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 contents of the squares itself changes. This says to me that VRAM is being corrupted. Occasionally there are other artifacts, like polygon spikes, in games. This is affected by physically pushing on t...

My site http://iosre.com is built upon discourse. It remains unreachable after setting up fail2ban. I've asked the question on their official forum, but their staff said it may be a general server problem and suggested superuser. I guess my website may be under attack, but since I'm not a server expert, I have no idea what to do the fix or track down the problem. Any ideas? Thanks! Let's block ads! بخوانید...

First - yes I support old stuff... not blades and the like, Racks of 2 and 4U servers, up to 16 of them in a set. A hardware IP KVM solution in new deployments answers all of my issues, my gap currently is that I want to equip each location I support with a low cost Dongle they can coect to any troubled server (say they blow up the BIOS settings and need help or the RAID controller needs configured or maybe a server is blue screening and we need to capture the stop data after windows crashes remotely). Hardware standalone IP-KVM dongles exist and work adequately yet always need an IP configured. I am seeking a device that I could plug into any nearby working server via USB, and it coect to t...

I was setting up an LG LG 27MB85R-B 27" monitor at a desk and after I plugged in all of the cables and plugged the Mini-DP into my macbook. I tapped the touch sensitive power button and... nothing. I rechecked all of my cables to make sure I didn't miss anything but everything was right. At this point I don't know what's wrong! Help! Let's block ads! بخوانید...

I am using Samsung SSD 850 EVO 500 GB. Instead of installing a fresh copy of Windows 10 on it, an old image of the OS created from an old HHD was used I am worried this may affect the performance/age of the SSD. Which I understood is made to run on 4k bytes per sector. screenshots are on my laptop now after the migration to the ssd. Let's block ads! بخوانید...

yesterday, I updated my Windows 10 x64 Build 1607 installation, and after the updates were finished, I decided to manually reboot. That took me to a black screen with a set of white circles rotating at the lower end of the screen. This process didn't stop, so after 10 minutes or so I began googling on another computer, finding a possible solution: unplug any USB receivers, and when I tried this with the USB receiver of my Logitech M510 mouse, Windows booted immediately to my desktop. Unbelievable, but I would like to understand why this happens at all, especially regarding the fact that users reported similar behaviours back in 2015 already, so one would assume that Microsoft must have fixed...

After upgrading to windows 10 I have this aoying problem. When I use two finger scrolling, the icon that appears during the scrolling gets stuck on screen. After 30-60 minutes of browsing I will have a few of those and the only way to get rid of them is to log out of windows. I have an old Dell XPS 15 and it has a Synaptics PS/2 Port Touchpad with driver version 19.0.15.2 Let's block ads! بخوانید...

I will go in vacation in a couple of days to the beach. I plan to leave my computer (a mid 2012 Mac) in the car, which will possibly be exposed to the sun. It will be exposed between 14:00 and 20:00 and during this time temperatures can get as high as 38 degrees Celsius (100 Fahrenheit). Will this be a problem? Will I risk to ruin the battey / computer? Which precautions can I take? For example, is it better to leave in the trunk or in the back seats? Should i tu it off? (usually I just close the lid) Thank you in advance!

I am considering buying a Nvidia GTX 960 to put in a Proliant DL320 G6. The Proliant has: Dual Redundant 400W power supplies 2x Full sized PCIe 2.0 x16 slots From What I have read Nivida says 120W Graphics Card Power 400W Recommended System Power With current Hardware ILO shows I don't go over 200W... Thus I should Have 80W to spare, Right? I also know this would fill one PCIe Slot, but fill both PCIe Spaces. I am also aware that this card is meant for PCIe 3.0, Thus even with PCIe backwards compatibility I wouldn't get the full bandwidth. It looks good to me... But to anyone with experience, Let's block ads! بخوانید...

I frequently use Search function inside Zend Studio software (which is built on top of Eclipse). I use it a lot. Probably 10-100 times a day. I have experienced a mysterious variety in search time, when I use Search to find a string in one of the files inside the Project. Often it takes just a second to complete the search request. But sometimes it takes 10-20 seconds, and that is the issue I seek to resolve/diagnose. What I do: press Ctrl-H (opens up the search menu) type my search string press Search usually it takes about 1 second or less, but sometimes it takes 10-20 seconds [and that is the issue] What I See It happens sporadically, not all the time, but it happens frequently nonethele...

I plan to use robocopy to move files and folders from a directory on a server to a directory on a hard drive, using the following command, robocopy [source] [destination] /e /move /xo In the event of a file name conflict, I understand this to replace the files on the hard drive only if it is newer (or exactly the same age?), and then to delete the files that have been copied. Ideally I would like the source directory to be cleared of files, but I suspect there may be a problem; if a file is not transferred (perhaps it is currently in use, or a newer version exists in the destination) then it will not be deleted. In the case of an actual error in the copy process (e.g. if robocopy refuses to ...

I have 3 computers ruing windows 7 coected to a wireless router and each computers are assigned with dynamic ip in the range 192.168.0.30 - 192.168.0.253, subnet mask 255.255.255.0, gateway (router) 192.168.1.254.

My laptop fell on the ground and its screen cracked. Everything works perfectly except of course the broken screen. I ordered a new one already. My conce is that, because of these large dark areas, it may harm the powering system somehow... may cause some power leakage of some kind, or affect the screen cable or the screen socket. My question is that if I continue working with my laptop for a few days, will it harm my laptop in anyway? Let's block ads! بخوانید...

I'm trying to create a bootable Arch Linux USB installer from Mac OSX El Capitan. I followed the tutorial on the Arch Linux Wiki, but when it "completes," I get a waing that The disk you inserted was not readable by this computer instead of getting a bootable USB media.

I have simple alias for writing to log files: logtee() { ${TEST_LOG_FOLDER:?"empty_log_folder"} tee -a $TEST_LOG_FOLDER/$1 } I'm reading the folder from environment variable. However, when I try using this alias by executing echo 'this is reading path from env.variable!' | logtee whatever.log it works, but the output is: sh.exe": /d/my/log/path: is a directory.Did I do something wrong? Why does reading environment variable evaluate it? I suspect it have something to do with a fact that it's an alias, because in usual .sh script similar code works without any issuesP.S. I'm using msysgit on Windows 7, may be that's the problem? Let's block ads! بخوانید...

Recently I updated my PC from Windows 7 to Windows 10 and everytime I tu it on for 20-30 minutes is extremly slow. Task Manager shows disk at 100%. I checked why and I found out that is caused by ek.exe and other process but this one looks the main reason that slows my PC. I'll show you some of these processes (there are many more).

I recently built a new computer, using a Z170-a motherboard, Intel cpu and gtx 970 graphics card. I double and triple checked all the coections before power up. However, when I powered up the machine, it would not boot into bios. I tried several tips off the inteet, discoecting and re-coecting all components (and powering down each time). However I still get the same result - no boot up. The DDR4 ram chips I used were 2 x 8gb ram (total 16gb), plugged into the correct sockets. I just can't understand why I can't boot up the computer. I've built several PCs in the past and have had no problems. Any ideas? Let's block ads! بخوانید...
