First of all I can't tell you how many things I've tried getting my computer at least to install windows. Let me start by saying that COMP-USA doesn't help for crap unless you give them your life (and 100$ to cover if your life isn't covered by a money back guarentee). The first problem I have and willl probably have is the HARD ERROR: C0000221 problem before windows installs. Its been said that its most likely a RAM problem. Not in this case. I've tried 4 different brands of ram and thus far I've been told to stick with CORSAIR 512MB. The next thing is the NTLDR is missing - Press CTRL+ALT+DEL to continue. I'm using the overpraised Lanparty Sli-d. On startup the memory controller's IRQ is N/A?? BTW I put two 512's in my other Gateway and it's running sweeter than ever . Whats the dillio?
