Is my computer dead?

[Jack02]

So, this happened in November, I just haven't had the time/money to fix it. When I wasn't home, my little 8 year old sister snuck on my computer. I came home and it wouldn't turn on. I though my power supply had died. It was a crappy Thermaltake one, so yeah. I asked her and she said she didn't do anything. I just got money now, and was gonna buy a new PSU and some other stuff. I just wanted to make sure the rest of my parts were okay. She said now she put headphones by the CPU fan to stop it. She said she wanted to "see what it would do". Yeah so I think she killed everything. How can I check?

When you hit the power button, what happens? Nothing? Ok, possibly PSU.

 

Jump the PSU by shorting the power switch pins on your MOBO with something metal. Nothing still?

 

 

If neither of these work, it's probably your PSU or a cable is loose.

If you DO get fans and stuff to turn on, but it doesn't POST, reset the CMOS by unplugging it, taking out the button cell batteries on the MOBO, hold the power button, replace batteries and power cord, then try turning it on.

But she just tampered with the CPU. I think she fried it. My PSU isn't turning on at all. I took it out of the system and still won't.

If she stopped the cpu fan while it was powered and spinning, she might have damaged the motor, if the bios sees the cpu fan speed below a certain threshold, it may refuse to boot at all, if you've got a mobo speaker connected, it'll give the "cpu fan error" beep on an asus board.

I have a MSI Z97 Gaming 5 with a i7 4790k.

It's REALLY hard to damage a CPU by stopping the fan. It will automatically turn off if it gets too hot.

 

What happens when you hit the power button?

You need the truth from her or parts to swap in to diagnose. Theres no way sticking headphones near a fan would kill a system. As usual remove as many parts as possible for a minimal boot.

when you say it wont turn, does it physically do nothing when you hit the power? if so disconnect the power switch header and short the 2 pins to rule out the switch.

 

if you are getting lights and fans but no post, try a CMOS reset and reboot

Sometimes lights come on for second but then goes off. Usually nothing.

Like I said above, lights come on for a second sometimes then it immediately goes off.

do you see any codes on the boards code LCD ?

1) check if all the necessary switch is switched on

2) unplug everything, remove the cell battery on your motherboard, wait 5 minute and put the cell battery back in

3) re-seat the cpu and one stick of ram, as well as cpu heatsink (i suggest using the intel stock heatsink for fast swap, no thermal paste is needed for diagnosing)

4) connect the 24 pin, 8 pin cpu, gpu, and gpu power, and monitor to the gpu

5) jump the power button pins on your motherboard

 

does your computer post?

 

no?

6) remove the gpu, and the pcie power from it

7) plug your monitor into the motherboard

8) try powering it up again

 

does your computer post?

 

no?

9) list down all the spare parts you have and swap them one by one, see which one is dead

[Jack02]

Okay, so I have some news. I jumped both my power supply and motherboard. The PSU would only work for a split second if I wiggled the paperclip I put in the 24pin. My motherboard (MSI Z97 Gaming 5) would just flash this blue light and then the fans and LEDs on the board would flicker for a second. I took it out of the case and put it on the motherboard box. The motherboard was doing the same thing. The third time around it started to boot up, the fans started moving (including CPU fan) then it stopped about 5 seconds later. I kept retrying and it just would repeat itself. Now I have no metal touching the pins and it just goes on for a second every now and again (out of the case). What else should I do?

Sounds like your PSU died. Get a new one. What model is your current one, by the way?

A crappy Thermaltake TR2 500 from like 2013. It booted up for about two minutes a second ago then went off. I think somehow my power switch broke too. I should be going to Microcenter Monday :). any other suggestions?

Pretty much anything that's not a Corsair CX... EVGA and other Corsair ones are good.

Your power supply should provide power to the system as long as you jump the green wire to the black wire

 

Maybe a bad psu

if you're lazy to remember specific model, just grab anything from seasonic

 

if you want good specific models:

EVGA SuperNOVA G2

EVGA SuperNOVA P2

Corsair RM

Corsair HX

Corsair AX

are my general recommendations

 

or you can get anything in tier 1 or tier 2 from this list

 

your rig should be fine with a 550W, get a 650W if you want more headroom for gpu upgrades in the future

[stealth80]

or pretty much any seasonic or Enermax gold/platinum
