I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I have bought a samsung evo 250gb ssd to install my os partition to it from my HDD. I have created a recovery usb drive from my present HDD(controlpanel->recovery->create usb recovery). Then removed the HDD from the slot & replaced it with SSD & boot the system. While booting up i have selected boot from my USB drive which have the recovery, & continue the steps & finally submit the reset button.System shows "Resetting the PC" & after 10 seconds it shows a screen saying 'There was a problem resetting the PC, no changes were made'. I have tried several times but the same message came. Can any one please help whether the steps followed by me are correct , else please help me. Because i'm facing very much slowness with my present HDD(WD 5400 rpm), that's what i'm planned to move the os partition to SSD & keep the HDD in place of optical drive bay using a caddy. I don't want to loose my Genuine Windows 10 with my present system. So please help me with a resolution.

Since you have to hunt around different Lenovo sites (and other sites) to find out about these softwares, I decided to make a post to get feedback from actual Yoga owners on how these programs interact, what they do, which ones are prerequisite, and which ones are unnecessary. Please don't take this as a blanket answer. This is just what I have found. It might be right - it might be wrong. I'm looking for others to post their experiences as well. Lenovo System Interface Foundation Driver - Necessary prerequisite (missing driver in device manager without it). It allows the Lenovo Utility and Lenovo Companion to work. Lenovo Yoga Mode Control - Necessary if you want to use your yoga to seemlessly change between all the different modes (laptop, tablet, tent, stand). This software is responsible for autorotating and putting Windows into tablet mode. Lenovo Utility - Recommended(?) This one I'm not too sure on. I remember that I was missing some function that I wanted but I can't remember what it was now. Maybe battery cycle count and health? Lenovo Companion - I don't have this one installed and don't think it's necessary but would like someone else to shed some light here.

Thanks for Posting!
 
First go inside BIOs by tapping F2 while turning on the computer.
    Then go to the Exit TAB and make sure that the OS Optimized and OS Optimization are selected to Other OS or Disabled.
     Then Go to Boot or startup tab Make sure that secure BOOT is disabled
     and Boot mode and Boot Priority is set to Legacy.
 
Now hit F10 to Save and Exit
 
Insert the CD and Turn the system OFF
 
Now when the computer starts up start hitting F12 (while the system is turning ON)
     You should have a boot selection  select BOOT menu or Select the CD / DVD
   
This should make the CD's load the Installation.

Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to the computer. 2. Remove the computer cover. 3. Locate the Clear CMOS /Recovery jumper on the system board. 4. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and pin 3). 5. Reinstall the computer cover and connect the power cord. 6. Turn on the computer and leave it on for approximately 10 seconds. Then, turn off the computer by holding the power switch for approximately five seconds. 7. Repeat step 1 through step 2. 8.

Yesterday, I clean-installed Windows 8 Pro x86 on an old Dell Vostro 1400 laptop which had been running Windows 7 Ultimate, and it activated and ran fine, without even a single exclamation point in Device Manager. I applied the update necessary to make the Store offer 8.1 and proceeded to install it as I've done on a couple other machines. After downloading the thing, it errored out with:

When I clicked the OK button, it then gave me the informative and grammar-challenged error box:

Something happened and the Windows 8.1 couldn't be installed. Please try again. Error code: 0xc1900104

Welcome to the Community Forums.
 
As per specifications, you can upgrade the RAM :
16GB max / PC3-12800 1600MHz DDR3L, non-parity, dual-channel capable, two 204-pin SO-DIMM sockets 
 
The graphic chip however is not upgradable since it is soldered on the motherboard.
 
Looking at the minimum specs of PUBG:
OS: 64-bit Windows 7, Windows 8.1, Windows 10Processor: Intel Core i3-4340 / AMD FX-6300Memory: 6 GB RAMGraphics: Nvidia GeForce GTX 660 2GB / AMD Radeon HD 7850 2GBDirectX: Version 11Network: Broadband Internet connectionStorage: 30 GB available space
 
It would be best to invest on a gaming laptop or better yet a desktop to enjoy the game.
 
Hope this help answer your query.
 
Regards

RELEVANCY SCORE 38.4

Hello! I know this question has been answered before but I do not know much about computers. I want to upgrade my graphics card from what is in it right now but I would prefer to have to do the least amount of screwing around possible. I am worried if I do very much I will reck my computer. What would be a good Graphics card for my computer? I have a budget of $150-$200. Please explain this as simply as you can. I have not done anything to the computer.

RELEVANCY SCORE 38.4

I recently purchased a Lenovo H30-05 but have now realised the Power Supply is not enough to support the NVIDIA GeForce 750 Ti (this would have been obvious if I had checked and found out  it was 65w before purchasing but, long story, I didn't). 
 
I'm wondering if it is possible to add an internal PSU which would cope (e.g. 300W+) as there is no 20-pin connector on the Motherboard? I see the 4-pin connector and obviously the socket where the power lead connects on the back but just wondered if a regular ATX PSU would suffice if I connect the 4-pin to the Motherboard?
 
Mod's Edit: Additional information added to Subject line for clarity of issue.
