I built my girlfriend a PC, I wanted it to be quick, easy to use and allow for minor gaming as well. There have been a few problems and I'm desperately looking for help to solve them. Specifications are at the bottom, please refer to this in order to propose a solution. The problems are as follows:

1. BSOD every time she plays a game. The stop codes are 0x1e, 0x0a, 0xd1, 0x50, 0x3b. The stop code varies from time to time but they are mainly the first three mentioned above. There have also been three instances of "unable to process a minidump file from the full dump file."

2. I replaced the Corsair H90 cooler because it was making a repetitive clicking/popping noise from the pump. Once replaced I used isopropyl alcohol to remove residue from the previous TIM and reapplied AS5. Temps in the BIOS should be around 25 - 35 idle but when I watched it kept rising. It made it to almost 65°C and then I heard a rush of liquid from the pump and the temps dropped quickly back down to 45°C where they remained for a while. It climbed back up to 65°C and the process repeated. It was my understanding that these coolers were supposed to operate a steady flow of liquid to maintain a certain temperature, it seems like the pump is only kicking in after it reaches a certain temp or something! Anyway, it's weird and I don't like it at all.

3. Realtemp doesn't support this processor, CoreTemp only displays CPU_TIN temps and not the individual cores which is the same for OCCT and HWMonitor. Why can't I see the temps of each core?

4. When I stressed it with OCCT it was telling me it was reaching a steady 50°C, even after 15 minutes of pounding it the temps wouldn't go above or below. I thought "great!" but then I realised it's only CPU_TIN temps and not the cores themselves. Could the cores be getting to a super high temp causing BSODs because the H90 doesn't work properly and I just can't see the temps?

5. PC is making this weird buzzing noise, I have no idea where it's coming from. My PC does it too and the only components we have in common is the cooler. When a friend of mine heard it from my PC he suggested it may be caused by HDDs spinning very slightly out of sync but it can't be this as my girlfriend's PC does it and it has only one HDD. Could it also be the cooler? When I push anywhere on the case it stops. Sometimes if I reposition the case it will stop entirely.

Specifications:

Motherboard: ASRock FM2A88M Extreme4+
CPU: AMD A10-7850k@stock
RAM: 8GB (2x 4GB) Patriot Viper 3@2400MHz (PV38G240C0K)
SSD: 120GB Kingston HyperX 3K
HDD: 1TB Seagate Hybrid SSHD
PSU: Corsair CX500M
Case: Bitfenix Prodigy M
Monitor: DELL 2209WA
OS: Windows 7 Professional x64 SP1 (Fully updated)

Further info:

▪ BIOS is fully updated

▪ I have tried clearing CMOS which didn't make a difference, BSODs still happened.

▪ I have tested the RAM for 10 hours on Memtest86 @ 2400MHz with no errors.

▪ I have reinstalled the GPU drivers and have also tried beta drivers.

▪ The H90 comes with two connections, one 3-pin for the pump and one 4-pin from the fan. On the motherboard there is a 3-pin CPU_FAN header and right next to it is a 4-pin CPU_FAN header. This is where the pump and fan are plugged into. I assume this is the right configuration. I have tried plugging the 3-pin pump into PWR_FAN but that just made it run full speed and I was worrying it would explode! I have also tried plugging it into a 4-pin CHASSIS_FAN header but the same effect occurs.

▪ I have tried plugging the RAM in difference configurations of dual channel (i.e. A1+B1 and A2+B2) but the BSOD still happens. Again, the memtest results were fine.

▪The BIOS configuration is completely default and still BSOD.

▪ The SSD and HDD are both plugged into SATA3 ports on the native controller, not third party.

▪ Windows is activated and I'm running Symantec Endpoint Protection SBE

Thank you so much in advance if you've taken the time to read my problems and help me solve them! This whole project has been an absolute nightmare for me and I'm on the verge of throwing this system out my window! If you require further information please reply and I'll get back to you ASAP!
 
If what you say is true about the cooler for the cpu.
Yes it should produce a steady flow rate.
But if your saying the heat builds up and you can hear a swoosh noise, it practically means even if it is a closed loop water cooling device it has air in it still.

An air lock.

Another note the bios of the board sets the rotation speed of a fan and a pump when dealing with rpm.

You should not have the setting for the Cha in the bios set to auto for where the pump is fitted.
The speed should be manually set in the bios.
Or the flow rate will fluctuate causing the heating.
As the rpm rate is governed by the thermal sensors of the CPU. if connected to the cpu set that to manual not auto in the bios to keep a constant flow rate.

Pwm enabled on the Cpu or Cha for a fan must be set manually not on auto, because the flow rate on a water cooler pump must be a constant rpm.
Auto Pwm lowers it set in the bios lowers it.

Water is more denser than air so if the voltage given to the pump via Pwm auto is not enough it cannot turn.
It requires more effort and current to turn a pump due to the density of water. By auto pwm the pump does not have enough current to turn, and produce the proper flow rate at a constant speed. = heat up.

AS a cpu heats up it ramps the pwm current up to spin a fan faster, but you have a pump that requires a steady rpm for flow rate. A set voltage.



It`s not what you do with a water pump connected to Cpu or Cha connection to a board.

It may of stated that when fitted the pump/cooler it must be set in the bios as a manual setting.
Not auto pwm monitoring of the board.
Most likely it did.


Have we got why it errors yet ?

All Corsair H90s have air in them somewhere I think, even if it's just a little bit because on the 3 that I've seen I can hear this liquid swooshing through the pipes. Unless the 3 that I've been through were all faulty haha!

Anyway, the problem is that in the BIOS of this board the option for both the 3-pin and 4-pin CPU_FAN header must be configured collectively, they are no seperate when configuring. So, I was thinking to keep the pump in the 3-pin CPU_FAN and configure it to manual with a high RPM to allow constant high flow. Then plugging the radiatior fan into a CHA_FAN header and configuring it seperately. Is this what you mean? Would this work?

 
You don`t its a closed loop system. you return it.

Anyway as said your problem is you have Auto pwm in the bios enabled.
For the cpu and cha fans of the board.

All you have to do is set it to Medium or high as a manual setting in the bios for what ever the pump is connected to on the board.

The pop sound was the motor getting enough voltage to turn at the right voltage provided when the cpu heat increased because that is what pwm does with fans.
The pump requires a fixed voltage set up in the bios, rpm speed.

Pump=voltage=rpm speed= flow rate of water in loop.
Slower= Heat buildup. Pwm low volatge set on auto pump does not spin at right flow speed. Or does not turn till auto pwm increases voltage. to spin fan or pump faster.




But you want a constant flow rate because it is a pump.
Water is more efficient at absorbing heat. so any lag in flow rate will cause a heating problem.
That is why you don`t use the auto pwm setting in the bios, but manually set the rpm speed to keep on top of the heat dissipation more flow rate, more heat extracted.
PWM auto in the bios settings of the board scuppers it.

I understand what you're saying. I've plugged the pump into the 3-pin CPU_FAN and the 4-pin fan into the CHA_FAN header in order to configure them seperately. That way I can configure the fan to run at low speeds to reduce noise aswell. Anyway, the only options I have for the CPU_FAN 1 & 2 speeds are these: "Full Speed, Performance Mode, Standard Mode, Silent Mode and Customize". When I customize I can set the percentage of speed I want it to achieve when a certain temperature is reached. Which one do I choose? If I try "Full Speed" my PC makes a huge noise from the pump shoving liquid through as fast as possible! Same with performance mode. Standard mode I can't hear it but the temps keep climbing in the BIOS.... I'm sorry but 45ºC - 50ºC is not normal for idling in the BIOS especially when I'm using fresh AS5!

Can you explain problem #5? The buzzing noise... Thank you for your time btw, it is hugely appreciated!
 
I know you said you replaced the pump.

Was there any kind of plastic layer on the contact plate of the pump block.
to protect against scratching was it removed ?
Daft as it sounds, you can often miss it, and often the fact of excess heating above what is expected, when the cpu is in idle mode.

Honestly that catches some people out.
Seriously have a check.
You may find it`s the case then Laugh.
How thick did you apply the thermal paste ?

There are two ways you must install the cpu cooling block depending on the cpu socket used.

If you use the spacers, and set them for the wrong type of socket you create a slight gap between the contact of the water cooling block and cpu die.
So it may be the cause.
