bizarrely enough, using the same hardware for mining LTC is working fine with CGMINER...

i assume that there is something i need to fix?

if it makes any difference i am running Microsoft Security Essentials as my AV and i have UAC disabled.

Nothing bizarre.  BTC works best with one SDK/Driver combo and LTC with another.  You just need to decide which coin you want to mine with that rig.

Q: Which AMD SDK is the best for cgminer?
A: At the moment, versions 2.4 and 2.5 work the best for R5xxx and R6xxx GPUS.
SDK 2.6 or 2.7 works best for R7xxx. SDK 2.8 is known to have many problems.
If you are need to use the 2.6+ SDK or R7xxx or later, the phatk kernel will
perform poorly, while the diablo or my custom modified poclbm kernel are
optimised for it.

Q: Which AMD driver is the best?
A: Unfortunately AMD has a history of having quite a few releases with issues
when it comes to mining, either in terms of breaking mining, increasing CPU
usage or very low hashrates. Only experimentation can tell you for sure, but
some good releases were 11.6, 11.12, 12.4 and 12.8. Note that older cards may
not work with the newer drivers.

Hi guys,

my mining PC is also my gaming rig, it started crashing when watching youtube videos and i noticed that the driver was old so i upgraded to the newest 13.4 but now my miner (50miner and CGminer) will not run.

PC:
Q6600, HD5870 and HD5850.

Any suggestions on what to do?

running Windows 7.

I've uninstalled the drivers and software, run driversweeper and manually installed the gfx drivers again...
