My comments: I hope you tried out some stuffs here. I did and they worked.
Here's another set of 10 things you can do.
11. Update your drivers
If you are experiencing any kind of performance issues,
checking you're running the latest drivers should always
be one of your first ports of call. The drivers provide the
link between the hardware inside your PC and what you
experience, and companies constantly update them to iron
out bugs and optimise performance. Search the
manufacturer's web site for the latest editions of your drivers.
12. Tweak advanced settings
Even if there's no new driver for a device, you may still be
able to squeeze more speed out of it. Click Control Panel
> System and Maintenance > Device Manager, then
expand the Network Adapters section, right-click an
adapter and select Properties > Advanced. You'll probably
find all kinds of settings that aren't available anywhere else,
and it's much the same for any device with an Advanced tab.
13. Stop the Search index
The Indexing Service is a handy way to speed up searches,
but if you rarely go hunting for files this can be turned off.
Open Computer, right-click on the hard drive and clear the
Index This Drive box.
14. Turn off legacy support
Launch REGEDIT, and browse to HKEY_LOCAL_MACHINE
Set ntfsdisable8dot3namecreation to 1 and it won't
create DOS-style shortened versions of file names;
setting ntfsdisablelastaccessupdate means Windows
won't update the Last Accessed date on a folder when
you view it. Both tweaks will help improve drive
performance a little, but could break old software.
15. Get more speed from your SATA drives
You can squeeze a little extra performance from a
SATA drive by going to Control Panel > Performance
and Maintenance > System > Device Manager > Hard
Drives, then right-clicking your drive, selecting Policies
and checking Enable Advanced Performance. Beware:
Microsoft says this increases the chance of data loss if
the drive loses power. Only do this if you have backup
like a UPS (Uninterruptible Power Supply) or are willing
to take the risk.
16. Plain but speedy
Click Control Panel > System and Maintenance
> Performance Information and Tools > Adjust
visual effects > Adjust for best performance to speed
up PCs with a sluggish video card. Check Enable
transparent glass if that's a little too plain.
17. Give ReadyBoost a go
Slower PCs may benefit marginally from using a USB
drive as a ReadyBoost drive - but it's no substitute for
adding more RAM. Before you start you need to make
sure your USB memory card is up to the job. You'll need
a minimum of 256MB storage and a maximum of 4GB,
and it needs to be capable of specific speeds: 2.5MB per
second for random reads and 1.75MB per second for
random writes. ReadyBoost will test your memory when
you first plug it in and, if it's not up to scratch, ReadyBoost
will refuse to use it.
18. Remove SP1 uninstall files
If you're running short of space and Service Pack 1 is
causing you no trouble at all, and you're sure you'll never
want to remove it, then use the tool that Microsoft has
provided to clear the 800MB of uninstall files. Simply type
vsp1cln.exe into Start Search and press Enter to launch it.
It'll erase your old files, free up some disk space and you can
get on with enjoying your faster, more reliable PC.
19. Roll back to a faster, happier time
System Restore enables you to roll back Windows Vista to an
earlier point in time without affecting your files. You can run it
from within Windows Vista or in Safe mode by clicking Start
> Control Panel > System and Maintenance > System
> System Protection > System Restore.
20. Turn off System Restore
In Windows Vista you can set restore points, so you
can return to a state of PC peace if things get a little
stormy. However, setting these points takes lots of
disk space and processing power, and so if you suffer
poor performance turning off this safeguard might give
you the extra boost you need. Be sure to back up
regularly, though - and strike tip 19 off your list if you
do turn off System Restore.
