I built my brother a pretty decent machine. Altogether here are the specs. Monitor: Acer AL1916WABD 19" Widescreen LCD Monitor - 5ms, 700:1, WXGA+ 1440x900, DVI, VGA, Black CPU: AMD Athlon 64 X2 5600+ Processor ADO5600DOBOX - 2.90GHz, 1MB Cache, 1000MHz (2000 MT/s) FSB, Brisbane, Dual-Core, Retail, Socket AM2, Processor with Fan RAM: Corsair TWINX 2048MB PC6400 DDR2 800MHz E.P.P. HDD: Seagate 250GB Serial ATA w/NCQ 7200/16MB/SATA-3G Mobo: Asus M2N-SLI nForce 560 Socket AM2 Motherboard GPU: EVGA GeForce 8600 GTS 512MB PCIe w/Dual DVI CD/DVD Drive: Lite-ON 20X DVDRW SATA LH-20A1S-12 Super-Multi Int Case: Xion Solaris Black/Green Clear Side Case 450W PSU I'm using the PSU that came with the case, and it's +12V is 18A. The problem is, when I boot the PC, the monitor won't boot with it. I've converted it to another monitor as well. I've tried using the DVI on the Acer Monitor, but it says that it requires DVI-D, and the 8600 supports DVI-I. So, trying that didn't work. I tried the VGA adapter on the Acer monitor, because it also has a VGA cable. That didn't work either. When I switched it over to another monitor, That I know works, it did the same thing with a VGA > DVI converter. Monitor goes to sleep immediately after recognizing that the cable is no longer disconnected. It states: Cable Not Connected, and when I plug it in, that goes away and it goes to sleep mode. Any help? Thanks.
