The point is, someone in the forums already did. All the forum regulars should remember when it happened too. A guy chastized us because we ask about the specs on people's power supplies. He took every post in the VGA forum to date and catagorized the solutions and found that only 50% of the problems in the forums were Power Supply Related. To me, if one out of every two problems in the VGA Forums is Power Supply Related, by asking the question, we can identify and solve 50% of the problems.
But we are used to people like yourself coming along every few months. Are you sure you did not used to log into these forums under the username of elzie?
Is this one of your old Threads:
A must read for everyone....
Richard
Yes, he does sound a bit like me doesn't he? (or vice versa). But no, we are two different people which your moderators can prove by looking at the IP addresses of both myself and elzie.
But I must admit he echo's my views. There is a definite danger that some posters who are here to help people will latch on to one supposed "solution" i.e. the PSU which is then tailored to fit all problems. Same goes for avoiding flashing the VGA BIOS especially over the Internet.
But as I've said before, 98% of system problems are software related and hardware only plays a minor role. It's a bit like a car. Without gas, you're not going anywhere regardless of all the technology that's been pumped into it. But gas can get contaminated with grit and can clog up fuel lines. So what should we do then? Change the whole car maybe? Or just replace the carburetor? After all, we don't want to risk damaging the machine by cleaning it do we?
There's just too much emphasis these days on blaming the product as the cause of the problem and replacing parts rather than taking the view that it's the user who has caused the problem himself by not following instructions when installing software. Statistics can be adapted to suit the issue too. But as I've already said, if the PSU was the main cause of failure of high end cards, the Internet would be literally littered with news about it. But there aren't any such articles, so how do you explain that?? And as Toms Hardware.com mentions here, the CPU and high end card can draw 160 watts. So it stands to reason that if you've got a 300W PSU, you've got more than enough over to run both doesn't it??
It's all very convenient to say, "replace the PSU and your troubles will be over", but if the problem persists after doing that, it won't do MSI reputation any good and the only benefit will be that a PSU manufacturer will have made a little extra profit this year.

Why wont my macbook boot after installing yosemite 10.10.3 ?

After installing the latest version of yosemite (10.10.3) my macbook will not boot. It will start to boot then show this command prompt http://imgur.com/YNb3w5W.

Windows 7 wont boot after install of boot camp drivers

I have been trying to get boot camp on imac mid 2010 with Maverick. TodayI used
Boot Camp Support Software 5.1.5621
The first set of drivers
Boot Camp Support Software 5.0.5033
kept crashing on windows. Today I noticed a new set of drivers, well its the same issue. If I leave off the boot camp drivers windows is fine, except no sound and other driver missing issues but it works. The problem seems to be Mav or the drivers, before updating to Mav everything was fine. Sometimes I can even get to the windows log on screen, at one point I was able to log on and do things. So being smart, I restarted and the problem came back. Who says Macs dont have issues.
Any thoughts

Just ran into this same issue.
My problem got resolved after using the x64 version DVD of Win7 (just x64 instead of the DVD that had both x86 and x64 versions).
What I did:
My host is Windows 8.1
After installing Windows 7 x64 as VM on my 8.1 based laptop two days ago, I wanted to do the same on my desktop PC, but I had the same issue described here.
I used a DVD just with the x64 version for my laptop and a DVD with both x86 and x64 version for my desktop.
Tried repairing as advised by a post, but got the error: "This version of System Recovery Options is not compatible
with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of windows."
I exported and imported the VM from my laptop to my desktop to test it and it ran with no problems.
So I tried the DVD that had just the x64 version of Win7 and that installed without issues.
I'm curious if this happens only when a DVD with more than one Win7 versions is used.

Osx wont boot after installing windows dev preview.

Hi. I recently added boot camp and windows 8 to my 2011 mbp 17". Ever since the install my computer wont boot osx unless i run disk utility and repair my mac partition. Then everything runs fine untill i go into windows again and then go back to osx. Thoughts?

mcwilliamsc wrote:
Do i need to make a clone or will my time machine backup work.
TimeMachine drives are not "hold the option key bootable" like a clone and with Lion there is only a "hold Command r" Recovery Partition on the same drive your trying to repair.
So to get a external source to boot Lion, you need to Carbon Copy Cloner Lion to a another new/blank Disk Utility HFS+ Journaled formatted drive. Disconnect your TimeMachine drive before doing anything and don't clone to it or everything will be erased, use another drive.
Once you have Lion cloned, hold option and boot from the Lion clone and test it out.
mcwilliamsc wrote:
I only have one external drive andni dont think a clone will fit.
Only clone to another drive with no data on it, don't clone to a partition, don't clone to a TimeMachine drive. Disconnect all other drives before cloning so you don't make a mistake.
mcwilliamsc wrote:
Also when you say c boot do you mean using a lion install disk as opposed to the install option when you boot into disk utility?
Your signature says you have 10.6.8, obviously there are no install disks for 10.7, however you can make some by "hold option" and clicking on Purchases in the MacAppStore and redownloading the Lion installer (but don't install)
Follow these directions to make multiple "hold c" bootable DVD copies of the Lion installer.
http://eggfreckles.net/notes/burning-a-lion-boot-disc/
Test the disks out, you can see it's just like the 10.6.8 installer disk with Disk Utility and everything.
With a Lion DVD one can install Lion AND the Lion Recvoery Partition on a new or totally erased drive, like we are about to do.
When you clone Lion, it only clones the Lion OS X partition, not the Lion Recovery Partition. So by totally erasing the entire disk and installing Lion from the DVD can the Lion Rececovery Partition and Lion OS X partition be restored and your GPT repaired and your firmware flushed.
So once you got a Lion clone disconnect it, then c boot from the DVD and erase your ENTIRE Lion internal drive, this means you have to select the drive makers name on the left, HFS+ journaled of course.
Once that is competed, install Lion fresh, this will create both the Lion OX partition and the Lion Recovery Partition.
When that is finished, don't bother booting into the fresh Lion install, simply option boot off the Lion clone and reverse clone onto the Lion OS X partition, this will place back Lion, all your programs and files just like before.
Then you should be back to normal, your GTP is fixed, EFI is fixed (reboot twice) and you have everything except the Windows bootcamp partition.

Macbook pro not booting after installing yosemite

I have just installed Yosemite and it now won't boot up. I just have a circle with a line through it on my screen. No idea how to resolve this! Any suggestions please.

Hi veerta,
If you're having issue with booting, the following article covers most of the general boot issue troubleshooting:
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
http://support.apple.com/kb/ts1417
You may also want to see if OS X is showing as a bootable volume in Startup Manager, as outlined in this article:

PC wont boot after installing c

Hi?I tried installing my new X-Fi XtremeMusic card but whenever I try turning the computer on, the computer wont boot up, or even reach POST. The monitor doesnt even power on. As soon as I remove the card and try turning it back on, it all boots up just fine. I have tried installing to different PCI slots with the same results. Whats the problem?

That seems to be a known issue that have been for a lot of time around with some combinations of X-Fi, mobo, and GPU...
This problem doesnt have any real solution at all... if you dont have a way to config in the bios the priority of video card, like what goes first for video PCI or PCI-E, that is the only way to fix it so far.

PC wont boot after installing nforce driver on MSI K8N Neo Platinum

After installing the nforce driver my system won't boot again. If i use safe mode it stops at the file mup.sys . Does anybody know anything about this?

Can you provide a signature with all of your hardware information like my signature (see below). Include drives and locations. Better chance you'll get help that way

3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.

After installing yosemite stuck on login screen

So against my better judgement, I decided to upgrade to Yosemite. The login seemed to be going ok, then I noticed it was stock on the progress bar... once again, against my better judgement, I did a hard reboot. When my iMac rebooted, it went through the loading screen ok, and onto my user login screen. After selecting my account and putting in my PW, it is now stuck on the color wheel loading icon... nothing happens. What are my options?

Hi there,
They DID solve it at the genius bar!
He tried a few code tricks, aka booting up using command+S, but those didn't work. He ran a restore permissions and reinstalled Lion (without removing any of my personal data) and hey presto, it works. I'm typing to you now on the machine.
Is that enough info for you, or would you like me to get more..? I do have to go back soon for another issue. I just want to help the community with problems.

Please help! emac wont boot after installing os 9 alongside os x!

Hi,
I am a teacher. My school recently gave me an emac to use in my classroom that has Tiger installed on it. I have a bunch of OS 9 games that I want the kids to be able to use, so I decided to try to install OS 9 alongside os x. I just installed OS 9 on the same partition as os x using an OS 9 emac installation disc. I had to install OS 9 on the same partition as OS X because I am not allowed to repartition the school computer. I tested out classic in OS X, but it didn't play the games well. I then tried to boot naively into os 9 by going into system preferences, then to startup, and then selected OS 9 as what to boot into. When I restarted, the only thing I was left with was a floppy disk with a flashing question mark inside. I tried to boot back into OS X by holding the option key, but my only option for booting is OS 9. I then tried to boot back into OS X by holding down the "x" key, but it still tries to boot into OS 9. Could someone please help?
Thanks!!

Hi, Stacy -
Since the machine boots to the OS 9 Install CD, it is indeed OS 9 bootable, by definition.
Since the installer on the CD was able to 'see' the destination drive, then that drive does have OS 9 drivers on it.
Those two are the primary causes for a machine not being able to use OS 9 as a boot OS.
I assume you accepted the default install of OS 9 and did not customize it. If that is the case, then it should have installed all files needed by your machine in order to use it as a bootable OS.
About all that is left is make sure that the OS 9 System Folder has been blessed - registered as a bootable OS. To do that, boot to the OS 9 Install CD but do not run the installer. Instead, open the icon for the hard drive (if it is not already open), locate and open the System Folder (not the folder named just System - that's OSX). Drag the files named Finder and System (both are loose in the System Folder's window) out to the desktop. Close the Syatem Folder. Then drop those two files back into the closed System Folder.
Once that is done the System Folder should be displaying a miniture glyph of the Mac OS logo superimposed on the icon for that folder.
One other question, re the CD you used for the installation. Was it a Software Install CD specific to that machine (does it show eMac on the label)? Or was it a retail OS 9 Install CD (white label, gold 9)?

Mac wont boot after update

I ran the latest combo update for OX X Lion. After it restart the mac no longer boots. What gives? What kind of update hoses my machine? Is there a fix? How do I roll back the update?
This is very fustrating. Please produce better software.
Thanks,
Carlos

go ahead and ddo a force quit - hold the power button for about 10 seconds. Then release it and press as normal to restart. you didnt mention seeing any installing screens so the file was downloaded but the installation didn't start so probably when you restart the installation will commence. If it doesn't, open the App Store program again and switch to the updates tab. You'll either see the restart button (which hopefully will work this time) or have to download it again.

Pc wont boot after installing new gpu (Gigabyte GTX 770 2gb)

Hi , I just bought a gigabyte gtx 770 2gb and my pc is stuck in the bios screen and beep every 10 sec , i think the bios version or the pcie isnt recent enough ,
Specs: HP - pavillion h8-1040

Intel core i7-2600 3.40ghz
10go of ram DDR3
650w PSU
If its my motherboard what motherboard will u recomanded me to instal that will fit my case , GPU , ram and processor

This question was solved.

I have the same mobo as you. What version number are you on bios wise? I have 7.12 As for your friend. HP does do frequent hardware revisions. Especially with their mobo's. So, he could essentially have a different version than both of us. Try to grab some info if you can using CPUZ and post results for mobo. Here are mine. Pay close attention to the model # and compare his with yours. Another thought. Depending on gpu brand and the bios they use. They might be more legacy bios friendly along with full UEFI support as well.
Some might only support full UEFI. Let me give you an example. I have a EVGA Superclocked GTX 660. They released a bios update for the card to support full UEFI. I flashed it and guess what? My PC would not boot up any more. Not compatible with the newer video bios. Thankfully before flashing. Since I had a bad feeling about it. I backed up my previous original bios and was able to restore them using another pc. Then putting it back in my pc. Booted up fine and works perfect again.
I am also curious. What might be the exact GTX 780 your friend is running? Brand and model wise.
