louddifference :
ive just recently built my new gaming rig and its been working for about a week, but now when i try to boot or come out of sleep, it does produce a image or post and the cpu led is on. i have to keep trying to turn it on, sometimes taking 5+ times.
i have no idea what is wrong and i need help!
also when i built my comp at first i had a psu that didnt have support for the gpu i am getting, so i returned it and at the store they tested it and said it was defective, my new psu is a tx850 by corsair. so could it be that my new psu is bador my old one fryed something?
help! 🙁
So, to clarify, you meant to say that whenever you try to take it out of sleep or power it on, it does NOT produce an image until you attempt it 5+ times?
If so, am I correct in assuming that you are indeed able to get it running at some point?
If that's the case, it's probably not the CPU -- generally, a dead CPU won't boot at all. However, stranger things have happened -- for example, if the CPU was overheated to an extent that it crippled it.
However, most likely it's another component causing the trouble. My first thought is the motherboard, but let's examine the PSU first.
What brand and model was that original PSU? A faulty poor quality PSU can kill or damage components, so that is a pretty reasonable guess. It's possible your new PSU is faulty, too, but less likely. That's a pretty solid unit. Can you have it tested at the store?
Other than testing your PSU, I would first make sure all your power connections and interface connections are secure, everything is hooked up where it should be, RAM is seated properly, Motherboard is on standoffs, graphics card is seated and powered properly (if you have one. You said "GPU I am getting" so I'm not sure if you're using one right now or not), CPU cooler is installed correctly and making proper contact (and has thermal paste) -- the basic stuff that perhaps you've already checked.
If all that checks out fine and you're still having problems, I would swap out only the motherboard (maybe a shop can loan you one?) and see if that helps. If that's not the issue, try swapping RAM or using just one stick of RAM (or you can try the RAM before the motherboard since it's much easier to swap out). You might also consider trying a different CPU if you can borrow one, or trying your CPU in another machine if someone will allow it.
Let me know if none of those things solve the problem.
Also, do you have an internal speaker connected to the mobo? If so, does it produce any beep codes? I know you said the CPU LED was lit, but that can just as easily indicate a bad motherboard that can't communicate with the CPU. In that case, I'd also check for bent pins.
