Hey guys, I'm not the one with the direct issue here, but one of my buddies got some new parts for his computer, he's living up north in CT (I'm from GA..) and I've been trying to help him the best I can, but at this point I'm as dumb founded as he is.
Now, I'm not a very computer-oriented person, however he has some sort of "ASUS P8Z68-V" motherboard, and he bought G.Skill (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) to go along with it. He's running a nVidia GTX 460, and he bought a 600watt power supply to go along with it.
Basically, his issue is this - is DRAM Led light is Red, his computer screen won't turn on, and neither of us can figure out the issues.
If you have any directional base as to where i can find more information, or what the hell we're doing wrong, PLEASE let me know.
So they fixed it without fixing it, huh. If they charged you for the service I would go back and get them to fix it for free. I am really curious as to what they did...if all the hardware is the same I would have to guess that the problem was how the hardware was physically hooked up, specifically psu or cpu. Anyway, from your original post I am unsure as to the particular components he upgraded. When doing big upgrades it can make windows crazy. I would try booting in safe mode, also you can try the following: http://support.microsoft.com/kb/927392
Ultimately, they easiest option is probably doing a fresh install on another hard drive (if he has one).
