Bsplayer may have ruined my system

[Uti]

My system :
Windows 2000 Sp3
Piv 2.0 Ghz / 512 Mb
MSI 645 Max / Radeon Prophet 8500 FDX
Directx 8

I was playing some personal divx 4 an 5 files with Bsplayer from a CDRom with 1.0.0.803 version.
I paused the image to answer the pjone and when I tried to play it again 'with space bar' I got a system reset. Monitor displayed "Frequency over range" message.

At restart ATI message error which was sent to ATI. And I was suprised to see all my NTFS partition not accessible from windows.

At this point I thought it was a virus or something but I have Mc Afee running. I installed another AV program and Ad-aware => nothing to declare.

Then I conclude for a driver or hardware problem from my graphic card.
I switch it with a AC770 viper => same problem.

I updated mobo drivers, SiS AGP drivers, SiS IDE drivers and Windows 2000 Sp4, direct x 9.0b and all patches from microsoft !!!!

Memtest error => 0 errors in 2 passes.

I still have trouble today with 2 different GC.
If I pause any movie with BsPlayer and close program => system reset.

The point is I don't really know if my problem is linked with the program but I know everything started from it.

Regards.
