Question about PC Laptops

5 Answers

Bad startup display, death upon sleeping, app opening trouble and scroll-display problems.

Hi there, anybody who can help me at all, please - it seems the HP tech support staff that I'd been assigned to are all complete idiots - they persistently ask me to "update the graphics and BIOS drivers" and it is NOT WORKING every time they ask me to do it - everytime I tell them the same result- and the last time was the 3rd time they've asked me to update the same friggin drivers again.

Anyhow, my problem is (and they all appeared simultaneously- so I believe they are all symptoms of the same problem):

- On switching on my laptop, a dim grey screen appears as opposed to the HP logo.
- Grey screen persists until Vista loads up to the logon screen (even the vista loading screen does not appear until I get to my logon screen)
- When logged in, vista works, but: when scrolling inside windows, the images of the objects in the window appear stuck, I need to click out of the window and click back in to get a 'refreshed' view of the window to show what I've scrolled to.
- Same happens when I move a window - I get what looks like a blank imprint of where the window was before, and need to minimise and restore that window to see where I put it.
- When opening various apps, the screen freezes up, then blacks out (as if it turned off), and comes back on 20-30 seconds later and an error message pops up, something like: "nvlddmkm has stopped responding and has recovered".
- My laptop does not wake up from sleep, it kinda stays that way unless I force shut down and reboot again.

On 3 rare occasions (after this problem started), my laptop booted up properly and functioned nicely for 30 minutes to an hour until it decided to get ill again. I'm relatively convinced this is a hardware issue, and may have something to do with the memory... but what could I possibly do to fix this?

Please help... my laptop suffers, and as a result I do too :(

Many thanks in advance.

    My laptop is an HP Pavilion DV9205TX- as far as I know, the specs relevant to this problem is my video card NVidia Geforce Go 7600, and the 2Gb of ram its got. If anyone else would like to help, and wants more information, I can dig some more up out of my laptop.

    Dageezer, the dedicated video ram my laptop is 256Mb, however- I believe my system has an extra 256Mb allocated to it from the RAM (or wherever it takes it from), so it's 512Mb altogether.

    And once again- I just want to re-iterate for anyone advising me to update my drivers. I have done that enough times to know that it has virtually nothing to do with my drivers. If I can find it in my HP Help utility or F1 Help, don't tell me, because I've already been there.

    And yes- doing a complete system restore or resetting it back to factory settings is included in the F1 Help/HP Help Utility. I will not do that until it is absolutely necessary.

    Regardless, thanks for trying all the same! I appreciate the level of response I get here.

    I am getting the same errors...

    (nvlddmkm) Stopped Responding and Has Recovered.... in Vista 32bit using Geforce Go 7600 on an HP pavilion dv9000 series. The computer worked fine for 1 1/2 years with the same drivers while playing WoW.. then it started a week ago lagging during play and the image would distort.. the problem progressively became worse and I now the black screen and then the error occurs while just normal Windows navigation. I have tried the latest drivers from nVidia and laptopvideo2go both caused BSOD and I have to in one instance run Windows restore and I could not see anything on the laptop so I had to attach it to my Big Fat LCD TV to troubleshoot. I have tried several other ideas I have found on the internet with no success… added a DWORD to REG in graphics folder... ran diagnostics... changes power settings... blah blah blah..

    Anyone ever fixed this?

    Hi all,

    I have the same problem. My laptop is HP pavillion DV9505tx. I was working fine in the past 1.5 years.

    My laptop was halted when I play Warcraft 3 (not World of Warcraft). Then I could not restart my laptop again. It just show grey screen, no any basic info. of BIOS and Power On Seft Test. Of course can't see anything from Windows at all. I left my computer un-touched for the whole night, and the problem gone the next day. I took the chance to do find the cause of that problem on the Internet, and find out it may be the Nvidia firmware problem or BIOS problem.

    I then update my BIOS to latest version on HP site (for my laptop model). Download NVidia driver from it website, however I can not install, it said could not locate and compatible devide for the driver (strange, even my card is supported, according to the description of te driver on NVidia website).

    Then I gave up installing new Video driver, restart my laptop, and the problem appear again, this time it never go away. I can see anthing on my screen, but I guess it boot up correctly (I tried boot from Hiren Boot CD, and see that it made sound that seem like to do correct booting routine, cause the CD has 2 option, boot from HDD or from CD).

    I can not connect my laptop with my LCD TV (no signal).

    I believe it must be a problem with video card.

I've had the same problem, operating system vista HP Pavillion dv9399ea Geforce GO 7600.
I also have a grey screen no load up. But then vista appears.

Did you get yours fixed in the end?

I've been getting the same exact problem on my HP Pavillion notebook with Vista, 2 Gb of RAM and a Geforce Go 7600.
I still haven't fixed mine, but I know this has to be a hardware problem because the grey screen appears BEFORE vista (and all it's video drivers) loads.
A notebook with no OS at all, and no video drivers installed, should still display some basic information on the screen (BIOS, logo).
In this case you just get a grey screen!

Is your laptop using a Nvidia graphic card and your Operating System is a Windows Vista? The nvlddmkm is a system file of your graphic card, the reason why HP support advised you to update the drivers is most likely because of that. However for some reasons, your operating system is unable to load properly the system file for your graphic card.
We cannot say it is a hardware issue already since as you stated it worked for 30 minutes to an hour.
As of now there are a lot of options that you may want to try.

1. Go to your device manager and try to update automatically the graphic card driver of yours from there. (The OS of yours is unable to work properly with the system file of your computer that is why you may want to try this trick)

2. System Restore via Start Menu\Programs\Accessories\System Tools
If you remember when this started to happen, like was there an automatic update from your operating system or so. You can go back through system restore before that update was installed.

3. This would be a lot of work but of course will definitely fix this issue. Back up your files then reinstall the operating system of your laptop (clean and what I mean is format the hard drive and reinstall the os). Your computer manufacturer should have thought of that.

You didn't mention the model of the system in this post but here is some information I can give you that is not system specific.

The nvlddmkm error referres to NVidia display drivers. Depending on the design of your system, the NVidia display adapter may or may not use some system RAM for video imaging. If your system has 2 RAM modules, try taking one out and see if the system functions better. If no change, try the other module.

If swapping RAM has no effect then the issue is the video card itself. NVidia video cards have either 50 or 100% dedicated video RAM (If it is listed as having HYPERMEMORY then it is usually 50% shared) and the dedicated RAM appears to be failing, hence the "Artifacting" you are encountering.

Depending on the system design, the video card is either soldered to the motherboard or a seperate part that attaches to the motherboard.

Your video card appears to have failing VRAM and needs a video card replacement. If the system has on-board diagnostics and you can run them (Often listed on the F12 menu) you may get a diagnostic failure that will prompt HP for action.

If you can't, or they pass (Passing a diagnostic does not mean the item is good, just the test found no error, big difference) the next time you talk to HP, the conversation should start with:

"I'm running the latest BIOS and latest HP Video driver and I'm still getting artifacting on my screen. .... " Describe the swapping of ram if done, and diagnostic failure and insist on a replacement video card.

I have an old comp and my is working good.
Thanks for updating each time and to cleaning all systems each day.
Try clean your Disk with clean up disk utility
you should go on all programs, find- accessories,disk clean up,
after you done that,do the disk de-fragment and clear all programs what you not using at all( be carefully with that) to don't clean something useful.
after you done all that try reinstall the vista or reset on factory settings by going in bios screen (it appears when you switching on before log in-in and see what you have a disable.Click on that to enabled and boot up again.
Good luck!

Problems with resuming windows when i close the lid!!!!!

Your Power management is corrupted. It is part of windows. Here is the procedure to fix it, from HP.
It involves setting a key in the registry. You'll need to find a tech and let him follow the instructions to correct the issue. It should be simple for the tech.

My "CD-ROM" is missing from "MY COMPUTER"

Actually, the tech was right. It is not uncommon for optical drives to go out just like that. Since you've tried the steps listed above and your computer still cannot see your optical drive, then the drive must be replaced.
