Based on there website, check to see if it shows in the bios, it may need an update. https://www.seagate.com/support/kb/internal-hard-drive-troubleshooter-006183en/#When%20the%20storage%20drive%20is%20no%20longer%20detected

Using a boot time scan or rkill may help in the removal. This may be an option to try before reinstalling window, boot time scanners are better at killing entrenched malware.

I would try to use hirens boot cd/usb on the computer to see if it comes up under disk management, format if possible in hirens (disk management) then use the installation usb. Can you also provide what hard drive you are using and computer spec? Hirens https://www.hirensbootcd.org/

Did you manually install the driver for that graphics card before replacing the new one? I would manually install the driver before installing the new graphics card. This also goes for upgrading other components. I releard this the hard way by installing a wifi 6 card on a laptop and forgot to install the driver first and lost connectivity.

I would not use windows 7, it is at end of life and will no longer receive updates or patches, like windows XP. With that in mind, it may be good for a temporary system while you wait for a little to get a new computer. In general, i would either upgrade the system to an SSD ( at least 500gb for heavy use/games, 256 for browsing the internet and light office work) and 8gb of ram for windows ten or wait for you new system if it will be within a short time frame due to the risks involved in windows seven at this point. You could also use Linux as a backup for the backup or for protected information such as taxes etc... If this is a work computer or something that holds valuable information such as PII (personally identifiable information, I.E., full name, address, social security number etc..) store and access this information on a different computer or OS with some form of encryption (lvm etc..). Do not use windows 7 to handle information that you would not be ok with posting online, this includes buying things online or saving passwords.

I would replace the HDD with a new drive ( for best results SSD) then i would upgrade the ram to 8gb at a minimum and install windows 10. windows 7 no longer really supported or patched by microsoft, in short windows 7 is almost like windows XP (https://support.microsoft.com/en-us/help/13853/windows-lifecycle-fact-sheet) . I would say based on what you are telling me, use linux till you get the new computer. I would then invest in maybe upgrade for whatever new laptop you may be getting if you don't want to keep you old system alive, that choice is up to you. You can alway just use linux on the old computer :-). sidebar: If you system is a duel boot, meaning windows and a linux distro installed on the same drive and was not manually partitioned and used a tool like easybcd to get it to boot, it can cause issues.

This laptop based on the information i can find is relatively old in the tech world. If you have not replaced the drive ( got the computer more or less then 5 years ago) or upgradegrad the ram to at least 8gb of ram the computer is not optimal in my opinion. To get to the nitty gritty, if you are running windows 10 on a laptop that was made for windows 7 and have not upgraded or replaced certain things this can cuases issues. Also if you have not upgraded the bios that can cause issues also; however dell sometimes makes this rather easy with tools or software. I have upgraded older computers in the past for people and they had same issue just with a super old desktop. I would replace the drive and try to upgrade the ram a little and try to shoot for 8gb, which i think is the max for your computer. Depending on distro, linux has a easy time running on older systems. the bottom line you may have multiple issues, old drive, old bios, and a computer that might not be able to handle the latest operating system of windows 10. You have 4 GB of ram but you did not say what type DDR4, DDR3 and so on. I would look into upgrades for a SSD/RAM and look at the the link below. The replacement parts in the link can be relatively inexpensive if you are looking for something that just works for daily tasks. there are tons of other things you can test like the memory with memtest (https://www.memtest86.com/). just one of the website i found. https://www.gizbot.com/computer/dell-inspiron-n4050-feature-filled-laptop.html Crucial upgrades for computer Inspiron 14R (N4050) (i think this is your computer) https://www.crucial.com/compatible-upgrade-for/dell/inspiron-14r-(n4050) P.S. benchmark your hardware (GPU, CPU, hard drive) with linux applications,there is a ton to choose from and all free. This can also help decide what you need to buy if somthing is failing or just windows not working on you computer.

please give me you computer spec.

Yes it is possible to copy files over if you have hard drive issues, however it is not considered safe (messed up os) or possibly incomplete/corrupt data. A zero fill is an option in linux using a disk utility or partition tool and it overwrites the data with all zeros. This can improve performance of a messed up ssd, along with a 4k aliment (Is a common standard off the shelf like a evo ssd). A format does not delete the data, just address table, so a OS can't see it without using software like recuva. A secure erase makes so the old data is completely unrecoverable. If your hard drive is a HDD, you re-installed window and still had issues (benchmark tool crystal disk as a measuring tool) i would say the drive is dead. The military has a 3 to 4 year rule for tech refreshing all their laptops etc... based on hdd failure after prolonged use and so on. steps i would take: 1. backup all data from the drive using one of the option below based on your need, one usb drive to boot off of and another drive or cloud service to store recovered data. copy files with a portable version on windows (on usb) or linux (https://www.hirensbootcd.org/ is a good choice for windows) mirror the drive,partition or create a iso (gparted, acronis etc...) optional task that may help before recovering data and may also fix the issue for a short time, use the command prompt as administrator and run (on windows boot usb) "chkdsk (letter of drive here): /r" without quotes or parentheses. 2. secure erase the drive so data from the old drive cannot be recovered and fix potential issues (ssd, and won't hurt on a HDD) 3. reinstall windows and benchmark the drive with crystal disk (https://osdn.net/projects/crystaldiskmark/) you can gauge the drive performance by looking at the expected speed online form the manufacturer using the S/N or other information. p.s. you can use the ISO or other forms of a drive image to place your old OS and files on a new drive.

This could mean two things, hard drive issues ( old and so on) or a issue with windows. I would bet on the hard drive having issues. Check the connections the hard drive and the system for the hell of it also. If it can run on linux but not on windows check if it is fat32/ntfs or ext also. It may also be a corrupt partition that linux can read but windows can't. I have had messed up usb drives etc.. that can be read somewhat on linux but not windows with partition issues. The fix was a zero fill erase and reformat (with linux system ) as fat32. Hard disk failure is the most common regarding this issue on the other hand. Gparted bootable usb may provide a few options to fix the drive, erase or other functions that are described in the link below. Link: https://gparted.org/livecd.php

Do you have a video or something you can post on here, more information the better. Any recent such as upgrades over clocking etc...........?

It sounds like a driver issue, try disabling and reenabling from the device manager. If that does not work, try to uninstall the driver with the device manager with the device unplugged, then plug in the device. If all attempts above do not work, uninstall the driver with the device unplugged and then try to install the driver from the manufacturer page. link for driver: https://www.tp-link.com/us/support/download/archer-t3u/

please provide spec and any error code on the motherboard etc...

If your a using thunderbolt or not there are two possible issues,when you connect your oculus you should be prompted to allow the device on the oculus itself and some computers (like mine) have thunderbolt security measures that if a device is not allowed or if it has been denied it wont connect. My computer has a setting in the bios and software called thunderbolt control center to allow or block devices. My default is to not allow anything till the user has approved the external device. Maybe give this a try to see if this is causing the issues. Employees at work used the oculus and had issues and did not know to put the headset on after plugging it into the computer and allow the computer to connect to get it to work.

you could try kingston sdd software to troubleshoot. https://www.kingston.com/us/support/technical/ssdmanager
