PC restarts when ALT-TAB pressed too much

Im running WinXP home.i got this funny problem that when alt-tab is pressed too much in a short time(like pressing 3 times in one second)the pc simply reboots.this occurs regardless of what im doing when pressing alttab rapidly,in fullscreen games or just surfing the net.i checked the system bios,nothing's related to this problem and it only surfaced recently.i didnt upgrade any hardware or install any new drivers.

Oh,and one more question.howcome my com reads the diskette drive everynow and then,especially when switching from fullscreen programs(games,video,screensavers etc.)to desktop and back...although when it reads the diskette drive the com does not slow down or whatsoever even if theres a diskette in it.this occurs since the first day when i brought this computer.Other than this problem,the diskette drive works perfectly,when i use it to read/write diskettes.
