Can a virus stop network adapters to work? I having a right problem with computers and it just gets stranger, If had 2 problems lately that are probably related seen as its happened on 2 desktop pcs I have. My both machines have had freezes but they haven't froze anymore recently but I've not had it on for too long so the problem maybe still exist. This is now turning into something else. I turned it on last night and it wouldn't connect to the internet after failing to load windows 7, went to a black screen so I powered off and then it repaired intself it said but then no internet. I tried with my old windows xp and no internet on that either, reset netgear router and tried to put in routerlogin.com, but just said cannot find the page, both pcs said this too. So I phoned the ISP this morning and they said all is ok their end and with it not working on both machine it's most probably be a router that is gone, try a mates one. So I tried my mates sky one and nothing but thought that might be because it was a sky specific and then remembered we had an old BT voyager in the loft and try this, it didn't work either when I put in the voyager.home or the ip address to login. So then I tryed the laptop just to see and low and behold it works plugged into this BTVoyager, this is how i'm writing this now. Anyone know why it doesn't connect though to the desktops with ethernet cable. Can a virus of spread, lied dormant in them and now making them freeze and now no internet. I'm just tearing my hair out trying to phathom out why it is not seeing the BT voyager or the netgear, obviously it's not the router afterall but both machines getting a network adapter problem at the same time sounds unlikely doesn't it. Can viruses effect network adapters. Anyone have any suggestions, I've ran both comodo and avira anti-virus and neither found anything the other day. Update: checked the anti-virus on the Windows 7 and it won't let me do a scan, worked ok the other day though as I say. I really don't want to have all to format both machines back to the factory settings as it would take so long to do. Is there a way I can get a upto version of a anti-virus on a disk or external via this laptop thats connected and run some scans. Any advice would be great. Original freezing problem: I really don't know what is happening to my computer, weather its a virus or what. But this is how it happened. 3 weeks ago my psu went wrong in my main Windows 7 computer and I got a new PSU ordered from my PC manufacturer as it was still under warranty. All fair enough, I had a Samsung internal disk drive in my PC with all my storage files on and a Intel SSD for boot. I decided whilst I was waiting my new PSU to arrive I would but my Samsung storage drive in my old Windows XP PC. This is when it happened, I was clearing out and edited some files on my drive when it froze on me just got stuck I couldn't close it with task manager, everything just frooze and you couldn't open anything. I then couldn't see the drive in my disk manager or in windows. So I thought oh well, the drive is dead, so I ordered a new one. I had everything backed up on an external. After that the PC loaded but it took much longer to load and as I say you couldn't see the samsung drive, I took it out and it loaded quick again. Now I got my new PSU and fixed that and all worked fine, great I thought, I figured I'll just try the old Samsung storage drive in my new main windows 7 PC, but this time it shows up fine again and I could few everything again. Oh waste of money buying a new one but great news, then it freezes this PC this time. Oh hell, I take it out and am convinced it's currupt or something. I just run my SSD drive this time and all other drives unplugged so just my ssd boot drive and run my Comodo internet protection anti virus scan, malware bytes and Tune-up but none came up with anything that stops it freezing. But it still crashes my computer, completely randomly, I have to turn off at standby and restart it that way, it maybe hours before it does it again but it will just like have the spinning windows 7 loading circle appear and when I click on anything nothing happens, just freezes. Has anyone heard of this very odd problem, I don't know if its a virus that has spread from the old samsung drive or some hardware fault, or what, I just don't know what to do.
