Pavilion dv7 blue screening - HP support assistant cannot test BIOS or memory modules but BIOS can?

About a month ago my dv7 started doing something strange - during normal use (not gaming, just word processing, showing a powerpoint presentation, showing a video on youtube, etc.) the cooling fan speed would suddenly ramp up to jet-engine speed and shortly thereafter the computer would blue screen, crash dump, etc. (no, I did not write down any info from the blue screen message - I will do so next time). Having experienced a blue screen issue with a Dell laptop I thought the hard drive was going bad, because about the same time I was suddenly unable to run a backup of the hard drive. After several attempts, I was finally able to backup the hard drive, and then replaced it with a new drive, re-installed OS with my recovery flash drive, worked through all of the windows updates that were recommended, and thought everything would be good to go. Now I have no problems backing up hard drive, etc. Then on day 2, after only a few hours of use, the cooling fan speed suddenly ramped up again and the blue screen returned.
A friend who is a tech suggested running HP diagnostics on everything, so I rebooted, hit F2, and started by testing the hard drive; as expected, no problems there. I next tried to test the memory (8192 MB total in two modules), and the test failed. I also tried testing the BIOS, and that too failed. The HP diagnostics reported that it couldn't even read the BIOS. Hmmm, strange. So I re-booted, hit F10, and went into the BIOS (BIOS date 10/5/11, revision F.1B). I HAVE NOT IN ANY WAY MODIFIED THE BIOS - I'm good, but not that good. Via the BIOS test utility, I tested both memory modules independently and then together, and everything checked out fine. I also tried switching modules between slots and re-tested via the BIOS utility, and that too checked out. I then returned to the HP diagnostics utility and tried re-testing the memory (both modules together - failed, one module at a time - both failed, in both slots).
HP tech experts, can you give me any guidance? This has been a great machine for me, I have taken good care of it, and am hoping to get a few more years out of it (I'm a middle-school science teacher, can't afford another one at this point). If I can't find a fix, I may have to go back to using my antique overhead projector in my classroom...

Hi @h20roks ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv7 and getting the BSOD and shutting down. I recommend to restore the BIOS defaults with this document selecting the reloading the BIOS default settings. Not rollback.
Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that could need updating.
Hope this helps you.
Thanks.

I did a clean reinstall on my Mac Book Pro and in the process I lost my Espon print drivers. I went to th eEspon site and downloaded what was needed. I installed per instructions. I was told to reboot, but all I got was a blank blue screen. I shut down the computer again all got was a blank blue screen. What should I do> How can circumvent the usual satrtup procedure.

Upgrade 10.5.4, blue screen, tried Support suggestions - Now Stuck

I have a G5 (dual 1.8) and attempted the upgrade to 10.5.4. There wasn't enough room on my primary hd, so I pointed the install to a second installed identical drive. I got the blue screen after install. I searched support and found: http://support.apple.com/kb/TS1545
I tried A (fire wire to laptop) and couldn't find the file. I made the mistake of ejecting the OSX disk when it appeared in the Finder window (out of habit). Still the blue screen. I then tried C and all commands seemed to work. Still blue screen. I now want to try B (Archive Install), but the OSX disk is no longer in the optical drive. I don't know how to get it in and I don't know how to interrupt startup without it there. I'm a bit of a novice here, so I hope I didn't miss something obvious late at night. All help is appreciated. Thanks.

This might work. There's a little hole underneath your optical drive on the front. Hard to see. Insert a straightened paper clip into the hole and the cd/dvd tray should pop out a little bit. Grab the end of the tray and pull it out fully. Now put in your disk and when you start up the tray will close and you'll have the disk in the machine to start up from when you press and hold down "C". Might want to perform a Disk Utility check first when it starts up from the disk and then archive and install.
Good luck

HT1436 My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?

Great clue Lukas...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

HT2729 i downloaded 3 songs to my pc and sync'd my ipod and the songs do not tranfer. is this related to not having the proper itunes version vs ios? I cannot get the songs to sync, but I can move other songs to different playlists and they sync fine...

i downloaded 3 songs to my pc and sync'd my ipod and the songs do not tranfer. is this related to not having the proper itunes version vs ios? I cannot get the songs to sync, but I can move other songs to different playlists and they sync fine...any ideas what's wrong?

Hi Dennis!
I have a couple of steps for you to try in order to get those songs transferred to your iPod touch. First, make sure all of your software is updated with the latest versions. If the songs were downloaded from iTunes, you will also want to delete the songs from your library and then download them again from the list of past purchases on your iTunes account. An article about doing that can be found here:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
http://support.apple.com/kb/ht2519
If you try a sync after those two steps and are still seeing the issue, then I would like you to try syncing the iPod by setting it to manually manage. An article outlining more information on manually managing your iPod sync can be found here:
Managing content manually on iPhone, iPad, and iPod
http://support.apple.com/kb/ht1535
If you are still having issues after that, I have another article that can outline some other reasons why your songs may not transfer to your iPod, and it can be found here:
Some songs in iTunes won't copy to iPod

Wireless module change in pavilion DV7 (amd), to give support for GHz fequency

Hi
Can someone please tell me which wireless module would be best suited (compatible) to the pavilion dv7(amd) so that it might support the GHz "n" type signal. Currently it has the broadcom 4313b/g/n, which although has n in the description, does not actually support GHz! I have looked on the dv7 support manual and it lists Atheros AR9280 802.11a/b/g/n as a part used in the laptops, but I can currently locate a new one, only used from USA. I would be most grateful if someone could tell me which would be the best replacement and from where to purchase it, if possible.
Thanks

Hp pavilion DV7 blue ray problems

hello everyone
My pavilion DV7 stopped playing blue ray dvds after upgrading to windows 7. it work perfectly with all other media but when i put blue ray dvd will not recognize it or play it. in device manager i have: optical BD ROM BD-5500s ATA device.
is there a special driver for it of what may be the problem it use to work before.
thanks

Hi,
One possible cause is that there is a problem with the Blu ray laser, but I would definetely try the following to see if it resolves the issue.
Cyberlinks PowerDVD 10 is now available for HP notebooks and can be downloaded on the link below - save the installer to your downloads folder.
ftp://ftp.hp.com/pub/softpaq/sp53001-53500/sp53029.exe
When the download has completed, open windows Control Panel, open Programs and Features and uninstall HP MediaSmart DVD if you see this in the list of installed software ( if you don't have this software installed, go straight to installing Power DVD 10 ). When the uninstall has completed, restart the notebook and when Windows has fully loaded, double click the PowerDVD 10 installer to begin the installation. Again, when the installation has completed, restart the notebook and then try a Blu ray disc.

DP-K

Support Assistant cannot be uninstalled.

Support Assistant is not working correctly but when I try to uninstall it before reinstalling it, it starts off ok but then leaves a message that it cannot be uninstalled as it has not been installed. it is obviously there in Control as it is shown in the list of installed programmes.

Hi Brian,
Try the following.
Download the HPSA version on the link below and save it to your Downloads folder.
ftp://ftp.hp.com/pub/softpaq/sp58501-59000/sp58915.exe
When done, open your Downloads folder and cut the installer - now click the Start Menu, open Computer, open Local Disk C and paste the HPSA installer here.
Next, right click the HPSA installer and select 'Run as Administrator' to start the installation.
Let me know the following.
Does this install Ok and if so, does HPSA work?
If it installs Ok, but HPSA doesn't work, can you now successfully uninstall it from its entry in Programs and Features?

HP-Pavilion A6130N Blue Screen Crashes

Hi,
I've been experiencing blues screen crashes for the past month and I'm not sure what is causing them. I've updated everything and ran HP diags and it states all hardware ok.
I've uploaded my minidump, could someone analyze???

Thanks!!!

Did you burn a set of the HP Recovery Disks? It takes three DVD+Rs. Is your data backed up?
Did you check all the bios and software updates that were posted?
Try this bootable memory diagnostic CD. Download memtest86 iso file and burn it to disk using Imgburn.
Try this procedure:
Unplug the PC and open it up. Clean out all the dust. Carefully remove and replace all the cables going to the motherboard one at a time. Do the same for the memory dimms and the video and sound cards if you have any. You might want to buy a can of compressed air to blow the dust out of the CPU heat sink. Plug your PC back in and give it a go. Don not keep your PC in an enclosed space.
If after doing all the above and your PC is still crashing then use your HP Recovery Disks.

My Pavilion dv7-6175 only has 1.5GB free in my Recovery (D) drive. How can I get it clear and freed?

After Microsoft connected me with their tech assistant who did a remote assisted check on something, he told me I had corrupted files and that for $299 he could fix it. I don't know what he did, but I didn't go along with that and did a recovery to put my laptop where it was before the call. My laptop was 3 days old and I doubt it came "corrupted" from Office Max or HP. Consequently, I only have 1.5 GB free of 14.3. How can I get back the GB lost in case I ever need it again? If I click on it, a HP icon comes up and it says "do not delete or alter any of these files." I have the Pavilion dv7 6175, Windows 7 64 bit,
Intel cor i5 laptop.

You won't need the 1.5GB space on the resovery partition. Almost full is a norm with the recover partition. It is a partition that you must not save anything to as it serves only one purpose. Save to the Data or C: drive or an external disk.If you save to the partition then you will lose the F11 keystoke allowing you to access the Recovery Manager on powerup in case of an emergency.
My loaner HP dv7-4180ea has a recovery partition of 21.5GB and has 3.15 GB free.
The one thing you do need to make sure of is that backups are not saved to that partition.
Have you created Recovery media? It is wise to do that.

erico

HT1752 my powerbook g4 will not boot up. i get a blue screen. i have tried to start up in safe mode, but get the same blue screen.

My Powerbook G4 (with Snow Leopard operating system) will not boot up, I get a blue screen. I have tried to start up in safe mode by holding down shift key after startup tone, but end up with same result...blue screen. I need important photos and documents of this laptop, Even if I can just get it started up one more time. Need help fast! If you know what to do, please message back.

In the text you say you are using Snow Leopard. Snow Leopard will not operate on a G4 (or any Mac with a PowerPC processor). Leopard OS 10.5 is the max OS for PowerPC processor Macs. Your profile shows OS 10.5.6. What OS are you using (or trying to use)?

Ok so i got this laptop in a few days ago here are the problems and the things i have tried. This laptop when it came to me did not have a hard drive, so obviously no OS. Upon installing a hard drive then trying to load Yosemite from a USB stick, I turn mac on, sleep light will blink 5 times then boot, Will come to normal gray screen then apple logo, will then load the OS install, but go straight to a blue screen with vertical lines. Tried different hard drive, tried different RAM sizes and speeds, tried different OS, tried CD instead. Have done numerous PRAM and SMC resets. trying Safe mode gets me a panic cpu 4 caller error then restarts. I have tried using a hard drive that had an OS already installed and will go straight to blue screen after loading. I have tried fsck -fy in single user mode. I do get that disk2s3 is write protected in single user mode, but im pretty sure that its the OS disk. I do not see a second hard drive in single user mode but i believe that because its not partitioned yet. Any ideas community?

Tried doing OS X lion by CD now, and will only get half way through load bar before the apple logo and loading bar disappears and then it will sit at a gray screen.

Blue screen will not complete hardware test

Hi I have a 2010 mid macbook pro with a blue screen no start up tried hardware yes and it stops at 95% what the heck any ideas?

Try to put the phone in recovery mode and restore it. If that does not work, take it in to an authorized service provider or Apple store for service. It is still under warranty.

I cannot here whene someone calls me, but they can here me fine

when someone calls me, I cannot here them, but they can here me. any ideals?
