Ramdomly stop and error

[trixxie]

Hello,
First of all I want to thanks Atom for his hard work!
I will try to explain as best as possible what is the problem:
I use a .bat file for SL3 unlocking, prepared by my self, for program every 10% of the cracking process like a chain in this way:

Code:

........
:ascen
Hashcat.exe %hash%:00%imei%00 -1 00010203040506070809 -2 00 -m 1900 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?2 --pw-min=15 --pw-max=15 -n 400 --hex-charset --hex-salt --restore-timer 60 --outfile-format=1 --outfile=%imei%.txt
if exist %imei%.txt goto capymail
:asc1
Hashcat.exe %hash%:00%imei%00 -1 00010203040506070809 -2 01 -m 1900 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?2 --pw-min=15 --pw-max=15 -n 400 --hex-charset --hex-salt --restore-timer 60 --outfile-format=1 --outfile=%imei%.txt
if exist %imei%.txt goto capymail
:asc2
Hashcat.exe %hash%:00%imei%00 -1 00010203040506070809 -2 02 -m 1900 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?2 --pw-min=15 --pw-max=15 -n 400 --hex-charset --hex-salt --restore-timer 60 --outfile-format=1 --outfile=%imei%.txt
if exist %imei%.txt goto capymail
:asc3
Hashcat.exe %hash%:00%imei%00 -1 00010203040506070809 -2 03 -m 1900 ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?2 --pw-min=15 --pw-max=15 -n 400 --hex-charset --hex-salt --restore-timer 60 --outfile-format=1 --outfile=%imei%.txt
if exist %imei%.txt goto capymail
........

as you can see if code is found it jump to section "capymail" that capture screen (for checking pourpuse) and send an email to my mobile phone informing that a job has finished.

The problem is that ramdomly when start a new command of hashcat, for example it start first 10% and finish without find the code, the .bat keep running, doesn´t find the txt generated by hashcat and start the next 10%, then it just stop working showing 14%-16% of gpu usage and low temperature. If I quit then and reestart the job it makes a bluescreen win error and freeze, I must to quit job, restart win and start the job again.

Things you may need to know:
CPU: i5 3.2ghz
RAM: 4gb
GPU: 2 x 5970
PSU: 2 x 600W
Win7 Ult. 64b up to date.
Catalyst 11.11
MSI afterburner set to 800Mhz gpu / 1000Mhz for memory
The CPU is not connected to nothing but network, has a dvi dongle in the first GPU and I use it by TeamViewer allways.
There is nothing special installed, only OS and Security Essential as Antivirus.


ANY ADVICE WELLCOME!!!
Thx and BR
