Go to system devices.
There will proberly be 4-6
ram/memory controller listed there.
Now they may need an update.
so try this:right click on one of them and then on update driver,choose install from a pesific location advanced.
Then choose dont search I will choose driver to install.Click next.
You should see whats listed and go for digitaly signed drivers.
Or is there nothing listed there for drivers?
You could actualy do this for most of your hardware then maybe you would install the correct didgitaly signed drivers.
You do not have to restart each time just keep going untill you have updated every thing on that list?
I know it will take time but it may hopefully sort these problems out?
You could then do this for ALL hardware,please check the right driver is installed for you
CPU by see wich driver is recommended in update driver or wich one is already installed.
As often when we download from larger pc companys we do not download individual drivers but a driver package.Thus the first driver in the list is not always the one to install.
If you are not sure wich driver to install still choose install from specific lacation advanced however then choose search for drivers in these lacations,uncheck CD/Floppy and check the box include this location in search type in the drop down box C:/WINDOWS:system32 click next.
Again you can download the driver packages and put them to CD/Floppy and then choose install from CD/Floppy and the PC will search the disks for the correct drivers if they are there?
