I just did a clean re-install of Vista x64 on a new hard drive (old drive crashed). Here's the problem:
Using my ISP (Roadrunner Carolinas) speed test site; I get around 200 to 400 kbps download speeds using IE in normal mode. If I boot to Safe Mode, I get around 3500 to 4500 kbps, which is what it should be (this is what I used to get in normal mode before I re-installed Vista).
Running the same speed test with Firefox, I get around 1500 to 2000 kbps in normal mode, but if I try to download a file it transfers at only the 200 to 400 kbsp rate (if I'm lucky).
Here's more detail about the system and what I've done so far:
Installed all updates including SP2.
Using Windows Firewall, no anti-virus.
Updated network drivers
directly from NVidia (Chipset is nForce750i)
Updated graphics card drivers
directly from NVidia
Disabled all LAN protocols except for Client for Microsoft Networks and IPv4
Connected via ethernet cable directly to cable modem, no router.
I've deliberately refrained from loading anything but the basics until I can get this sorted out.
This really the second clean install I've done in 24 hrs. After the first one, I upgraded and added a lot of software and add-ons before I figured out the connection problem; so I decided the easiest fix would be to re-format and start over, checking each step to see what caused the slow-down. Unfortunately once I did the second clean install I tested right away and I had the connection problem from the get-go. Since then, any action I took (loading upgrades, drivers
, software, etc.) I have run the connection test after every step.
My skills with computers are a bit better than average but this is way beyond me! Thanks in advance to anyone who can point me in the right direction!
