XP slow and showing errors often, help pls

Hi,
XP was too slow and I tried to re-format all partitions and re install the XP too.

And Its still showing some errors like this :

Generic Host Process for Win32 Services has encountered a problem and needs to close. We are sorry for the inconvenience.

szAppName : svchost.exe szAppVer : 5.1.2600.5512
szModName : schedsvc.dll szModVer : 5.1.2600.5512 offset : 00008da8



And in task manager I can see lot of svchost files running..




And My Browser Chrome is showing some errors like : Runtime C++ Error,etc FireFox Also Slow.

Is there any ways to find out what is wrong ?

Again its a fresh installation of XP..
Thank you.

Run the disk clean up (Start - All Programs - Accessoroes - System Tools - Disk Clean up). Also system performance depands on the Antivirus. What antivirus you have? Uninstall google chrome and firefox and reinstall one of them. I would suggest Google chrome since it is really fast.

 

i have kaspersky,

 

i did what you told, but i still have problem
