Probably motherboard problems

post #1 of 3
Thread Starter 
Hey guys.

I have some serious problems for a long time.

Setup.
- Asus K53SV, i7 2630qm, GT 540m
- Dell 2312 full hd monitor
- Logitech M185 wireless mouse
- Logitech K120 wired keyboard

Problem 1.
Any mouses I connect to my laptop, they dont work normal. Sometimes I can feel some delay, lag or the pointer is inaccurate. This state isnt constant, sometimes it seems to be ok, sometimes it doesnt.
I tried changing batteries in my wireless mouse. I tried with my wired mouse. I tried without my external monitor. I tried installing newer/older drivers (intel hd, nvidia, realtek sound, realtek lan, atheros wlan) and reinstalling windows 7 several times. Nothing helped.

Problem 2.
Buzzing sound in my earphones. Sometimes it does it when I move the mouse, or when I move the screen (scrolling pages). Right now I am using a wired mouse and it produces this buzzing sound constantly, and its even stronger when I actually move the mouse. I tested it with 3-4 earphones/headsets.

Tests.
I tested DPC Latency, it is usually 400ps with DPC Latency checker. Sometimes the spikes go up to 3000 or even higher.
I read about usb 3.0 interference and wifi interference. Tried disabling both devices in device manager.

I made two videos with my wireless mouse some weeks ago.

In this video im trying to move the moues left-right, the same distance, but the camera randomly goes over sometimes.

In this video im trying to aim the two pillars. It was very hard with that accuracy.

Conclusion.
In my opinion, my laptop needs a motherboard repair/swap. The usb system is probably damaged, that could cause the mouse lag. The buzzing sound must be the sound card.
This laptop still has some weeks warranty. I already sent it to service a month ago, they did nothing but swapped the touch pad panel and the top case.

What should I do?

Roll back the video driver. At least 6 months.
