Can't tell if infected or not (Seems like I am)

[DisgruntledCarthaginian]

Starting about 2-3 weeks ago, my PC began to lag alot more when it came to the internet and other applications, I began losing connection alot more, and, me, being suspicious of it, decided to run scans (I run them daily).

Full, Quick, Cusom, on things like Avast, MBAM, SUPERantispyware, etc, all came up with nothing except tracking cookies.

A few hours ago, my computer randomly BSOD'd.

Its 4 years old, Windows 7, I believe 64 bit, and an ACER.

I'd like help to see if I'm actually infected or not, and, if I am, how to clean my computer.

All help is welcome!
