[SOLVED] Certain Websites load slowly only on one device

[DillySharp]

Hey guys, so as the title says some of the websites I'm trying to access, such as gmail, take almost a minute to load- no exaggeration. While others, such as Youtube, take less than a second, and seems to be only for my desktop computer which is connected to my modem using Ethernet.

So the things I've noticed and what I've tried.

• Speed test: my desktop either can not connect correctly to the server, or it gets 12 MB up, 0 down.
• When I connect my laptop to the same Ethernet cable, the problem isn't present and I get 12 MB up and 3 MB down.
• When I run my desktop in safe mode w/ networking the problem isn't present. All websites load properly.
• When I scan my computer with Kaspersky anti-virus, no viruses are detected.
• I've restarted my modem a few times,- that did not help.
• And lastly, I restarted my computer, but not in that order of course.

I think the problem is software related on my computer. I just need to find the problem. If you guys have ideas, please let me know.
I really don't want to uninstall and reinstall my OS.

My malware scan did not detect a threat.
I have tried internet explorer as an alternative web browser- it did not resolve the issue.
