My computer is extremely slow after start-up. Should I re-install my computer?
May 28th, 2010
I’ve unchecked all unnecessary programs from the start-up (Run > msconfig > Startup). I’ve uninstalled every program I haven’t used in over 2 months. And I’ve defragmented.
Still, my computer is very, very slow immediately after the start-up; it takes about 15 minutes after booting up the computer for everything to work normally. Usually, if I try to even open the My Documents folder, it lags and takes forever to load up.
Should I re-install my whole computer or should I do something else?


click on start button
select “Run”
in the window, type “msconfig”
you get to see various tabs.. select “Startup” and then click “deselect all” at the bottom part of the window..
it makes your startup a bit faster..
hope it helps..
Install Linux (Ubuntu)
If it were me, I would save all your documents, pictures and music, and then format and reinstall Windows.
yes , save all your files and do a reload, this should be done every year atleast with windows
do a spyware scan and a virus scan. download avg and/or avast from download.com also download spybot & malwarebytes. update the definition files on each & run full scans.
These programs are all completely free and work well.
If your virus/spyware free, there are a couple things you can do get your computer working faster. If you using your computer for normal stuff and not gaming. You don’t always need more RAM you just need to perform a few maintenance task.
First, if you haven’t cleaned your registry in a while. This is necessary. Your registry holds all the information regarding updates, installs, un-installs etc. Each one of those events produces a key. That key needs your PC’s resources and free space. So, if you clean your registry, you make more resources available for speed. Do a registry scan if you got more than 20 errors you should clean it.

2. Click Start, click “Control Panel”, and then double-click “Internet Options”.
3. On the General tab, click “Delete Files” under Temporary Internet Files.
4. In the Delete Files dialog box, click to select the “Delete all offline content” check box , and then click OK.
5. Click OK.
3. Manage your startups. Your excess CPU usage is due to too many programs running in the background. You can cut these to barebones by alter your msconfig. Here is how:
