Q:
 Hi, I have an Acer 4730Z laptop with VISTA system preinstalled, now I want to install XP system on it, and I’ve already formatted my system several times, which are all successful. But when my laptop starts and enters XP system disc, system stop me installing, and then I downloaded a disk cleaning tool, and set CD-ROM as the first boot device. Now when I start from XP system CD, system could load to startup interface, and then an error message shows up: stop: 0x0000007b
I guess whether system hasn’t recognized my CD-ROM? Or because I deleted some important files by mistake? Hope to get your suggestion and help. Thanks a lot!
A:
1) There’re few possibilities for this problem:
Bad thermal
Monitor, power and CPU heat much when working, so it’s quite important to keep good aeration. If monitor is overheated, it would cause color, image distortion or even shorten monitor life. Too long working time would also lead to bad thermal to power or monitor which may cause system death. CPU thermal has much to do with the laptop running stability, which is a “key factor” causing thermal failure.
Improper movement
When move laptop, great vibration would usually loosen the internal parts of the machine, finally causing bad connection and system death. So you should avoid acute vibration when move laptop.
Dust killer
Too much dust in the machine would also cause death problem. Such as floppy drive magnetic head or CD-ROM laser head covers too much dust, which may lead to reading/writing errors. Seriously, it
