I can't figure this one out...

 

It seems explorer and other programs stop responding after about 15 minutes of inactivity. (I cannot ctrl alt del or anything)

 

I disabled all optional services and start up programs via msconfig

 

I changed my hard drive to not spin down on inactivity and not go to sleep

 

 

 

If I have a chrome window open (say gmail) I can continue to open emails and even retrieve items and receive new emails - but I cannot open a new tab, and if I try to redirect to a new website at the bottom of chrome it says "waiting for cache"

 

 

It seems like a hard drive or l1 cache type issue - but how do I diagnose further?

 

There is nothing in the logs that seem to be useful...

 

 

any suggestions?

Because I don`t know what is this - Null-modem emulator (com0com) (Version: 3.0.0.0)

com0com is a free utility to create virtual serial port pairs which can be used to capture the debug output of ReactOS and direct it to a terminal program.
 It will automatically install a pair of virtual COM ports "CNCA0" and "CNCB0" that are linked by a virtual null modem cable.
You can optionally change the names and edit the settings with the gui setup tool (setupg.exe). In this example they are named COM4 and COM5.
IMPORTANT: After that, click on Apply. Windows will detect "new hardware", click on Next and let Windows find and install the "com0com serial emulator" hardware.
You are done.Connect the Virtual Machine to your first virtual port ("COM4") and the terminal application to the second ("COM5").
The properties of the serial port (usually specified in the virtual machine), like the baud rate, are not important. Instead, be sure to select "NO FLOW CONTROL", because otherwise the terminal app won't receive any characters.
The virtual machine shows a COM1 port to ReactOS which is used for sending debug messages.
The virtual machine maps this port to a virtual port visible to the host operating system.
com0com emulates a null modem cable between the vm and the terminal application.

It`s critical situation.There is a little space.

1 Drive c: (OS) (Fixed) (Total:605.66 GB) (Free:16.55 GB) NTFS
2 Drive d: (Data) (Fixed) (Total:651.93 GB) (Free:9.26 GB) NTFS

Reinstall this - Microsoft Visual C++ 2005 SP1 Redistributable Package (x86)

http://www.microsoft.com/en-us/download/details.aspx?id=5638

 

I didn`t see you antivirus program have.

com0com is a program that allows for virtual serial ports - used for development (no concern)

 

 

what does little hard drive space have to do with this?

 

Sure I need more space - but that should have _nothing_ to do with a computer becoming unresponsive

 

 

c++ redist. do not need installed on development machines (I have visual studio installed and they take care of c++ compilations and linkage)

If there is a very little space remaining free on hard drive computer doesn`t feel comfortable.

Also:

Row: 1 - 4096 MB PC3-12800 DDR3 SDRAM Kingston
Memory Speed:800.0 MHz
Row: 2 - 2048 MB PC3-10600 DDR3 SDRAM Samsung
Memory Speed:666.7 MHz
Row: 3 - 4096 MB PC3-12800 DDR3 SDRAM Kingston
Memory Speed:800.0 MHz

The second is different.I recommend to set all of them to 666.7 MHz/1333Mhz/

I am not going to argue.You have it on your computer:

Microsoft Visual C++ 2005 Redistributable (Version: 8.0.56336)
Microsoft Visual C++ 2005 Redistributable (Version: 8.0.61001)
Microsoft Visual C++ 2005 Redistributable (x64) (Version: 8.0.59192)
Microsoft Visual C++ 2005 Redistributable (x64) (Version: 8.0.61000)

You have problem with this - Null-modem emulator (com0com) (Version: 3.0.0.0)

Something is out of place.I don`t know why.

We are here for help and to learn something useful not to judge.

Windows is unable to verify the image integrity of the file \Device\HarddiskVolume3\Windows\System32\drivers\com0com.sys because file hash could not be found on the system. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

So you don`t have an antivirus program and it might be a virus and actually the problem is not in Null-modem emulator (com0com) (Version: 3.0.0.0)

I was asking just out of curiosity and to better understand this in the future as to why you suspect com0com - not saying you were judging just wanting to understand why

 

I appreciate the help on the matter!

A recent hardware or software change - so hardware change is related with harddisk,software change has been done by you or something you don`t know.

Also I am not curious what kind of software you have.
