High CPU consumption after applying thermal paste!

[dud3rulz]

Hi guys,
I applied Cooler master thermal paste to my CPU and GPU of Dell XPS 15 laptop. Oddly, i noticed a bump in CPU usage than before. At idle my CPU consumption was less than 5% (no programs running). Now it constantly uses above 30% at idle. Also, a USB port stopped working. Can anyone suggest a solution ?

Laptop specs: Core i5 2.53 GHz
win8, 4 GB RAM, Nvidia GT 420M

There is ABSOLUTELY NO RELATION between TIM and high CPU usage. Scan your pc for malwares and stop unnecessary programs running in background.
