Does it do this right after windows tries to load? Do you get the initial bios startup and then it goes into power saver when windows loads?
I'm not saying the cable is bad...I'm thinking the monitor or the vga port on the monitor may be bad. If it's the monitor, there's nothing you can do other than replace it. If there are other outputs on the monitor...such as dvi, you could try to hook it up through the dvi port to see if that works...hooking it up through dvi would require a dvi cable as well as your video card having a dvi port.
The only other reason, aside from hardware failure that your monitor would behave this way is if you set the resolution on your computer too high beyond the capabilities of the monitor. But if this were the case, you would see the bios messages before the monitor went blank.
Yes...it's a different type of port ... a little wider. Sounds like you have an older monitor if it doesn't have a DVI port.
Since you also tried connecting this to another computer system, it's highly likely that the monitor is dead.
