When you get bad checksum, it should also offer a key to press to get into the bios. At that point you can set anything you want in the bios, and save it. After that, the machine will boot normally - as long as the bios settings are correct, and that is where your problems begin.
Clearly, getting beep codes is a problem. You need to go to the motherboard manufacturers website, find the model of motherboard you have, get the instruction book for it, and find out what the beep codes mean.
I'm sorry to say that they probably mean your new memory chips cannot work. They are probably too large, or too fast. Again the motherboard book will tell you exactly what is acceptable, so get an approved memory strip or two.
Assuming you cannot find out, then the original 128Mb will still work, but will not be enough to run XP. Windows 98 is about the limit for 128Mb in total. A better bet might be to download a very lightweight version of Linux, which should run in a small memory, and enable email, web browsing and, if you have enough room, Open Office

hey thankyou very much for the help there , would you believe having the right keyboard and mouse , and also hooking the main power to the hard drive helped it had a zip floppy in it and i took it out it must have been on a common with the hard drive , Now to pick your brains further guys , i took a lot of components out, including a silly blinkin ATX FORM CARD , 2 x usb and mouse and infared .
which now after being put back in does not work, do i need a driver to run this ? It did work , now when i insert my wireless mouse transmitter into the usb the light indicator on the transmitter works , but the mouse does not the same as my other wireless mouse and keyboard , the light indicator on the mouse stand charger thing works when i click the mouse as it always has done but the cursor stays put on the monitor , any help would be appreciated as this is how i run my network router via usb instead of ethernet, also is 190 mb of ram enuff to run xp pro ? it is installed and appears to work but will it hold long term

I don't know what an ATX FORM CARD could be... I know that ATX form factor is a computer case design specification, but that doesn't explain the PCI card. What sort of connectors does it have on the back of it?
EDIT: Oh, is it one of those backplate things with the mouse/keyboard plugs and some USB connectors? If so, it doesn't need any drivers, but it may need to be enabled in the BIOS settings on your motherboard.

lol this is silly but how do i get to bios set up? is that when a boot up after ram check it says press delete to enter set up? if so where would i find the usb to activate it , i seen one place it had usb disabled and advanced usb disaled , so i enabled but have no way of getting out of the page again , i push esc to quit so i can then f10 to save and exit but when i hit the esc it doesnt do anything

Yes, delete is the most common key to access the bios. Obviously you need USB enabled, but bios's will often not work with a USB keyboard - is that what you are using? A normal PS2 keyboard will solve that, which can be removed (returned to the loaner 
) after AN OS is completely set up, a USB keyboard attached, accepted and any required driver automatically installed. Note you have been told more than once 190Mb is not enough to run XP. I would entirely forget about wireless mice !!!

I would entirely forget about wireless mice !!!no i am using a normal ps2 keyboard , it just seems wierd that thier is power coming out of the usb port but no data , the reason i wish to enable the usb is to run my router as i are already using the ethernet on another computer , it has an option for both on the router , and also i wish to use the usb for my mp3 player , normally when you insert a a device into usb it plays a sound like da dong ga doink it does not do this , but thier is power to the mp3 player cause the indicator lights are on the player, now i will also mention that i have disabled a few items , being, Themes and also indexing services, im at a loss, where in bios do i go to enable usb ?n sorry for being a buttkiss , thanks
Hey thankyou very much guys , yay the esc key on the other keyboard was knackered , so i pluged another ps2 keyboard in and enabled the usb through bios and oh im so happy thankyou guys you guys are my heros
