Windows 7: BSODS doing different things

could it be possible that my network adapter is going out? currently i cannot connect to my router, i changed my ethernet cable twice and still nothing reinstalled my drivers twice with no avail, when i check the status of the network card thru device manager it says its working fine, but it will not connect to my router via ethernet. internet is working and wireless is working fine. computer was working earlier then just completely stopped.

Have you followed the instruction given in post #9 and post #10?

yes i did, didnt have any problems. like i said today my internet just completely cut out on me. i believe my marvell network adapter has gone out. windows says its working but i cant get it to connect to the router and ive tested mutliple cables. im running it on wireless right now and am not having any issues so far. so ill let you guys know how it goes tomorrow.
