Hi, I just bought a brand new Lenovo ideapad Y700 and when I ran the hardware scan, everything passed except for the mathematical operations test for my Intel(R) HD Graphics 530 video card, which resulted in a failure of the hardware scan and a result code of WVC007002-UK7W7N.
What should I try to fix this issue?
Solved! Go to Solution.

I got this too with my Y700, it's down to the VGA driver rather than the hardware but it shouldn't affect any functonality so no need to worry about it. Hopefully Lenovo will issue a new driver soon to resolve it
If you don't want to wait I managed to solve it by installing the most recent driver from the Intel website, please note you won't be able to run this from the .exe download, you'll need to download the zip file, extract it, and then install the driver from device manager.

I fixed it as the others above have done. Full instructions:
Download the 64-bit zip file and extract it.
(Taken from the Intel installation readme)
1. Click "Start", right-click "Computer", and click "Properties".
2. Click "Device Manager" on the left.
3. In the "User Account Control" window, click "Yes".
IF UPDATING DRIVER GO TO STEP 5
4. Double-click "Video Controller (VGA Compatible)" if present under
"Other Devices". (Go to step 6).
5. Expand "Display adapters" and double-click the graphics controller.
6. In the "Driver" tab, click "Update Driver". (Letting Windows search automatically for the driver will not work - it will say you already have the latest driver.)
7. Click "Browse my computer for driver software".
8. Click "Let me pick from a list of device drivers on my computer". (This is the second option - the browse folder option on this screen will not work.)
9. Click "Have Disk..." and click "Browse".
10. Browse to the directory where you unzipped the file you
downloaded, click the "Graphics" folder, and select the
"igdlh.INF" file. Click "Open".
11. Click "OK" and click "Next". The operating system will install
12. Click "Close" and click "Yes" to reboot. The driver should now
I didn't need to reboot. You'll see the screen go blank for a second, and it will display again. Run the hardware scan on the Intel graphics card again and it should pass.

Intel. Edited my post as I was doing it wrong in step 8. Note that both doing it the wrong way (updating by folder), or using the Intel Driver Update Utility will falsely tell you that you are already using the latest driver.
The failed test bothered me because I just got the laptop last night, and after initial bootup I got a Windows error saying the Intel graphics driver failed to load, and an image on the Lenovo website was glitched out.
Since you mentioned it, I had to download and update GeForce Experience because the shipped version couldn't connect to NVIDIA to download the latest game ready driver.

Yep same exact thing happened to me when I got it a week ago. I download the nvidia driver off their site, now the software works fine, must be a Windows 10 thing.

I have this problem.This is critical? Problems with graphics only in Microsoft Edge,screen/display flashes or blinks intermittantly.

What is the name of their hardware scanning software?
I tried Lenovo Solutions and Lenovo Diagonistics... can't seem to find. thank you!!
And yes, I am having this Mathematical Operations Error with my new Lenovo Ideapad Y700 too!
Also I notice there is a video lag when I connect my HDMI to my 40'' vizio hdtv. I hope this patch resolves it
