I have the same problem with an ASUS EeePC, tho' it has the dual core CPU it only has 1 GB RAM - with W7 Starter. Totally frustrating, hit a key then go and make a cup of coffee.
My Man Wot Does obtained extra RAM then found that he couldn't fit it, and a call to ASUS confirmed not upgradeable. I guess that's why it was so cheap.
I feel an iPad coming on.
