Suspected Virus affecting audio, networking and performance

Specs: Windows 7, Intel Corei5 2,2GHZ/4 gigs

Hi, and thanks in advance for the help.
My laptop randomly starts showing the following symptoms:
The audio starts lagging and emitting static.
The network adapter completely shuts off.
The fan starts operating quite quickly all of a sudden.
The processes start slowing down considerably.

I have experienced this at least once with overheating, but this time around I am fairly certain that this is not the reason. The fan works completely normally and does not speed up until everything goes haywire. It has been cleaned recently, and the cooling paste is less than 2 months old. I have ran various scan programs like kaspersky, spybot, spyhunter, etc. But there are no certain virus detections. If anybody is familiar with these symptoms please help. Sometimes the breakdowns occur every 2-3 minutes, sometimes after more than 5 hours of usage, even when the hardware is used to max. Rebooting the laptop always fixes the problem temporarily.

No idea what it could be, lets start with this.

Run ESET & post the log please. This scan may take a very long while, so please be patient. Start it before going to work or bed.

Why Would I Ever Need an Online Virus Scanner?
I already have an antivirus program installed, isn't that enough?

Once onto a machine, malware can disable antivirus programs, prevent antimalware programs from downloading updates, or prevent a user from running antivirus scans or installing new antivirus software or malware removal tools. At this point even though you are aware the computer is infected, removal is very difficult.
5: Why does the ESET Online Scanner run slowly on my computer?
If you have other antivirus, antispyware or anti-malware programs running on your computer, they may intercept the scan being performed by the ESET Online Scanner and hinder performance. You may wish to disable the real-time protection components of your other security software before running the ESET Online Scanner. Remember to turn them back on after you are finished.
17: How can I view the log file from ESET Online Scanner?

The ESET Online Scanner saves a log file after running, which can be examined or sent in to ESET for further analysis. The path to the log file is "C:\Program Files\EsetOnlineScanner\log.txt". You can view this file by navigating to the directory and double-clicking on it in Windows Explorer, or by copying and pasting the path specification above (including the quotation marks) into the Start ? Run dialog box from the Start Menu on the desktop.

Alas, I cannot do the ESET scan. When I start it and it begins downloading the definitions, usually I reach the moment when my network adapter dies out. And even if I leave it on, when the computer succumbs to the problem, it just slows down tenfold and it's more possible that it will melt and turn off, than to finish the scan. Any other suggestions I can try?

"Any other suggestions I can try?"
Download it from a good comp onto a thumb drive & run from there. Use Safe mode if you have to.
