No monitor signal or mouse and key board

[steelindian66]

My computer is a Asus i5 core [g11cd -wb51] My son would hit up against the desk while sometimes when playing a game the screen would freeze and a loud buzz noise would play I assumed a loose connection so I opened my computer unplugged everything a and replugged it everything back in hooked up all of the cowards I had hooked up and booted up the computer the graphics card lights up and I hear fans running the monitor says no connection my razor mouse nor Logitech keyboard receive any connection not sure what the issue could be now

Welcome to Tom's!
I suspect that when you unplugged everything and replugged it, you didn't get EVERYTHING plugged back into its correct place, or polarity.

I am fairly certain that everything is plugged in properly the cables were ziptied near the ports and had mostly notches they popped over the only plug I was iffy on was the disk drive that was because there were two very similar plugs that connect to the mother board near it so I I wanted to get a solid state I tried both and no go I'm not so sure what to do about polarity I'll Google that when I get more time later
*edit sorry if I sounded like a jerk above was not meaning to come off that way and I held the power button down for 45 seconds with nothing plugged in and rechecked all the wires it still does not work

" the screen would freeze and a loud buzz noise would play". This sounds familiar. It is highly unlikely to be caused by a loose cable. Is your CPU overclocked? Another issue which could cause these symptoms is RAM issues and underpowered or dying PSU. You could get a simple PSU tester for under $15 such as one here: https://www.amazon.ca/HDE-Power-Supply-Tester-PCI/dp/B005UZHB6G/ref=sr_1_2/136-1456820-3454817?ie=UTF8&qid=1516692162&sr=8-2&keywords=psu+tester This is a very useful tool to have around, much faster than using a volt meter.

Not sure why someone mentioned polarity unless you also unplugged the power leads from the case buttons to motherboard. Did you also unplug those? Are they separate 2-lead plugs? If so - refer to your motherboard manual for instructions on plugging those in properly. As for the PSU plugs - you don't need to worry about polarity as they can only fit into the motherboard one way. They would require considerable force to plug in incorrectly somehow, and is unlikely.

Are there any loud beeps when you try to power on the PC? What you may also need to check is that the RAM modules are properly seated as well. Pull them out if you have to and put them back in until each latch at the side clicks and closes. Make absolutely sure both of your 6-pin connectors for the gaming card are plugged into the card all the way. Also make sure all other plugs from PSU (Like 24-pin, 4/8 pin 12v rail) are firmly in all the way. If the case is dusty inside - wouldn't hurt to use compressed air to clean the motherboard before plugging all the wires back in.

Let us know how it went. Once your PC is powered back on and running - look into Prime95 program for testing your CPU and RAM. It's best to run the program for 24 hours, but if there are serious issues with the CPU overclocking, etc. - the test will fail within minutes or you would get a BSOD. If so, - write down the error message and post it. Or when the Windows boots and posts an error message - make a screenshot and post it here or copy the message and post it here. Also wouldn't hurt to run a memtest. I wish you best of luck.

Ya from what I had read elsewhere I was kind of thinking it could be ram issues I just have to wait a bit to have money to test things out and see I did not unplug the connectors to the case I wasn't having issues turning the computer on so I did not bother with those no loud beeps accur I'll try the other things you mentioned after work
