Problem

[Stuff9928]

In the past week, I've gotten about 4/5 blue screens pretty regularly. Once it was just from opening the Calculator. Now, when I open Mozilla Firefox, I get a message saying that Explorer has to close to protect my computer, and right after it says that Explorer experienced an error and asks if I want to send the message or not.
So, I checked HJT and there were no problems with that. Does anyone know what this is about?

You're going to need to download Memtest86. Burn it to a CD or have a Floppy ready. Then, restart the computer. Boot from the CD or floppy and let the test run. If you see ANY type of error in the error log, you have bad memory. Bad memory corrupts files being loaded on the specific location, thus, making your PC crash.
