System lags while downloading .

[Deeko78]

Hi all at W7 forums.

I'm having a problem I just cant seem to figure out. Recently upgraded to Windows 7 Ultimate 32 bit, from Vista, & have loved it so far until I had broadband connected at my new flat.

Whenever I try to download anything at all as soon as the speed reaches around 100kB/s my system seems to lag unbearably. My mouse movement get so jerky its very difficult to do anything.

Checked task manager & everything is fine there. CPU & memory usage is fine. Also checked all my drivers are updated, defragged both my hard drives, ran virus, & malware scans, but it still happens as soon as anything is being downloaded. The instant I stop the download my system behaves normally.

Googled around & see that it has happened to a few others, but no real solution to the problem. Dont think its a network problem as web browsing & online gaming are fine, as long as I dont download.

Any help would be greatly appreciated.

CPU Type - DualCore AMD Athlon 64 X2, 2600 MHz
Motherboard Name - Biostar MCP6P M2+
Motherboard Chipset - nVIDIA nForce 6100-4xx, AMD Hammer
System Memory - 2048 MB
Video Adapter - NVIDIA GeForce 9600 GT (512 MB)
Disk Drives - ExcelStor J9250S (250GB), Seagate 7200.8 (300GB)

Thanks Nemix, but I read that thread earlier. Poor guys still having the issue by the looks of it.

Thought it may be the IRQ problem as my network adapter & standard enhanced PCI to USB host controller share the same IRQ of 20. Spent 2 hours trying to change one of them, but there are no options in my bios for changing IRQ's, & I couldnt find any info on how to do that.

Do you have the latest OEM drivers for your motherboard from NVIDIA download site?

Is your networkcard onbaord? If so, is it Realtek is the device manager?

 

[Deeko78]

Yep. All my drivers are up to date. My network card is onboard, Nvidia nForce Networking Controller.

Not sure what your asking about Realtek, but yes thats my audio controller in the device manager.

Thanks for your time.

 

[Nemix]

No, because some motherboards can install both NVIDIA network drivers and Realtek drivers if the chip onboard is Realtek.

My old nForce 2 motherboard allowed me to do this with the onboard soundcard.

I've checked out you motherboard specs, Realtek does not offer drivers for you NIC becuase it's PHY.

Sorry, I cannot help you.

 

[Deeko78]

No probs Nemix.

Thanks anyway.

One other thing I forgot to mention, have to updated to the latest BIOS for your motherboard?

Also, have you tried diagnosing the problem in Windows 7?:

Start>Control Panel>Network and Sharing Center>Change Adapter Settings>Right Click 'Diagnose" on your NIC Adapter.

 

[Deeko78]

Yep, BIOS is up to date also.

Just tried diagnosing the network adapter & it came back with this -

Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.

 

[Frostmourne]

1) Install the latest nforce chipset driver.

2) Disable the COM, Serial and any other unnecessary ports in the BIOS.

3) Reboot.

 

[zigzag3143]

Yep, BIOS is up to date also.

Just tried diagnosing the network adapter & it came back with this -

Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.

What are you using for your network protocol? homegroup? Do you have any other machines on the network?

[Deeko78]

Frostmourne - The nforce chipset driver is updated. I'v checked my BIOS & cant seem to find any settings relating to disabling ports.


Ken - Yes, I'm on the homegroup, & there are no other machines on the group.

Edit - Just changed the settings & left the homegroup.

Hi everyone!

I Finaly found a thread where people talks about my problem
Yes, I got EXACTLY the same, my computer is lagging to death when I'm sharing ( up/down ) data with my network. I can't even use my mouse correctly.

First, I noticed it using MegaManager ( the megaupload tool ). I Thought it was this program causing the lag. But today, after a lot of tests, I got a lot of programs lagging my computer while downloading/uploading from them:

MegaManager, PS3 Media Server, Firefox and even Windows Live Messenger.

I Found a temporary solution, I execute thoses programs from a Virtualized XP ( Virtual PC ) and it really works. But I don't want to do this everytime, so if someone found a real solution, I'll appreciate.

Thanks

I seem to have found the root of my problem after noticing a few more topics on here.

Malwarebytes Anti Malware. After uninstalling that program everything was working as it should be.

If you have that installed thepopol777, try getting rid of it & see if that helps. Remember replace it though. Try Spybot S&D, or Adaware.

Best of luck.

 

[thepopol777]

Seriously????!!!
I got MalwareBytes Installed!
I'll try unistall it right now. Thanks for notice this here, that's nice.
However, how could MalwareBytes causes the problem? I mean.. I know there is a "Realtime protection" on the Pro version, but If you uses the free version ( only for manual check ), does it still causes the lag?

Thanks anyway!

Edit: Oh my dear lord, IT WORKS! Thanks dude, I've read your reply a minute before my Seven full Reinstall. thanks again.
