Equium P300-16 t BSOD and black screen after the removal of GPU

I have a Toshiba Equium P300-16 t and I was getting 90 c - 95B on realtemp so I bought a thermal paste of isopropol alcohol and yesterday that I changed the thermal past on the CPU and the GPU.

When I booted up after that there was a long beep that lasted a few seconds and my speakers a few cracking apart from that everything was normal, but then after a few minutes my screen is odd (for example, green artifacts) and then went black.

After awhile, I started my laptop to the top and the same thing happened with the speakers and a beep but the screen was fine. I opened realtemp and became c 65 - 70 c, then restarted because of an Avast update.

Now, when I turn on my laptop the screen becomes either black or I get a BSOD 0x0F4. I tried to boot from a USB Win7 and repair, but the rest screen went black, so it is not a HARD drive problem as some sites say (from the BSOD error).

BSOD is mainly a product of serious software problems or it seems due to a malfunction of the equipment.
I guess this is NOT question related software since you don't touch software (am I right?). So I think you damaged somewhere during the disassembly of the laptop or the removal of CPU and GPU.

I have no other way for you to control the affected parties? How?
I guess you need a help from a technician who would be able to analyze the material for potential problems.

  • Black screen after the windows login

    Hi, I have a HP Pavilion DV7 notebook with Windows 7 Home Premium installed on it. A problem I've noticed is that, once I connect to windows during a boot, the screen is black for about 1-2 minutes. After awhile, explorer.exe would with desktop, taskbar and icons. I am concerned about this 1 to 2 minutes of black screen after the boot as it did not exist previously. I know I have options such as restoring the computer laptop back to the default state, or by using the system restore. However, I don't want to lose all my stuff, and with respect to the restoration of the system, I'm not sure when the problem happening, as it was some time ago. I have read a Microsoft article, (http://windows.microsoft.com/en-US/windows7/why-is-my-screen-black-when-i-start-windows-7) and tried all the steps with the graphics card and the regestry, but nothing seems to work.

    -Task Manager is able to open when the screen is black (shows explorer.exe running)

    -J' have the drivers on the HP support site

    -laptop is HP Pavilion DV7 3024ca

    You will need to login using the method of trial and error. Please uncheck all of the MSCONFIG Startup tab and restart the system. If the black screen issue is resolved, then check out an application every time and restart the system. This will help you to identify the program interfere.

  • Vista black screen after the loading bar

    I have the problem that I am assuming that almost all users of Windows Vista have probably experiences - the black screen with the white cursor lonely after the loading bar 'Microsoft Corporation'. Here are the steps that I tried to solve the problem, but have not yet worked:

    • With the help of "last known good configuration" brings back me to the screen and the white slider
    • Go into safe mode which brings back me to the screen and the cursor
    • Activate the video mode low resolution which brings back me to the black screen and a cursor
    • Using Ctrl + SHIFT + ESC to appear during the black screen Task Manager
    • CTRL + Alt + Delete does not work on the black screen
    • I do not have access to the installation CD, as it was preinstalled on the computer

    Yes, as usual, what happened after a windows update - I really should stop waiting for something good to these updates.

    I'm under the original version of Vista Home Premium without service pack - these caused a similar problem, but at least I was able to return the system restore.

    Thank you in advance, I know how useful these forums can be.

    Yes, a new installation of Windows 7 was the way for me. Lucky he composed a back all my documents, however. Thanks for the help all. Unfortunately I have no where near more closely to solve the problem, then when I started.

  • Black screen after the attempt to upgrade to windows 10

    I was trying to upgrade windows 7 on a laptop HP Windows 10. The first attempt was via the white windows logo in the taskbar. This attempt was interrupted, probably accidentally turned off the button wifi trying to move the computer. The second time I tried to use windows ten upgraded Installer. I did the usual download and installed up to 99%. He remained on the installation of 99% during the night and the next morning without change. I turned off the computer and he made a series of updates before shutting down for good. When it starts again, it has a black screen but the cursor is there and movable. I tried in safe mode for the repair and restoration of the system, but it did not work. I tried to reset the BIOS to default, but does not. I try to leave the computer turned off for an extended period of time disconnected from the internet to see if that helps. The last attempt to start, windows 7 seems to start but then ends up on the black screen and I held down the power button to stop it. I'd rather upgrade to windows 10 if possible, but if cannot then if can go back to windows 7 will be enough. It worked great on Windows 7 before trying to upgrade, so there is no problems with the computer.

    • Open the Device Manager
    • Expand the section of the graphics card .
    • Find the Display card Driver.
    • Graphics Driver right click and choose Uninstall.
    • Select the check box delete the driver for this device.
    • Restart the computer after the uninstall is complete.

    Step 2:

    Uninstall the drivers of device from the list of programs in the control panel

    • Click Start, select Control Panel
    • Now, click on programs and select programs and features.
    • Find the Display card Driver.
    • Display driver card click right and select Uninstall.
    • Restart the computer after the uninstall is complete.

    Step 3:

    Download and install the latest drivers for the graphics card from the Web site of the manufacturer (ASUS)

    You say you have "defective" material and you want a software solution?

    Any material support - including the drivers and other software that may be necessary to enable a hardware component to operate fully in a given operating system - is the manufacturer of the equipment.  So if you have a problem with your nVidia GT220 video card - your first stop should be nVidia.

    -In addition, you are in the hands of nVidia.
