computer crashes when running ocHashcat 1.31
#1
First of all hello for all members and sorry for my bad english.
In the last days i wold like to run oclhashcat 1.31 but after some times the process stopped to working. about after 20-30-40 mins.
The computers fans still spinning after process stopping , just the screen goes.And i must press everytime the reset switch on the front panel.
The graphic would be cold after the crash just the fans spinning.

i have a Intel Core2Extreme with 3x3Ghz on a Asus P5E with x38 chipset
Graphic card is a Ati Antilles Radeon 6990 with an Artic cooling Twin turbo
And a 780W psu.Win7 x64 with 8 gb ram ddr2 800 Mhz
When i play games or makestresstests or bernchmarking i vever seen more Temp on the gpu then 65-70 Celsius
And runs all sable.
But with oclhashcat after some time the screen goes and the process sopping to work.
The cooler had i since 3 days mounted. Before the card has 80-90-95 celsius too.Now it is cool i think.
Have anybody any suggestion what can the problem causes?
