There seems to be like 3-4 different themes going on at the same time. The logo and the header look very technological, clean and hip, although the nav bar above it doesn't match it at all, probably because of the fonts.
The silver box doesn't fit well in the blue background section which looks very primitive itself.
The orange boxes grab the attention, but the white outline on the font shouldn't be gradiated. Should just be a bold white outline. Everything else is clean and crisp, that should be too. But the orange is not the right shade or not the right colour.
For what you're doing, maybe a style like
www.hp.com could work well for you. Different colours than what they use, but clean lines, very clear.
