My question is what is this? I bought a new Compaq Presario 2.8G P4 Laptop last week. It has XP Home on it. This morning when I went to turn on the laptop, it didn't turn on. The AC adapter was plugged in. Switched outlets. Both outlets had been working fine. Adapter cable is like new. Nothing spilled on the computer. Didn't have time to fiddle more with the laptop, but it wouldn't turn on at all. No lights. Nothing. Laptop was not dropped or anything.

Anyway, later this morning, my husband said it did turn on and he got a blue screen and it said, "UNMOUNTABLE BOOT_VOLUME" and had some other instructions with it.

What is this? The laptop is only a week old. Is this an XP problem? a Hard drive problem? Other problem?

For those responding, please respond in easy layman's terms. I'm not savy on all the technical jargon that may exist.

Thanks,
Molly
