GaaaaH! YOU beat me to it, Lululee! NICE first time render- it took me a while to figure out the lighting with HDRI. As nhirschberger said, the dome light adjust is your best primary control. The second is the color of the light itself- I've found that by introducing a browner tone (red-yellow-dark mix) that you can get a look that better matches Poser's own default lighting setup-- and which most Poser babe skin is designed for. Both Vue (and Bryce) tend to default to a "Blue-er" main light- which is generally fine for scenic work, but not interiors with Poser Babe skin. And, yes, the other main thing to tweak is to look at her mats in the Material Summary and then go in and maybe adjust the skin using the Advanced Material Editor--- go all the way over to EFFECTS and adjust down the Diffuse and maybe Ambient settings- just a bit-- BUT only do these AFTER you have set your main dome light controls and the main light color- so it becomes a final bit of tweaking... On your computer issues- I am puzzled- I have used Vue 5 on my Athlon 64 and my older P-III with only 512MB ram and have not had any problems with Vue 5. My first GUESS always is that your graphics card driver is not current?
