Computer slow or is it just me?

Solution 1:

On Windows 7 there's a great utility called "Resource Monitor", it will show what apps are using the disk/cpu/network/memory (sort by the different columns to zero in on a particular resource usage).

Fire it up and watch what's running. Also, have a look in your Event Viewer to see if there are any services having a problem during start-up.

Solution 2:

Use ccleaner to clean up your PC

Then defrangment the C drive (windows partition)

Last thing, click start, type msconfig and press enter.

In the start up tab, disable all the item and enable which you really need.

Restart your computer abd check if some thing is missing while start up. Repeat the msconfig step.

Solution 3:

I have the same issues like you. Last year I had some strange behaviour where my Screen turned black for half a minute or so after logging in. I think, the problem might be Steam on my computer (it was last year - I still have to check if it is the problem again) and it could also be yours.

But if you want to clarify that, I suggest you to run Soluto on your computer.
Soluto monitors all starting programs on boot and logs, how many seconds they delay your boot time. With Soluto, you should be able to resolve which app is slowing down your machine on boot.
