|In addition to being fired up about fixing this problem, you need to have a defined plan of action. At this time, I'm not even sure what disc you are on a search for - XP or Vista. While I assume that your Satellite A135 came pre-installed with Vista Home Basic (32-bit), your OP also lists the OS on the machine as XP -- which one is it?|
Assuming you have Vista, I can only hope you are contemplating doing a Repair Install with the disc you are looking for so as not to lose data. However, I don't know how you intend to get your hands on a Retail Home Basic disc because the machine never came with a System disc & if you were to order a replacement, what you are getting isn't going to be an OS disc but a Recovery media & you sure can't use that for a Repair Install of your machine, unless your plan is to restore the machine to factory-state.
If that is your plan, you don't particularly need a disc for that. Your machine was preconfigured with a recovery partition in case you ever need to restore the machine to its factory-state doing the course of your ownership. Just so you know, this is going to wipe the machine clean & it is advised to backup any critical data you might have on it before embarking on the recovery process.
Your manual should have the instructions needed for a complete recovery. But, you can also find PDF information related to the exercise here & here & here if your manual isn't at hand.
BTW: Did you ever try "Last Known Good Configuration" from the advanced startup menu at all?
