    Johnny, Welcome to the Lounge

    This sounds like your graphics card might be overheating. Since it does not happen until a couple of minutes after you log on, I assume before that point everything appears ok. You could try new drivers to see if this works, but I suspect you might need to clean the laptop out a little. Use a can of compressed air in one side of the laptop while holding a vacuum cleaner near to opposite side. You could also try removing the bottom access covers and blow through them. There are many sites a Google search (Clean Dirty Laptop). Here is just one such article.

    Laptops are more difficult to clean than desktops. This might be a time to visit a trusted tech for a more complete cleaning.

    If the blackout and connection dropping issues are related, I'd want to check ACPI (power-saving features) and test hardware and security (Malware?).

    Keeps us updated on the steps you take Johnny.

    Thank you everyone for replying, unfortunately my brother, the owner of the computer, decided to restore the c omputer. But I don't think that solved the problem because it again blackscreened while moving files from my passport. I will try what Ted suggested and reply back after that. Also the internet problem seems to have been fixed by the restore but I will post if it does it again.

    This new info lends more credibility to the heat problem theory. Unfortunately laptops are much more challenging to clean out. Other than the compressed air, vacuum attempt, it is much more involved opening a laptop, and generally not for the inexperienced person.

    I have opened my computer before to install ram and I know where things are so my only problem is that I need to buy compressed air.

    BTW Ted I think your quote thing on the bottom is messed up because it says MHz where it should really be GHz.

    Just a thought, but has Windows been validated? Not doing so would also cause a black screen.

    You can check by doing the following.

    1. Click Start and in the Search box, type: activate windows
    2. Click the link which appears and if it has been, you'll see a message that validation was successful.

    You can also check online here: http://www.microsoft.com/genuine/validate/

    1. Your welcome Ted. 2. Xlracal yes it has been validated. And 3. The internet problem appears not to have been fixed. Could my wireless adapter be overheating aswell?

    Heating problems in a PC, especially the smaller spaces in a laptop can cause all kinds of problems. If this is indeed a heat problem, it's possible to overheat components to a point they fail. In extreme cases I have seen PC's that will not even post after running for a while.

    The PC has to post before it can begin to boot.

    POST stands for Power On Self Test which is performed every time your computer is started prior to the start of the boot.

    If this were a desktop perhaps this would help. I doubt it would help with a laptop because of the small spaces compared to a desktop.

    I would try the simple cleaning we have already discussed. These heat problems in PC's are quite often caused by dust and debris pulled into the cooling vents of the PC. In laptops, quite often the way we use them can contribute to the problem. Do you use the laptop on your lap or in bed and let it lie on the bed? This can lead to further contamination.

    Laptops should always be used on a hard clean surface, such as a lap desktop or on a desktop. When used on a bed, for example the soft surface will lead to blocking the cooling vents, plus the soft material can be pulled into the cooling vents.

    I think he means start up, i.e not get past bios screen. Also with a lap top care must be taken if using your lap that your legs do not block any vent holes or laptop is not put on soft cloth or toweling etc. (Pointless calling them laptops when your lap blocks vents).
    You can buy cooling mats/pads that have fans on to assist in cooling. Such as these from Amazon.co.uk.
