it might take some time being a freeware driver solution
Note: it will find all of your outdated drivers

This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.

Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.

good luck!

Thoroughly flush out the coolant expansion tank and cooling system, radiator , engine block ect... with a commercially available cooling system flush (Prestone or any other brand). Oil will damage the rubber cooling system hoses. Refill the cooling system with the correct amount of fresh antifreeze and drive the car after the cooling fans have cycled on and off. When the cooling system has cooled down top up as required and keep an eye on the cooling system for a few weeks to see if the problem reoccurs or if someone had inadvertently put oil in the reservoir.If not I'm more leaning toward a blown head gasket. it will run fine but you will have to keep the water clean out. to fix it buy a head gasket and surface the head..you have a blown head gasket

how can i replace the cooling system connector to my tahoe 1999?
I already purchased a new cooling system connector.
Should I pull out the hose from the old cooling system connector unscrew the old one, screw the new cooling system connector and insert the new one?

Check the settings to see of it was programmed to do so.

Maybe the heater core is plugged or perhaps you have an air pocket in the cooling system. Try and bleed the cooling system once more.

Open windows movie maker from the start menu and use it to record video from you built in web cam

First is a good sign that if you click the Icon form the webcam software, and you see your picture. This indicates that the webcam drivers were installed correctly.

You will need a software that support the webcam to be able to use it. You can Try Skype (http://www.skype.com/), or MSN Messenger (http://im.live.com/).

Those programs will detect your webcam and will enable video chat, that way you can use your cam to communicate with others.

Hope this helps..
