HI, I have an old motherboard ... Base Board Information Manufacturer: Gigabyte Technology Co., Ltd. Product Name: M61PME-S2P Version: x.x Serial Number: Processor Information Socket Designation: Socket M2 Type: Central Processor Family: Athlon Manufacturer: AMD ID: B2 0F 06 00 FF FB 8B 17 Signature: Family 15, Model 107, Stepping 2 00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) ... and since I've upgraded from debian 7 wheezy to debian 8 jessie (reinstalled, actually) I've been experiencing a grey screen of death, at unpredictable intervals ... usually associated (I think) with using iceweasel or icedove. The screen goes grey and the whole machine is locked up tight. I have to powerdown and power back up. Just like a microsoft box. I don't like this at all. Has anyone else had this problem? Any and all help greatly appreciated. Never any problem with wheezy or unbuntu 8 - 11 before now.
