I have Intel Pentium Dual-Core E5200 2.5 GHz CPU (guess taht is 64 bit), 4 GB ram, 500 GB hard drive. Try to instal Windows 7. It takes about forever (~8 hours). Aftre taht, try install audio driver. It takes about half hour. I afraid instal software such as Office or Adobe's. Whats going on? Can somebody solutions?
