To start with...take all of the following with a grain of salt...I do a lot of guessing
Worth reading, IMO: http://www.vistaheads.com/forums/windows-v...pi-driver.html.
Info on ACPI driver, http://www.osronline.com/ddkx/kmarch/pwrmgmt_8nmv.htm
I have no idea what EL might be...maybe "Intel" but that's a wild guess. It appears that your system has an Intel chipset, BIOS, etc.
Summary edited info on 9E STOP error follows, per http://carrona.org/bsodindx.html#0x0000009E
"STOP 0x0000009E: USER_MODE_HEALTH_MONITOR
Usual causes: Failure of critical user-mode component(s)
The USER_MODE_HEALTH_MONITOR bug check has a value of 0x0000009E. This bug check indicates that one or more critical user-mode components failed to satisfy a health check.Cause
Hardware mechanisms, such as watchdog timers, can detect that basic kernel services are not executing. However, resource starvation issues (including memory leaks, lock contention, and scheduling priority misconfiguration) can block critical user-mode components without blocking deferred procedure calls (DPCs) or draining the non-paged pool.
Kernel components can extend watchdog timer functionality to user mode by periodically monitoring critical applications. This bug check indicates that a user-mode health check failed in a way that prevents graceful shutdown.
This bug check restores critical services by restarting or enabling application failover to other servers."
As Broni stated...I would uninstall the video drivers...and then reinstall or install updated drivers. The current drivers could be damaged, replacing them won't impair the system in any manner.
The DVD drive...is nothing but a way to get data/info into the system. It relies on the system to interpret properly the signals submitted/read and perform the function of playing the files. WMP is the native program for actually playing DVDs
, but there are many others that can be used for that function. If any program/player can display/play CDs/DVDs properly...it's not a hardware problem that relates to the DVD drive.
