Hi guys, Lately my computer has been through a lot and I've now hit another snag in my effort to get my computer back to normal. So a little background information for you all; Beer spilt into computer, so I replaced my mother and GPU with working components (New Asus Z77 Deluxe V and a second hand working GTX 275). Since then I cleaned and rebuilt my computer, that night as I was trying to reinstall Windows 7 Professional 64bit I had problems with getting my screen to show up, and after rebooting a few times it decided to give me a bios screen and I installed windows successfully. For the week running up to today the computer booted fine every time and I have had no issues. For some reason this morning, I cannot get a display but I can hear it booting up to windows login screen, and I can type in my password and press enter and login in (with no screen) and then ALT+F4 and shut down fine, and I've repeated this process in hope for something to change again like it did when I was first installing Windows 7. The thing I find really really odd, is that It wont even show up the Bios screen, the screen is completely black for the whole booting/post process. I haven't tried any hardware swapping just yet (as I haven't had time today due a full day at University), but I guess the main thing I wanted to ask you guys, Has anyone had any experience with this sort of Issue? or seen any other forum posts around with a similar problem? Ill start some debugging process' once I get home in a couple hours. Thanks Guys!
