Home-built computer help: No display after installing new case and water cooler aio.

[zrider99]

Hi, I recently upgraded my case and cooling unit and afterwards my computer turns on, the graphics card lights up, the fans are running, you can hear the hard drives spinning, there are no beep codes from a seperate speaker i got from amazon, and no display. I'm a generally tech savvy person but i am baffled by this. I looked through past threads to see if there was an answer to my problems but there wasn't really one. I did go through the standard checklist. I even re-seated the cpu and took the mobo out of the case and tried it in a setup environment. I don't really want to take it into a tech shop and be charged $150 for them to tell me my processor or motherboard is shot. So I'm here as a last resort.

My system -
MOBO - Asus M5A87
CPU - AMD- 8350
GPU - XFX R9-290
PSU - Corsair 750M
COOL - Corsair H110
CASE - NZXT S340

Are you sure it's not your monitor or the cables you're using?

Had the same problem and the problem was with the Power Cable, if you have a different one, try with it, I know it ain't much but worth a shot.

ok so if you have tried trying different ram different screen cables and everything your doing is right so that means 24pin mobo and 4 pin cpu then try a new cmos battery i woke up one day and my pc would not fully boot i was crying that bad spent so much time then i took out the cmos battery tried to boot and it did so i turned it off and went to the shop and got a cmos battery my and my motherboard have been happy since all hail gaben !!!!

 

[amd4lif3]

also try it outside of the case because maybe your standoffs have not been tightened if it works outside the case then tighten the standoffs

 

[amd4lif3]

oh just re-read soz yeah you tried it outside of the case well then cmos battery is your best bet

 

[zrider99]

Ok, I'll try the battery and report back.

 

[amd4lif3]

 

[zrider99]

Unfortunately, still no boot. Do i need to replace the battery or should it work without the battery?

 

[amd4lif3]

depends on the motherboard for me it worked without the battery but different brands may do it differently hmm

 

[amd4lif3]

try this take out the power cord and hold the power button for half a minute

 

[amd4lif3]

then plug the cable back in and try to boot it

 

[amd4lif3]

also try to see if you get a picture on intigrated graphics maybe your graphics cards failed on you

 

[amd4lif3]

if you have another psu try that

 

[zrider99]

Still no boot. :/. Unfortunately i don't have another psu, but it shouldn't be the psu because the gpu is powering on and so are all of the case fans. Also the power light on the mobo is on.

 

[amd4lif3]

YEAH but do try without gpu in once i had a graphics card which seemed to boot but never gave a display it was a dead card

 

[zrider99]

Sorry, was in class all day. The mobo doesnt have an output without a graphics card.

 

[amd4lif3]

sorry fell asleep was rewiring headphones yesterday and then fell asleep lol, k so try another graphics card any even if its from your mums pc or something lol or ask a good friend to try your graphics card in their pc

 

[zrider99]

Update: So I've tried a different one of every part except the motherboard. Graphics card is working, I'm not positive about the CPU but I tried another CPU and it still doesnt work. I'm about to buy a new MOBO and came here to see if there's anything else i should try.
