Endless hardware issues

413x · 21 Jun 2020 at 21:58

I don't know where to begin. My desktop works but it has so many hardware issues part of me thinks I need completely new hardware!

Gigabyte z87x-oc mobo
Evga supernovae 1000w p2
1070 gpu
8gb of ballistix ram (dunno specs)
I7 4770k
H100i cooler

1. Take 1-10 times to post.
Never been able to solve this issue. Tried an old Psu and have different problems

2.pushing power button for a few seconds.. Pc turns off, then immediately turns on.. Only way to shut down properly is in Windows

3. Hard drives suddenly vanish from bios. Reboot fixes

4. Cpu cooler Seems to be acting up, once get into windows fans speed up to full, then calm down.

Have tried
Another Psu, but not sure if that Psu is any good
Removing gpu but can't seem to get on board gpu to work.

Most frustrating is once in Windows things seem 'ok'

Something is clearly off. I have a feeling the mobo is the issue. But how can it be fine after boot?

Also, I tried reseating a few bits and I struggled to even get the pc to turn on

Additional.

Its only from cold boot. A restart and everything is fine

It's very old

Issues have been going on for months, had a 12 month gap if being in storage too. Problems before and after storage.

Everything is old.

I'm gonna get a battery ordered
And trying components one by one.

I just can't get my head round how a pc can be fine in use but have so many boot issues!

Thanks guys.
I plan to tackle this properly at weekend.

Ill report back with solution.. Probably going to be a while

Update.

At the moment the suspect is looking like a ram stick.

Took 1 out, same problem.
Took other out.. No reboot.

As this is n intermittent problem it's not confirmed yet.

Didn't work.
Convinced this board is the issue. Probably going to just live with it. As it works fine otherwise

Further update.

Very strange

Got a new cmos battery :
no difference

Tried 1 stick of ram :
Seems more stable, but it's not a particular stick that causes the problem, it seems to be 2 sticks

Bios switch :
My bios was switched to 'backup' so I flicked the switch to primary and seem to be getting no issues at present.
No idea how long it was on backup. Might even have just knocked it

I believe it was/is something to do with ram.
When the boot failed the last few times the ram leds didn't come on, and the board diagnostic code seemed to stall on ram error codes.

At the moment I'm still on the idea of 'deal with it'.
I have rebooted 10 times now and no issues. But will need to leave it off overnight. As it can go a day or 2 with no issues before trouble shooting

Things I have done
New cmos battery
Every ram combination (different slots, single and dual attempts)
Bios switched from backup to primary.

That's a nice bit of trouble shooting there. Is it still working as it should?

Yes!

So strange.
Not had a single miss boot yet.

Its also fixed a separate issue it seems to do with what I and the forum thought was an OS issue!

Bravo, well done for the fix. Frustrating isn't it! Beeping computers!

I'm even impressed with myself.
Was hours away from an expensive and time consuming part swap out.

Not missed a beat since. Its literally 100 percent fixed.

How is it even possible for a bios to be that dodgy but computer still boots?!

Glad you have it running properly now, but.

Isn't using the power button forcing a shut down?

Thought the only way to safely shut down Windows was from the start menu.

Yes. That was a forced shutdown.

Sorry, read that as your usual way of switching your PC off.

Best to do it during an update I hear!
