PC doing crazy things.. but only when using a browser on the internet

post #1 of 5
Thread Starter 
I having a strange issue with my PC. Its not currently overclocked and NOD32 does not pick up any virus’s.

Some days the PC is fine with no issues other days (more often than not the issues are occurring).
Spec (As per sig) Windows 7 x64 (legit), Opera (Latest Version) & Internet Explorer

Basically the PC works perfectly no issues what so ever until I open a browser. The internet is very very slow and the mouse stutters across the screen when the page is loading. Music will also skip and freeze.
I’m wondering if its a hardware issue since the mouse is acting like it does when a hard drive is on the way out (Its not i’m using a new SSD). Fairly often the “Exclamation Mark†will appear over the wireless signal bars showing there is an error on the connection. Strange thing is my iphone works perfectly well in my room so it’s not a signal issue and all other PC in the house are fine.
Sometimes “CMD†“ipconfig /release†– “ipconfig /renew†can make things better. I’ve also tried resetting the router numerous times.
Oh also when I can eventually open up a speed test website the internet speed is about right with 4mbdownload, 32ms ping and 0.5kbps upload.
Harware monitoring doesn't show anything out of the ordinary.

Any suggestions?
I’m thinking
1)Boot into safe mode with networking to see if it happens there.
2)Try a USB 3G dongle to see if it happens over that connection.
3)If it works fine over 3G it may be the wireless card??

Have you tried running any other malicious software removal tools like Malwarebytes Anti-Malware? If not try it as it just incase it's something that hogging your browser.

NOD32 won't necessarily spot everything. I always run Malwarebytes at least once a week even though I use Nod32 for my AV.

Currently browsing using a 3G dongle on the very same PC with music playing and everything is 100% ok!

So looks like its not a virus and the issue is ether A my Wireless N Router or the Card in my PC. I was pretty certain it was hardware related since the mouse stutter was so reminiscent of a dieing hard drive.

Thanks for the reply. I'll give the software a whirl anyways!

Try updating the firmware on your router as well, though it is more likely that it is dying than lacking proper firmware.

Fixed a similar issue (minus mouse lag) with my computer a few years ago.

This one is probably a shot in the dark but before fiddling with hardware etc, connect to the dodgy connection, then try right clicking on your internet acces icon and selecet troubleshoot problems.

I can't remember what it was now but I did this when I had connection trouble a while ago (admitedly it wasn't affecting other hardware) but it went through a load of checks then fixed the problem. Worth a try.
