First post here, and hopefully one of many in the coming future.
Recently I bought a new GPU (GTX 780), more RAM (2 G.Skill 2GB ea), and a new tower (Zalman Z11 Mid-tower )
So before I start, I just want to mention that one of the RAM sticks I had previously was corrupt, so instead of installing that in the new system, I left it out since I was planning on returning it. So I'd have 6GB installed, as opposed to the 8. Also, both sets have the same serial numbers, except the last two letters after "4GB". Also, the new ones I bought were red, while my previous ones are blue. I'm not sure if that has anything to do with the PC not starting up but I just figured I'd include it in here.
So this tower has a lot more fans than my previous one. I really like it, however there are some issues I came across when putting it together. The main one really is the front part. It was required to remove it in order to reach to install the CD/DVD drives. Which isn't a problem, but one of the hooks that you grip onto to remove, broke off. It doesn't inhibit anything, it was really just there for decoration honestly. But, when I attempted to put the cover back on, I wasn't able to fully. There are small holes on the tower itself where you attach the cover to (there are 3 sets of them). So I tried putting them all in, but I was only able to click the bottom and middle one, the top wasn't going in fully. Even when I try putting in top first, it doesn't go in. There are two small cables that you must connect from the main tower to the front cover, because of the lights and more importantly, the On/Off switch, which I was able to do without a problem.
So when I plug in everything, turn the PSU switch on, I try clicking on the tower button, and of course, nothing turns on. However, my room light flickers, and I hear a faint click, but really isn't much of a click. When I try turning it on again, I don't hear/see what I did before, unless I turn everything off and try it again. (kinda spooky especially when the phone rings as you try turning it on the first time)
So my thinking is it's obviously something to do with the PSU. Although it's fairly new, and is a 750w. And I checked multiple times with the cables, and everything is plugged in. I did a few times swap out some PSU cables I had to use for my old GPU, and replaced them with other cables that were needed for my new GPU. (these cables came with the PSU itself). I also had to use more cables that were included with the PSU to install all the additional fans.
Perhaps 750w isn't enough? Anything you can think of would be so helpful.
