I never met this kind of problem before, I have no idea what to do???? Help!!!

Check the settings in the bios. Make sure your CPU cache is turned on. Make sure the bios ROM is shadowed. Make sure your video area (C0000 - ) is shadowed. If you're not sure they're right, load bios defaults. If you have mboard jumpers for setting your cpu, etc., look in your manual and make sure they're right. If you don't have a manual GET ONE - if it is still in the Dell case, it isn't that hard to find info on the Dell site. In Device Manager - Drives - Generic IDE.... - Settings make sure DMA mode is turned on. Do the same thing in Cdrom - Settings. Other than that, you're probably loading too much crap when windows starts up. Start - Run - type: msconfig - look under Startup tab. Some are default Windows ones - ScanRegistry, System Tray, TaskMonitor, LoadPowerProfile, SchedulingAgent - they are supposed to run all the time, and are necessary for the normal operation of windows - normally they can be left as is. There will also be at least one entry for something to do with your video display adapter, usually identifiable by something indicating a brand or model name of the adapter (e.g. ATI....). If you use a software firewall, there will be at least one entry for that. There will be at least one entry for your anti-virus program (e.g. Norton Anti Virus - name usually starts with NAV). Everything else other than these entries can be disabled by clicking on the box to the left to remove the checkmark. Try disabling everything not necessary and see if your problem goes away. If it does, re-enable half, check again, etc. Eventually you may narrow it down to what causes the problem. A lot of programs install a startup program that only help the main program load a few seconds faster - you don't need them to use the program. e.g. if you don't use MS Messenger all the time, unload (uncheck) MsnMsgr from the Startup programs.

forgot to tell you, I have a fresh installed windows 98, I formatted the hard disk before...I have set the BIOS to default...but it still not working... important: when I was installing windows 98, everything was fine. even when the windows 98 while load when startup, the mouse is fine...it turn bad when the desktop icons show up and the start botton shows up, and then it become 20-50 times slower than normal speed.

Did you install the correct gfx driver ? its posible that windows could have installed a driver that wasnt designed for your chipset goto dells webpage and get the new drivers if that dosnt work try turning down graphical acceleration Control pannel -> system -> Graphics
