windows 10 – PC crashes with debug LEDs saying “CPU not detected” when I try to run the game: Valorant. But it can run the game with integrated GPU

My graphics card is GTX 1650. My CPU is core i5 7400. My motherboard is MSI B250I gaming pro ac. I have the latest drivers for everything. Game used to run perfectly until last night. I had to move my pc from one room to another and suddenly this problem started happening. Everything works fine as expected, except for Valorant. I can do my coding, studying, etc. without any problem.

But when I start Valorant, within a couple seconds the monitor says no video input. It sounds like the turning off but some parts of the computer stay running. The CPU and GPU fans keep spinning. Hard disks keep spinning. RGB stuff keep working. But the debug LED indicates “CPU not detected” (according to manual from MSI website). But no buttons or inputs work. Even the restart button on the front of the casing doesn’t work. I have to turn the power off and on again to restart the pc.

Since it says no video output, I tried to see if the problem is with the GPU (although the debug LEDs say “CPU not detected”). I removed the graphics card and tried to run Valorant with the integrated graphics adapter (Intel HD 630). It ran fine without issue (not counting 30 fps max as an issue here). I played some deathmatches just to make sure the game was not the problem.

I later uninstalled the graphics driver using DDU and reinstalled the latest one again. But the problem persists. I uninstalled and reinstalled Valorant too. Didn’t help.

Does anyone have any idea or suggestion that I can try? I can’t even pinpoint the problem in order to begin troubleshooting. Runs fine without GPU when CPU is doing all the work. But crashes with GPU installed and says “CPU not detected” when most of the workload is alleviated off of the CPU. Please help, thanks!

windows 10 – How much does “integrated graphics” reduce system performance & stability?

I’m a programmer running Win 10 Pro 64-bit with 16gb RAM. My current laptop is my first without a dedicated graphics chip and also by far the least stable. I don’t play games and don’t need a high-end graphics chip for my usage, it was more when PCs had only 2gb or 4gb memory, I was always wary of “sharing” memory with the graphics processor.

My previous machine maxed out at 8gb and ran Windows 7 Pro. It occasionally froze up or had memory issues but they were rare. Now I run Win 10 with 16gb and I get Out of Memory errors and weird behavior all the time. Driving me nuts!

To be fair, I usually have 2 IDEs open (client app & server backend), a Slack/Discord client, 100-200 Chrome tabs, and various utilities. Without a doubt, web pages are much more bloated in 2020 than in 2017 or so, so keeping those tabs open definitely chews up more memory today. When there’s a memory issue, killing some memory-intensive tabs in Chrome’s Task Manager is usually enough to reclaim enough memory to compile my program again, but only for a while. Memory usage is always high, as I write this Task Manager stated memory consumption is 81% even though my user profile is only 6.2gb.

With all of that said… I can’t help but think that a dedicated graphics card with its own memory, which left the CPU and system memory alone, would increase system stability and reduce the memory issues I’m having. This is a laptop so I have no way of retro-fitting a graphics card, my decision is really for determining whether to make a dedicated graphics chip mandatory when I buy my next laptop. Any insight is appreciated. Thanks.

macbook pro – Is it possible to use the integrated gpu on MBP retina with Bootcamp?

No, sorry. Apple disabled switching between the (integrated) IGPU and GPU.

I haven’t tested what you posted, and I doubt it will work. (Still 1.3 years left on my warranty)

windows – How do you stop a single domain controller from participating in Active Directory Integrated Zones and instead use file-backed zones?

I have three domain controllers. DC1, DC2, and DC3. All are functioning as DNS servers for the internal.company.com domain.

There are two zones, internal.company.com and the reverse lookup zone 168.192.x.x-in-addr.arpa.

Both of these zones are Active Directory Integrated Zones.

I would like to make DC1 stop using AD integrated zones and instead use a file-backed secondary or primary zone, performing zone transfer from the other DCs to get the zone info. DC2 and DC3 will continue to replicate DNS zone information between themselves.

In a lab environment I have tried to:

  1. Log on to DC1 and open DNS manager.
  2. Right click the internal.company.com zone and selected properties.
  3. Select change zone type.
  4. Uncheck store in AD.
  5. Check secondary zone.
  6. Applied and hit OK.

The zone then disappeared from my other DC in the same site. I naively thought that my change would only apply to DC1. (I.e. that the only effect of my change would be that DC1 would just have a file-backed secondary zone).

In my lab, DC1 is 2003 and my DC2 and DC3 are 2016 RS1.

Is there a recommended way to make DC1 use a file-backed zone instead of AD integrated zones?

stochastic processes – How to understand m-fold integrated Wiener process?

Consider a stochastic process

$$X(t) = sum_{j=1}^m theta_j frac{t^{j-1}}{(j-1)!} + sqrt{b} Z(t)$$

where

$$Z(t) = int_0^t frac{(t-u)^{m-1}}{(m-1)!},dW(u)$$

where $W(t)$ is a Wiener process. Here, $Z(t)$ is called a $m$-fold integrated Wiener process.

My question is that how to understand the process defined here? For example, what does it “look” like? What are some “commonly known” (e.g. $MR(p), AR(q)$) models that can be described in this form?


Some of my attempts: I have computed some special case. When $m=1$,
$$ X(t) = theta_1 + sqrt{b} Z(t) = theta_1 + sqrt{b} int_0^t 1,dW(u) = theta_1 + sqrt{b} W(t)$$

This is easy to understand: a constant level plus a scaled Wiener process.

When $m=2$,
begin{align*}
X(t) &= theta_1 + theta_2 t + sqrt{b} int_0^t (t-u) ,dW(u) \
&= theta_1 + theta_2 t + sqrt{b} left{ t W(t) – int_0^t u,dW(u)right}\
&= theta_1 + theta_2 t + sqrt{b} t W(t) – sqrt{b}mathcal{N}left(0, frac{t^3}{3}right)
end{align*}

This is not so obvious to me what it is.

Laptops integrated microphone ringing noise when camera is in-use

I am using an Asus (n552vx-fy024d) laptop from 2016. The laptop has an integrated webcam and microphone. The microphone works flawlessly when the camera is not activated. But, when the camera is in use (by any software), the microphone makes a ringing noise. Also, this noise changes tunes depending on the video resolution.
