Hey All, I am not sure if this is the right forum to post this in, so if it is not my apologies. I think I'll list the parts that my brother bought for hiS PC: Gigabyte GA-8I945G Pro Socket 775 Intel 945G Intel Pentium 4 506 Sapphire ATI Radeon X1600 Pro 512MB DDR2 Corsair DDR2 PC2-5400 Case Now here is the problem...After I have put everything together, I go and power up the PC and to boots up like everything working but... 1. CPU fan at boot up starts spinning really fast, than it starts to slow down (the noise it makes is no longer loud...). 2. PC just freezes up at the very first boot up screen (the one that shows you how to get into the bios setup). 3. Keyboard and CD-ROM not fuctioning. I really have no clue what the problem might be, I did some research using google and varies search engine and some of the places I found mentioned it could be a problem with the RAM. Any help would be much appreciated .
