Alright, so I just got my new computer. And whenever I turn my computer on, it goes past the "Post Screen" and then continues to the point where it should boot. But, this is exactly what happens: This screen, also called the "Black Screen of Death" continues to blink for hours. I'm not even sure why I get this response from my computer, but what I know is that it boots when I put a random CD in the CD-ROM. Why does it only boot when I do this? It's actually becoming more of a headache to me to figure out. Even the support centre where I bought the PC from can't explain it. And trust me, these are people who knows what they are doing. I got a few more problems: Sometimes when the computer falls in "Sleep" mode, it won't turn on. Usually when you tap a key on the keyboard the PC will turn on again, but the keyboard lights only blink when I tap them... It won't even give me response when I press the power button. So it ends with me forcing a shutdown, which is kinda sad when I think how "young" the PC and hardware is. Another thing, when I open up a program called "Speccy" to monitor the temperatures of the hardware. It says my Motherboard (Sabertooth P67) is 128 degrees hot. I know for sure that the board isn't 128 degrees, but it's still causing me to scratch my head. + I had this little incident when I was playing Battlefield 3. While I was one of the more advanced maps, it suddenly looked like my screen turned green. Or more like a green screen with lowered opacity, cause I could see through the green. But the "Green" I saw only lasted for a couple of milliseconds, and each one of them came like 2 or 3 seconds after each other on a time period of 1 minute or so. This happened a few times while I was scoping in, but after playing for some hours I didn't experience the "Green" thing. Further information: I troubleshooted this on Google just to be sure, and I ended up with "Corrupted Windows 7" files, and that I should try to re-install my OS. But for some weird reason, the computer won't let me boot from my Windows 7 disk when I'm still in Post Screen area... The only way to run the CD is to do it while I'm in my OS. But for some weird reason it won't let me install Windows 7 again. I know there are some geniuses out there that are able to help me. I'm really concerned about the condition of my PC, as I spent $2,000+ on this machine.
