I have been struggling with my pc dropping internet connection and not seeing the router as well as it freezing at random times, from 5mins use to several hours, but lately its alot more. Its a cyberpower system machine I bought in oct 2008, its had ALOT of use. See below for system specs below please if needed.
It will freeze at all sorts of times, does not matter which application I have open. I have to hard reboot. It will also freeze on shutdown sometimes. I get all sorts of errors on connection loss, it will say the default gatway not available, it will ask me to reset my router too. It resets Local Area Connection adapter all the time, when I try to resolve the issue. It also says "Local Area Connection" doesn't have a valid IP configuration, and resets all my settings back to Obtain IP addresses automatically, as well as Obtain DNS server address automatically in the Internet Protocol Version 4 settings. If I put all the IP addresses and default gateway stuff back in without resetting the router, it then says Troubleshooting couldn't find the problem. Resetting the router usually does work. But not always, sometimes I need a restart. It Sometimes it works if I restart, sometimes it still won't see the router. *pulls hair out*
I'm totally at my wits end now with this, I have no idea what's going on and I'm not computer savy at all, I'm just trying to get through this step at a time, to try and figure out what is doing this. I really need some more help please. I would send machine back to cyberpower but they are halfway across the country.
WHAT's BEEN TRIED:
I tried putting the IP address in as static, put in the subnet mask, and default gateway.
I use the Preffered DNS server IP in there as it helps use network gaming and platforms better like SecondLife.
I've tested the router network with same cable I use on another laptop so the cable is fine.
Changed ASDL filters twice.
Bought new router.
I've replaced my harddrive.
I've tried two different driver versions for my network card which is a Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller
I've resit my memory.
Tried restoring system to a few days before it started freezing again.
I've reinstalled windows a few times now, usually it works for a while (week or two) after a fresh new install.
Its a fresh new windows 7 I bought as the machine came with vista.
I've manually tried to put in all the drivers I need myself as I don't have the disk that came with my machine. (I have no idea if I've done that right)
Sent it in for a service clean and checkup.
Turned off the option that windows shuts my network driver down to save on power.
Thank you very much and all help welcome.
