I have a machine that has been damaged by some careless couriers, and want to replace the damage parts efficiently. I have limited opportunities to test components in other computers, so I'm trying to find out what is broken in other ways. I have two main issues: Graphical artifacts. These take the form of small grid-aligned squares which usually appear and then flicker form position to position. If the display driver doesn't crash, they often settle down to a final position, and sometimes the ...

Recently started working as the tech support for a small company. Recently I leaed that they've all been experiencing graphical glitches with Microsoft Office that I think might be a symptom of larger issues. Has anyone ever seen a graphical error like this before and if so how was it resolved? Here's a video of the glitch: https://goo.gl/photos/E2oynsAXfNJMTaau9 It's affected both Office 2010 and 2013, other programs are affected at the same time, its not reproducible as far as I've been able t...

Is there a function that can be entered in column N which will highlight the empty rows by retuing a specified character? If there is a function would it also work in MS Excel?LibreOffice Let's block ads! بخوانید...

windows 10 x64 pro, Asus z170p, BIOS version old. AMD graphics card. As you all are facing, I am facing the beta graphics driver-secure boot problem after windows 10 anniversary update, seems like microsoft hates non-WHQL drivers and I can't properly install beta drivers in windows 10 anymore. So I need to disable secure boot. But I can not disable secure boot from BIOS, the option is grayed out in BIOS. I even tried Windows->Settings Menu-> Update->Advance Startup->Troubleshoot->...

Currently I was making some graphs and manipulating some data. It looks pretty good so far. Problem is : I left my work computer at work, and need to have some graphs tommorow. The work computers generally all have Excel 2007. I was having some problems earlier today making the graph on my work computer and got home and dabbled around and finally got my desired graph. Now I'm not sure whether or not this is because Excel 2016 optimizes some things better, or I just formatted my data much better....

I am creating a large tar archive and I would like to create the checksum of the archive too. I could achieve it like this: $ tar cfz archive.tar.gz files $ sha256sum archive.tar.gz > archive.tar.gz.sha256sum But the archive file is huge and on slow media, so I'd prefer not to have to read it all in again after writing it out. Can I build a pipeline that will hash the file as it writes it? I thought maybe I could do this with the tee utility, but that only writes to a file, not to the stan...

I have a Gigabyte GA-Z97X-UD7 with 2 Sapphire Tri-X R9 390 cards and an MSI R9 390X. The MSI and one Sapphire are plugged into PCIEx1-PCIEx16 risers because I'm using them for mining ethereum. On the Device Manager and when I run wmic path win32_VideoController get name windows only shows two R9 390s and the built in Intel HD 4600 graphics. Yet when I run the claymore mining program, I start mining on the 390 and the 390x but not the second 390! (as verified by both the logs which recognize the ...

I've been looking around online for an answer about the compatibility between Cardboard and PCB for the purpose of a Dust Cover. Found nothing, so I came here. The reason I'm thinking about this is because of two factors: one, that my Graphics Card's PCB is exposed and there is no backplate as some do these days, and two, my house is overly obscenely dusty. I end up dusting my computer every week or so as I fear the graphics card, above all else, would short circuit somewhere on the exposed micr...

Hope you can help me with this one, and help me to understand, I'm not really to AMD stuff. I just would like to ask multiple questions regarding with this matter. I have little understanding with this topic, for the many past years Intel was Known and used by majority of people - I believed. And every time they used Intel CPU's - iSeries it usually accompanied with Graphics card - NVIDIA (Whenever I used to view/canvas laptop in the market with the sticker NVIDIA graphics it in). Here's the sce...

I'm trying to teach my kids to save so I'm giving them the chance to deposit money into a "bank account" that pays interest (that I run). I'd like to create a spreadsheet to track the current value of their accounts. This seems like it would be easy but I'm having trouble figuring it out in excel. Given a worksheet of deposits and withdrawals on various dates - how do I calculate the current value of the accounts assuming a constant interest rate (interest rate never changes)? 1/1/2016 +$10 1/4/...

I have devised Audit workbooks with up to 21 pages with Yes/No tick boxes for each question. I have linked each tick box with the Yes/No cell for each question (very time consuming) but I need to now have a final score on the last page to add up all Yes (True) answers so i can then do another formula to calculate the percentage. I have not really got room to add another column on each page as space is limited. I was hoping there is a formula i can use at the end to cover from Page 1 to end? Many...

There's new default Calculator app in Windows 10. Is there a way to get rid of calc.exe file from system32 folder? Reason: I don't want any built-in apps, but I have a habit of running calc command via Win+R. I removed Calculator with Get-AppxPackage -allusers *windowscalc* | Remove-AppxPackage but every time I run calc it reinstalls back. When I try to delete/rename the file, it says that it's write-protected, although it's not running (at least it's not listed in the task manager). Alteativ...

At least I can try. :^) Let's block ads! بخوانید...

I have multiple sets of data that compare the capacity of vehicle's battery (Y) to the distance traveled (X). The data needs to be overlaid on one plot in order to show the different distances achieved by the vehicle, but I have no clue how to plot it all on the same graph as I have so many different unaligned/normalized values. For example: Distance (mi) [1] Charge (%) [1] Distance (mi) [2] Charge (%) [2] 0 99 0 99 0 ...
