Blank icons/white thumbnails + slow My Computer

After some time on the computer the icons become blank and My Computer doesn't load.
It all returns to normal after I end the task "dllhost.exe", and after some time the problem comes back again.

I've tried these solutions:
- SFC /scannow
- Recreating IconCache.db

System:
Windows 7 Home Premium x64
Laptop - Toshiba Satellite P775
8GB RAM
Intel HD Graphics 3000
Mobile QuadCore Intel Core i7-2670QM, 2400 MHz

Thanks!

Hi,

If this issue started occurring after doing some recent software changes on your computer, then I would suggest you to restore your system back to a date when it was working fine. System Restore will affect Windows system files, programs, and registry settings only.

If the issue still persists, try running Hardware Diagnostics on the computer.

It's been going on for over a month so system restore is no option.
What Hardware Diagnostics do you recommend? (I think I've run them all...)
Thanks!

Hi,

I would recommend you to run Hard drive diagnostics. If there are no errors, then I would suggest you to try creating a New User account and then try to log in this New User account in Normal Mode.
If the issue still persists, you can even try restoring system back to factory settings and then check the performance of the system. Ensure backing up your data before reinstalling Operating system or PC restore.

The problem came up in the new user.

I'll consider restoring to factory settings.

This could be a infection. Some infections do hide in dll host.
What security programs are you using?
This is a good program to use.

Windows Defender Offline

Here is another one.

Free Online Virus Scanner | ESET

Throughout the years I've always been very careful and strict about that subject - and haven't had infections.
Currently I use ESET Smart Security + Immunizations by Spbot/SpywareBlaster/Advanced SystemCare.

As in most cases, formatting solved it (for now).
