HELP? No signal on Monitor and running out of ideas[UPDATE]

post #1 of 7
Thread Starter 
I've recently had some trouble with my build after having moved it to a new case, and need some help figuring out where the problem is.

When I booted it up there was no signal to the monitor, and the fan of my graphics card suddenly sounded like a vacuum cleaner from how loud it was. I had ordered a new card (an overclocked Geforce 560) that I had been meaning to upgrade, and switched it out to see if that was the problem. Still nothing. I tried all the options on the OCN FAQ page. Pressing the ATX button for 30 seconds, cleaning both cards, etc. I switched the RAM around, tried getting an image without the HDDs, etc. But nothing worked.

I tried using another monitor, tried several different cables (DVI, Display port, etc.), switched the cards around on different PCI Express ports and nothing worked. When I boot it, the motherboard has the regular orange light and makes two beeps (I have two USB devices plugged in) and appears to be acting normal. None of the capacitors are broken either, but I don't know if it had somehow gotten damaged with static or what.

I'm hoping that it's just my PSU crapping up. I have an Ultra 750W PSU that I thought would be enough to power everything, but I'm not sure if it would be enough to power the 560 since it's OC'd . The case also has a few more fans and whatnot, but I'm not sure if that's worth mentioning.

My best guesses right now is: 1) the Radeon 5770 got damaged and the PSU couldn't power the 560, 2) the PSU is just derped up, or 3) my motherboard is going bad.

I have no idea what to do next. Any help? The mobo is an ASUS P6T X58, by the way. Thanks in advance!

Disconnect everything and try booting the motherboard outside of the case like on the cardboard box it came in. If it boots it's shorting it's self out if not check your ram.

Google "testing PSU with multimeter" to test if its your PSU.

750W is more than enough for the 560. Your guesses are as good as mine. Try borrowing a PSU from one if your friends and test with that, just connect the motherboard and GPU and RAM, no HDD's or fans or anything else.

First let me say, Welcome to OCN!

The wattage on that PSU should be plenty. Although I question Ultra's quality. Here is PSU calculator: http://www.overclock.net/t/1140534/psu-calc-final-release/0_60

It sounds like you've pretty much narrowed it down to the motherboard. Are you leaving off any extra power plugs to the motherboard? Maybe check that all the pins are getting into the motherboard from the power cable.

Your system is failing to POST. POST is a power on system test, when your PC turns on your core component go through so basic diagnostics and if everything is working, your motherboard will boot the bios. Their are 4 components that can cause a POST to fail, and they are, in order of descending likelihood

Memory
motherboard
graphics
CPU

If your computer turns on and doesn't die, your power supply is probably pumping juice into it. A bad power supply usually has other symptoms. If your case was causing a short on the motherboard, the computer would power on briefly and then die. This is not what you described. You have tried booting with different graphics cards already, so I think you can rule them out. The problem is likely either your memory or your motherboard. Check your motherboard manual, many motherboards have a "beep code" that corresponds to problems; there will be a series of audible beeps that are supposed to indicate what is wrong. LED lights on the board might also serve the same purpose. I would recommend booting from one stick of memory at a time to see if you have a bad DIMM. If that doesn't work, buy a 1gb stick or something from a local frys and test with that. You can always return it if you don't need it. If you can't fix it trying different memory, you will have to conclude it is the motherboard. It is possible the CPU could be the culprit. Unless you took the CPU out of the socket and bent some pins though, it is really unlikely.

Thanks for all the help, everyone!

I disconnected all the different components except for the CPU, GPU, and RAM, and tried booting with each individual stick of ram on each port with no success. The motherboard's LED was on, but it didn't emit any beeps at all. Tomorrow I'm going to see if I can get a new stick. If that doesn't work, it looks like it's time to get a new motherboard. :[

It seems like I'm getting a terrible bout of bad luck. I got a new motherboard and placed it in, and am still getting no signal. It is an EVGA x58 and I tried all the previous tests to see if it was the RAM or GPU causing the problem. I also got a new stick of RAM to test it with, still nothing. Fortunately, the mobo came with a set of diagnostic LEDs. When I boot it, it displays "FF", which means that it is trying to boot but cannot detect either the CPU, RAM, or GPU from what I understand.

Should I try switching out yet another m/b or look to get a new CPU? I have an i7 920 which are discontinued, so I'd have to upgrade.

EDIT: I think that perhaps my CPU is not the issue after all. On the new mobo I did not connect the 12V 8-pin power connector(The first time I had built it, the system ran without one, so I was a little adamant about plugging it in.). I will try this later today.
