3dmark ending and making my system crash

[Lestat]

ok im gunna reload 3dmark so just to let you know that im doing that

but this is the thing.

3dmark 01 03 and 05 all do this.

at the end of the benchmark when it switches back to your desktop and it should be tallying your score 1 of 2 things always happens.
1)
i will get a windows error saying that 3dmark has crashed or something similar
2)
my pc will just flat out reboot

now has there been known issues with this happening ? or is my system just that unstable ?

i can prime fine and memtest fine so i dont think its that

my videocard clock is a POSSIBLY borderline but i will drop it down 10mhz and test again.

i just really dont see any reason why it would be doing this.

anyone else seen this before ?

Put the vid card to stock speeds and run 3dmark and see what happens.

yeah do that and normally if it just exits to the desktop it means you need more voltage somewhere.
if it freezes it could be the cpu or gpu oced too much.

I had similar problems with Palit 6600 AGP - it doesn`t have power connector. On stock speed everything was smooth. IMO power system just can`t handle it or the core is OCed too high.
