The year-2000 bug will cost governments and corporations billions of dollars to remedy, but it need not cost you anything to fix it on your home computer. That's the good news--your late-night solitaire games are safe! The bad news is, you'll still have to pay a cost--in time spent poking through too many tech-support Web sites.

For those of you that have been in a sensory depravation chamber for the past few months, the millennium bug can occur as the real-time clock in PCs rolls over from 11:59 p.m. to midnight on New Year's Eve. (The Mac OS is immune to this problem, but many Mac programs aren't.) Windows computers using the "short date format," in which the two digits are used to represent the year, will see dates following 01/01/00 as 1980 instead of 2000. (Windows assumes that it couldn't possibly be running any earlier than four years before it debuted; on other computers, 01/01/00 may be interpreted as Jan. 1, 1900.) Many applications may not know what to do when they receive this puzzling date information from the rest of the computer; errant calculations, misleading feedback and outright crashes can result.

A home user has different options at hand to squash the Y2K bug. Depending on where you shop, some of them can cost a fair amount of money--but unless you're running some program that your life, or your bank balance, depends on, keep the credit cards holstered. There are enough free options out there.

One (possibly heretical) option is to do nothing. If the computer is only used to run Minesweeper and write a letter a week to Grandma, the computer's perception of the date is its own problem, not yours. In other cases, though, this approach becomes a gamble. Even on a modern system, date-sensitive programs, such as e-mail or personal-finance software, might fail.

A second option is to reset the system clock on New Year's Day, then compute as before. This should work in many cases, but you should make sure that the computer doesn't revert back to 1980 when you turn it off.

A third approach is to test your system ahead of time. NSTL, a software-testing laboratory, publishes YMark2000, a widely recommended, free utility to test PCs for Y2K bugs; visit to download it. Numerous Y2K test-and-fix programs are on sale as well, and the popular utility suites all bundle some sort of Y2K tools of their own.

If you detect a problem with any of these tools, check with your PC's manufacturer before buying any repair program. In most cases, you should be able to download or order a utility that will fix the problem by updating the machine's BIOS, or Basic Input Output System. The BIOS chip, the first thing a computer activates when you turn it on, prepares the system for further operation by looking through its own tiny stash of memory for such system-wide parameters as the date.

Below, we list year-2000 compatibility information for a variety of hardware and software manufacturers.

In most cases, a download or a small repair utility should fix the problem, keeping your Solitaire game safe for all eternity.
