I run two displays. When I got up this morning, one of them is on but black. When trying to adjust my display settings, it comes on briefly (maybe 3 seconds) and goes right back off again. System specs are as follows: Operating System Windows 7 Home Premium 64-bit SP1 CPU AMD Athlon II X2 255 45 °C Regor 45nm Technology RAM 4.00GB Dual-Channel DDR3 @ 535MHz (7-7-7-20) Motherboard eMachines EL1352 (CPU 1) 49 °C Graphics VE205 (1600x900@60Hz) VE205 (1600x900@60Hz) 256MB NVIDIA GeForce 6150SE nForce 430 (Acer Incorporated [ALI]) Storage 465GB Western Digital WDC WD50 00AAKS-22V1A SCSI Disk Device (SATA) 48 °C Optical Drives ATAPI DVD A DH16ABSH SCSI CdRom Device Audio USB Audio Device Using Sabrent USB-DH88 USB Display Adapter also I have checked all drivers and windows shows they are up to date. Both displays were fine as of about 1 AM this morning, and to my knowledge no updates or downloads were done during this time. Any help would be appreciated; I work from home and having dual monitors is almost critical.
