Internet speed problems
I got a new PC and realized the internet connections is so slow on it. So I decided to do a few comparisons of it to my laptop. Both PC and Laptop were kept right next to each other the entire time. Internet speed was tested on speedtest. The modem/router is far from me so I use a powerline adapter (85 Mbps) and connect it to my PC/laptop for direct wired connection or to my other router for wireless connection.
Specs for laptop network adapters: Intel(R) Centrino(R) Advanced-N 6205 #2, and Intel(R) 82579LM Gigabit Network Connection.
Specs for my PC network adapters: Realterk PCIe GBE Family Controller, and TP-LINK Wireless USB adapter (150 Mbps)
Both PC and Laptop register the same IP address/DNS server/etc
Wired---
Laptop -> ~ 8Mbps as reported on SpeedTest
PC -> ~1Mbps as reported on SpeedTest
Wireless---
Laptop -> ~ 8Mbps as reported on SpeedTest; Speed stated on connection status: 144 Mbps
PC -> ~1Mbps as reported on SpeedTest; Speed stated on connection status: 72 Mbps
I tried making an internet bridge to my PC through my laptop to see if that did anything, but the results were:
Bridged Connection---
Laptop -> ~ 1Mbps as reported on SpeedTest
PC -> ~1Mbps as reported on SpeedTest
Can anyone help me? I want my PC internet speed to be at least 5 Mbps

The fact that you're getting the same throughput on two different network adapters eliminates the network drivers as a possible cause.
It also eliminates any network interface settings (such as connect speed, full/half duplex, etc.) that might otherwise limit the speed.
Another thing it eliminates is bad ethernet cables if you're getting the same speed through wireless.
It sounds like it's something related to the computer itself, although normally there shouldn't be anything limiting the network speed like that.
I'd update both network drivers anyway, just because it's easy and worth trying.
Also I'd run full scans with both an anti-virus scanner and an anti-spyware scanner to be certain nothing evil is using bandwidth or limiting bandwidth.
Something else that might be worth doing just to eliminate everything else (although I realize it might be a hassle) would be to move the desktop in next to the broadband modem and connect it directly to the modem/router and see if you get the same results.
One more thing to try would be to reset the TCP/IP stack. Normally a bad or corrupted TCP/IP stack simply prevents any Internet connection at all, but again this is a simple thing to try and can't hurt: http://support.microsoft.com/kb/299357
