Okay I'm going to try to sum this up my best before I go to bed. I put a 32 bit Windows 7 RC on a CD, Try to install several times, It always freezes completly at either the inital background after I pick my language, I move the hard drive over to another machine and install windows 7 from there, it works fine. I figure its my CD Drive as its given me problems so I move it over to my main computer, BSOD on startup, yet works fine from other computer. This makes me nearly 100% sure its a hardware issue. I also realize for my ram I needed 64 bit which I just tried a few minutes ago and gives me the same effect, I have Windows XP in my PC now ATM and I'd like to move to Windows 7, I was excited to try the RC and something is not right. Some specs: Motherboard: Microstar International MS-7246 Graphics Card: Nivida GeForce GTX 285 PRocessor: Quad Core Q6600 Ram: 2 sticks of 1GB Kingston DDR2 memory Monitor: Viewsonic VA2026w Any other specs needed? Please help me out, I cant seem to find any topics similar, It only fails on my actual machine yet the installation or any windows 7 processes ( I even tried the startup repair utitlity for when it BSOD'd and that froze too ) works fine on multiple other computer I've tried it so I know its not the CD and a hardware issue or bios (Couldnt see how but wont rule it out) on my computer. Thanks for any help you guys could give me, I know were all on Microsofts Boat-O-Beta thingy.
