1) Removed graphics card? Sounds like this is an NEC desktop computer, not laptop. 2) Loud pop? Have a look at this Vai,

http://capacitorlab.com/visible-failures/index.htm

See if one exploded.

(Those are Radial Aluminum Electrolytic Capacitors. They do pop. What REALLY makes a loud bang, is if a Solid Polymer Capacitor pops! Explode like a small grenade inside your computer case!

May not even see it anymore. Just a place on the motherboard where it was, and shrapnel from it all over inside the computer case.
When THEY pop, you KNOW it! )

SOURCE: Collapse in graphical view and hang!

You say you replaced the graphics card?
Either way, this is one of two things. Hardware (a faulty display card) or drivers. If it is an old card, or you did a driver update recently, go to your device manager, and roll back to your previous drivers. if this doesn't solve the problem I recommend getting the latest drivers for your display card, installing them and seeing what happens.

Hope this solves your problem!

SOURCE: After a while the screen goes grey and the computer wont respond.

it should be problem of graphics card or the graphics chip. if that is from nvidia, setting up ntune may cause such problem or if you did any overclocking. may also have a problem of getting hot. try reinstalling operating system if you feel comfortable of reinstalling OS. it would solve any driver related issue.

Then check the cooling system of your laptop.

finally think about a change if none works.

SOURCE: I have HP pavilion DV6500 laptop. Last night,

Please do not panic....The first thing what we need to do is perform a hard reset...What does Hard Reset mean... Unplug the A/C Adapter Pin from the notebook...Turn the notebook upside down and then remove the battery from the notebook...Turn the notebook in the upright position and then press the power button for 30 seconds without the battery and without the A/C Adapter Pin connected to the notebook... After 30 seconds place the battery in the battery outlet and connect the A/C Adapter pin and restart the notebook...Check if you can see anything on the screen....If you can't see anything on the screen then please perform a forced shutdown by pressing the power button down until all the lights have turned off...Then as soon as you restart the notebook press the F10 key continously on the keyboard...It will take you to the BIOS Screen... Check if you see the screen...If the screen is still blank then don't perform the next step....Click N for No...Then press the F9 key and then select Y as in Yes...again press the F10 Key then press Y and it will boot to the desktop.... still you have the same problem then perform a recovery....If the screen is blank in the BIOS Menu then try connecting an External Monitor...If you cannot see anything on the screen it is a problem with your video card or monitor you will have to contact HP since your fan does not work...If you have any other queries please don't hesitate to contact me and i will help you with the same.....

SOURCE: I have an HP Pavilion dv9000 laptop, and when i

I too have a dv9000 and the same thing happened to me 1.5 years ago. I had lights but no screen or desktop. The laptop was still under warranty so I sent it back to HP and they replaced the processor at no charge. I believe that they are also replacing parts for out of warranty as well. Also the DV9000, DV6000, DV2000 and the Compaq V2000 have been recalled for problems with the motherboard. The link below is for the recall. Hope this helps. David.

SOURCE: Dell Inspiron E1705: Getting lines/blocks of color on monitor

From a power off state, press the Fn key and the power button, this will run the BIST which is a diagnostic on the LCD, if you get screens of solid colors.
From what you describe, I'd suspect the video card which could be the motherboard or memory, try the memory modules one at a time, see if the issue only occurs with one module

My laptop is not poducing sound .....how can i download from NEC site online?


First you need to know why it is not producing sound.
Is the volume turned off (muted)?
Did it work and suddenly stop?
When you go into the control panel under sounds, does it say that you have no sound drivers? Were they ever there?
You might find driver downloads at this site:

1992 Dodge Ram 50: Horn honks all by itself.


Check the horn actuating contact at the centre of the steering wheel. It may be damaged or mis-aligned.
Also check the carbon contact that runs on the slip ring under the steering wheel (associated with steering wheel horn actuate switch) It may be damaged or mis-aligned.

If none of the above are faulty, you should look for a possible intermittent short to ground on the horn actuation control wiring.

What did you use to clean the registry? Some registry cleaning programs have a backup file to restore what was "cleaned". If you have the backup, try restoring from the program. A system restore in Windows might also repair the damage. Good luck!

Possibly an overheating problem...


Very rarely motherboard can cause burn to RAM unless most likely the RMA quality itself had the relibility issue... change the RAM unless the burn is very severe.. you may need to change the DIMM connectors (if you have the right tools) like HOt air machine..

CD/DVD won't eject, won't play, Device Manager doesn't recognize.


If it's only 8 months old, then you have atleast 4 months left on your warranty. The problem will either be the ide controller channel or the dvd drive and firmware has faulted, the same fault probably happens when you have put a dvd in and it wont read or eject. Return to the place of purchase, where the drive should be replaced or the notebook exchanged.

NEC DVD-RW 16x DL


If you switched to a different brand of DVD's try using the brand you used before. DVD burners are tested with certain brands of DVD's and sometimes the brands that aren't on that list don't work.
