T400 Slowdown?

So I just got a 14.1 T400 a couple weeks ago, and the first week it ran fine. Yet lately the laptop has been slowing to a crawl, especially when I'm using the internet. A first I thought it was firefox, so I uninstalled and reinstalled but the IE is slow as well, and browsing folders have started to show lag.

This might be a software issue (Vista bog down), but I just want to know if anyone with a T400 experienced this and what can be done.

Thanks. And if it helps, I upgraded to 2GB ram and 2.4 GHz CORE 2 P8600

 

Might be some type of malware or virus. Have you tried scanning your computer?

Free tools I recommend are Avira Antivir and SuperAntiSpyware.

 

I don't think so. Vista was remarkably clean out of the box. Arkit3tk's idea of malware or even a common virus was the more likely.

 

check which power scheme you're using. if it's lowest, it will limit the cpu

 

I ran a scan and came across a ton of tracking cookies, otherwise there were not viruses or malware. I also changed the power scheme is optimal performance, and I'm still not seeing a change

Any other thoughts? I checked my programs at start-up and disabled a ton of them, so my boot-up time has actually improved but performance overall is the same.

 

Are there any spikes in CPU during these slowdowns? If so, during a slowdown, open up task manager and sort your processes by CPU (descending) and post the top 5 processes here.

 

Are you running an anti-virus or any other security programs/suites? Maybe that is slowing your down.

You should run Autoruns (from Sysinternals) and check your task manager for any suspicious programs.
