DIY PC can't boot up properly

[Zerouf]

Hi I need some help!

I've recently just re-build a new computer. And am having an issue with getting it to turn on. Whenever I turn on the plug the motherboard's LED panel lights up showing that there's power, but when I press the power on button on the chassis it doesn't boot up. However after waiting 3-5mins of leaving the power on, and pressing the power button again the computer manages to boot up.

I've checked if the RAM or GPU is loose, I've plugged out 1 RAM and switching the places etc. I've even had to re-apply thermal paste because I was worried that there might be a bent pin but couldn't find any issue there. I've never faced any issue likes this before and because this is a DIY PC I can't just call any company to get it checked out. I'm wondering if it could be an issue with the PSU? Like it not being able to supply enough power?

These are the specs some of which are brand new and the others are salvage from my previous DIY. Any of you tech genius out there able to help me access this issue?

Specs:

New Parts:
Chassis: Phanteks Evolv X
MotherBoard: ASUS ROG STRIX Z390 F GAMING
CPU: i7 9700k
RAM: G.skill Trident Z 16GB 3200Mhz

Old Parts:
Liquid Cooler: Corsair H60
PSU: RM750 Corsair
SSD: Samsung EVO 250GB
HDD: Seagate 2TB
GPU: GIGABYTE G1 GTX 1070

Also after it manages to boot up I'm sent straight to the BIOS and noticed that the timing and date on the computer isn't accurate.

How old is the PSU?

You need to set the date/time in BIOS. If it resets each time you boot - (1) there should be a reset CMOS pin somewhere, please check that it is not connected; or (2) replace the CMOS battery (unlikely to be battery problem for a new MB though).

Everytime you boot you got sent to bios? Seeing you got a new mb, just send the mb for diagnose.

Assuming that you have plug the cables correctly.

Yeah I tried going to the service center this afternoon because I was worried about the pin being bent. And their service was pretty bad. They said they could fix it for $138. But I didn't ask about getting it diagnose though. Okay but you do think that it could be a motherboard issue right?

I got this PSU from the corsair service center after the previous one died out. I got this one about 4 years ago if I can remember correctly. Also there was a period of at least 5 months where all the old parts weren't in use because I had to save up to get the new parts listed.

And as I mentioned after taking out the CPU to check the pins I noticed there was a very small piece of debris that was stuck on the pins at first I thought it was bent but after getting closer look I decided to blow on it to see if it was a piece of debris and it came off. So am not sure if that might have short circuited the pins because the computer was up and running for a good 7 days till I started having this problem.

I'm currently using the computer right now. And my brother is suspecting that the 14 pin power cable that is plugged into the motherboard might be faulty?

Did you check your battery ? Because this msg seem to be problem with battery. Also if you are using trail sockets for you pc, you will need to THROW IT AWAY and plug in directly to the wall socket, this is inportant.

Any idea where I could get a replacement CMOS battery though? Any recommendations?

I'll try the wall socket later on during the day. Because now that I got it started up, when I shut it down and turn it back on it works fine the only problem is when I leave it off for a long period like maybe an hour or more?

CMOS battery is CR2032. You can find it in NTUC or most shops which sell electronics.

It's possible to be a dying PSU problem due to age though 4 years should still be fine. (I assume you don't have a spare PSU lying around to test.)

Don't think it is a CPU or 24-pin cable problem.

I suggest you try in order -

(1) check that the CMOS pin on MB is not connected
(2) replace the CMOS battery (unlikely to be the problem but CMOS battery is cheap so should test this first)
(3) bring the MB to Asus service center (should be Ban Leong, please check box) to test. Your MB is new so is still covered by warranty unless you bought it overseas.
(4) replace PSU

I've just tried the wall socket and it still doesn't work. The weird thing is that when I brought the PC down to sim lim the technician over there was able to turn it on by jump starting it. I've tried jump starting it myself but doesn't seem to work for me.

Also the MB LED panel does light up so it means that there's power right? I could try my brother's PSU.

 

[SkyShroud]

shouldn't your mb under warranty, why would they charge you?

 

[chaoprokia]

PSU problem 80%
MB problem 20%.

Change PSU to test.

u dont need to on ur PSU. when ur switch is on there is wire connection. MB lights will be on too.

it doesn't mean PSU its ok.

Ikr that's so weird Ban Leong was telling us that's how they do things. And if we want we can try calling ASUS directly to see what they can offer. But that was because we thought the pins were bend initially.

Ahh I see okay so that makes sense I did ended up trying my bro's PSU. And still had the same issue.

*UPDATE*

Called the technician again from Sim Lim he suggested removing all the pins connected to the MB besides the power for CPU and the 24pins and the chassis power pin. Computer booted up straight away. Although I heard a weird popping sound like as though something short circuited. ( I did check if there was any indication of burnt/damage, non I could find. )

So ended up booting the computer up each time while I plug in the rest of the chassis cable and so far computer seems to be working find. Went to work and got back home turned it on expecting for the problem to happen again so then I can identify which cable is faulty but ended up the computer booted up straight away.

Only thing I realize is that the date and time was left to when I turned it off? Like it's a watch that only works while the computer is on? So it might go down to the CMOS battery or some BIOS that I need to update?

Given your level of knowledge for DIY, i would suggest not to try out anymore troubleshooting by youself. Bring down whole PC to PC Care & Solutions, SLS #02-32 and look for Nigel. Explain your issues to him and he will help take a look.

Do google for the company name and his handphone number should show up. Do give him a call/sms/whatsapp to see if he is around on the day you plan to head down.

Actually you should not have asked them if they can help repair. You should just describe your issue then let them go test it out.

 

[chaoprokia]

if u heard a weird pop i suggest u bring to a technician to see. u dont know what went wrong. if other parts are shorted it will cause more damage to the pc. which you need to replace. as shadow84 suggested its time to bring to someone to check.

Cool thank you so much for the info and recommendation. Will definitely give him a call.

So an update on this issue. It's been a month. And I did consulted Nigel from PC care and solutions. He was kind enough to loan me a PSU to test out. And still had the same issue. Called him to let him know and he came down to my house to check it out.

This time he brought a spare MSI motherboard to test out and it worked fine with all the parts I had, he was also kind enough to loan it to me while I get this situation resolve. Emailed ASUS about it and called Ban Leong. Brought the motherboard down there and they tested it by jump starting and it worked.

So they had to send it to ASUS for further diagnostics. 1 month later ASUS has just sent back the exact same defective board to Ban Leong saying there wasn't an issue. And I'm at a lost right now. I called back ASUS and just got off the phone.

Was asking them to give me a replacement because it definitely is the motherboard and I don't want to go through all the hassle of having to get the MB from Ban Leong then going back home to assemble it and having face the same issue, bring it back to Ban Leong, and having to wait another month or so.

Ended up the call centre told me to email my case to them and they will sent it to another department that specialise in these issues/cases to see what they can do? I really have my doubts but as of now was told to give them time to get back to me and see what they say from there.

What would you guys do if you were in my position? Should I report it to CASE and get legal advice on the lemon law?
