VGA display not being detected

My Mac mini often changes the display resolution when it wakes up from sleep, and I have to use the detect display command to get the correct resolution back. I just had to restart it because of a kernel panic event, and now it doesn't detect the display. I use a Gateway LCD with a VGA connection. Any ideas on how to fix this would be most appreciated! Thank you-

Does the Gateway also have a DVI input? If so, have you considered using DVI as an alternative to VGA?

My Ipod Nano 5th generation is not being detected by Widows and Itunes. I have tried everything based on the trouble shooting tips outlined. Has anyone had this situation before? How was it resolved. My Ipod is just out of warrenty

Have done all trouble shooting tech a through Apples and still have not resolved issues on Windows and itunes not detecting my Ipod nano 5th generation device. Tried restoring the device manually using disk mode and still not being detected by the computer. Device is our of warenty as when service repair charges are $125.00 dolars more than I paid for this device. There must be some way to restore the entire device to factor settings without having to be connected to itunes and Windows. I wish I could connect but again device is not being read. I have another Ipod that is 8GB instaed of 16GB and it works fine. The sad thing about this situation is that my 9year old daughter worked hard doing delivering fliers for a long time to save her money to buy this 16 GB 5th generation Nano. Otherwise the Ipod works well but will not syncronize songs as it is not being detected. Maybe this is a result of corrupt files that got onto my daughters Ipod somehow and thus causing it not the be detwected through the USB connection thus as a result not be understoud as a working device through Windows and itunes. If anyone can help me out there including itune techs that would be well appreciated, but for now my daughter is not able to add new or delete any songs on her ipod as well pictures, and everything. Thanks

Try changing the cord. I could NOT get my computer to recognize my iPod 5th Gen until I read somewhere that different apple devices use different cords. I was inadvertently using my iPad cord and that caused my computer to not recognize my ipod.

Ipod 4g 32G not turning on, not charging (on multiple cords, both comp and wall, 4 20min), not being detected by Itunes or Windows 7 64bit OS, will not reset, tried taking it out of "DFU", NO DMG, Itunes up2date, All I'm getting is a blank black scrn

Ipod Touch 4th generation 32G not turning on, not charging.
I have used multiple cords on both computer USB and wall USB converters. I let it sit there for over 20 min with each attempt.
It is not being detected by Itunes or my Windows 7 64bit OS. I have tried all 4 of my USB ports (both USB 2.0 and 3.0), with 3 different chargers.
Holding home and power button will not reset.
Tried taking it out of "DFU" mode but Itunes won't detect it, I didn't think that would work anyway.
NO DAMAGE, I have been very careful with it, aside from a few minor scratches. (that you can't even see unless the light reflects them)
My Itunes is up to date, as is my OS.
All I'm getting is a blank black screen. It has been working fine on this computer before. I have no idea what could have happened. I'm at my wits end here.

See if you missed anything here:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My iphone 4 is not being detected by any of my computers and not charging when connected to any computer. It will, however, charge to the car or wall. The only change that I can think of is that I downloaded a podcast from itunes directly from my phone.

I've restarted both the phone and the computer, still no luck. One computer is running Vista and the other Windows 7, both have the latest Itunes Update. Anyone have a fix for this?

Hp v235r flash drive not being detected on my computer

Hi,
I am using hp v235r flash drive for more than 5 years. It's not being detected on my computer since two days. Can any one solve my problem, as there is lot of important data stored in it and hasn't been backed up recently.

Hello budda48,
Its possible the driver for the pen drive is corrupted in your computer, or the drive has met its end of life.
First, confirm that the Pen Drive is seen by other computers. Plug it in to another computer that you havent tried yet.
If it is not working on other computers, then the usb drive is corrupted and there wont be anything else we can do.
If it is working in other computers, then try these steps to troubleshoot the Pen Drive.
Confirm that the port on the computer is not bad. Choose a different port to insert the drive. Next…
Part 1: Make sure that the drive has a drive letter assigned in Disk Management.
Open Computer Management by right clicking on Computer and clicking Manage.
Click on Disk Management. Give it a moment to open the view of the drives installed.
Look for a drive that does not have an assigned drive letter and is not labeled as System Reserved.
Note: System reserved drives are reserved by Windows and will not allow you to assign a letter.
Right-click the unlabeled drive and click Change drive letter and paths…
Click Add and then click OK to select the first available drive letter.
If the Change drive letter and paths… option is not available, make sure that the drive is Online.
If the drive is Offline, right-click the disk number and click Online.
Part 2: If the drive does have a letter assigned and it still does not work, uninstall the driver.
You can safely remove any usb drivers that are not in use (hidden drivers). Devices that get plugged in later will simply reinstall its needed driver again.
Remove the pen drive from the computer if it’s attached.
Right click Computer and click on Properties. In the System window on the left side, click on Advanced System Properties.
Choose the Advanced tab and click on Environment Variables… button at the bottom.
Under System Variables, click on the New… button
Type this in the box that pops up. Variable Name: devmgr_show_nonpresent_devices and also give the Variable Value: 1
Click OK on all the open windows to close them out.
Go to Computer Management again and click on Device Manager. Go to View at the top of the window and click on Show Hidden Devices.
Click on the drop down arrow for Universal Serial Bus Controllers to open the list. Look for any USB Mass Storage Device that is hidden (greyed out) and delete it. There may be several and it’s ok to delete all those hidden USB Mass Storage Devices.
When you connect the pen drive to the computer again, give it a minute to reinstall the driver.

HT203128 My iPad is not being detected by iTunes after I updated to the latest version of iTunes. What should I do?

After updating to the new version of iTunes, my iPad 2 is not being detected when I tried to sync. Any solutions?

A few things to try. Any one or a combo mayhelp
Reset your iPad.
Hold down the sleep and home keys for about 20 seconds. Then plug it back in and see if it is seen now.
Try a different USB port
Reboot your computer
If you have a PC:
If that doesn't fix it, go into the control panel, add/remove programs. Uninstall iTunes, apple Mobile device service, apple application support.
Then redownload and reinstall iTunes. then try again.

My iPod touch 5th generation had white screened an it won't let me rest it by holding down the home button an the power button for ten seconds I've pulled it in to iTunes an its not being detected what can i do as its starting to over heat?

my iPod touch 5th generation had white screened an it won't let me rest it by holding down the home button an the power button for ten seconds I've pulled it in to iTunes an its not being detected what can i do as its starting to over heat?

If you can't get it to shut down or restart when holding down the Home and Sleep/Wake buttons and you can't get it recognized in iTunes to restore it, the iPod may have suffered a hardware failure and will need to go to Apple for service. Someone else here may have additional suggestions, though.
There is no "fifth generation" iPod touch, by the way, just for the sake of clarity; not yet, anyway.

IPhone 6 and iPod Touch 5 not being detected by iTunes 12

iPod 5 and iPhone 6 is not being detected after I downloaded iTunes 12.1.2
Tried changing the lightning conductor, that didn't help either.
Re-installed iTunes but it was of no use. :/

See iPhone, iPad, or iPod not recognized in iTunes for Windows - Apple Support
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

Iphone 4s not being detected by windows 8 laptop and itunes

Hey all,
My iphone 4s is stuck in recovery mode and my laptop is not detecting the iphone when i plug it in. I plug in my other iphone and ipods fine but this iphone 4s is not being detected so i know it is not the cables. I have uninstalled all of the apple apps and drivers from my computer including itunes and re-installed them again and still nothing. When i turn on the iphone it shows a blue itunes logo with a cable indicating for me to connect it to my laptop, but it turns off after 30 seconds which doesn't allow it to restore thus a notification shows up on itunes saying that the iphone could not be found.
I downloaded the latest version of ios, but could not install it since the iphone is not responding. so right now it is basically a paper weight.
Is there anything i can do?
thanks all....

Hello Bethany2
Try creating a different user for your computer and open iTunes to see if shows up in that newly created user. The article below will home a few more troubleshooting steps, some of which you have already tried.
