Hp pavilion dv9700t black screen with colored lines

30 seconds after windows fully boots the picture turns into a black screen with random colored lines/blocks. I have tried to boot it multiple times with the same result. Is the video out and if so does that mean that the whole motherboard will need to be replaced? The video card is 512MB NVIDIA GeForce 8600M GS. I believe this is integrated video correct? Thanks in advance for any advice you can give me.

Well the first thing I would try is to hook the computer up to an external monitor to check and see if the video controller itself is causing the problem.... If the same thing happens on the external monitor, then it's the controller hardware or the driver.... so to rule out the driver, download a different version of the driver for that card and install it. If the same thing still happens, then you should suspect the card itself, and yes, on a laptop the video card is integrated on the motherboard, so if it needs replacing, then you must swap the whole board. Hope this helps!

I have HP LaserJet Enterprise 700 color MFP M775dn ptinter and i forgot the username and password to access the setting through the web, any way to reset it please ?


You will need to perform a partial clean. Turn off the printer. Turn it on and watch to boot up on screen closely. When the black line appears under the HP logo, touch the HP logo. Display will go to a black and blue display. Use the arrows on screen to scroll down to administration, select partial clean and press ok, and then press back arrow until continue appears on screen. Press ok and unit will restart. You will lose most of your settings this way but you have no other choice.

My hp pavilion 513n has completely stopped working! I need help!


Start the computer, and keep pressing F8 until you get a "boot" menu -- white text on a black screen.
Select "safe mode with command-line", and see if Windows will start.
If it does, enter 'CHKDSK C: /F' to get Windows to check the integrity of the file-system.

Then, find a friend with a genuine Microsoft Windows XP CD-ROM. Boot from that disk, and choose "repair", and see if the boot-process can "repair" your installed copy.

Screen stays black


There is few reason. Either your one of RAM is defective. Try both memory one by one. Even though if U don't see screen than its time to change motherboard.

Black screen


If the screen is breaking up into multiple screens, the video resolution isn't set correctly. Change the video properties back to the native resolution.

Right-click on an empty area of your desktop screen. Click on Properties at the bottom. Now click on the Settings tab.
The Screen Resolution slider should be all the way to the right, close to -> More.
The Colors should be set to the highest setting.

When you close the lid, you may have your laptop set to Sleep Mode, check that. You may also have your screen saver set to Blank, and no screen saver has been chosen.

(1.Screen Saver: Right-click on empty area of desktop>Properties>Screen Saver.

2.Sleep Mode: Start>Control Panel>Performance and Maintenance>Power Options>Power Buttons>When I press the sleep button on my computer>Then choose what you want it to do)

If none of this helps, I suggest you have a problem that HP needs to repair. Since you bought this dv9700t last July, would I be correct in assuming it's still under warranty?

Hp pavilion dv9000 wont boot,coloured lines appear no bootscreen


This is caused by burn out of the Nvidia graphics chip on the motherboard. You need a new motherboard. This is due to a design flaw (the subject of a class action against HP in the USA). I have had two motherboards fail on me in this way so far - do not expect any worthwhile support from the HP "support" people they are all in India and can hardly communicate outside of their simple repetative scripts. Its impossible to escape them - I tried communicating with head office but all you get is contact details back to the incomprehensible Indian call centre. I strongly recommend against ever purchasing from HP again.
