hi all,
I have an Asus X550CA laptop running Windows 8.1 and this thing has recently developed a habit of freezing whenever it feels like it. I mean there's no pattern to when it freezes. Nothing works, the cursor stops, if there was a windows animation occurring it just stops midway. None of the keys work so I can't do CTRL ALT DEL. Oddly however, it never freezes whenever I'm running a game on it, ever. For example the last couple of times it froze were right after I pressed the WINDOWS key on the keyboard, plugged in an iPad via usb and a couple of times randomly watching YouTube. One time it froze and a couple of minutes later gave me a blue screen saying WHEA_UNCORRECTABLE_ERROR. I searched this up and apparently that's caused by corrupted system files. So I went into the command prompt and typed 'sfc /scannow' then pressed enter as suggested by someone. The checkup reported no corrupt files or problems. Someone please help me. I have no clue what this is.

Edit: this thing has been frozen for the past 30 mins now and NOTHING is happening.

Honestly no one has any other ideas as to what may be causing this? Oh and I noticed btw, that even while sitting at the desktop doing nothing, speed fan showed a cpuusage of 40-50%. Upon opening the task manager, I discovered that Windows explorer was using 20-30% of my cpu. I found this thing called Process Hacker and downloaded it. It shows you, in depth, what everything is doing. Clicking on Windows explorer I found this thing called twinui.appcore.dll using most of the CPU, I terminated it and after that laptop ran quick n cool as before. However, that thing shows up every time I start the laptop up. I don't know what it is and apparently terminating it doesn't cause any harm to the functioning of the laptop.

It could be malware

1.Download malwarebytes, boot into safe mode with networking, run a full scan from there

2.If you are using a HDD, not an SSD, download defraggler from piriform and defragment your hard drive

3.Open msconfig, go to the startup tab, disable only the startup programs you absolutely 100% sure do not use

4.Update windows to the latest version

5.None of the above helps, run memtest86 to make sure your RAM is ok. Crystaldiskinfo will also check the health of your hard drive

Right, so far I've run memtest for 22 hours with no errors, run malware bytes twice, the hard drive is "healthy" with a temperature of 37C. The cpu temperatures were 56-60 while sitting on the desktop before cleaning the laptop fan (there was a little bit of dust, the machine is only 6 or so months old). I haven't checked cpu temps after cleaning.Windows is up to date. I've tried the laptop using the battery and without using the battery (plugging it in directly using the charger). The laptop now, instead of freezing 5 times a day, freezes once a day. But it still does it. I've noticed, before freezing now, it'll get really laggy as opposed to the completely unexpected freezing before. The fan will seriously kick up as well. Touching the base of the laptop doesn't seem particularly hot. In fact the laptop is frozen right now. The only thing I haven't done is to defragment the hdd.

As I've already said in my previous post, I have cleaned the laptop out. I removed the covers, cleaned the little fan, all vents and there was a copper pipe running from the fan to the motherboard, I blew dust off that as well. I can't just buy and use a cooler. The laptop was running fine before and I wasn't using any type of cooler. I'm sure it can do that again.
