Restart Guiminer Scrypt Remotely?

[Draxus]

So I am using Guiminer scrypt to mine litecoins.  It runs great and after a couple of hours or overnight it my hash rate will get real low or will stop alltogether.  As soon as I hit stop/start I go right back to my 540khash/sec rating (Sapphire 7950).  Is there anyway to just make it stop and start like every two hours to avoid this?

You can use Cgminer or you can write a script in autohotkey, which would press stop/start after some time interval.

Your card might actually be crashing.  Try turning up the voltage or turning down the clocks.

I think you might be right.  I noticed it said AMD Video driver stopped working, and when I just got back from the shower the whole computer crashed.

I am using the 7950 High usage configuration. 

Like I said I bought  sapphire card and it is clocked like this out of the box:

GPU Clock: 925
Memory Clock: 1250
VDDC: 1250

I maintain in the 60/70celcius range but I have had it crash...thoughts?
