The problem is me getting a CMOS CHECKSUM error, My system clock in the bios is wrong, and when i try to change it, It freezes. My computer will not turn off or on properly due to this i have to unplug...

Your CMOS battery may be bad. This battery is an inexpensive 3.0 Volt battery mounted on your motherboard. You could buy one at a local computer store and install it but there's a lot more involved than just replacing the battery.

I reccommend that you have it replaced by a PC technician, as after he replaces it he will have to go into CMOS setup and set all the BIOS parameters. These settings must be correct in order for your motherboard and operating system to know what devices you have installed in your system.

Hopefully this will solve your problem.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps

My Dell 5000e unexpectidly turns itself off.

There are a few things this could be, most of them are motherboard related, but there could be a cooling issue or a power supply issue. Check the BIOS log for "thermal events". Things like CPU overheating can cause weird reactions in the machine, called System hysteresis. Basically, the computer goes crazy, opening things, crashing, rebooting, etc. Based on what youve said, "restarts normally", I dont think there is a CPU issue, nor a memory issue.

The first thing I would try is replacing the power supply and remove the battery (just as a test), and see if the machine starts behaving better or exhibits the same issues.

I believe the issue you have described can be most likely resolved with a new motherboard, especially if the power supply route does not yield positive results. Bad news is, a p3 motherboard is rather hard to get, and hard to replace, and rather pricey. I would sooner consider getting another notebook pc before replacing the board.

Computer will not turn on. Possible power surge.

If the power supply is good then your motherboard must have gone bad during a surge.

If nothing was disturbed then this is usually an indication of either the power supply going bad or the hard driver going bad. I start by substituting a power supply of the same wattage or larger. If that doens't work , I change out the hard driver.  I believe that is usually a good place to start.

Won't Charge

Common fix for this problem is a simple Power Management Unit (PMU) reset. This will basically re-sync the battery "brain" to the computer so they when when to charge and when to stop. To do this, simply turn your computer off, remove battery and power cord and hold the power button down for 7-15 seconds. Then you MUST wait 15 seconds after pressing the button before applying power or inserting battery. 75% chance this will fix your problem. If Not, Replace Adapter/Charger. They have a microchip in them that can go bad that senses when to send more current to charge battery. Apple motherboards are generally better built so I'm not suspecting that at this moment. Let me know what you find out.

Onboard Lan causes boot and shut down problem

It sounds like you have some bad LAN circuity on your motherboard. You might try a workaround by installing a separate LAN card and using that. If the separate card doesn't solve the problem your motherboard is just bad and needs to be replaced.
