Computer Making Weird Colors on Login Screen

HP Pavilion dv7 Windows 10 Home 64-bit On login today, I was seeing some really messed up colors. But after signing in/waiting on the login screen, they seemingly disappear. Here is a video of it. So far it's only impacted the login screen and not the actual desktop.

the connects between the screen and the actual phone are dodgey so you will need to take it to a repair centre of some sort unless you can fix it yourself which will be very hard

Weird graphic before login screen and laptop is VERY slow

Hello,
So I have an Early-2011 MacBook Pro 17". Lately (past 3 months) the computer has been slower (which is normal, it's getting older) but now it is just unbearably slow and for seemingly NO reason. I have meters on the menu bar that say there is pleny of RAM left and the processor is running at 2%-6%. I can't figure out for a single reason why this is happening, but it is EXTREMELY frustrating, since only 2.5 years ago I paid 3200$ for this computer.
Now there is a weird graphic that appears RIGHT before the login screen appears. I have attached a photo. I currently own an iPhone 5, iPad 4, iMac 20" (2008), MacBook Pro 17" (early 2011), and an iPod Touch 3rd Generation. I have had problems with almost all the products, but yet have remained a die-hard Apple fan. I'm beginning to question my affinity to Apple, because I could have purchased a 17" Windows computer for MUCH less and then just replaced it this year. Instead I thought this piece of junk would last me 6 years.... This is hardly looking like it will be the case, as I can barely do anything on it as of now.
It's an early-2011 MacBook Pro 17", with a 2.2GHz Intel Core i7 processor, 8GB of 1333MHz DDR3 RAM and a 750GB Western Digital Black hard drive running at 7200RPM.

justinjsc,
I can’t explain the weird graphic, but I can offer something to try regarding the slowdown. Boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Did this make any difference?
In case the slowdown is due to a problem with your hard drive, do you make regular backups? If not, you might want to consider buying an external drive to use as a Time Machine backup destination.

Computer doesn't get past login screen with new HDD

I recently purchased a new Seagate (750GB Momentus) hard drive for my 2010 Macbook Pro. The first one didn't work well so I sent it in for a replacement, but now the replacement one is having the same issue. When I boot the computer, it doesn't get past the boot screen half the time. When it does, however, I can't get past the login screen; when I click login it flashes white and then goes back to the login screen. Disk utility claims to repair the drive each time that it is run, but always comes up with the same errors after booting. I am totally out of ideas.
Thanks in advance!

Drive Preparation
1. Boot from your Recovery HD. When the menu appears select Disk Utility and click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
To boot to the Recovery HD restart the computer. After the chime press and hold down the COMMAND and "R" keys until you see the spinning gear.

Why is my computer making weird sounds?

My computer keeps making a strange clicking sound, coming from the inside near the CD drive, or so it sounds. Why might that be?

There are three noise makers in a MBP. The HDD, as X423424X says plus the Optical Drive and the fans. Tracking sounds inside a MBP can be a little tricky. If this is happening all the time, a trip to the Genius bar at your nearest Apple store would be my recommendation.
Ciao.

My Computer is stuck on the login screen!!!!! HELP!

i help down command+v during startup to see what was going on, and i get stuck on this command:
Jan 20 20:22:27 KYII com.apple.launchd[1] (com.apple.mDNSResponder[19]): posix_spawnp("/usr/sbin/mDNSResponder", ...): No such file or directory.
My computer was working fine and i shut it down, and then this occured when trying to start it up. hoping someone can tell me whats wrong. Thanks a lot, Kevin

im getting this same error on my old PB G4!
i did a new install of 10.5, then combo update to 10.5.6 and software update, so far all worked.
then i set up sharing and some sys pref params. after shutdown i cannot restart and get the above error (in single user or verbose mode)
the HD does not show any errors with diskutility, i did a PRAM reset. i erased the HD completely, reinstalled the OS, but the same error happens: spinning wheel and mDNSResponder file not found.....
any hint is appreciated

Login screen changes resolution after a second

It' weird but my login screen on this laptop with arch always loads up at a lower resolution (larger font) then after like one second the screen refreshes into a higher res login. Didn't really know where to search for this issue, does anyone have any idea why it does that? There's also like a randomly red-purple colored T character around the top of the screen doesn't really bother me but maybe it's related somehow. Also I'm describing this in context of an alienware m15x with nvidia geforce GTX 260m
And it's being driven by the nouveau pkg xf86-video-nouveau

Yes, but not for early boot. That needs to be enabled manually. (Nothing to install, though.)

I used to have a problem with Ubuntu/Debian, where by my screen would randomly flicker for a second and random noise/garbled black and white static would appear until I played with something on screen. Then everything would settle down for a while, the resolution would remain the same though. That's never happened on Arch..
I should be clear: it happens as part of the boot process - not when the machine is up and running. It always happens at the same point when the nouveau driver is loaded. The reason it changes resolution is because it is switching to a driver which supports the graphics card properly and so I'm getting native resolution after that point but not before. I can't say it bothered or bothers me. The first time it was heart stopping because nothing, nothing was working and I felt I'd tried everything to get the graphics to be bearable but after that it was just part of the boot process and I was always quite pleased to see it because it meant that the graphics driver was loading! (I had trouble getting it to work and ended up having to blacklist stuff or something. Since this was my first install of GNU/Linux, getting it all working on non-ideal hardware was somewhat like being thrown in at the deep end, even though I used Debian. At least, so it felt at the time... People kept telling me to use the nvidia drivers and I kept explaining that I could not do so because they didn't make them for PPC!)

Mid-2010 Macbook Pro Randomly goes back to login screen?

My mid-2010 MBP will randomly log me out. I'll be on the internet or working on a paper and it will go to the blue screen that occurs when you're booting up the computer and then to my login screen, where I have to type in my username and password again. Anyone else experiencing this?

Hi e,
No, but try a Safe Boot:

Startup login screen at low resolution

-Problem: low resolution of login screen after power on.
-Additional info: If I log into the computer and log out, the login screen is back at high resolution
-Cause: I connected the mac pro via mini dvi to a low resolution beamer
Then I turned off the computer and now I'm stuck with this problem
- Helppp

Thanks for the advise. I was about to follow your instructions. Then came along another advise which seems to be less risky.
glad you fixed it but FYI resetting PRAM is NOT a risky operation. it's quite on par with just turning the computer off/on. it's an absolutely standard troubleshooting procedure which carries zero risk.
That solved the problem
However, I'm thankful for your effort in trying to help me. And I'll remember that the dvd-region setting will remain after a reset.
Thanks again

Mac Pro freezes at login screen

Mac Pro (2008, dual 2.8GHz quadcore, OS 10.6.8) is set up with
Energy Saver settings: computer sleep 1 hour, screen sleep 5 minutes
Security settings: require password immediately after sleep or screen saver begins
After the computer goes to sleep, upon hitting a key, the login screen appears. However after typing password, there was a message "checking password" and then the computer freezes. I've followed recommendations in Mac Pro Freezing: Checking Password
After the computer goes to sleep, the login screen is frozen. I cannot even enter password. After hard-rebooting it, it appears OK.
Here are the last entries in system.log:
Jan 8 15:21:59 oldmacpro com.apple.backupd[402]: Post-back up thinning complete: 4 expired backups removed
Jan 8 15:22:00 oldmacpro com.apple.backupd[402]: Backup completed successfully.
Jan 8 17:09:27 localhost DirectoryService[11]: Improper shutdown detected
Here are the last entries in kernel.log

Jan 8 17:09:27 localhost kernel[0]: npvhash=4095
Question: how can I find out what causes the computer to freeze and how can I fix it ?

I would say yes to the verbose mode and go one further and make it permanent. Coming to OSX from running Tiger on an XPF install on a beige G3 system (totally unsupported by Apple), it was ALWAYS a smart move and even in new machines running hardware they're built to, you can't lose. For the times I do have to reboot, it's good to be able to watch the startup, as you catch immediately if there's a problem with anything. It is verbose after all...
To turn the mode on, you open the Terminal, and at the prompt, type in
*sudo nvram boot-args="-v"* and hit enter. It will nag you about using the terminal (if you haven't done so before) and you enter your password, hit enter again and you're good to go. (if you want to turn it off, type in *sudo nvram boot-args=* and hit enter and your password again)

When I restart my computer instead of the gray screen that is supposed to appear before the login screen it shows a screen with a lot of letter

I upgrade my ssd for my macbook pro retina from the 256 to 480 GB but when I tunr it on or restarted the computer the gray screen that is suppost to apper dosent show insted a screen with lettler show before the login screen besides that the computer works fine.

I cannot decipher what is written on the images you have posted but they are reminiscent of what I have seen when a MBP is dealing with some totally incompatible software or perhaps in your case hardware.
How and or who installed the larger SSD and what manufacture is it. I suspect that is the problem.
Ciao.

Help needed in making a login screen

hi all,
i need to make a login screen in flash in which a user enters
a password and username and both are checked from an xml file. i
need your help in making it. could anyone redirect me to some
tutorial or if anyone can post the code here, i would really be
grateful to you. thanks,
gaurav

First you need to load the xml file that contains the list of
user names and passwords into variables using actionscript.
Use this tutorial.
http://www.actionscript.org/tutorials/intermediate/XML/index.shtml
Then compare the value entered by the user with the list of
usernames and passwords.
But be aware:
1>All the processing happens on the client machine
2>Extremely insecure if you are after a secure login.
3>and when you update the XML file it won't necessarily
take effect immediately on all the user's machines as they may be
using a cached version of it.
Ideal method is to use server side validation script using
asp, asp.net, jsp or php.

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

Both Chrome and Finder seemed to freeze, so I restarted the computer. When the restart finished, I was in recovery mode. How do I get back to my regular login screen?

It starts up and asks for a language. After English, it goes to the OS X Utilities screen. I have gone to disk utility and verified the disks. They both say they are okay. If I click repair, it comes back with an error saying "Live file system repair is not supported." I just want my computer back to normal! Please help! I am still in Mavericks if it matters.

Do you have a backup? If so, in the Recovery Partition go to Disk Utility/Erase, select Mac OS Extended (Journaled), click Option GUID, and erase the disk. Then re-install the OS. Reboot and use Setup Assistant to recover your data.

My 5s login screen is extra large, making it difficult to login, and impossible to reach the bottom of the main screen when I do

my 5s screen is stuck on extra large size, making it hard to login and impossible to reach the bottom of the main screen for phone or Internet.

Try pressing the Apple button, below the screen, 3 times in succession to toggle the screen back to normal size.

Rigards

Hello,
you can disable CD/USB with GPO settings to prevent the use from it.
And for the change from the local admin password you should consider that the CEO of the company should make clear policies so users can legally be punished if they don't work with the company rules.
You can manage lot of settings with scripts etc. BUT there is a time where the CEO is responsible about rules.
