Windows 7: Win 7 keeps freezing, increases memory usage then reboots itself

Win 7 keeps freezing, increases memory usage then reboots itself

Hi,

Firstly, I have searched many thread and found similar but not exactly the same symptoms, and tried a number of the suggested remedies. However, I'd like to list all symptoms here and ask advice. It is possible there are multiple issues at work (e.g with Firefox and with sound playback) so my apologies for appearing to be an idiot

1. Recently Win 7 kept giving me a "memory almost full" error, and occasional freezing. I did the normal memory tests and full hardware tests, nothing showed. As I am not on auto update I did a manual Win 7 update. Did not solve the problem. Any app I am running (including Windows Explorer) is prone to freeze for several seconds, yet Resource Monitor shows a lull in all activities (i.e. HDD, memory and CPU), the CPU usage shows as 0-2% but nothing happens. In these cases Firefox shows a "not responding" message.

2. I ran ESET which came up with 2 instances of "a variant of Win32/Adware.Yontoo.B " both of which were deleted, but the problem persists. I have Kaspersky installed, with auto updates and daily scans, nothing shows. I ran Malwarebytes, nothing shows.

3. I did the BSOD check and downloads (now in a ZIP file), also made several screen captures of Task Manager and Resorce Monitor at various stages (first logon, with 1 app running, after one of these freezes) in a Word file, but each time I try to upload them on here, individually or together, I get a Time Out error.

4. Possibly unrelated, I am not sure, but since this started any sound playback (whether a media player like GOM, Windows etc.) or online streaming, is intermittemt, i.e. sound runs a few seconds, then silence a few seconds, then sound again etc.

Many thanks in advance for any help you can give

Philip

Whoops, sorry, I suppose I should add system info too :

Asus X52F Laptop(K52F/K62F Series) with Intel Core i5 M480 2.67GHz 2.67GHz
4GB RAM (3.79GB usable) 64 Bit Operating System
Windows 7 Home Premium with Service Pack 1
Windows Experience Index 3.9 (not sure if that is relevant)

Anything else I should add?

Philip,

Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec
(left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Manufacturer and Model and
ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

You will find that in Speccy, you can select info from the display
using your mouse/touchpad and then paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

golden,
I provide a link to the SF aid, however, that aid does not supply some key info which is why I recommend the other tools.

Very many thanks Golden and Karl.

I have updated my profile with system specs as advised; installed and run CCCleaner, 3 files attached (I hope - the Manage Attachments window keeps freezing with the "not responding" message). It seems that my computer is getting slower and the freezes more frequent and longer lasting

Thanks again

Philip

REMOVAL OF P2P PROGRAMS

There are signs of one or more P2P (Peer to Peer) File Sharing Programs on your computer.

As long as you are using any form of P2P networking to download files, you can anticipate malware infestations.

References citing the risk of using P2P programs:
How cyber criminals infect victims via P2P with pirated software on Vimeo
Malware: Help prevent the Infection
Perils of P2P File Sharing
How to Prevent the Online Invasion of Spyware and Adware
The Hidden Security Risks of P2P Traffic


I strongly recommend that you uninstall:
µTorrent
BitTorrent
Vuze

=============================================

I'm not even going further until you get an opportunity to carry out following since you have been using p2p software and your install list shows some cracked software.

I have many other programs to be uninstalled, but first i need you to carry out following procedures. Then and only then will I be able to continue.

HOW TO USE WINDOWS DEFENDER OFFLINE ON A USB STICK
Windows Defender Offline
· is a free standalone, bootable malware and virus remover from Microsoft.
· performs an offline scan of an infected PC to remove viruses, rootkits and other advanced malware.

Download Windows Defender Offline (about 764 kB)

You will have the choice of downloading the 32bit version (x86) or the 64 bit version (x64).
The link will help you determine whether you are running a 32 bit version or 64 bit version of Windows

NOTE!! You can download and prepare a 32 bit version using a 64 bit version of Windows
NOTE!! You can download and prepare a 64 bit version using a 32bit version of Windows.

You run the 32 bit version on a 32 bit version of Windows.
You run the 64 bit version on a 64 bit version of Windows.

The 32 bit download file name is: mssstool32.exe
The 64 bit download file name is: mssstool64.exe

For the curious, this program was originally name Microsoft Standalone System Sweeper.


INSTALLATION:
You will need an Internet Connection.
Insert 512 mB (Microsoft’s 256 mB is no longer accurate) or larger USB stick into a usb port.
Run the downloaded program--mssstool64.exe or mssstool32.exe
NEXT button
Choose the option On a USB flash drive that is not password protected
NEXT button
NEXT button
.
The install program will format the usb stick using the NTFS format.
The install program will download about 210 mB.
The install program will name the USB stick WDO_Media32 or WDO_Media64
The WDO_Media32 usb stick will have used space of 255 mB (268,140,544 bytes)
The WDO_Media64 usb stick will have used space of 282 mB (296,165,376 bytes)
You can expect the number of mB to increase as more malware appears.

UPDATE Windows Defender Offline USB stick:
· reinsert the usb stick
· run the installation program, mssstool64.exe or mssstool32.exe, again.
· the update will download about 66 mB (mssstool32.exe) and 68 mB (mssstool64.exe).

Since the malware database is sometimes updated several times in a day, always update before running.

PERFORM AN OFFLINE SCAN
Bootup your computer from the USB stick
Windows Defender Offline will automatically perform a quick scan.
After the quick scan finishes, Choose Full Scan
Select all of your drives

The initial, full scan can easily take several hours, but
Remember, your computer is being very thoroughly checked for all types of malware.


RESULTS OF THE SCAN
The results will be in 4 log files on your computer's disk in:
\Windows\Microsoft Antimalware\Support
===========================================
===========================================

I will await the following .ZIP file.

Hi Karl

Firstly, this is turning into a nightmare! My computer is now hanging up for around a minute or so every 2 or 3 minutes. It has frozen twice already even in this brief message. Anyway, I have uninstalled BitTorrent, I do not have the other 2 as far as I am aware (cannot find them), and rebooted. As for Defender Offline, I have downloaded the .exe file but when I try to install, on USB, DVD even ISO file (as suggested on the MS website) it hangs at 190.12Mb of 190.82Mb and after a couple of minutes returns an error. I have been trying every option and hitting retry, rebooted my computer twice, used 2 USB sticks and 3 DVDs, same error each time. I even tried another laptop, same error on there too (with both USB and DVD).

Any ideas please?

PS I tried a cold restart, the d/l was then 221.82MB, reached 220.12MB and hung, on retry it reverted to 190.82MB and hung at 190.12MB
