So basically I have my gaming PC in a case from IBuyPower. It is a midsized tower, but I think I can do better, so I am moving the computer to a full sized tower that holds many more fans, and supports large liquid cooling systems (it's designed for nothing but cooling and awesomeness). Anyways, I'm one of those people who are very tech-savy, but for some reason I'm just very nervous about moving the stuff over. I know physically everything will fit in the full case. What I am just worried about is that I'll move everything over, plug in everything exactly as it was plugged in whilest in the old case, etc., and then press the power button only to see a blank screen (obviously with the right switches and things hooked up). The reason I'm nervous is one time I turned off my PSU, and pressed the computer power button to drain power out of the motherboard so I could add fans to the case without getting shocked. Well, I ended up having to go somewhere over the weekend so I left the computer (PSU off and such) over the weekend. I come back, turn things on, and I get this EZ flash thing that comes up. After that computer restarts, but nothing but a blank screen came up which was something with the BIOS that I couldn't get fixed.
Basically I'm asking two questions before swapping PC cases:
1. Any opinions as to what may have happened with that old PC that I left with the PSU off for a weekend?
2. Any things to do to make sure the PC starts once moved into its new case?
I'm 16 so 1300 I spent on my PC is a lot more to me than a lot of other people spending that for a computer, and I know what I am doing with moving stuff over, but it's just those mystery things that happen where for a totally unknown reason things don't work.
