View Full Version : Random lockups

Right, I'm stumped.

A few weeks ago my daughter installed Sony's software for her mp3 player on my XP boot and I started to get random lockups. No BSODs or restarts, just system freezing.
This was happening all over the place for no apparent reason; it would happen while browsing, gaming or even idling with background downloading, defragging or virus scanning.
I unstalled the Sony app and dug out the parts it left behind and it seemed to be OK for a while then started locking up again.

I have a dual boot with Vista Ultimate x64 that is absolutely rock-solid. Not a jot of trouble with it.

I've gone straight into the BIOS hardware monitor after a freeze to make sure temps aren't high and they're normal for this system - ~55C per core etc. - so I've discounted that.

I ran memtest 86 v3.4 for the whole day I was at work and it came up clean.
After that I booted into Vista and stress tested the CPU with Prime95 for two hours without issue.

OK, I've been meaning to go over fully to Vista so I bought a new HDD on Sunday and set about installing clean with my original HDDs disconnected.
Would you believe that this installation started locking up after the first couple of reboots?

I racked my brain eariler to come up with whatever I've done differently with this Vista install compared with the stable dual-boot on my old IDE drive and the only thing I could come up sith was that I hadn't installed Perfectdisk on the stable install, so I uninstalled that.
Well it seemed to be fine but the machine locked up again in the middle of installing Office.

I'm currently in my XP boot and hoping it's gonna hold long enough to post this!

Any possible clues would be most graciously accepted; I'm at my wit's end with this.

Relevant system specs:
Athlon x64 X2 5200+
Asus M2N32-sli deluxe wifi
2x Samsung 512MB 667MHz
1x Kingston 1024MB 667MHz
Samsung 250GB SATA
Maxtor 250GB IDE
Maxtor 250GB SATA
Lite-On DVDRW SATA
Asus GE7300 gfx

Puzzler. Specially with the fresh install info. Before that I'd have guessed Sony ROOTKIT.

I assume that one of the two SATA drives is the new one and you're installing Vista with just the one drive hooked up?

What I'd do is...
-run the manufacturer's diags on the drive, verify it's integrity.
-change your RAM configuration...either pull the one gig stick and leave the two 512's or vice-versa.
-disconnect any printers/scanners.

Then try the install again.

If successful, you can reinstall the memory you took out.

If still good, add the other HDDs, one at a time.

It sounds to me like a hardware issue but you've already covered the obvious, so it's gonna be tedious from here on out.
Just on the off chance, have you another keyboard and mouse to try?

Based on the steps you have already taken, it could only be a handful of things, from a faulty SATA cable to a faulty controller on the mobo. Could also be something like a bad driver (an old PCI ethernet card from Netgear used to give me BSODs all the time with the default XP driver, had to find an alternate one). Hell, it could even be a problem with the CPU itself that it has developed with age - unlikely, but possible if you are able to narrow it down that far.

Just off the top of my head, and this is really grasping at air.

How old and what kind of power supply do you have?
A power supply going on it's way out can cause all kinds of gremlins in a system.

I remember not too long ago I had a bad one that was causing freezes like you are describing, just one day out of the blue for no reason. I was literately banging my head on the wall trying to figure it out... it was the PSU going out. Last thing I checked after stripping the system completely down.

After the fresh install, did the system hang up before you added the original HDDs back or after?

If it was after, it is possible that the system has performed an autorun when it detected the second sata drive. That in turn could have installed a virus or root kit onto your nice shiny new drive.

I've just cleaned a rootkit virus off a system, it was a real swine to find since it is able to hide from most virus scanners. It was the rustock.b trojan which seems to cause all sorts of different problems, depending on what software and service packs you's got installed. It is certainly out there, and seems to be one of the files being spread through the vulnerability in lsass.exe which microsoft fixed 2 weeks ago. Fixing the vulnerability just stops further infection, it doesn't cure any infection which has taken place.

The timescale certainly matches up with the problems you are getting. Have a look for rustbfix.exe, which will check and remove it if present.

I'll be off to Maxtor shortly to grab their software and see happens with that.

The lockups are happening both while I'm at the machine and away (though it's now been running since I posted last night) so I'd considered and dismissed the mouse/keyboard as potential causes. It does seem to happen more when I use the scroll or drag a window slider but that's probably just coincidence as I'm doing those a lot anyway. I have got some spare mice (with ropey LMBs) and keyboards so I'll be swapping as soon as it happens next.

I've tested the RAM (memtest) and it's controller (Prime95) but it's still worth considering and won't hurt to try.

Interesting idea on my AIO Epson. I'll unplug it after posting and see how long the system hangs on.

I have seen systems lock up when a hard drive is on the way out so it's certainly something to keep in mind.
I don't think the CPU is flakey though, since it handled Prime95 stress without errors.
The only drivers I've updated recently are gfx. The lockups are happening when there's nothing going on graphically so I think it's unlikely but I have just (after your mention of drivers) disabled the three un-needed nvidia processes just in case.

That sounds unlikely but they've all been EZ Cool (current is one of their high end modular units) so I can't rule it out. I'll consider it again later after the simpler steps.

Result was clean - I don't know whether to be happy or sad about that!


Well thanks to everyone for throwing your ideas into the hat, as it were. All suggestions have been noted and I will consider all of them as I go along.
I'm amazed that the system is still running after nearly 24 hours although not quite as amazed as I am with Spurs being 4-0 up against The Arse :)

Better go before I have to reboot and type all this again...

Well XP ran all that night and locked up while I was browsing yesterday morning. :(

Last night I changed keyboard & mouse and booted into the new vista install. While there I realised that MessengerLivePlus was something installed on both freezing installs but not the stable one so I disabled and rebooted to new vista... to have it freeze again after about an hour.

This afternoon I booted into the old, stable, vista installation and it's been working faultlessly since then.
At about 3:15 I started a Kaspersky rootkit scan and have surfed, chatted and played Freecell until I'm sick of it (there's nothing much installed on it at all) and it's still here, 8hrs 17min later.

I am now almost positive that this is a software issue. Surely this install wouldn't last this long with Kaspersky doing it's thing all the while if it was hardware?

I have had another brainwave: Office2007. It's something I hadn't installed on this Vista. If the scan completes then I'll be rebooting to remove that and see what happens.

BTW I love Vista but what they've done to Explorer is criminal; no toolbar buttons and full-row select hardwired into detail view? WTF are they thinking?

Have you looked in the Event Viewer to see if you can get a hint as to whats causing this?

The reason I haven't posted recently is that I moved house at the end of January and have had lots of stuff to sort out before getting back to the PC problem.

There's never anything in the event log to suggest a cause for the lockups, unfortunately & my 'brainwaves' have all led me up the garden path...

I was convinced it was software related since the problem never manifests itself in one Vista install but does in the other (same install source) and the XP install. I ruled that one out after an attempt to clean-install Vista again on the new SATA drive and it froze before it had even reached the desktop for the first time.
That made me think of the config and particularly that the problems happen on OSes installed on SATA drives while the stable Vista is on an IDE drive.
I thought I might be getting somewhere but Googling only threw up people with short lock-up problems so that petered out leading me to think I needed a new mobo. :s

Yesterday morning, however, I found the machine switched off after I'd left it booting into the stable Vista the night before. Subsequent power-ups allowed me use for at most an hour but more often it didn't get to the desktop before -plink- it powered off without warning.
This afternoon I swapped out the 650w modular EZCool PSU for a noisy generic 500w from babyputer upstairs and it's been fine since then.

Who knows, maybe it's that PSU after all, in which case it's the third EZCool PSU that I've had go tits-up under warranty - I paid the extra for an upgrade each time.

Bloody thing locked up about 5 minutes after that last post. :(

It's not instantly powering off now though so I gotta add a PSU to whatever I need to fix this thing.

Went to the local Computer Fair and got myself a KingWin 600w modular PSU this afternoon. Slightly cheaper (though more than I'd prefer to pay) than the Hiper model that was the only other option apart from a few hundred EZCool units that I steered well clear of.

As far as the lock-ups are concerned, I think I may have stumbled upon a possible solution.
Browsing possible motherboards for an upcoming job, I came across a customer review of another NF590 board where the guy said he had lockup problems until disabling the 'Cool n Quiet' feature so the last time my machine locked up I disabled it and it's been running for two days without freezing.
I'll be running another clean Vista install on the new SATA drive later to check further as that has been the most troublesome.

well it's been nearly a week of constant use in XP and another fresh Vista64 install without a single lock up so I'll consider it the final solution... enabling AMD's Cool N Quiet BIOS feature causes freezing on some systems.
Thanks for listening.
Someone can close this thread now.
