Ever since I installed new ram, my computer only starts when GPU is unplugged

I received 2 sticks of Kingston HyperX 8GB (2 x 4GB) DDR3-1600 Memory for my home built PC (which previously had 2 of the exact same make and model of ram). I slotted them into the 2 remaining slots and tried power my PC on, which it did for maybe a quarter of a second. After trying various thing to fix this (removing mobo battery, trying the ram in different configurations) the only thing that allowed my computer to power on and stay on was removing the GPU from the pci-e slot.

My mobo has no ports for a monitor to plug into to I can't access the BIOS I don't think, and I don't know anyone close to me that has any computer parts I could borrow unfortunately.

Complete list of what happens in which situation:

Everything as it should be normally: computer starts for less than a second then shuts down again, wont start at all until unplugged and replugged. No beeps of any kind.

Everything as it should be minus RAM/with RAM in different configurations: Same as above.

Everything as it should be minus GPU plugged into pci-e: Computer powers on and stays powered on, nothing on monitor, no beeps of any kind.

Parts:

AMD FX-8350 4.0GHz 8-Core Processor

Asus M5A97 EVO R2.0 ATX AM3+ Motherboard

Kingston HyperX 8GB (2 x 4GB) DDR3-1600 Memory (2 of these, so 16gb in total)

MSI GeForce GTX 760 2GB TWIN FROZR Video Card

Corsair CX 430W 80+ Bronze Certified Semi-Modular ATX Power Supply

Any help at all with this would be amazing, thank you!

  1. The GTX 760 requires a 500w PSU. Adding the additional memory has likely pushed your power consumption past the point where it can adequately power your complete system.

    To be clear, will the system boot properly with only one stick of memory installed?

    Just tried, same result as with 4 sticks inserted. As long as the video card is connected it wont start for more than half a second unfortunately. I think I might just have to buy a new PSU
  3. It certainly could be a failing PSU. That would be my guess at this point.

    Keep us posted.

    I will. Do you think a 500w psu should be enough or should I opt for 600?
  5. I would opt for a 600w minimum. I would recommend giving yourself some headroom and get a 650w, or so.

    What is your budget and where do you live (or shop on-line)?

    I live in London so I'll probably just buy it from Amazon UK, most local shops, even big chain stores overcharge for that kind of thing. Would this be alright? http://www.amazon.co.uk/Corsair-CP-9020098-UK-VS650-Power-Supply/dp/B00PGUSEBG
  7. That's slightly more than I can really pay right now, is there some kind of intermediate PSU that's somewhere in between these two in terms of quality and price? If not I'll have another look at how much cash I got for christmas and see I can afford the one you linked. Regardless, thanks so much for helping me this much!
  8. Go with your linked model. It is okay and should meet your needs. The other is just a higher quality unit. No worries.
  9. Ok I will, thanks a lot! Should I mark your post as the solution now and start a new thread if it doesn't work when it arrives or wait until it arrives and update this thread? Not totally sure how this site works, sorry.
  10. You can wait. No worries. Keep us posted on the results.
  11. Welp, I installed the new PSU a few minutes ago and still have the exact same problem... Is there anything I can try next that doesn't involve buying more parts?

    edit: worth noting, if the GPU is plugged in when I try to start the computer, it will only start for a split second once. Any other times the power button does nothing, even with the GPU removed. It only attempts to start again if you psu is turned off and on again
