Possibly damaged RAM slot

Hi guys, hoping someone can help me with this.

I bought a new desktop off of Trademe (New Zealand's Ebay) about a month ago and have had no problems with it other than issues with the graphics card that I installed. I bought a second hand gtx 560ti which seemed to work fine but would crash anytime I played minecraft and would throttle seriously anytime it put any strain on it. Eventually it started playing up, artifacting on the desktop and blue screening the computer or just completely crashing to off. I stopped using it but left it in the machine switching to onboard graphics, which worked fine but would result in a bsod on shutdown which required a restart then the second shutdown would have no issues.

Just before New Year I decided to remove the gpu to see if this would solve the problem. I totally forgot about the lock holding the GPU in the mother board and pulled a little bit noticing a slight bend in the motherboard before I realised I needed to release it to get the GPU out. The machine started up no problems after this and went straight into windows. I thought i would shut it down to check whether it had solved the blue screen problem and it had, no blue screen. However after shutting down it would not restart. The fans would switch on but no boot screen or keyboard lights (numpad, capslock etc.) would light up. The fans would ramp up and down but nothing would happen. Occasionally after a couple of mins it would get to the splash screen, then the dual bios screen then switch off and start again.

I removed every bit piece by piece and replaced it except for the RAM. Nothing. Finally I switched the two RAM sticks into each others slots; only two slots so not much choice, nothing. I removed one stick and it booted fine. I ran a memory check through windows and no problems. I put the other stick back in and it worked fine. I restarted several times no problems.

I came to switch it on the next morning and no boot. Until I remove one RAM stick boot up, shutdown and replace the second stick. This has happened for the last five or so days. Once it has booted up there is no problem with restarts or shutdowns until the next day then I have to remove and replace the RAM for it to start up.

Any ideas?

tldr; after removing GPU computer will only switch on first time if it has only one stick of RAM after that it will be fine with two.
