Hello I recently started to have some problems with my system. It loses video signal in Windows 7 x64 genuine, Windows XP SP3 and even in BIOS (happened once). Anyway... after I reset the system it works fine for some time. After the video signal is lost I can see activity on hdd led and network adapter. It even finished writing a DVD in this "no video signal" state. I want to quote that this happens kinda' random .. in 3D games, on desktop while in idle state. I realized that sound gets stuck too. My system is based on an Intel DX48BT2 mobo, 2GB DDR3@1066MHz, nVidia Geforce 9800GTX+, a q9450 Intel CPU and 600W Corsair power supply. I keep all components at stock speeds (no OC). After restart, Win 7 gives me this analysis message: Additional information about the problem: BCCode: 116 BCP1: FFFFFA8001E38010 BCP2: FFFFF880049B8220 BCP3: FFFFFFFFC00000B5 BCP4: 000000000000000A OS Version: 6_1_7600 Service Pack: 0_0 Product: 256_1 Files that help describe the problem: C:\Windows\Minidump\102809-22323-01.dmp C:\Users\marcelcore\AppData\Local\Temp\WER-43274-0.sysdata.xml If anyone can tell me what this error means maybe it will help me choose the right component so I can send it back for warranty, if it's a hardware issue. I also attached a zip with a dump file generated after reboot. Thanks in advance !
