My problems started with a pop-up "hpzsetup.exe" This thing would pop up whenever I started or closed a program as well as plugging or unplugging from the usb.

I contact hp by email and they said the pop-up was from them but I should:

#1 Reinstall Usb Drivers
#2 Reinstall Chipset Drivers
#3 BIOS Update

As I finished #3 my computer went into Matrix mode. Green vertical lines then mixed with red occasionally. I have to shut down and when I start back up I have 8 little working versions of my desktop.

I contact hp by phone and the tech say I should :

restart > F11 > Microsoft system restore to a date when life was great and no computer problems, so I did. My computer worked great again, the birds where singing and the sun was warm on my face, life was good. I shut down my PC and all was good.

Next day (today): Start up the PC and within 5 minutes it was Matrix time again > BAM! > Right back into the 8 small desktop on my screen. Well atleast I know how to fix it now with out hours of wonderful conversation between someone from Mississippi trying to talk to some one from India. So I restore the same way I did before and my computer works normal for about 5 more minutes and directly back into Matrix>8 Desktop time.

What is going on? I have searched and found nothing of the sort on the web. Help!

HP dv2500
Vista Home Premium
Nvidia 8400?
120 GB
Intel Centrino DuoSo you updated the BIOS?

Do you know what version you had and what version you updated it to?

Did you use the correct update to FLASH the BIOS? (did you look for your computer model number in HP's site?)here is the link for the BIOS updated provided by hp in the email:
ftp://ftp.hp.com/pub/softpaq/sp41501-42000/sp41959.exe


Update: I TOOK my computer over to my father-in-laws to show him the problem and my computer worked fine all day. But, now my problem is back. I took some pictures of the process.




Wow.

Look through your BIOS and make sure everything checks out, specifically anything regarding your Screen or Video Adapter.

However, I strongly suggest flashing your BIOS with your original version, getting rid of this update.Replicated or offset multiple images
Multiple images on the screen horizontally or vertically indicate that the scan rate is way off (by a factor equal to the number of complete pictures.) This could be a fault in the monitor or you could be running way outside of the monitor's specifications. Even slightly exceeding these for the horizontal or vertical may confuse the scan rate selection logic and result in the monitor setting itself with incorrect scan rate settings.
A situation where successive sweeps alternate position slightly resulting in double or triple images may be caused by a incorrect or out of range video timing, a bad component, or improper SYNC signals.

Found the above info at this website:


http://www.repairfaq.org/sam/monfaq.htm#monhodegI cannot tell from the pics- is this an LCD or CRT monitor? DERR. Centrino means laptop and laptop implies LCD.


can you try another monitor[/s] can you try an external monitor (assuming there is a VGA or DVI plug on the laptop).

since this occured when performing a BIOS update, that is our first clue. Although it will be DIFFICULT you will need to try to get the BIOS version back down- or perhaps try reinstalling your Video card drivers.

Also as karnac said the laptop could now be driving it's LCD using clock settings that are too high- the best way to check this would be to enter the Display properties and try lower resolutions.

Right on BC....

My handy dandy video failure flowchart says the problem is a resolution mismatch between the monitor and the video driver....Try selecting a different resolution for the screen.how would I go about changing back to the old BIOS version?Quote from: satisfied on April 07, 2009, 01:22:20 PM
