Hi. Today I got a brand new Acer pc. Model: Aspire x17000 I started it up earlier today. Worked great! I downloaded a couple programs and then i downloaded World of Warcraft and its expansions. I was playing for a few minutes and then i hear the speakers repeating the same sound over and over. So i turn off the sound then my pc freezes. Ctrl-alt-delete didnt work. i manually restart my pc and i get an error message. at start up it says Entering Setup. . . Memory Clock: 800MHz, Single CHannel Mode NVMM ROM version :4.083.14 Initializing USB controllers . . Done. 4096MB OK USB Device(s): 1 keyboard, 1 mouse, 2 storage devices Auto-Detectiong 3rd master . . SATA Hard Disk Auto-Detecting 4th Master . . ATAPI CDROM 4th master : ATAPI DVD A DH16A6S YA16 Ultra DMA mode-5 Auto-Detecting USB mass storage Devices . . Device #01 : Generic- Compact *HiSpeed* Device #02 : Generic- SM/xD/SD/MMC/ *HiSpeed* 02 USB mass storage devices found and configured 3rd Master Hard disk error Press F1 to Resume The main part of this is the 3rd master hard disk error. After pressing F1 i got to a screen that tells me to "Reboot and Select proper Boot Device or insert boot media in selected boot device and press a key." by pressing a key the message just repeats. now the next thing i did i went into my bios settings at start up and saw that it said that my first 2 devices were detected but my third device was not. This device not being detected is causing the problem i assume? What caused this and what can i do about it? Please respond soon.
