I'm having trouble understanding what is going on with my work PC. Whenever I boot it, it runs fine for a while, then starts to randomly show disk errors. The displayed error often contains the message "not enough storage is available to process this command", although depending on the application that fails it can be different. This has happened for weeks now and is getting worse.
This is what troubles me:
- It never seems to impact critical parts of the system (no BSOD, no freeze).
- Only some applications seem impacted, refusing to function correctly after a while: Outlook 2010 cannot download RSS feeds anymore, Firefox 6 or IE9 cannot download anything bigger than 3MB without failing, Windows Update fails, all msi installers fail, Visual Studio 2010 starts failing in weird manners...
- It only happens after a while using it (typically 3 hours, but it seems that installing a program or compiling several times makes it shorter)
- Rebooting solves it (temporarily).
- The OS is Windows 7 Pro Spanish SP1, 32 bits
- The system is an HP Compaq 6000 Pro with 4 GB memory (only 3.4GB usable since the system is 32bit), one 500GB hard drive.
- Installed applications include: Visual Studio 2010, SQL Server 2008 R2, VMWare Workstation 7, Microsoft Security Essentials, Office 2010. Shutting down all related services and processes doesn't seem to change anything.
The diagnostics I've run so far:
- Hard drive : 465GB, 165GB free
- Process Explorer : physical and virtual memory seem ok (pagefile is 5.3GB, physical memory usage 70%, system commit 39%)
- Windows Memory diagnostic tool: OK
- CHKDSK returned:
488282111 KB total disk space. 281668248 KB in 265779 files. 150188 KB in 62949 indexes. 0 KB in bad sectors. 571755 KB in use by the system. The log file has occupied 65536 kilobytes. 205891920 KB available on disk.
For non-spanish speakers, that means all ok.
- SMART diagnostic tools (DiskCheckup) report all values normal.
- temperatures are in the normal range (HWinfo).
- The event viewer doesn't seem to contain any significant message.
- ran CCleaner 3, without any noticeable effect.
I was thinking about some file number limit (between Visual Studio projects and other applications, there are around 300.000 files on the hard drive), but I couldn't find any. It's possible there is something related with the use of the temporary folders (it's the only explanation I have for why applications fail but Windows doesn't), but I cannot confirm that.
Only thing I cannot find out is if chkdsk reporting 65MB for the log is normal. It seems since Vista it always reports this.
Any other cleaning/diagnostic tool you might know of?
Edit: I ran several other tools since I first published the question:
- Seagate SeaTools (the HD manufacturer's analysis tool): complete test run OK.
- Intel Rapid 10.1 (the HD controller manufacturer's troubleshooting tool): the HD's ok.
- Microsoft Desktop Heap Monitor:

Edit 2: I tried totally resetting my account by creating a new one, logging under this new one and delete the first one (local rights and files), then logging back with this deleted account (it is a domain account). No luck.
Also, I found out often the error is "not enough storage is available to process this command". Searching on the internet, I found an old troubleshooting tip (setting a registry key to raise the IRP stack limit, whatever it is) which did not change anything.
