I was just about to sign off when I got the notification of your post.
IF ALL YOU HAVE INSTALLED is Windows 7 and the drivers, and NOT any programs, then you clearly have either a driver porblem or a hardware problem.
As you said in your closing post before you decided to proceed with the clean install that the HD is Western Digital, the checking of that using the Western Digital tool will not be difficult.
However in view of the fact it is not that old, I think you should proceed firstly with a ram check.
As you have two sticks of ram I think, remove one of them, taking the usual anti-static precautions and try again, then change them over so that you are using the other stick.
Remembering of course to populate the slot necessary for the system to boot.
Normally the one nearest to the processor or if a dual core and you are going to run in single core, your are best referring to your motherboard manual
Alternatively use MEMTEST.
Please see my post 39 on this thread.http://www.geekstogo...on/page__st__30
Returning to the all that is installed are the drivers.
I would examine your graphics driver and your network driver.
If the graphics driver is Nvidia and you have recently accepted an update for it, I would go back to the Nvidia site and install a previous one.
Do you mean you have installed the drivers AFRESH after the install of the O/S.
If you have a Nvidia N Force Ethernet driver see thishttp://forums.nvidia...c=100637&st=120
I think it going to be a question of examining the hardware, I will post again tomorrow with some more tests and then the drivers- If I remember correctly this is a 64 bit operating system - is it not - please ensure that you have not installed a 32 bit driver
One thought before I go, you haven`t overclocked have you.
If so, altering ram timings and voltages etc in the BIOS and general overclocking can very easily be the cause.
Sorry I cannot spend more time now, but it is 0046 hrs.
