White squares on my monitor?

Samsung monitor won't display at its native resolution with on-board Intel graphics card. Help?

• The monitor is a 20" Samsung SyncMaster 2043SWX, and the graphics card is an Intel 82865G Graphics Controller. I've already installed all the drivers for the new monitor and tried updating the drivers for the graphics card, but it says there are no updates. The native resolution of the monitor is 1600x900 at 60Hz, but the display menu gives no option for that resolution, nor any other 16:9 resolution. The only decent-ish looking one I've found is 1440x900 at 75Hz, and it refuses to let me change the resolution to anything at 60Hz that isn't completely stretched out or squished. The graphics card information reports that it DOES support 1600x900 at 60Hz, but the option isn't given to actually change it to this resolution and refresh rate. The instructions that came with the monitor are not very helpful... at all. The auto adjust button does make things slightly sharper, but it's still the same resolution of 1440x900. Squares are not square, they are elongated horizontally. Further, every single time the monitor resets, the menu pops up to remind me that the optimal resolution is 1600x900 at 60Hz, as if I could have possibly forgotten this despite all the crap it makes me go through to get it there. I have to press the menu button on the monitor to make this message go away; it doesn't disappear after five seconds like it does when I pull up the menu myself. I'm thinking this message will keep coming up until I fix the resolution issue. I've even tried PowerStrip, which is supposed to let me force a custom resolution, but the resolution I tell it I want won't show up after restart. Any other ideas?

• Answer:

  The Intel 82865G chipset is quite an old one. Intel stopped supporting it in Sept. 2007. In its original design, it supported non-widescreen format resolution. It is very likely that 1600x900 @60Hz is not supported. If PC has a graphics expansion slot, install a more recent graphics card. If you do not plan any gaming, you could also consider a PCI graphics card.
