With a 300 watt power supply I am running these hardware items (of course, not always at once): P4 at 1.7 Ghz Intel chipset master drive slave drive 1.5" floppy zip drive CD-ROM DVD-ROM Nividia GeForce 4 4600 Creative Audigy USR Modem 768 MB of PC 800 Rambus RAM CPU Fan Side Fan Backside Fan Bottom Front Fan Onboard video Fan Is my wattage rating enough? It is a pain to change the power supply. Anyways, I have this monitor problem. I have a NEC MultiSync 19". From time to time when I play games, my monitor suffers a BSOD. Black Screen Of Death. It acts as if it goes into forceful sleep mode. All PC operation stops. There is no way to wake the monitor. A reboot is done to get back to usual operation. I have the latest drivers for my video card. Still did the same thing. Monitor BSOD from more than one game. Also, I have shut down any actions that may cause my monitor to go into sleep mode (except for BIOS in which I do not know how). Is power supply the problem? Or is my monitor going into BSOD for some other reason? Btw, this monitor has been working great since I bought it 2 years ago and is still doing great. So it may not be the monitor itself causing the problem. And it may not actually be going into sleep mode, but instead is a different version of windows crashing. But alas I truely do not know. Thank you for help. I have not the slighest idea what I can do to remedy this monitor going blank problem (wouldn't suprise me a bit if it is XP).
