I have a HP Envy dv6 running Windows 8 that is around 2 weeks old now.
Every now and again the computer becomes very slow and when I check 'Task Manager' it show 100% Disk Usage.
The task at the top seems to be different each time. After a few minutes it usually goes down again and works as expected.
After some Googling I installed all windows updates and HP updates via HP support assistant but it didn't seem to help.
Somebody also recommended uninstalling Norton antivirus and using the built in Windows Defender. That also hasn't really helped.
I also tried using the 'Refresh PC' option to reinstall a fresh copy of Windows.
This has been happening since the laptop arrived. Is there anything I can do to fix this or do I have to return the laptop for a new one?
Also when I boot up the laptop it takes quite a long time to load for a new computer. It hangs on the black screen just after the HP logo is displayed for around 30 seconds, is this normal?

In order to know which process is utilizing the Hard Disk on Windows 8, I would suggest you to try the following steps.
a. Open Task Manager and click on Details tab.
b. Right click the columns headers and click "Select Columns".
c. From the "Select Columns" window, check: I/O Reads, I/O Writes, I/O read bytes, I/O write bytes and then click OK.
d. Now the columns will be added to the view and will display how much each process is utilizing from the hard disk.
e. Sort by I/O read bytes or I/O write bytes by clicking on the column header to see which process is utilizing the HD most.
Try the following methods and check if it helps.
I would suggest you to increase this virtual memory and check if it helps.
Windows8 automatically manages virtual memory and paging file size by default. The virtual memory set by default is approximately 70% of the recommendation.
You need to increase this virtual memory. Make it equivalent to your RAM size for the initial size and twice of the initial size in maximum size and make sure you have the same amount of free space in your hard drive in each drive.
a. Press windows + R key from the keyboard.
b. Select the option Control Panel and All control panel items then System.
c. Click on Advanced system settings.
d. Under performance, click on settings.
e. Go to Advanced tab, Under Virtual memory, click on Change.
f. UN-check "Automatically manage paging file size for all drives" check box.
g. Select your windows drive (where OS is installed).
h. Click on Custom size radio button.
i. Set Initial size equivalent to your RAM size in MB.
j. Set Maximum size to twice of your RAM size in MB.
k. Click on Set.
l. Click on OK thrice.
m. Restart your system.
I would suggest you to boot the computer in Safe mode and check if the issue persists.
Safe mode starts Windows with a limited set of files and drivers. Startup programs don't run in safe mode, and only the basic drivers needed to start Windows are installed.
If the issue does not persist in safe mode, then perform a clean boot to check if any third party application is causing the issue, as clean boot helps in eliminating software conflicts.

Note: Once you are done with the troubleshooting, perform the steps in “How to reset the computer to start as usual after troubleshooting with clean boot “to reset computer as usual.

I also tried everything I could find on many different forums to fix this and nothing worked. Lo and behold when I was getting ready to return my new laptop I popped the SD card out of the slow and bam, disk usage shot to 0%.
Seems like a weird cause to me, but it worked for me.
