Windows 7: "Something" blocks processes while writing to disk

"Something" blocks processes while writing to disk

I think of me as a computer expert and I believe this is a very though one (I'm planning to scratch Windows, in facts), but I have a last hope asking here!

The problem is: there's "something" that blocks processes while they're writing to disk.
The effects showed are, for example:
  • the kaspersky internet security breaks during updates and suspend itself saying the virus base is broken
  • download in chrome stops halfway
  • Adobe Lightroom (which uses a custom sqlite db) breaks during operations, saying the catalog is corrupt and attempts recovery at restart (operation that can break, too)
I tried disabling windows defender that in other occasions showed to lock files, but with no success.
I noticed that in Safe mode operations seems good.
I used ProcExplored to see if there's any process using CPU during this breakups, but didn't find anything; I also looked in the open handles to find other processes using the same file as the breaking ones without luck.

I don't thing it to be a virus as I have AV protection and tend not to expose PC to malware.

I also notice that this behavior mainly happens a few minutes after boot and then seems to disappear after other several minutes.

Does anybody have clues on what's happening or on how to find it out?

Thank you very much!!

Hello pdario as a long time KISS user mate I would uninstall and reinstall something has probably corrupted the system there.

Just save the trial to downloads use the unistalled from the Start Orb and reinstall from the Downloads and activate with your code but I am guessing I telling my grandmother to suck eggs but that is where I would start.

I know it is a pain but there have been a few bugs in KISS juts lately.

A sfc and chkdsk would not go amiss but again I guesing you ahave already tried these if you are ok at this stuff.

Noo!! I didn't even think of an hardware failure!! No panic, no panic!!!

Ok, I'll go for the sfc and chkdsk checks and still hope it's a sw problem.

About KIS: I also tried suspending and stopping it; I will also try a reinstall, if you think it could be the cause (I thought that it is something below it, as it is itself broken).

Pdario I personally don't like Chrome but whatever floats the boat. That isa strange symptom for KISS though and no mate a reinstall sounds like it mightbe in order.

Now you know you have the two main options one in the Start list which Ipersonally don't like although it does save your config of the program there isthe uninstall tool from Kaspersky

I don't know how you config the KISS I use my own which I got from anothersite but it has been removed but if you want a hand through - ask.

But first run these they will find stuff that any AV can miss
download the ADW from bleeping computer

If you are going to reinstall 7 then it looks like the chipset supports 64bit and there are options for you. A factory default (32bit) this USB Windows 7 Installation Key Drive - Create use the ISO and the activation code from your machine sticker or just buy and install a 7 OEM that would get rid of all the bloatware.

The sfc and chkdsk are not really hardware related mate they just check the OS filing sytem and try to correct problems.

Another check you could do is a temp check with Speccy Speccy - Download download from piriform and see what the temps are they can cause problems.

and a memtest if needed though this takes some time to do and needs at least 8 passes.
Memtest86+ - Advanced Memory Diagnostic Tool download and make a bootable stick or disk and set the BIOS to boot from the optical drive and let run.

Then if all this fails start in this Troubleshooting Steps for Windows 7 you will have done some already.

Thanks for suggestion. When I mentioned HW I was thinking of bad sectors, that sounds plausible...

I tried sfc but it said it cannot run after getting to 28%.
I tried windowed check disk selecting bad sectors check, it complained it couldn't run and set a boot scan.
I rebooted but nothing happened, so I set the disk dirty with fsutil and rebooted; it is now scanning for error, but it says is going through 5 steps which will exclude sectors scan.

One thing I noted before rebooting is the Crypto Service taking almost 50% CPU (basically a full core) and a LOT of ESENT errors in the Windows logs (saying it cannot read or write some files), but I don't know if this is a cause or an effect.

If I'm able to find out the disk is good, I think I'll go for 7 reinstall, so to retake my last GB of RAM that now is hidden by the graphic memory.

Maybe try those in safe mode pdario - the sfc again and the malware runs cos it sounds like something is gobbling up the machine with that core use.

I left chkdsk run this night; this morning I found Windows rebooted: I looked in the event log, but it seems no errors were found (bad sectors check skipped); anyway something happened, because I lost my Google cookies in Chrome (I found my self logged out of Gmail), I lost my ssh password in MobaXTerm and other oddities.
I tried sfc again and it stopped, I'll try in safe mode.

Anyway, I'm preparing for Windows reinstall, but I first need to be sure the HD is ok: can you suggest a way to check the disk surface?

Sorry for late reply mate one yest particularly of the actual surface you cab do with the Partition Wizard

Just install run and click on surface test see my pic it takes some time too.

This is a very useful tool to use for other jobs.

For testing the drive - I don't know what brand they are so I would suggest the Seatools one

SeaTools | Seagate go to the Downloads finder

Welcome to the forums pdario,

If it's unable to write files to the disk, then I would think of it either being some kind of malware, or possible disk failure/corruption.
