I installed the windows7 RC recently and first impressions were good apart from the fact that it constantly freezes and not even when running several programs,it will freeze even when its idle on the desktop!!!.I am running a dual boot system with one HDD running xp home and the other the rc windows 7,my pc is has a 3.2GHZ pentium 4 CPU ,1GB RAM and a nvidia graphics card with 256mbRAM.Maybe my pc is not high enough spec to run the W7rc however i thought it would be sufficent for me to at least get familiar with the new OS.Is anybody having the same problems or can anyone tell me what can be done to fix this or maybe i just need to upgrade with another 1GB ram!
