I'm in a bit of a dilemma here. Let me start off with the beginning. I have 2 computers, both with Windows 7 Ultimate 32 bit. Computer 1 had this - Biostar TF570SLI, Athlon 64 X2 4800+, sata Samsung 250GB HD (Win7), sata 1000GB HD, ide 180GB HD (didn't use). Used Hazar's Loader. Computer 2 had this - ASUS M4N72-E 750a SLI, Athlon X2 7850, sata Western Digital 250GB HD (Win7). Daz's Loader. Being the idiot that I am, I moved the parts around. Computer 1 became this - ASUS M4N72-E 750a SLI, Athlon X2 7850, sata , sata Samsung 250GB HD (Win7), sata 1000GB HD, sata Western Digital 250GB HD. Computer 2 became this - Biostar TF570SLI, Athlon 64 X2 4800+, ide 180GB HD So I pretty much swapped the mb, processor and 180gb for the 250. Now here's where the problems start. Now computer 1 is able to boot up but detects the hardware really slow. It auto-detects the 250GB HD but isn't able to boot up. It gives me an error during the hardware loading and it doesn't get detected anymore once I enter BIOS. I believe it's still there because every time I enter SATA3, it lags as if it's trying hard to detect it. Everything else seems fine so far. Now computer 2 like computer 1 is detecting the hardware really slow. It detects the IDE 180GB HD so I'm like okay I'll just install Win7 via USB on it. I go through all the windows installation up until the last part where it requires me to restart the computer. When the computer gets restarted, it goes through the whole windows installation all over again. I changed the boot sequence with HD first, didn't work. Tried removing the USB and let it boot up, doesn't detect an OS. Somebody help? Edit- Just unplugged the 250GB HD on SATA3 and everything is running smoothly. Back to 10 second startups.
