Since a few weeks my pc at home is suffering from slow internet speeds, but not always. 2 out of 7 days the speed is normal, the other days it's very slow (reminds me of my old 56k modem). I'm running Windows XP on it and it's on a wireless home network.
Rebooting doesn't help, I've ran a full virus scan and spyware scan: nothing was found. Another strange thing is that my laptop computer doesn't have this problem, not even when the pc suffers from the low speed, so it isn't my internet connection itself.
Is there anything else I can check to fix this problem?
EDIT: pages load very slow, downloads/torrents are slow, etc. Yes, I checked the CPU load: nothing special. The PC is further away from the wireless router than the laptop usually is, but this is only a few meters, there are no walls in between and this worked great for the past 3 years...
Never tried running speedtest... might try that tonight.

Specifically, how does the problem manifest itself? Lag in gaming? Slow page loads? Poor download speeds? Have you checked the processor load at slow-downs? Verified your broadband speed during such periods (http://www.speedtest.net/)?
