Well, I just bought a bunch of new parts to upgrade my sisters computer. I got a combo deal @ the tigerdirect store of a Soyo SY-P4i 845PE board, case, and 400W PSU for $69. It is using 512MB of Corsair Value Select PC3200, a 120GB Western Digital 8MB drive (both new) and her old Radeon 32 DDR and old SB Live! The CPU is a 3.0 C Engineering Sample. I ploped it all together and installed windows on da new drive. Well, when it went to boot after finishing the install it hung when I tried to logon as a user. I tried again and it will always hang as i try to log on or right after I logged on. Well, I can boot to safemode and run Super PI all day long and it is fine. If I drop the FSB to 190 or lower it boots reguarly into windows with no problem. WTF is going on? I have messed with the AGP/PCI lock, voltages, memory timings, everything. It dosent appear that the CPU is running too hot. Why will it work fine in safe mode but not boot to regular windows? I tried reinstalling windows AGAIN and it still does the same thing. Thanks for any help!
