Windows 7: Downloading makes 7 really slow

Well, my download speed is unaffected, it makes the system slow.

Nikolay,

I've had this kind of problem(s) in my Video editing days, from what I know "lag" or latency spike can happen if your hardware are using the same IRQ (iirc). Here's my "case" back in the day: I have a Video Editing card, a Pinnacle Pro ONE. When I'm capturing, the Audio will lose sync with Video (I'm capturing analogue source using the card's I/O). What I did was, I go to "Device Manager" switch the "View" to "Resources by connection". In my case I know that the Pinnacle Pro ONE card is "fighting" with another card, I didn't know what... Once I see "Device Manager" I knew that it was fighting with my Video Card for IRQ time (OMG!!). Once I know that, I move my Pinnacle Pro ONE card to another PCI slot, which solved my issue.

Here's what you can do, check "Device Manager", switch it to "Resources by connection", see if your AUDIO device (whatever it is) shares same IRQ number with another device. Make a screenshot, we then can all see what is happening...

Just took a look at my IRQs and found my audio and network adapter using the same IRQ.. Both having the problems I've been having (audio + downloading)..

There you go... Easy way out, don't use that network interface, use another interface... an Add-in interface or an external one, you pick. Hard way would be look for a way to change that, make those 2 devices NOT sharing an IRQ.

Both are integrated into the motherboard though, how do I go about changing that?

The hard way would be disabling ACPI completely and manually assign IRQ and DMA to each and every hardware you got (that is NOT RECOMMENDED), or buy an NIC, and use that instead.

You should be able to change it through the Device Manager.
You can also,,, try uninstalling the device and reinstall it and see if it will grab a new one.
Or as stated, disable one of the conflicting devices and repalce them,, either is ok.

But this is hardware or driver issue and not a windows 7 issue exactly.

My sister's laptop also gets reduced performance and choppy audio when downloading with my connection.

Then I might try replacing the router and/or modem.
Could have bad hardware there.

As well as all the cables just to be sure.

I think the IRQ suggestions have the best chance to be the cause. Why don't you connect directly to the modem and leave the router out - just to eliminate this as a possible cause.
