Unfortunately you have a bad graphics chip on the motherboard. You will have to take it in and have it replaced, or if you are handy you can order one and install it yourself. If you do it your self (CLICK HERE for your models service and repair manual) Follow the manual closely.

**because the graphics chip is integrated with the motherboard it can't simply be replaced, the whole motherboard needs to be replaced. Heat causes this problem with the gpu so make sure to clean out the heatsink fan when dis-assembled.

EMachines eMD620 suddenly shutdown and not boot anymore


When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

Flashing lights with no fans, held power button down & now only red lights (internet adapter, volume button) & fans are working why? help?


this sounds like a hardware or driver issue
restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

you could select the option start at last known configuration that worked this will tell you if and what file has been corrupted or missing then you will know if its a hardware issue



test all leads that attach to your hard drive including electrical extensions

the leads from your ((motherboard to your hard drive)) Sata make sure they have dust free secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?


even something as small as an electrical extension or a faulty fan lead can cause this problem a computer needs all of the data and electrical current to travel through every working device and to have an end for a computer to be able work properly

make sure your graphics card is securely seated with no dust


if you remove the graphics card to clean the socket replace it

restart the computer the found new hardware wizard should activate


or you might try


Restart your computer
during the boot process you will see on the screen a certain key to press usually the Delete or F2 to enter setup
Press and hold that key during the boot up process to enter BIOS using the arrow keys you can load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart
hope it helps

On your keyboard press and hold the power button and press the letter R.

When the Run box comes up type in devmgmt.msc

Expand the Universal Serial Bus cotnrollers
right click on every root hub and choose uninstall
after that restart the computer

Hope this helps!

Laptop has black screen on startup. what do i do to repair this.


I have a similar problem:


I have a Compaq Presario SR2010NX desktop computer. Recently, very occasionally, the computer would freeze and the screen would scramble. It almost looks like someone chopped up the picture on the screen. Then we would have to manually shut down the computer and restart. It would always work fine afterwards.

Yesterday the computer did it again. It restarted fine but when my boyfriend tried to install a new mouse the computer froze again and the screen went scrambled. Well this time it did not start back up. I tried to unplug the computer from the wall and restart but that got me to the COMPAQ screen and then the computer froze again and the word compaq was doubled all the way down the screen. We continued to try to start it in PC recovery but it would get the the program and freeze. I actually got it to run once but I couldn't see what it was doing because the screen was scrambled.

Now we have restarted it so many times that it will start up, light turns green, and stays green. The computer sounds like its starting up and it seems louder than normal. The computer doesn't do anything and the screen is black. The lights on the keyboard do not turn on but the light in the mouse does. The CD drive will light up and run as well but nothing happens after that. I can't see the cursor and the keyboard does not work.

I opened the computer up, cleaned the dust off, tried to re-install my old RAM and that did not work either. I disconnected the CD drive but that did not work. Tried to start the computer with nothing plugged in except mouse, keyboard and monitor and that did not work.
I don't know what to do! Help!

I have a constant flashing green light and computer wont detect it


First, try connecting the external drive to another computer. If the second computer fails to detect it, chances are that the housing or, the drive inside have failed. Determining this requires a basic knowledge of external drives. If however the drive is rckognized the the second computer, turn off the first computer and strt it up again (not restart). Then plug your external drive to a usb port directly (not to a hub) and, it should be detected.

Ok,was starting and then shuting itself off,now it starts, all of the lights are on,but no boot and black screen. for a HP DV6000


most commonly this is called a bios loop, this is due to the fact of a currupted bios command or a damaged cpu. to eliminate bios you must disconnect battery and cmos battery usually located where memory is, cmos battery is a small cable attached to a metal disk. unattach hard drive and restart computer. after restart shut down computer and reattach battery. again start computer without hard drive. if bios screen does not appear and same sceneario occurs then your CPU is fried. If bios screen does appear and you reinstall hard drive and get same boot error then your boot sector of hard drive is gone.

Due to black screen at boot and boot loop I would say ypur cpu is gone.
