I have a strange problem. Patient: Home built PC, Asus mobo, 3.0ghz Pentium IV Prescott, 1gb PC2700 ram, 1-120gb SATA 1.5 HD, geForce Nvidia FX5500 video card. I have the power management settings to turn the monitors off after 15 minutes and the hard drive off after 15 minutes. Occassionally, not every time, the PC just won't wake up...the screens won't come on and I'm assuming this means the machine itself has gone to sleep and is in a comma, LOL. I changed the power mgmt to "never turn hard disks off" thinking that would fix it, but it didn't. The worst part about this is a simple reboot doesn't always fix it. After this happens and I reset, it goes through POST and all that, but when it gets to the windows load screen, nothing happens...just a black screen. This can happen whether you hit reset or if you turn the PC off, then turn off the PSU and let it sit for 30 minutes. The only solution I have found is just to keep rebooting until it loads windows. Occasionally I will get a prompt to load in safe mode too, but usually I do not. Is this a hardware problem or a windows problem?
