So it seems likely there's some issue with the analog video signal -- it's out of spec as far as what the monitor can handle, or the monitor needs to be manually adjusted. It's been a while since I messed with fine-tuning VGA, and I know I've never done it with a Sandy Bridge IGP, so I don't know what options are available in your display settings for the analog output. But if it's trying to drive the monitor at a refresh rate it doesn't like (for example), you could see the symptoms you describe.
(There's a chance it's your no-name PSU -- cheap PSU + analog signals might produce this kind of problem once the video driver is pushing things hard, but I'd look into the display settings first)

Not sure about the newest stuff, but I know my CULV-based laptop has a separate Intel graphics utility that likes to live down in the system tray. Haven't had any problems with it, but several years ago I did fight several times with an ATi driver that would override the Windows refresh rate preference with a custom driver setting that was buried deep in ATi Submenu 17, just above the earth's core. It was quite maddening to chase that one out, because you could set the Windows refresh rate to whatever you wanted, and it would indicate that the new setting was active, but the display was stuck at 60Hz regardless.
