First off, the BAD_SYSTEM_CONFIG_INFO error is caused by faults in your computer’s registry.
In this case, however, the damage done is severe. There are three possible problems: faulty memory (RAM), a faulty hard drive, or a program that’s damaged your registry.
To test the former, remove your RAM sticks and leave only one in, testing which stick won’t let your system boot. If none of them are the source of the problem, it’s not a RAM issue — and if you don’t know how to do this, get a technician.
