This should help with the usable ram http://www.sevenforums.com/tutorials/66482-memory-set-maximum-amount-used-windows-7-a.html
This with changing IDE to ACHI http://support.microsoft.com/kb/922976
The Vram I do not know anything about but should be explained in your manual.

for the error of only 3.2g of ram showing...you installed windows 32 bit os. it stops at that size of ram. you need to install windows 64 bit. if you have the retail version of windows 7 there should be a 64 bit cd in the kit. if not call up microsoft they will give you a 64 bit oem number and a link to download the 64 bit os iso. with that you can burn the cd or put it on a 4 gig usb stick.
2. for the drive crash you have to put the drive into achi mode before you install the os. if done afterwards it going to crash. you can sometime get windows to load right if you go into safe mode. windows may then load the drivers it need to boot in achi mode.
3. for the video ram issue it not a typo look under your owners guild the give you a warning option #5.
The maximum shared memory size is defined by the chipset vendor and
is subject to change. Please check Intel® website for the latest information
intel max spec is 1.7 but the vendor limits the video ram to the size you see.
