HP Pavilion Elite e91804 experiencing lock-ups and crashing after LWSEP

1. Product name and number: HP Pavilion Elite e91804
2. Operating system: Windows 7 64 bit
3. No error message (other than blue screen)
4. My most recent change was sending my computer in for the Limited Warranty Service Enhancement Program, and receiving a new motherboard.
Before I sent my computer in for the LWSEP I was experiencing lock-ups and crashes only when I was multi-tasking (playing video games, listening to music, and having tabs open in firefox).
So I sent my computer in for the LWSEP to receive a new motherboard to fix these crashes, however after receiving my computer from them, the lock-ups and crashing have not been fixed and, in fact, have gotten worse. My computer will now lock-up and crash whenever I attempt to stream anything, be that music, video, etc. I can still occasionally play video games, assuming that I am doing nothing else, and that my computer cooperates with me (not locking up), but this only happens about 1/3 of the time.
My main confusion is that sending my computer in was supposed to fix my problem, not make it worse. Any help would be greatly appreciated.

IPhone 5 lock-ups and crashes after iOS7 upgrade

On Wednesday I upgraded to iOS 7. While I like the new look and functionality, I have experienced a couple of OS crashes/lock-ups in a way that I had to force-reboot my iPhone by holding the sleep&home buttons.
There are two situations where this happens for me: First, when the phone is locked (4-digit passcode), I swipe to unlock, then I try to type the passcode, but the device is completely locked up and doesn't accept any input. It doesn't react on the sleep and home buttons either.
The second situation is when answering a call: Phone rings, I swipe the green button to answer, then the screen goes black and the device seems completely bricked until force-rebooted.
Case 1 has happened 4 times so far since wednesday, case 2 happened three times (answering three different phone calls).
The device is an iPhone 5 64GB I bought in October 2012.
None of this ever happened to me before the upgrade to iOS 7.
Doesn anyone have the same issues? Where can I get help on this?

I have this issue as well and I did a hard reset and restore from icloud and did the same from my computer and neither of them fixed the issue. Of course I would be outside of my warranty period. My phone continues to crash at least 4 to 5 times a day. Please help us!!!

Lock ups and crashes

I've been having this problem off and on now for awhile. My pc will just lock up and a message comes up "A program caused this to happen" Then the pc will auto restart page. The thing about it is it's doing it more and more. There's got to be something I can do about it...

try this link http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c03408309&lc=en&jumpid=reg_r1002_us... most likely your pc is infected, my suggestion ...if you dont have important files on this computer you can revert it back to factory settings. Everything will be wiped out but Windows and the programs that was came with the package will be reinstalled

HP Pavilion Elite m9065uk - Pink Screen Freeze and crash

Hi,
Hopefully someone here can help me. I have a HP Pavilion m9065uk Desktop and I am having problems and I was wondering if anyone could point me in the right direction.
Over the last month or so I have been having a problem with it the PC crashing, at first it started when booting up, it would get as far as the Microsoft loading bar then just a black screen and nothing. I would reboot and it would boot up fine, but then started freezing with a pink screen, then after a few minutes either go to black screen or nothing happening at all. Sometimes it starts to restart up then fails to start and startup repair comes up but sometimes fails. I changed the power supply back in March, but I dont believe if this has anything to do with it, the supply is the same as the original.
I googled the boards and it was suggested that the nvidia graphics card might be the problem. so reinstalled the drivers and then tried updating the drivers and its still the same problem. The reason I say i suspect the graphics card is that sometimes when the problem originally began I would get an error message saying that "display driver failed and recovered".
Is this a problem with the NVIDIA GeForce 8500 GT card? There is no Integrated graphics card on the PC when a graphics card is installed.
The PC will work for a day or 2 then the same pink screen crash occurs, now all of a sudden it wont boot up, keeps going to launch startup repair, which does not work. I can boot up to safe mode only.
Hopefully someone would be able to point me in the right direction. I dont want to have to go changing the motherboard or worse still pay for a new PC.
Any help would be greatly appreciated.
Thanks, O

Hi,
Is this HP PC the same as yours? It might be the video card or a weak power supply. Try reseating the video card and see if that makes a difference. Take a can of compress air and blow out all of the dust from CPU heat sink and the fan on the video card. See if that makes a difference.
You could try removing the video card and connect the monitor using a VGA cable to the integrated video port on the back of your PC. Hopefully your monitor has a VGA port and you have a VGA cable. The integrated video adapter is Intel so you will have to update the video driver. Look here for the update.

Hello everyone..
I come here to see if anyone can help me... Ive done it all and nothing is working.
I just recently started having problems with my computer, im not sure why this happend but ill try to explain everything as best as I can.
The problem started a few days ago while I was playing SWG's. I was playing and all of a sudden my machine froze, the screen locked-up and then after about 2 min the entire system restarted. I then logged back into my windows and after a while a system froze and restarted yet again. I though it was a SWGs issue but then the computer would freeze while browsing the net and doing other tasks.
I have formated my machine, re-installed my drivers, and re-installed the hardward. Nothing has worked.

If what you are saying, and I am reading correctly:
The machine and game was working just peachy and all of a sudden the problem manifested itself?
Did you do ANYTHING to change your system prior to this happening to possibly have an effect?
the fast that you said you have re-loaded the OS and removed and re-installed the hardware with the same result tells me that there may be some sort of hardware failure and this could get difficult to troubleshoot.
First things first, try a memory testing software like memtest86 to see if you get any errors.

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

since you are running 10.6.8 did you install the combo update?
Mac OS X 10.6.8 Update Combo v1.1
It is more stable than the regular version.
You could use your original install disc and boot from the disc, run Disc Utility and do a repair disk.

Hal Harris

The best way is to post the crash log next time it crashes. That will contain specific information that will help find the problem. Logs are cryptic but there are people here who can make some sense of them.
I'm running 5.1.7 under 10.6.8 on both my iMac and MacBook Pro and it is completely stable. However I have no extensions installed. Incompatible extensions are a common source of Safari instability

DW 8 locks up and crashes when I try to do anything

DW 8 locks up and crashes when I try to do anything to a
file. This started 2 days ago.
When I open a file, and I try to merge table rows, or change

How do I fix this?

Might have to do with the time change.
There is a document on Adobe that goes over what you have to

Hi,
When I read these Threads in Yosemite I am filtered to show only the one listing Messages (the App) as the App involved.
This form of tagging a Thread no longer shows up in the current software used to run the Discussions.
Did you use the Mail and the Messages tags ?
It is difficult as many Mail help items refer to emails and "messages".
With me posting to the thread it should raise it to near the top again and maybe someone who knows about Mail will post.

ipad2 very slow and crashing after OS8 upgrade 8.1.1. I have tried to restore, using the iCloud backup (twice) and it works well for a short while then slows and crashes again. Genius bar help said older versions of OS8 never closed apps, so a restore should fix it, but it didn't, even with a repeat.

I have experienced recent system lock-ups and I am require to shut down with the power switch could this be a OS problem or software related using LION with latest updates

Whats up with the system lockups just frustrated as to why. I could be checking mail, surfing the web or using PS Elements 9. Makes no difference what I am doing it occationaly locks up and requires a cold boot (windows talk).

I don't think so, Lion with the latest updates is running fine for most of us.
Post the log for your next lockup or the previous one if you can isolate the timeframe.

Multiple Panics, Lock Ups and Freezes

My MacBook Pro running 10.8.3 has been having some random shut downs and lock ups lately, the latest of which took the internal boot drive totally offline. I was able to recover it after booting to my external recovery drive and running DiskWarrior 4 as Disk Utility simply said I needed to repair the drive before mounting it, but then said it was unrepairable after attempting to do so.
After the DiskWarrior repair, the Mac booted from it's internal drive like there was nothing wrong, but an hour or so later, I had another lock up where everything froze up and was unresponsive and then after a restart I got another hour or so before it shut itself down and then restarted itself, so I'm obviously less than thrilled with the situation.
This is the factory drive which came with the MacBook Pro when purchased new in January of this year, so I have a hard time believing the drive is physically bad, though I guess anything is possible. Another thing that has me thinking it's not the hardware is that the machine runs fine when booted to the external recovery drive and has no errors or any of the symptoms I've been experiencing.
Anyway, I've been looking at the panic reports, but I'm honestly not well versed in what any of this means, so I'm hoping one of the experts can chime in and maybe point me in the right direction as I'm running out of ideas :/

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to bypass Apple's oversight, or the oversight could fail in a particular case due to human error.
For most purposes, applications recognized by Gatekeeper as signed, including App Store products, can be considered safe. Note, however, that at least one trojan for iOS (not for OS X) was briefly distributed by a developer in Russia through the iTunes App Store. That store is under the same oversight by Apple as the Mac App Store, so the protection shouldn't be considered absolute. App Store products may prompt for access to private data, such as your contacts. Think before granting that access. OS X security is based on user input. Never click anything reflexively.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. Beyond XProtect, Gatekeeper, and MRT, there’s no evidence of any benefit from other automated protection against malware. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications should not be trusted if they do something unexpected, such as asking for permission to access your contacts or your location for no apparent reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
9. The greatest harm done by security software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but if they get a false sense of security from it, they may feel free to do things that expose them to higher risk. Nothing can lessen the need for safe computing practices.
10. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.

Lock ups and sound looping!

I remember reading something here about people having trouble with their systems locking up and then getting a loud static noise then a sound loop when playing games.
I am getting this about 2-3 times a night now and it is driving me nuts, I do not have temp problems of any sort and I have all of the latest drivers for everything on my system.
Any ideas?
Specs in sig

Set your PCI/AGP Freq to 66.66/33.33MHz.
Increase your DDR Voltage to 2.7~2.8v.
Check if you have any background programs causing all high CPU load times while gaming.

Lock ups and Freezing solved on my Audig

After days of trying different stuff to resolve this problem where screen locks up and looping squealing plagued my computer, I think I have finally resolved the problem. It appears that one of the programs running in my system tray was the culprit. I shut down everything in my system tray and then tried BF2 and it finally worked and has been working consistently. I do not know yet which program was causing the problem ( I'm still working on finding which one), but I have weeded out my antivirus (AVG free), my firewall?(Zonealarm),? Musicmatch Jukebox ( which I really suspected, but does not appear to be the one) and ?my Logitech wireless mouse software. Still got to reactivate Quicktime, Corecenter ( an MSI overclocking tool) Nastromo loadout manager, Instant Messenger and a couple of others. What ever the conflict in the program that is causing the problem is directly conflicting with my Audigy 2 card. I could remove the card and the problem would go away using onboard sound. But I was very disturbed that my Audigy 2 was not working. I tried removing ram, I tried using different pci slots, and lets not count the number of times that I removed and reinstalled drivers and software. Though I well give a little credit to finding the problem to this forum. There is a post advising to go to msconfig and disabling a bunch of the start up programs while doing driver removal and reinstall. After reinstalling last driver I went ahead and ran BF2 before restarting computer ( while all programs in systray were off ) and it ran flawlessly. Then I restarted computer all my normal background software loaded up. I fired up BF2 and bam there was the same old lockup and squeal. So I just went to the system tray and shut down everything and it runs smooth as butter. Hope this helps I know from reading the forums there are alot other people having the same problem.

I would be concerned that you may have a power supply going bad. Unfortunately the only way to test this theory is to replace it. If you do replace it may sure you get one that is rated at a high enough wattage to supply your system. I use a 500 watt power supply. I have had power supplies to go bad on me in the past. Sometimes the power supplies will not go entirely out, they just stop producing as much power as they normally would. This can cause some weird things to happen in your system. I've had one go bad and it was providing enough juice to let my computer cut on, but the video card wasn't getting enough?juice to operate thus I was getting a blank screen. I would also like to know if you are overclocking. Sometimes overclocking can cause heat issues that could cause a similar problem to what you are having.
