svchost.exe using almost all available random access memory after boot
Hello, I will start by describing the problem:
Whenever I start up this laptop, usually after opening Firefox I find that it keeps freezing by even hovering the mouse cursor over links, or UI elements. It turns out that the problem is an "svchost.exe" process that takes up to 800MB of my ram (out of 2GB) which is all I have available for programs. Other than that, it does have slight CPU usage - 5 - 15%. After about 20 minutes, the process calms down. This has happened three times just after booting so far (every time I booted this machine).
Here is some information about the machine itself:
Manufacturer & Model: Hewlett Packard Compaq Presario CQ70-211EM
Type: Laptop
Detailed specifications: Contact HP Support and Customer Service | HP® Support
OS: Windows 7 Home Premium x64
Some more information about what I did to the machine:
I erased the hard drive using DBAN in auto mode. Then, I re-installed Windows and installed all the necessary drivers. After doing so, I have installed all the "important" and "recommended" updates for Windows, except a few I didn't need. After installing and configuring some of my favourite programs that I would be using, this is where svchost really ruined my good mood.
I did scan the system with Malwarebytes after installing all the drivers and Firefox, in safe mode. I haven't downloaded or installed anything that could come with viruses/spyware. Everything was scanned ahead of opening it, and I haven't even plugged any drive I haven't checked to this machine.
This has happened before to me, on another machine and on my friend's computer. Apparently it's a normal thing that some service does, after installing the OS. Can't remember what it was though.
I was not installing any updates at the time it happened.
Screenshots:
I have included three screenshots. I couldn't quite capture it in Process Explorer when it was using 500MB+ RAM because it was too slow, I wasn't able to open it (PE) until it calmed down slightly.
- svchost shown in task manager using 500MB+ RAM
- same process and its services shown in Process Explorer (top of the list svchost screenshot)
- second svchost process and its services
I would want to avoid running anti-virus scans or installing any other programs for now, until all the less disruptive and intrusive solutions/troubleshooting methods have been suggested and applied.
I appreciate any help and replies I get, thank you.
