it sounds like your motherboard is over heating check all the capacitors on the board if any are swollen then your motherboard is becoming faulty and will have to be changed

P6STP-FL Motherboard has CMI8738 PCI 3D Audi. Drivers are available at Elite Group Web Sitehttp://www.ecs.com.tw/ECSWebSite/Downloads/Downloads_Driver_Detail.aspx?MenuID=61&LanID=9&detailid=106#Download-1

Hope this helps....

Go into the BIOS (F2). Press Alt-P until you reach "Page 4 of 7". Under "Pointing Device" change the setting from "PS/2-Touchpad" to "PS/2". Reboot.
The touchpad and point stick will still function as long as there isn't a mouse plugged into the PS/2 port. If the mouse is plugged in, it will override the integrated devices.

how fried it is

Yes you can upgrade it to 160 GIG of hard drive so just simply replace the old one and of coarse you need to install a new operating system to the new drive.....

You can download the driver for this MOBO from this link http://www.ecs.com.tw/ECSWebSite/Downloads/ProductsDetail_Download.aspx?detailid=106&DetailName=New&DetailDesc=P6STP-FL%20%20(V1.1)&CategoryID=1&MenuID=82&LanID=0

Sounds like the serial port died. I have seen that happen before. You could try a DB9 to PS/2 adapter or DB9 to USB. The DB9 to PS/2 is cheaper of the 2.

Hope this helps.

Does the system respond to boot keys (F2, F12) when the DELL logo appears? If so the problem is with Windows drivers and probably can be resolved by reinstalling or rolling back the drivers, but how? Do you have access to another keyboard? Does the system have PS/2 ports? Do you have access to a PS/2 keyboard or adapter? If boot keys work, you could also choose F8 for Last Known Good Config (XP) or System Restore (Vista).

Have you tried different ports (front if using back or visa-versa)?
Try using just keyboard or mouse to see if one has somehow shorted. Also check the ports for any sign of damage.
