Windows 7: Random restarts in Windows 7

I'd shift focus to the configuration of the dual display after making sure you have the latest display driver. You may also need the GPU's full software package to get full functionality of the dual display. I'd try with and without the full package, too.

Just a bit of an update on this,

It seemed to be working with the single display for a while. I've had 3 days out of it in the past without the random restarts (that is with the PC in sleep mode for a lot of that time) so I wasn't going to count my chickens.

I had a couple of BSOD's 1 of them while I was installing the latest display driver - interesting that windows update directed me to the 32 bit version. 1 was an ntoskrnl.exe I'm assuming that one is down to a driver somewhere - I tried doing a chkdsk /r anyway and that didn't appear to alter anything.

Aside from that encore was working fairly stably with Chrome & Outlook open so I decided to go back into the BIOS and reset the settings back to default - I didn't want my RAM frying with the upped voltage.

Mistake. Random restart city (sorry!)

So more playing about with the BIOS settings, changing one at a time to see what happens (the manual isn't very helpful at all

"ASROCK VDroop Control - Use this to enable or disable ASRock VDroop control. Configuration options [With VDroop] and [Withoug VDroop]. The default value is [With VDroop]."

Yeah, thanks for that.

I wasn't having much joy until I ramped the DRAM voltage up again a couple of steps. I'm not convinced it's right yet but I'll see how it gets on.

Obviously I'd like to have the two monitors running but I'll leave that for a while until I'm happy that the restarts have stopped.

It's one of the reasons you should always get your driver updates yourself. Never rely on Windows Update or Device Manager to update your drivers until you've exhausted your PC Mfr., Motherboard Mfr. or the software/hardware Mfr. resources.
Although that's the first time I've heard of it giving you 32bit when there's most likely 64bit available. That's probably why you blue screened there.

Also when updating graphics drivers you should ideally:
  • Download and install Driver Sweeper.
  • Boot to Safe Mode
  • Uninstall your current Graphics Driver set up using Driver Sweeper.
  • Reboot to Normal Mode.
  • Install your new Graphics Driver set up.


HTH.

This is not XP. There is no reason to advise average users to go on a complicated driver hunt.

MS spent a fortune getting the drivers into the installer or quickly updated via Optional Updates, even paying manufacturers to build them under WHQL so that they wouldn't hold out to force us to buy newer hardware as they did in Vista.

We have cases here all the time where users unknowingly change out the drivers given by installer and have performance problems that require reinstall. I would not change out any drivers given by installer and optional Updates unless performance problems point to that driver.

Sure there will be occasional mistakes with drivers from Updates, but nothing compared to trying to do them yourself using old generation tools. It's like trying to use a wrench on a Lexus' computer.

Old generation tools never mentioned by me!

We get no reports that I've seen in Win7 that driver remnants cause conflicts when installing new drivers, as they could in XP.

This along with full automation of drivers in Win7 makes tools we once depended upon like Driver Sweeper and DriverMax obsolete.

If I sound emphatic it's because I just reinstalled my nephew's Win7 via TeamViewer after he used DriverMax to update his drivers.

I'll bow to your superior knowledge. Although I'd never have trusted DriverMax with anything.

I thought I had it again! Still getting random restarts. I think I'm forgetting they're random so get a bit excited when the machine stays up for a while!

It went down last night while I was encoding a video file. I'd been playing about with 3D Mark 03, 05 and 06 before that and also ran OCCT (not for long admittedly) none gave problems.

I booted into windows xp (32 bit) on a separate drive and encoded several files with no problem whatsoever. I haven't used XP much on this machine but on my previous computer XP never crashed. Well, ok it locked up when using Firefox after updating to 3.6 or something like that but that could always be recovered just by closing it in task manager.

Today I have unplugged everything from the machine aside from 1 monitor, mouse, keyboard and speakers and removed everything from startup aside from dropbox, Norton and Spybot (I didn't have Spybot or Norton runnning at startup when the problems started happening.

I thought I had it when I managed to encode one video file so I reset the BIOS to defaults again, having saved the old settings. Came back in and tried encoding another video file and had a random restart. Put the saved BIOS settings back in. Tried encoding again & had another restart.

I think I'll try another full reinstall again and make sure I wipe the drive this time.

Suggest you replace Norton with Microsoft Security Essentials and Spybot with Malwarebytes. This can solve performance problems such as yours.

I don't have performance problems!

Norton is no longer the resource hog it used to be. Microsoft Security Essentials is a far inferior product than norton. I do have Malwarebytes instaled. Malwarebytes often spots things spybot doesn't and visa-versa.

Norton wasn't running on my computer when the problems first occurred. Spybot was installed but wasn't running in the background.

I did a full reinstall of Windows 7. That didn't help at all. Even with just the minimum devices attached to the machine.

My last attempt at fixing was to push up the DRAM voltage even higher than I'd risked before. I also discovered the windows power saving feature and changed that from balanced to high performance. I thought that 'feature' was only present on laptops!

Since then I haven't had any crashes and I am once again running with two monitors. I don't necessarily think it has anything to do with the windows power saving options but hey, it's working for now - I don't want to tinker with anything else!
