Same issue here. Brand new HP computer with:
Win 7 64-bit
1GB DDR3 NVIDIA GeForce 405
6GB DDR3-1333MHz SDRAM
1TB 7200 rpm SATA 3Gb/s hard drive
Intel(R) Core(TM) i5-2300 quad-core processor [2.8GHz, 6MB cache]
300 Watt PSU
HP Customer Service tried some troubleshooting such as updating latest display driver, and system recovery. They said the PSU might be too low because I added an extra internal hard drive and an extra stick of RAM.
I removed my second internal hard drive and the extra stick of RAM and after one day of use so far, no display driver error. I'm hoping it IS my PSU which means I'd have to get a stronger PSU, but then again I'll be disappointed knowing this computer under
the "High Performance" category on HP's website can't handle a second internal hard drive and an extra stick of RAM.
Does anyone know if 300watts is not enough for two internal HDD's?
