Overloading GPU error -06031 on Pro Tools HD10

Hello,



I am receiving very often this error:



'Overloading CPU. Check for compatible disk drivers, and try the following: Remove native plugins, increase "HW Buffer size" in the Playback engine dialog or thin automation. (-6031)



my current session consists of 14 Audio tracks in 24/48 without any plugins or automation made.



The installed DPC Latency Checker says current latency 88 ms and absolute max Latency 178 ms



on the playback engine dialog buffer size 1024 Samples

host processors 4

Cpu Usage limit 95%

96 voives 3(dsp's)

delay compensation Long

On the system usage window

Pci 13%

Cpu Native 0% (no plugins loaded yet)

Cpu Clip 0%

Disk 0%

Disk cache 23%

My PC system consists of



pro tools HD3 Accel PCie (v.10.3.8)

Mytek 8x192 converter with internal Protools card, both firmware chips up to date

Windows 7 64 Ultimate

Mb Asus Z87 Deluxe with internal GPU Intel HD 4600

System Drive OCZ Agility3 128 Gb

2 Data drives WDC WD1001FALS-00J7B

On the Digitest, the PCIE card #1 doesn't pass successfully, the failure is Digital loopback test failed. Everything else on the digitest seems ok.



Any help??



Thanks
