Windows 7: Random PC Freezes (Lock-UPs), HDD Light turns OFF.

Random PC Freezes (Lock-UPs), HDD Light turns OFF.

Hello Seven Forums.

First I'll start with spec of my rig:

Operating System
Windows 7 Ultimate 32-bit SP1
AMD Athlon 64 X2 4000+
Brisbane 65nm Technology
1,00GB Dual-Channel DDR2 @ 301MHz (5-6-6-18)
ASUSTeK Computer INC. M2N (CPU 1)
SyncMaster (1280x1024@75Hz)
1024MB NVIDIA GeForce 9500 GT (ASUStek Computer Inc)
232GB Western Digital WDC WD25 00AAJS-22RYA SCSI Disk Device (SATA)
Optical Drives
ASUS DRW-1814BL ATA Device
SoundMAX Integrated Digital HD Audio

From last week I'm encountering a issue with my PC, it randomly locks up for 30 seconds to 1 minute and the HDD light turns OFF and only the mouse is usable, sometimes it locks up completely and reboot is the last resort.

The first lock ups that I have encountered were issued on Event Log as "nvstor32 Reset was to \Device\RaidPort0" (Event 139) and I did the high performance power usage tweaks but it didn't work.
Even though it shows RAID error in Event Log, I use IDE since its one HDD.

The later solutions I tried were, upgrading/downgrading the nForce drivers (even tried the known Fernando's Tweaked nForce drivers which I'm currently using and they didn't fixed the problem completely, but just reduced the lockups.)

Next solutions were:

- HDD check (twice), one time with SeaGate DOS and later with WD's tool and both test were Long Run and they successfully passed without error. (That got me wondering actually )
-RAM check with MemTest86+ and that passed successfully too...
-Re-Installed Windows 7 TWICE.
-Downgraded the BIOS from Beta Version to Last Stable one with EZ Flash 2
-Cleaned the rig from dust.
-Even changed the SATA cable from MB to HDD and SATA Power cable.
-Completly Unplugged the DVD Drive from MB.

None of them helped

But I have to mention, after the first re-install of the Windows and after some usage it asked for CHKDSK and after it ran, it discovered some errors, fixed some files and then I couldn't boot the Windows after that.
I enabled the option not to reboot PC after crash and it showed a BSOD which I forgot the Error Name/Code.

After that decided to re-install again, after some usage again, ran CHKDSK, errors were found but this time it successfully booted after restart.

Also, even if it still happens, the Event Viewer does not show the Event 129 error mentioned like it used to.

I'm totally confused, I thought it was the HDD or the RAM but the HDD Test PASSED and same for RAM.

A help with this would be very grateful :)

Hey, we had another friend here the other day with the same problem - nvstor64 in his case, but he decided to format before all tried.

If this was my PC I would try these as well:

- (If you can) make an image of the OS with Macrium free. Something to roll back to in case all else fails. Imaging with free Macrium
- Create a System repair disk and make sure your OS is seen by booting with it. (search for system repair in Start menu and it will show)
- Create a system restore point.
- Run regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services
find pciide and change Start to 0. Find nvstor32 and change value to 3. (This will disable nvstor32 and enable normal ide drivers, might stop you from booting. System restore with repair disk if so.)
- If you can boot, download and run AS SSD benchmark program. It will tell you in upper left which driver is currently used to verify pciide is indeed loaded.
- If all is good, use PC in this state for a while to see if you are satisfied.

- If the above fails, try uninstalling the chipset drivers all-together and see if you will get these lock-ups. Decide on a treatment according to the outcome.

- You may try to do a clean boot and see if lock-ups go away. Troubleshoot Application Conflicts by Performing a Clean Startup

Just few ideas, maybe others will chime in too.

Thanks GokAy, but before seeing your reply I tried to switch the HDD and used another one, I re-installed new Windows on it, and it turned out, it was the old HDD acting up and dying, probably I should reconnect again later time just to transfer the important files that I keep there. Even I feel a bit of significant performance improvement with this drive even though is not brand new.

I'll guess this is solved, thanks again .
