For awhile, I've been getting some odd symptoms. After my computer is on for a certain period of time, usually several hours or so, system files just disappear, and I can't get anything done unless I restart. When I restart, a disk check is always performed. I'm not sure, but I think this started some time after I ran ComboFix to get rid of a nasty rootkit, which it did.
The first I noticed is when my internet gets rather glitchy and slow. I went to "repair" the connection, and I got this right away: "Failed to query tcp/ip settings of the connection."
I thought that was it, so I did some research from my iPod Touch on the file and when I went into the system to check and make sure the file wasn't a virus imposter, I couldn't find any of the system files. If I tried to run chkdsk.exe with a run command, it told me it couldn't find "chkdsk.exe." If I try to open task manager, I get an error that was something like this: "0xc000000142 application failed to initialize." If I recall correctly, I could not find any *.sys files at all, even when viewing hidden and system files.
All this happens if I am using the computer at the time of the problem. If not, I come back to the computer, usually with a "Bad Pool Caller" BSOD.
I have run a few different antiviruses but nothing comes up.
Something that baffled me to the point of coming to BC, was that I have repaired the OS with the disk (not completely wiped, just repaired) multiple times... I even uninstalled and reinstalled most drivers.
I've been bearing with it for awhile now, but I finally got sick of it when it failed while I was working on a project. I hadn't saved in several hours, and lost it all. I'm sick of it now.
Can anyone get me pointed in the right direction?
Here is some system information:
OS Name: Microsoft Windows XP Professional
Version: 5.1.2600 Service Pack 3 Build 2600
OS Manufacturer: Microsoft Corporation
System Manufacturer: LENOVO
System Model: 2743DGU
Once again, I'm new to this, so let me know if any info is needed/not needed.
