I have a lenovo thinkcentre m91p and want to connect to a older flatscreen Toshiba via a VGA cable and an audio cable?

The tv has the vga recepticle as well as the audio jack that l have connected to the tv, l plugged in the VGA to the rear of the Lenovo M91P desktop and the audio cable to either the audio jack at the rear of the computer or the jack on the face of the computer for the headphones. With this setup l am receiving the video to the tv but absolutely no sound from the tv. The headphone jacks on the computer work with my headphones but not with the tv. What am l doing wrong?

Can I play the sims 2, sims 3, and sims 4 on this?

Hi! So i want to buy a desktop to play my sims games on because playing on a laptop is making it really laggy and basically unplayable.
Would this desktop work? https://www.elgiganten.dk/product/pc-tablets/stationar-pc/ACDGE0DEQ016/acer-aspire-gx-281-stationar-gaming-computer or maybe this one https://www.elgiganten.dk/product/pc-tablets/stationar-pc/LE90JB003CMW/lenovo-legion-y520-tower-stationar-gaming-computer

Question about upgrading my Lenovo desktop tower's graphics card?

I'm having a little trouble finding an answer to this on Google. Hoping someone can help me out.

I have the "Lenovo ideacentre 720-18asu" tower, Model Number is "90H10004US". It has the Radeon RX 560 (4 GB) graphics card, and according to the Command Prompt, the motherboard is a "Lenovo 3100". I'm just curious if anyone can tell me what the best graphics card is that the aforementioned motherboard can handle?

Can I take the parts of a pre built small form factor pc and put it into a new case?

I want to build a pc and so I'm considering buying this:
https://www.reboot-it.com.au/p/Used-Computers/Core-i7/Lenovo-ThinkCentre-M82-SFF-i7-3770-3.4GHz-4GB-500G/26562
and upgrading it with some better ram, a new case, an SSHD and a graphics card from external sources. I want to know if it is possible to open it and take the parts out and put it into a new desktop. I've taken apart and put together ordinary desktops before but nothing quite like this. I just need to know if the parts are required to be in that case. (also… I do know it would void the warranty but I don't really mind).

Recommend computers that have the following specifications?

Windows (minimum requirements)
Processor Model: Intel i5 650
Processor Speed: 3.20 GHz
Memory Standard: DDR3-1333/PC3-10600
Processor Type: Core i5
Memory: 8GB
Operating System: Windows 7 SP 1 or higher
Monitor, 19"-22" LCD
Video Card: capable of supporting Dual monitors
Sound card with compatible USB connected headset
At least two (three preferred) available, unused USB ports

I can find many of these but am confused mainly about the Memory Standard and Video Card components. I'm not knowledgeable enough to know if for example a lenovo thinkcentre would meet these requirements. I would like recommendations for computers that do meet these requirements.
