PC crashed and now the peripherals don't work

[veerorith]

Basically I was playing bf4 and the pc crashed. It froze up and I turned it off then back on. When I turned it back on the peripherals won't work. The monitors don't turn from 'yellow' idle to 'green' receiving signal. My mouse has lights on it which don't light up at all. The keyboard doesn't light up the numlock, etc keys.

The fans are running. The HD is spinning. Everything internally seems to be working. Everything outside the pc just quit on me. The peripherals work connected to my laptop.

I tested each of my 3 sticks of ram individually in the pc. That didn't seem to work. Booting it ramless obv gives the beeping error code of no ram.

Hardware wise this is my pc:
(I built this myself around a year ago)

AMD FX-4300 3.8GHz Quad-Core Processor
ASRock 970 Extreme3 ATX AM3+ Motherboard
Corsair XMS3 8GB (2 x 4GB) DDR3-1600 Memory x2
Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Gigabyte Radeon HD 7870 2GB Video Card
Rosewill CHALLENGER ATX Mid Tower Case
SeaSonic 620W 80+ Bronze Certified Fully-Modular ATX Power Supply
Lite-On iHAS124-04 DVD/CD Writer


I've researched this a lot. It seems it may be the mobo but I really hope not. I'm not sure how to check that though. The other solution I saw offered was to unplug the pc, press and hold power button for like a minute, then let go and replug in pc. I tried this but Idk if it will work with my pc. My power button is kinda finicky as it takes like 2 presses to start the pc up as if it wasn't quite as sensitive as it should be, and that power button itself will not turn the pc off when held down. I have a seperate reset button so maybe that will work?

Anywho, thanks guys, this has been kinda killing me especially since I work part time online as well.

Hi, have you tried another GPU?

Because if monitor light is yellow, it doesn't receive signal from GPU. So first I would check GPU, then mainboard.

The reason I feel the video card isn't the issue is that its having the same effect on the keyboard and mouse. No signal or power of any kind. I'll try running the pc off of the mobo graphics tho just to be sure

As you said yourself, your computer beeps when you take out RAM, which means, that next component being initialized is your GPU? Next your keyboard would flash and so on. I think that is where you should start looking, also you can check your mainboard for swollen capacitors? When
i check for faulty components in a PC, I also start with taking out RAM, and see if it beeps, then try to swap GPU, and if that doesn't help I check the mainboard.
P.S. just wanted to confirm, you are not getting one beep? Did you get one beep before when computer finished initializing and started booting?

never had any beeps when the pc was functioning. It was the 3 beep, wait repeat 3 beeps. error code for no ram.

So I've taken out my video card and realized 2 things.

1. my mobo doesn't have build in video so I'm looking for another shitty one from friends I can test with.
2. my old card was always really big and seemed to sad in the computer. It looks like the pci e slot may be pulling away from the mobo so that may be the issue.

I'll update more when i get back from work and have more time

Yes, try to borrow a video card. Might be RAM issue , but I highly doubt it, that all 3 sticks would be faulty. Also you should fix your power button, to be safe in the future. And pci e slot pulling from mobo, well that's something new , probably because of a lack of a backplate, I am also using gigabyte card (same size) but mine is with a backplate. Such big cards tend to bend, and things happen because of that. Just be careful, and maybe take a closer look at your mainboard, especially at pcie slot. So post your progress and good luck.

So I got my brother's old video card and tried it in both the pcie slots. Seems like its the mobo if there isn't anything left to test :/ I'll talk to my dad and see if I can borrow an old mobo from him so I can test the other parts individually to be sure, but I guess I'll have to get a new one. Thats okay, I need to upgrade my pc soon, this just gives me an excuse to get a mobo that can take all the newer parts and then get the parts as I get the money.

If you have any other ideas let me know, otherwise I'll just wait till I can test the other parts and plan on a new mobo eventually.

Hey, at least it wasn't my nice gaming video card. That was a relief lol.

Yes test all the parts you can individually, and if everything is fine, look for a new mobo. I would recommend to find used mainboard (maybe someone you know has one, because buying a used one is a bit risky), until you save enough money for a nice new system
But before that check everything, and then decide on your upgrade path.
