Replacing the motherboard

Dell Inspiron e1705

Specs: Windows XP
So from what I can tell on my laptop, it sounds like my motherboard is toast. Checked the hard drive, RAM and even the LCD (hooked it up via VGA cable and white dots appeared then went back to a black screen) since it was a black screen (with blacklight) and would not boot. How hard would it be to replace the motherboard? I've done some repairs before, hard drives and new keyboards but nothing like this.

How have you tested your ram, and hard drive? What do you mean when you say you hooked your LCD up to VGA ? The VGA port on laptops is an output not input port.You could spend the money on a replacement motherboard ( which will cost mega$$) only to find out the CPU has failed or some other component is causing your problems.

I removed the RAM and tried it in different slots to make sure it wasn't that. I purchased a new hard drive at first and tried to boot from CD to restore everything and the system only beeped twice at me. Then I purchased a VGA cable and checked the display to see if that was causing the issue. When I would start it, random white dots only appeared then quickly dissappeared and showed a black screen. Replacement motherboard is $99.

OK the ram test was not conclusive but since you did get POST beeps of some description the CPU at least still works. I suppose for $99 it might be worth trying to replace the motherboard. I've never pulled a laptop apart so cannot advise on what you might face in the process.
