboard, and monitor not working after power surge (Moved from Windows 10)

My PC worked fine lsat night. I went to bed and shut it off. Last night there was a power surge. This morning I turned my PC on and the lights inside it and components turned on, but my keyboard, mouse, and monitor do not turn on.

I brought my computer into my brother's room and tried his equipment with my computer and everything worked fine. Though when I brought it back into my room, none of my stuff still worked. When I plugged my peripherals into his computer, everything worked fine. When I plugged his peripherals into my computer in my room, none of it worked.

I attempted to move my computer back into his room and use his gear to play some games, but now none of his gear works on my PC anymore.

I'm assuming that my computer instantly boots into some sort of BIOS/ Safe mode and therefore doesn't power the keyboard, mouse, or monitor.

Also, I had this same issue about 2 months ago and brought it to a PC repair place. They couldn't find anything wrong with it and handed it back to me about two days later. I plugged it back into my same mouse, keyboard, and monitor that I have today and it all worked fine.

Any help would be appreciated.

Preferred Solution: mouse, keyboard, and monitor not working after power surge (Moved from Windows 10)

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.

My son just returned from holiday and powered up his gaming pc. It powers up ok but no signal to the monitors, keyboard or mouse. The fans work, the storage hard drive is spinning, dvd drive has power, graphics card has power lights on and when an additional external device is plugged in then it gets power from the same port that the keyboard or mouse is plugged into. Picture attached of system with power on.

The monitors work with another computer, as do the keyboard and mouse. No visible damage to the motherboard. Worked fine before the holiday but not on return. Was left plugged in.

Have tried disconnecting everything, power drain, removed ram and retry with one slot filled each time.

Windows 10. I can post the full build but was wondering what the trouble shooting order for this kind of problem should be?

We built the pc a couple of years ago. Running with no problems. No software changes prior to going on holiday and was working fine. Neither of us are super experienced with tech troubleshooting but not afraid to get stuck in. I actually enjoy it, my boy just wants to play some games.

No library of spares hanging around, so I wanted to start with the most likely stuff first.

Searching online points to PSU, CPU and ram as places to start. Any recommendations as to the order?

Any suggestions most appreciated.

im in the middle of moving im currently at a friends house i decided to setup my cpu and go play a game i plug in the cpu and take my friends computers monitor and keyboard and i go to boot up my pc and it seemed fine for a minute the lights on my pc came up the lights on the back came up the keyboard flickered with the lights then nothing no picture on the monitor no keyboard response or mouse response its a standard ps/2 keyboard and mouse the standard ports for em the video card i have is a nvidia 6800 ultra 512meg i cant figure out what the problem is my friends pc works fine but mine seems to not respond to anything i thought it might be a motherboard failure but the lights on the back came up and when i opened it up the lights came on i thought it could be a problem with my power supply or the fact that thiers 2 surge strips so close to each other with a ton of stuff on them

i use windows xp home edition

A:monitor mouse, keyboard no power

If you have been moving the computer you need to check all the components and make sure nothing was dislodged and all are firmly seated. (CPU, ram, video card.) and make sure all the power connections are firmly seated.

I installed a nic card and everything worked fine. I changed the slots that I had the nic card and video card in and now when I turn the computer on I don't get any power to the monitor, keyboard, or mouse. I tried to switch to the on board video and it still didn't work. I left it alone for the night and this morning I tried it again and the monitor worked for a minute with the on board video but not any more. Are there any ideas I really don't want to replace the motherboard. Thank you guys for your time.

A:no power to anything through cpu. (monitor,keyboard,mouse)

Are the fans running? Double check and see if by chance you unplugged something.

If the fans are running when you power up, try removing the cmos battery for about 15 minutes and then put it back. Now try to boot the computer.

I am came home from work one day and the BSOD was on the screen. AFter that no signal to monitor, no power to keyboard or mouse. So i thought maybe the vid card was out so i put in a new one - nothing. So i replaced the motherboard battery - nothing. Need help, hard drive crashed? motherboard shot?

A:No signal to monitor, no power to keyboard or mouse.

Sounds like a mobo problem to me (assuming you're gettting some power to the motherboard).

Do you get any beeps when you turn it on? Are you fans spinning? Tell us exactly what happens when you hit the power button.

And more importantly, if you want some help you have to fill in your profile and tell us your system specs.

Hello, I recently came home and my computer wasn't working properly. Everything was turning on like normal, and everything sounded normal, except I had no signal on my monitor, and my keyboard/mouse weren't getting any power. Sometimes I will get lucky and the keyboard/mouse will randomly start to work, and I am able to get into my computer, until I shut it down before I go to bed, then It doesn't work once again. When the computer is on and I slowly insert the USB Mouse, I can see it light up then it fades quickly. I have tried different mouse/keyboards and still have had the same issue.

I checked the capacitors and everything looks fine. I have also tried draining the power or whatever (Holding down the power button while it is unplugged). I have an ASUS A8N-SLI Deluxe for my motherboard, and I have a NVIDIA 7600 GT for my graphics card. I can see the fans spinning on the CPU fan, Chipset fan, graphics card fan, PSU fan. Please help!'

I have been reading online about hearing "Beeps" I have not heard any, nor do I recall hearing any before this problem happened. I need to remind you that my computer was untouched in my room and when I came home I found this problem.

My Dell is only about a week old and now this is what happens when I start it (yes, I have contacted dell... i want to know exactly what hardware is failing so i can make them send me a replacement):
-Instead of the normal blue light I get the yellow light on the power button.
-No power to keyboard/mouse/no signal to monitor
-hard drive sounds like it is working
-sounds like one beep when i turn computer on (not sure if that's normal or not)
-CD-rom works: it will open and close when I press the button
-Power supply fan and CPU I believe are both running
-One fan however used to make a "roaring" sound when the computer first started... it no longer does that... not sure which fan that was though.

What steps can I take to figure out the problem? I've opened the computer up and pressed firmly on everything and made sure nothing was disconnected. It was hooked up to a surge protector all week long so I don't think there was a power surge that messed it up. Could this just be the graphics card? Would that cause all of these power problems?
I moved to a different outlet and set the computer up with the same results.
Any help would be appreciated !

I'm a newbie andknow very little about computers except how to use them. My PC (VPR Matrix 1800 - Windows XP) was running completely fine with the exception of losing time on the clock for the last couple of days and now all of the sudden I have no signal to the monitor and no pwer to the keyboard or mouse. I have switched out the monitors, keyboard and mouse and they still don't work (they work with my other PC). Also, there is no beep when powering up.

Any advice that an ameteur could handle? I have opened the case and it seems that fans are working, everything is in place and attached and it's not super dusty or anything inside.

I would appreciate any help - I know it's not always easy helping an ameteur but I would really appreciate it. I just don't have the money to spend on taking it in somewhere right now.


A:No signal on monitor, no power to keyboard or mouse...HELP!

Welcome to TechSpot

Before you start spending money, check the battery on the motherboard. Careful you don't break anything when you remove/replace it.
While you have it open, check that all the fans on the CPU and in the powersupply are working. Overheating will cause boot-refusal or worse!

Hi, I have a computer that is not to old. It is an Acer Aspire l320.
One day as i was using a program it completly froze, so i restarted.When i did it got to a loading screen just about to the screen where i pick my user account to sign on and it froze again, So i once again restarted and when i turned it back on it sounded asthough it was started up normally aka the beeps and crap it makes when it boots up all sounded normal but i noticed my keyboard and mouse didn't light up like they should and the monitor was in a sleep mode aka it is on but it's a black screen with flashing light at the bottom the same it would be if i turned my pc off but left my monitor plugged in/on.So anyway i waited and hour and it booted normally again.It went about a week or longer and i decided to leave my pc on overnight,when i got back on it in the morning i moved my mouse a little to warm it up and it froze again just like last time so i restarted it and the same thing happened but it has now been a few days and it stll isn't working.Does anyone have any suggestions to try to fix it? i really don't know much about pcs other than how to use it lmao.
Oh, other things i should note.My mouse and keyboard are both usb and they both work on other pcs same with the monitor.
Also i turned my pc on while it was like this and tried unplugging my mouse and plugging it back in and when i plugged it back in it briefly lit up like it should but went out again when fully plugged in.

Whenever I turn on my PC it boots up normally, but after it goes through the windows loading screen, my headphones make an awful screeching noise and all power to my mouse, keyboard, and monitor gets cut off and the tower keeps running. The only way to turn it off is to use the power switch on the back of the computer. And here is where it gets complicated: The second time I boot it up it works fine, but if I shut it down or put it to sleep, I have to repeat the process. That's all, really. My system specs are below:

Check all of your power connections, unplug the drive, see if it resolves. If it does, there is something wrong with the drive or your PSU/grounding.

Gateway desktop, low-end model, 2-3 yrs old, running Windows 7 with current updates.
These problems started a couple of months ago, went away for a while, then came back even worse.
A couple months ago, after the computer was on for a couple of minutes, the monitor would go black from loss of power and the sometimes the mouse and/or keyboard. The CPU would still be running. I did two things that seemed to help. The first time I did them, no problems for like a week. The second time I did them, no problems for a couple of months. What I did was: The monitor and keyboard and mouse are all USB attached, so I tried switching ports. I would also pull the power cord from the CPU, depress the power button for 10 seconds, then plug back in.
The computer is not used a lot. Just a couple times a week. But no problems for at least 3 months. But now the same problems are back and the "tricks" I used in the past are not having any effect.

If I were advised that it's almost certainly the power supply, then I'd bother to replace it.
If I were told it could be the power supply, could be the motherboard, etc., then I'm inclined to give up on the machine and replace it with another cheap desktop.

well i am new to this lark, but i decided to build a pc without knowing really what i was getting myself into

okay, so i haven't got it working as of yet, no power to keyboard or mouse, both usb, and no output to monitor. lights and fans all come on though? so that means there must be some power?

i have removed everything but the mobo, psu, cpu and screen/mouse.
also, have 2 processors and it doesn't work with either
the motherboard was sent back to the supplier to check for faults but it works fine apparently.
No video cards or anything like that.

I'm at a bit of a loss really

like i said i haven't even got it working yet!

help much appreciated

A:Newbie PC build no power to keyboard/mouse, no output to monitor

complete specs would be nice; it would give us an idea of what hardware you're using. it could be something as simple as an underpowered PSU or faulty RAM. make sure the processor is seated correctly and that the memory sticks are properly clipped into place.

I have Compaq Presario S4040SE with XP Window
Keyboard and the Mouse have PS/2 connectors

Last night the Mouse stopped functioning (arrow on the screen not responding to the Mouse movement). Follwing are stepped I took.

1- I turned off (hard turn off, couldn't use Start Menu to turn off because neither the Keyboard or Mouse were functining).

2- Turned the computer on, I heard several beeps, hear sound of fan running at high speed,
computer didn't go throught its Boot Up routine and screen remained blank.
I repeated steps 1 and 2 several times, same symptoms again: computer beeps several times, fan (microprocessor fan I think) runs at high speed, screen remains blank (no Boot Up steps displayed).

Now, when I disconnect the Keyboard and the Mouse and then turn on the computer, the copmuter goes through the Boot Up routines and display them on the screen ast it normally does.

I've read that the PSU might be broke, but I'd like to see if there is any cheaper solution first.

I moved from Norway to England and are using adapters since european sockets wont fit in England. Think I should buy a new power supply cable that fits in UK sockets instead of using adapters?

Hi there!

I recently decided to add a GPU and a new powersupply to my asus M32. I added a Radeon Rx 270x along with a 550 watt cooler master elite v2 PSU. This is my first time adding components to my pc. Unfortunately, when i had come home with a DVI cable for my gpu to monitor, the pc turned on but my screen had been blank while my keyboard and mouse emitted no light. I opened my case and saw all the fans running. Is there any way to fix this problem?

As the title says, my monitor, keyboard, and mouse won't connect on my desktop. I have tried unplugging them all, turning off the computer, removing a powersupply within the computer and readding it, and dusting off everything inside. it appears to be the computer, and not the peripherals, because i have tested and know that the keyboard and mouse work on another computer. Any help will be greatly appreciated, fore this is frustrating me greatly.The Fans are working, what would indicate the PSU working, the LEDs on the comp turning on? because they do.

A:Mouse, Keyboard, and Monitor not working, help please!

From what you are describing, you power on the computer and nothing shows on the screen, no beeps from the computer either?
If the mouse, keyboard and monitor are all in working order, then it means something is wrong with the computer itself.
The LED lights do indicate that the PSU is functional, to a degree. There is the possibility that it is not supplying the correct voltages but you would need a tester to verify.
It seems more likely that there might be a problem with the internal components.
If you know what to do, I would recommend
- re-seating the memory
- if there are multiple memory sticks, try one at a time. If there is only one, see if you can locate a compatible one to use.
- remove any unnecessary hardware like audio and modem cards
- disconnect the hard drive and optical drive
- try a different PSU

Try one at a time and then try starting the system. If you hear no beeps and see nothing on the screen, that would mean something serious has failed, like the CPU.

I left my computer on for about half an hour whilst I went downstairs to do something , when I came back I had found my monitor had turned off and the power button light for it was flashing. The computer was still on but it hadn't slept. I'm not sure of the settings I had it set to but I tried to wake it by moving the mouse and pressing the keyboard however it still didn't respond so I turned it off manually by holding the power button.

When I turned it on again , the same thing happened , the mouse and keyboard were unresponsive and the monitor light kept flashing . I thought at first it was just my mouse so I unplugged it and tried a different port , still didn't work. I tried every available port on my computer and the mouse didn't work . I tried it on another computer and the mice and keyboard worked there so I knew it was a problem with my PC.

I unplugged everything , removed the cover on my case and pretty much cleared the dust out using my air blower, turned on the comp again and the fans were running fine , GPu fan was running and so were the other fans. No beeps from the computer either. Not really sure what's going on but I really hate to say this but I think it could be a hardware problem. PC is not overclocked.

Hey all,

I built a computer with these components:

Corsair 200r case
XFX pro 550w psu
Gigabyte F2A85XM-D3H motherboard
AMD AthlonX4 750K processor
Kingston 4gb DDR3 1600 RAM
Stock heatsink
AMD Raedon 7700 graphics card

I put everything together and my monitor wasn't getting a signal and mouse/keyboard were lighting up and then off.

I took the motherboard out and examined the stand offs. I took out the centering one for micro boards and one that didn't mesh with one of the holes. I tightened everything down again and the same thing.

Next, I took the heatsink off because I noticed the processor didn't stay securely in the motherboard. I still could take it off even with the metal arm raised and lowered like it should. I matched up the triangles, as well. But I still thought it must be ok and put the heatsink on. Now, pins are bent in some places. I am now straightening them out.

I have changed the ram locations and took them out. The atx 12v is plugged in. I have put the monitor cable into the graphics card, into the dedicated slot ( with and without the graphics card in) took the peripherals out and back in, and tried the graphics card on another computer.

I have looked all over the net and haven't found a answer that I haven't tried. Are my parts incompatible or am I missing something at the install?

Thank you for any help! This computer is the stuff that makes my nightmares come true

A:New build, monitor/keyboard/mouse not working

Any BEEP or other error indications?

The monitor "not working" likely isn't a video issue. The motherboard likely isn't completing POST. Which would indicate a hardware fault. As you mentioned pins bent on the cpu, I doubt they are now straight and connected properly. There was also likely cpu or motherboard damage resulting from powering on with the cpu installed incorrectly.

Pull it all apart and bench test it. Place the motherboard on a desktop on a non-conductive material (cardboard or the foam pad/bag from the motherboard box). Install the cpu with/heatsink. Connect the power supply and attempt to power on. You should get BEEP codes for missing RAM. If not, one of those three pieces of hardware is faulty.

The only thing left from my old computer is the hard drive and disk drive. It boots up and the fans all spin but shows no signal on the monitor and has no power to my mouse or keyboard, I have reset my CMOS and pulled my battery out I have drained the power from power supply while unplugged I have tried every single thing I can find online. Could my hard drive be causing this? Is there a way to reset the hard drive and still keep the OS without being able to see it on screen?

Hello 1st post here
so right to it
I have a little problem now that I may have started when blowing out my PC with the airhose to remove the dustbunnies as I do every few months
afterward it wouldn't boot up, but did after a few tries--only the fan came on very fast & loud. Eventually it slowed to normal
within a few weeks an error box popped up and never left saying

POWER SURGE AT USB HUB PORT [a USB device has exceeeded its power limit]

I saw the couple of posts regarding this error here and a few elsewhere---and tried what I could---turning off the ports in the device manager---but turning off one left them all off and I had no interface!
I found an old direct plug-in keyboard and got going again
but still the error
trying to plug into the USB ports other than the mouse killed the CPU
unplugging and waiting I got the thing to boot after a number of tries
still the error box!
I tried to find a short in the USB slots
I tried removing and re-seating my boards
after that It wont fire up!
seems to start to---but no signal to monitor or mouse--then an alarm sounds! A long pulse from the tower itself--5 blasts and no function after repeated tries

who knows how to fix this?

help appreciated!

A:No signal to monitor following Power surge error

I had a power surge while my PC was turned on. Everything died. At first I thought nothing worked because when I pressed the On button, nothing happened at all with the PC or the monitor. I went through some forums and found that I should check the power supply. I changed the 5Amp fuse in the power supply. As soon as I did this and plugged it back in, the monitor which is powered by the PC clicked on and showed the test screen. But still, when I press the On button on the PC nothing happens at all. As you can tell from this email I have minimal expertise with PCs. Can anyone advise?

Hi, I was updating a Harmony remote yesterday and got a power surge on usb port error message, then the computer locked down. After keeping it unplugged for about 30 minutes, I tried booting it back up, it started to but hung before it got to the windows load screen. I shut down the cpu and pulled my cmos batt. After a short wait reinserted it and rebooted, went through and set everything back up and continued to windows. Once back in windows I got the power surge message again, and noticed that my printer was showing that it wasn't plugged in. I hit the reset button on the power surge button and it went away only to come back after a minute or two. So I hit the reset button again and unplugged the printer from one of the back usb ports. I turned off the printer and plugged the usb cord back in, then I powered the printer back up and it still didn't recognize it. Again the surge bubble popped up, and again I hit reset.

I had a power surge, and this caused my motherboard USB ports to stop working: there was no power being given by them. My case USB ports, however, were still working. I thought, because my PSU was quite old, I should get a new PSU, and I did. Unfortunately, this did not work. I have tried many things: unplugged the PC, and pressed the power button for 15 seconds, plug it back in and power on; updating drivers; getting a new PSU. It's really annoying that I spent my money on a PSU then it doesn't even solve the problem. I have looked around and seen it might be that my USB ports have been fried. All the other ports on my motherboard are still working though....
Should I get a USB hub, or should I try to fix it?

A:Power Surge - now my USB ports are not working

A hub won't fix dead ports, unless you intend to plug it into the remaining working ports.

I'd get an add-in USB 3.0 card instead.

You didn't give any details on your computer but if you have a modern computer with PCI-Express slots then get a USB 3.0 PCI-Express, if you have an older computer with only PCI slots then you'll need a plain PCI card. Here's some examples: http://www.newegg.com/Product/Produ...scription=usb+3.0+card&N=100160874&isNodeId=1

I'm using Dell n7110, Win 7

Recently I bought usb fan (small one, not the pad) and it worked good for few days, then I started to get this message:

Power Surge in hub port
A USB device has exceeded the power limits of it's hub port. For assistance in solving this problem, click this message.

I've read lots of posts about this but can't find the solution.
I have 3 usb ports, now only one of them works. I can't have 2 usb cables or anything plugged in at once.



A:Power surge/usb port not working

The error usually means a USB device is drawing too much power. It may or may not have already caused USB power damage. If the issue only arises when using a particular device, then that device is likely the cause and/or faulty. If it now occurs with all devices, I'd suspect the USB controller is damaged/faulty.

After a power surge on hub port when attaching a card reader to a front USB port one of my external hard drives disappeared.

The drive works fine and is now on another USB port.

The non functioning rear USB port has the following properties (image 1) and the location address looks weird compared to the functioning USB port below it (image 2):


I have tried uninstalling/reinstalling the driver and disabling/enabling, rebooting etc and it still will not work.

Any suggestions are welcome.

A:USB Port Stopped Working after Power Surge

After a power surge on hub port when attaching a card reader to a front USB port

How do you know there was a power surge at this time?

I am not sure your first screen shot is of the port, I note it says device. But I agree, the location looks bad.

I have tried uninstalling/reinstalling the driver and disabling/enabling, rebooting etc and it still will not work.

Have you totally shut "off" your computer? Not just reboot, or "shutdown", but totally off by unplugging from the wall (or setting the master power switch on the back of your PSU - IF it has the option - to off). This is the only way to totally remove all voltages, in particular the ATX Form Factor required +5Vsb standby voltage PC power supplies supply when the computer is simply shutdown (which is really standby mode).

Note there are several "Wake on..." commands set in the BIOS Setup Menu that use this +5Vsb voltage to keep various circuits and settings "alive" when the computer is in standby mode. These include Wake on Mouse and Wake on Keyboard - which obviously rely on USB. That means USB ports are still alive even when you have exited Windows and shutdown the computer.

If me, I would uninstall your device and the drivers, shutdown, then remove power from the computer for 10 - 15 seconds to ensure all standby settings are released. Then connect and boot and see if the device is detected, drivers load, an... Read more

Bought this desktop about 6 months ago. It had been working well for a few months and then a number of issues turned up. Keyboard and mouse would not response at all and monitor is off after the computer wakes up from sleep or fresh restart; wiif is disconnected and no wifi network is shown; the monitor (Dell P2715Q) would suddenly flicker constantly (one second black and a few seconds normal display). These problems can go away if I restart the computer, sometimes once, and sometimes a few times.
I can't remember if this had anything to do with BIO upgrade. My feeling is that it has no connection.
These problems are very ignoring. I shall appreciate suggestions to resolve these problems. Thank you.

MOD EDIT: moved to Win8 from Am I Infected ~~ boopme
Hello! I've an old computer I'm working on. Its a 4-5 year old desktop. It was pretty nice when it was bought. I installed windows 8 for kicks on it.
My problem is this:
I push the startup button, the machine starts up, but it doesn't show anything on the VGA monitor (it has a DVI port as well, I tried it but no luck), the USB Keyboard and Mouse do not light up.
The CD drive does come out.
My guess is its a virus, but which one?
The computer has no important information on it, so I'm ok with starting from scratch. What could the problem be?

A:Windows 8-No monitor, no usb, no ps/2 for mouse and keyboard

Is Windows 8 installed? Did it ever work? What is the make and model of the computer?

After a power surge, a Gateway DX4200-09 with an upgraded processor stopped working. Due to limited funds, i bought a Used power supply and replaced it. I also bought a refurbished motherboard stock for the computer, and put it in. The computer turns on , fans on the motherboard spin, but the monitor displays nothing. The power supply fan is NOT spinning. Is this an indicator that the Power supply is bad? Power on the motherboard panel ( USB ports and etc., ) the components will "flicker" and then not work period, unless i tamper with the wire , unplug it replug it in. then it will flicker again. CDROM pulls in and out. Wiring all done correctly. Could this also be a processor problem? I am so aggravated

ok...so i have the Microsoft Reclula keyboard and a wireless mouse....

evidently on windows 7 (vista has no troubles) the devices just stop receiving power or something.....the mouse would stop moving, the keyboard back light will turn off and stop responding......and the computer would just keep on running without me....It comes back on but sometimes it just keeps dying, making things unplayable.

any ideas as to what this is? Vista takes even more out of the computer so it couldn't be a power supply problem....wtf is happening its annoying and i cant play some of my games and programs because of it.

I asked this question once before here, only on the video boards - got nowhere then, and I've changed almost all my hardware but the video card (and reinstalled with the upgrades) since then - so I'm giving it another whirl here.

My monitor won't power off consistently. It's an ingoing issue, and has lived through more than one complete format & reinstall, and more recently a motherboard/CPU swap, and now a new monitor. I ended up with a burn in my old monitor, and would love to avoid burning into this one too.

It cropped up sometime after I switched to LCD from CRT, but I'm not sure it's related to that - it didn't happen immediately with the switch.

Neither Google searches nor searches here have turned anything up. Help, please!

My friend is having this problem where he gets the error "Power Surge in Hub Port" and his mouse stops working. Usually he is able to just take it out and put it back in and it will work for another 10-15 minutes. However, as of today, he got that error and tried several times but nothing, it's just stopped working. The stupid thing is it tells him to click on it if he wants to fix it, but his mouse isn't working, and when it does work, the message goes away. Is there anything I can do to help him out? So far, having checked out the problem, its not the mouse, unless both of the mice he has are both defective. I just can't locate the problem. Thanks in advance.

A:Unresponsive Mouse "Power Surge in Hub Port" Error

Is this USB or PS/2? In other words, is it a little round connector, or a rectangular one?

If it's round (PS/2), I'm not sure what to do, but if it's rectangular (USB), try plugging it into a different USB port. Maybe plug it into a port on the front of the case.

it works on the bios MENUS and even the mouse works on temporary Ubuntu environment which i booted from a disk...nothing seems to help......i need help Pronto!!

A:Windows 8 Keyboard and mouse not working

if the mouse stops working even when in Linux then there is a hardware issue. Try a different mouse or keyboard and see if the works any better. If not then the rig may be in error and in need of a new system board.

Rebooted my computer yesterday to find that my mouse and keyboard will not work in windows.

The keyboard does work prior to windows loading, I can use it to use F8, etc but once I am on the windows loading screen neither works any longer.
Windows will completely load fine as is all is well, all of my stuff loads, I just cannot use my mouse or keyboard.
When I reboot with no keyboard or mouse plugged in, once windows is all up and running I still see a cursor frozen in the center of the screen as though there is a mousse plugged in - it even will have moments with the little spinning wheel on the cursor as though it is waiting for something to happen.

I've tried starting up in safe mode, but neither the mouse or keyboard will work in safe mode either.
I've also tried a different keyboard (sstill USB as it is all I have) but that did not help.
I let chkdsk run to no avail, I don't know what I can do to fix this at this point.
I also tried to remote access my computer from my boyfriend's but my computer does not have remote access allowed.

The mouse and keyboard are both USB
I have a Dell Studio XPS 8000

I have my little dell windows CD that came with the computer, but I know if i reinstall windows I will lose all of my data (should have backed up, I know). I am willing to do this if U have no other option, but I would really like to avoid losing everything if possible.
