Hey everybody! Hope you're doing well :D
I've recently bought a new graphics card, thinking that it would fit into my small pc. It didn't, so I took my psu, cpu, hard drive and ram out of the pc and put it on another motherboard and case which has more room. However, although everything is working good, the mouse and keyboard randomly stop working. The light for the mouse is working but it's unresponsive! I can't see lights when pressing cap lock, num lock and scroll.
The RAM is from 2 different makers, I read somewhere that you shouldn't do this. Is this why this is happening? Do I have to reinstall drivers for a new motherboard? Thanks in advance guys!
 
Solution
All I can suggest is play with the temps to find out what they do. Usually the full load temp is the temp at which the fan spins up to 100%. The idle temp is usually the temp that the system trys to keep the system at. BUT this is what they usually do and no guaranty that it is the same on your system.
when swapping the motherboard did you do a fresh install of the OS?

IF you have usb 3.0 make sure your keyboard and mouse are plugged into usb 2.0 ports.

IF the system is locking up then I would suspect the ram but you did not say it was locking up just the mouse and keyboard is unresponsive. Be sure the system is not locking up.

to test to see if it is a ram issue get Memtest86+ and run it at boot. This program has its own interface and does not use windows. run it as the boot disk. run it for 6-11 passes not percent (%) but complete passes. this will take a few hours to complete.

Thank you for such a fast reply!
I can't do anything now, it's late. I shall try. Memtest tomorrow. I did not do a fresh install of windows 7, I thought it would prompt me to insert the disk or whatever, I just left it because it didn't.
Could you please explain what you mean by locking up?
Thanks again!
 
Locking up = freezing, completely unresponsive.

Any time the motherboard is changed to a different make and/or model the OS should be reinstalled. the only time you don't need to is when you are putting in the same exact model board. Not doing so can cause issues like you are experiencing and more. Try the basic things and test like I mentioned before going to the extreme of reinstalling the OS.

Alrighty! Will do! I don't think anything was locking up, no. I was midway playing a game one time and it was still running normally, just the keyboard and mouse. This may seem like a stupid question, would I lose all of my work/data if I did a fresh install?

So a friends uncle was in town for a day and he ran the whole memtest thing, and something else to check the memory. He had put in new RAM, 2gbx2, however there is still the same problem. So should I just reinstall windows?

I've also noticed my cpu goes up to around 90 degrees Celsius while playing.. I think this is when it stops working.
I've even tried reapplying thermal paste.

If the ram tested fine or is fine now, then yes reinstall the OS. Be sure to back up all data you want to keep and then format the disk. after reinstalling the OS, install the mother board drivers from the motherboards web site, then install the GPU drivers and keyboard and mouse along with any other peripheral drivers needed.

I'm actually getting quite worried now.
I've done all of that. My cpu is constantly around 80-90 degrees Celsius.. I've realised this is when it turns the mouse and keyboard off.
I will reapply thermal paste tomorrow, and I'll see how it goes from there. Any tips or anything?
Oh and I've also tried from the power options, an option which turns off USB's when it uses a lot of power. Thanks again, please try your best :p I'm getting all panicky.
 
OK be sure the program you are using to check the temps is reading the temps properly. Do this by using different monitoring programs and seeing if they are all close in temp. I like using HWmonitor from www.CPUID.com

Once you are sure your temps are high then make sure your Fans are working properly. Speeding up when they need to. If the fans are speeding up then reapply the thermal paste.

When you remove the heat sink be sure to clean it. wipe off all of the old thermal paste from both cooler and CPU. I use a coffee filter and Isopropol Alcohol, as high of alcohol content as I can find. I wet the coffee filter and rub away the thermal paste. Before applying the paste be sure both surfaces dry and lint free. Next on the CPU put a small pea size dab of thermal paste. Put the cooler on the CPU and in a circular motion spread the thermal paste around the CPU, be sure not to lift the cooler off the CPU. Then center the cooler and attach the locking clips and tighten the cooler down.


Quick recap: 1. make sure your temp monitoring program is accurate.
2. make sure the fans are spinning up to full speed. IF not then this is art of the the issue.
3. if all others fail then try and reapply the thermal paste in the manor I mentioned.

Thanks for the quick reply, I've seen the temp in the BIOS and a program "speedfan" where I keep the fan rpm 100%.
With the whole alcohol thing, I normally just use a tissue to clean it away, until I see no more thermal paste. Does it really make a difference? Thank you once again.
 
Yes it does make a difference. The purpose of the paste is to fill in the microscopic imperfections in the metals. If you do not clean the mating surfaces properly the new thermal paste will be to thick and not work properly. Tissue will leave behind lint were a coffee filter wont. Most people have coffee machines in the home so I find this a good substitute that is easily obtainable for almost anyone.

All I needed was a better fan and better thermal paste technique! Thank you for you help. I now idle at 40-50°C!
However my fan is pretty damn loud. Speedfan doesn't seem to change the speed of my cpu at all, and yes I do have a 4 pin connector.
Do you recommend me turning on "SmartFan" in the BIOS? My fan is like at 100% which keeps it at these low temps. Should I keep it noisy? Thanks.
 
If you want the system to automatically adjust the fan speed then Yes turn on "smart fan".

The two temp settings are so you can tell the system at what temp it should speed the fan up to 100% and when to lower the fan speed to try to keep it at that temp for idle.
 
OK then lets look at other causes for it being so hot. Do you have a rear exhaust case fan? possibly even a front? These are important for bringing in fresh air in to the case. Also try uninstalling speedfan and retry the smart fan to see if it will speed up the fan with out speedfan trying to control anything.

Have you cleaned out the dust from the CPU cooler? I would imagine you have but this will cause the cooler to not be as efficient. Just use some compressed air to blow it out. If there is any dust bunny's in the system clean them out too. Also be sure the air intakes are clean so fresh air can freely enter the case.

Make sure all the wiring in the PC is tucked as far out of the air flow path as possible. Air flow path is from bottom front to top rear of the case.

Have you OCed the CPU at all? or maybe adjusted the CPU voltage up? These create extra heat.

Be sure all case fans and PSU fan are working properly. Some prebuilt systems use the PSU fan as an exhaust fan. This is not a good way of doing exhaust but works under ideal conditions.

I do not have a case fan no, and I don't think speedfan is affecting it because I look at the BIOS temperatures.
There is no dust in the cpu cooler, that is for sure.
The wiring could be a problem yes.
I have not overclock or increase voltage.
And all of my fans are working properly.
I'll check the wires when I come home tonight, thank you for your fast response.

My case is really basic! It has no places that I know of.
And I'm really unsure about the smart fan temps, I don't get it, do I set them to be high or low? Sorry if this seems noobish, could you recommend the settings please?
 
All I can suggest is play with the temps to find out what they do. Usually the full load temp is the temp at which the fan spins up to 100%. The idle temp is usually the temp that the system trys to keep the system at. BUT this is what they usually do and no guaranty that it is the same on your system.

Alright so I set the full load temp and idle temp, however it doesn't change a thing. I set it to:
Idle:50
Full load:70
However it passes 70, and doesn't change the speed (1500rpm).
