K7t Turbo2 Athlon2200 Random Shutdowns

Just got this new setup. I have K7T Turbo2 Athlon 2200+ and 256Mb pc133 ram. Every now and then the pc will just automatically just shutdown and reboot itshelf. Just comes to a complete halt. Its usually when their is alot of cpu usage. But sometimes their isnt any cpu usage. Most of the times it does it is high cpu usage. I dont have any device conflicts in windows or anything like that. Im using a Rexus 400watt powersupply with p4 connector.
EDIT: And the temps are fine. 37-47 C

K7T Turbo2 V5.0 Cannot Properly Shutdown

Hello everyone,
The thing is that "Power" button on my case doesn't work for me properly. When I'm just booting the machine, the moment I press the power button the whole system freezes (the hdd led remains on, power led goes off, fan is on, disks are on, monitor is on, boot screen is on). When I press it again, system reboots.
Many of you had the similar problem before... I tried most of the suggestions... Nothing worked for me.
When in WinXP, the moment I press "power" button, system performs the shutdown, but after the drives arу off, monitor is off etc, cpu fan remains on.
Many of you will say that my PSU is not good enough. The same PSU works wine with the same config, same cpu with Abit K7T 1.3 though.
Actually, I've been able to shut down properly once. I had my machine turned of (with the I/O switch on a PSU) for quite a while, and I cleared out the bios settings. But after the machine remains on for more that a few minutes, "power" stops working.
Please help.
Configuration:
K7T Turbo2 V5.0
1Gb PC133 RAM
AMD 1700+ Athlon XP CPU
Realtek 10/100 PCI LAN
Gforce2 GTS-V
Athlon XP certified 300W PSU
Windows XP Pro, SP1

Where did you get the CPU from and do you know for sure it was pulled from a working system? eBay, and no... :(
Are you 100% sure you have Turbo2 & the OPN on the CPU itself is AXDA2600DKV3C? Yes, I visually see them with my own eyes.
You did clean base of HSF and use fresh thermal compund/grease when installing CPU & HSF/cooler? Yes.
I assume it still works with the 1800+? Yes, using it right now.
Recheck power connections and make sure the plugs are fully seated (ATX 20 pin, JPW1 square 4 pin) I'll check that the next time, probably tomorrow.
Is PSU +12V more than 10-12 amps? No idea what you're talking about here...

K7t Turbo2 Shutdown Temperature Issue

Hello All, noob question:
I use my computer mostly for playing games. I play Warcraft III, Dungeon Siege, and JediKnight2 mostly and while I am playing sometime or another my computer will reboot in the middle of the game.
From reading the manual under the PCHealth section I assume this has to do with the Shutdown Temperature setting reaching a certain point and rebooting my computer to save it from frying my components. I have a standard case with two fans in it, thermal grease between the cpu and the heatsync but other than that I have limited knowledge of anything else that may contribute to this problem.
The first thing I tried was replacing the video card which stopped Warcraft III from rebooting but caused both Dungeon Siege and JediKnight2 to now reboot. I changed the resolution in Warcraft III to a higher resolution and now it reboots too. This confirms to me that it is a heat issue. What should I buy or do to alleviate my problem? Thank you so much for all your help in advance.
My components are:
AMD Athlon 1800XP
MSI K7T Turbo2 Motherboard
512MB PC133 Ram
Volcano 5 Heatsync
Nvidia Geforce2 MX 400 64MB & Riva TNT2 Turbo 32MB
Seagate 20GB 7200 RPM hard drive
Texas Instruments IEEE 1394 Controller Card
Lite-on 32x10x40 CDRW
Memorex 48x CD-ROM
2 fans
Viewsonic 19" E790 Display
and a partridge in a pear tree

Hi!
Well, it can be a heat problem, it could be a problem with your PSU also ...
About heat: from the list of components, I do not see a clear reason why there should be a heat problem - it all looks pretty normal to me :] Do you have any idea about the temperatures in your system? Temps can be readin BIOS, but more convenient with the program MBM 5 which can be downloaded at http://www.livewiredev.com.
I think (not sure, though) that temperatures of the video card can be read with a program called rivatuner - it can be downloaded here.
About the PSU: can you tell a little about brand & specs?

K7T Turbo2 shutdown

I have a K7T Turbo2 motherboard with a duron 1.3 GHz processor bought as part of an upgrade package about a month ago. Lately, the machine has been shutting down after a period of time. The video shows a black screen with a white square in the middle. Input activity will not wake it, I have to reboot. Norton antivirus is installed and there a no driver issues.
any advise? Thanks.

Hi Patty,
This Thread belongs in the VIA Forum since the K7T has the VIA Chipset, I will move it over there. 8)

K7t turbo2/amd XP 1800! ack! help!

i recently bought a k7t turbo2 (ms-6330) to go with my amd xp 1800, im running 2x 512 and 1x 256 ram under winblows ME. and ever since day 1, i have random lockups when i try to move or copy files in windows, but if i use dos-prompt i can transfer files just fine... also when i try to shutdown or reboot i get error from windows. i have tried underclocking the cpu, swapping out the ram... i have installed all the most current drivers for everything and i am clueless what else to try... i got a 300w amd certified psu, 20gig maxtor along with a 20gig seagate for drives. i have disabled the onboard sound as well as the printer/serial ports... i run bare bones windows setup with no junk in the backround... have 3 case fans and amd certified cpu fan so i have eliminated temp problems, it happens whether the machine is warm or cold... i even tried upgrading the bios to 3.5 to no prevail... i have no issues running any of my games from halflife to quake to diablo to everquest... other than these 2 isuues, my systems just blazes with no issues...
any ideas?

Yank out some of that ram, like the 512k stick and then try it out . ME doesn't need all that to function. BIGDADDY51CT.USA

K7T Turbo2 & heatsink clip

Came across an interesting problem/solution while rebuilding a system for a client, FWIW. They had been experiencing random errors with increasing frequency for several months, including Windows registry errors on boot, I/O errors, garbage error messages onscreen, temporary screen freezes and lockups, and then the system finally died completely. I ran through the usual troubleshooting steps and found the motherboard and CPU were bad (I'm guessing power surge but who knows).
Installed a new K7T Turbo2, new Duron 1.3 and new (quality) power supply. I reused the old heatsink/fan from the dead Duron 900, cleaned and applied thermal paste as usual. System would boot fine, then freeze, or show various hardware errors during POST. After shutdown and a long period of cooling off it would boot as normal, then freeze and go into POST errors again. I knew I had installed everything properly, but I took another very close look at the heatsink and found that it was somehow tilted ever so slightly in relation to the CPU, even though it otherwise appeared to be installed correctly. This tilt was so slight, there couldn't have been more than a few millimeters of dice that weren't in contact with the heatsink. In looking even closer, I discovered that the heatsink clip had a bend on one end which was closer to one end of the clip /~___~~\ than the bend on the other end. After reversing the clip, the heatsink then seated properly and the system is running fine with no errors.
I'd never run across a heatsink clip that had only one proper orientation, nor did I realize how critical it is for the heatsink to absolutely, positively have total and complete contact with every last bit of the dice in order for the system to boot! Sorry for the length of this post, justed wanted to throw this in, in support of the troubleshooting guide in this forum, and also to vent my frustration at having spent several hours trying to figure this one out.

on good coolers the bar is not removable
another clue on one were it will fall out is there is normally only one end has the clip for the screw driver and this should go towards the top of the cpu socket, and be on same side as step in the coolers base

K7T Turbo2 (MS-6330) Booting problems

Last night, I installed an Athlon XP 1700+ on my K7T Turbo2 mobo. I can not boot into Windows now. Windows XP will hang on loading up mup.sys, and 98 resets at an indeterminate time. I cannot install Windows 98 or XP either, as both hang on the setup (Before I can even access recovery mode for XP). I've swapped out all my PCI devices, disabled nearly everything in the BIOS, etc... nothing good. Heres what I've got.
Athlon XP 1700+
K7T Turbo2 Mobo
ATI Radeon 9000 128mb
ATI Radeon 7200 32mb (Secondary Display)

Any help would be greatly appreciated! Do I need to set my FSB to 133 so I can use the 1700? I have updated my BIOS to the latest version. How would I increase the FSB?

Welcome
Shutdown and remove jumper J17 (see manual - jumper near ram slots). If no boot, clear CMOS and try again. Be sure to use Fail Safe Defaults for install.
You've got a really heavy load, and hope your PSU is up to it. Do you have at least 200-220 combined watts on +3 and +5 circuits of PSU (see PSU label or maker's site).

K7T Turbo2 and Athlon XP 2400+

Hello everyone !
I have a question about K7T Turbo2 motherboard and BIOS update.
Here it goes: I reacently bought Athlon XP 2400+ and installed it on my mobo.
But after reboot my PCU wasn't recognised and I read on MSI website that I had to
upgrade my BIOS from 3.5 to 3.6 ( I think, don't remmeber the version ) . So I did that too
and this time bios showed my CPU as XP 1800+. I said there is something wrong with CPU or
they gave me a wrong one, but NO. After reading the manual I realised that that XP 2400 uses
266 insted of 100 ( standard that came with mobo )and that I had to remove J17 jumper to make it
work and also had to change options in BIOS --> like FBS 133 and multiplier 15 to get XP2400.
Reason that I'm expling what I did is to let you know what stuff I did before I came to this forum to
ask a Q. Anyway after all of that fuss PC works and shutdowns OK. But ( yeah there is a but ) now insted
of starting at once I need to press power button one time -> and you can here power starting and lights
showing but system not starting. Then I push and hold button for a few sec to shut it down. After
second push of power button system starts as normal. It looks like it need a bit of warm up ( like my car in winter time ) before it actuali start. Is this a BIOS error becouse it can't start the system with ONE
push of the button? Never had tha problem with Duron CPU and old BIOS. Need some help ..
Thanks

Hi!
I think I solved your problem! It seems that I had exactly the same problem and the same settings you have. Then, I read this Trouble Shooting Guide at:
https://forum-en.msi.com/index.php?threadid=1131&sid=
which says:
"As for mulipliers with AMD CPU's, just set them Automatic, as they are hardcoded on the CPU themselves and will allway's be correctly, even if if you think the BIOS doesn't know it."
So I changed the multiplier from BIOS from 15 to Default, and now it starts up great even at the first time! Even my CPU benchmark score with PCMark2002 free went up from 5195 to 6344 so now it actually works much better than with the multiplier 15!!
Try this before buying a new PSU and tell if it helps...
Regards,

K7T Turbo2 keeps switching DMA to PIO

OK, I have a K7T Turbo2, and its pretty stable but I have a big problem. Every couple of days (Actually it happened 3 times today for some reason), it switches my Secondary IDE channel from DMA to PIO Mode 4. When I try to install games under PIO mode, the installer freezes randomly and my system becomes unstable. Also when I try to burn CDRs and DVDRs, my system gets slow and unstable under PIO mode, but it works perfectly under DMA mode. I have to uninstall the secondary ide channel and reboot to get it to switch to DMA, and its a major pain in the butt. Please can someone help me with this, its starting to drive me crazy.

K7t turbo2 + geforce2 ultra

when i have my geforce2 ultra card in the k7t turbo2 motherboard i get weird charactors displayed. like on the bios screen, charactors will be grayed out or missing.
i also noticed this problem before with a different geforce2 ultra and a k7t pro2. is there a fix out or a way to fix this problem?
also, windows 2000 advanced server hangs on startup when i install drivers for the video card

my geforce4 ti 4600 works fine in the computer, as does my geforce3 ti 200.
this geforce2 ultra works fine in my other computer.
i took all nics out, there were no pci cards installed, and still get weird charactors on random spots of the screen
after leaving the computer unplugged with cmos cleared for a couple hours, now during 2k adv server setup i no longer have the acpi error. I can get the machine to install 2k advanced server now and windows runs perfectly until i install the drivers, windows will not make it to login after installing drivers and rebooting. ive tried many different versions of drivers

Macbook problems, hard drive crash, random shutdown, freezes

I bought my macbook used a few months ago, and it worked flawlessly until about 3 weeks ago. The system started freezing and not booting (getting folder icon instead of apple at startup). I ran drive setup and tried to repair the drive, but this did not fix the problem. DiskWarrior also could not fix it. I pulled the drive and installed a new hard drive, as I wanted a larger capacity anyways. All my problems appeared fixed for about two weeks, then similar problems began occurring. I backed up all the files I needed to an external firewire drive and attempted to reformat the new internal drive. Drive Setup says it can not reformat the drive - can't mount it and if it does, the drive disappears while in the process of formatting. I pulled the new drive and am having it replaced under warranty. I am using the firewire drive to run my computer, and this seemed to work fine for a day or two until the computer just started shutting down with no warning. Everything goes black, including the little light on the front of the computer. I have to hold down the power button for 10 seconds before it lets me start the computer back up. I had read this may be a memory issue, so I ran memtest and it says the memory is fine (I need to do it in single user mode still, however). I also tried pulling both sticks of ram. They are both 1GB crucial memory. I put each stick in by itself and tried it in both slots and was able to reproduce the shutdown issue with any ram configuration of either stick.
After all this, I realized the firewire drive was only running 10.5, so I updated all the software through software update, and it is now running 10.5.2. It seems to be working better as I have not experienced a random shutdown yet, but I'm anticipating it may start back up soon. Today, however I experienced a different problem - the screen froze on me and the only way to get anything to happen was to force a shutdown with them power button. It's restarted and seems to be working fine again for now.
I've run some logs and here's some things I've found:
When the latest freeze happened, I got this repeated over 100 times:
Apr 29 11:04:31 jon-turners-macbook quicklookd[536]: CGContextClosePath: no current point.
I've also seen this:
Apr 29 11:18:19 jon-turners-macbook kernel[0]: Previous Shutdown Cause: 3
Apr 29 11:18:19 jon-turners-macbook kernel[0]: GFX0: family specific matching fails
Apr 25 19:19:50 localhost kernel[0]: hi mem tramps at 0xffe00000
Should there be anything else I can check? I would run Apple Hardware Utilities, but I don't have the original disks, just the Leopard installer. I have Disk Warrior, but it seems strange this would happen with multiple systems and drives. I'd like to get Techtool Pro, but haven't had the money/time to order it yet.

Thanks for the replies!
Yeah, I think it's the HDD. I was just worried that the RAM was bad and corrupted the HDD or something, but given the symptoms I think you guys are right. Ordered a 7200RPM 320GB HDD off Amazon Prime...will be here tomorrow
I'll post how it goes after I finish installing it. I'm backing up as I type.
I wonder if I can fix the ir port and the sleep indicator light when I install the hard-drive. The sleep indicator light never turns off. It stays on as long as my computer is on, only turns off when I shut it down.

K9N Platinum: CPU upgrade = Random shutdowns..

I just installed a new AMD Athlon 64 X2 3800+ EE in my MSI K9N Platinum motherboard (MS-7250 v1.0, the 070 model according to the box). I had updated the BIOS to version 1.7 before installing the CPU. Anyhow, I got the CPU installed and it seemed to be running fine. Until I started playing my games. Upon playing fifteen (!!!) minutes of Day of Defeat, the system completely turned off. COMPLETELY. No error messages. I check core temp's log to make sure the CPU wasnt overheating; it wasnt. The max temp was 38C on one of the cores. Just to make sure the CPU wasnt the problem, I ran two instances of prime95 for 5 hours and there were no calculation errors whatsoever. I also ran 3-4 loops of SuperPi, using the 32M test. No errors.
I have come to the conclusion that it must be the motherboard, and possibly it does not like the CPU. Or else it is having the same random shutdown problems as many other K9N Platinum/Ultra boards are experiencing. From what i have read, this issue only relates to boards that are 040, 050, or 060 models. I have a 070 model, and I AM GETTING THIS PROBLEM!!
Help!!!

Any ideas?

well, i know that ACPI has to do with power saving features.
http://en.wikipedia.org/wiki/ACPI
and HPET also has something to do with CPUs
http://en.wikipedia.org/wiki/HPET
and MCP55 is the nortbridge.
so i suppose i can conclude that it protects from overvoltage or promotes more power-saving? i dunno i really dont care as long as my PC works now,

White Macbook 2006 random shutdown solved removed cpu heatsink and more

I picked up a cheap macbook from a secondhand retailer for $300 and it regularly shutdown, froze, restarted as well as the grey kernel panic screen completely random no real pattern. I set about trying to solve the problem swapping ram and hard drive with my identical 2006 macbook (which I had similar problems with last year, fixed that one with a new battery connector cable). The ram and hard drive made no difference so I downloaded istat menus to see if any combination of cpu voltage, current and temperature were causing the random shutdowns. It seemed when the temperature reached certain values the computer would shutdown or freeze(around 30 to 50 degrees). I'd read on other forums about faulty cpu temperature diodes so I reapplied heatsink compound to the cpu heatsink and checked all the wiring for shorts but nothing seemed to solve the problem. I was ready to retire the computer and use it for spares for my other macbook when needed but I pulled the keyboard off one more time and tried something completely radical. This fix requires some forward planning and software installation but it has completely solved my Random shutdowns completely.
for instructions see my next post *Fix for random shutdowns white macbook*

Ok this is not for the non technical person but it is quite a simple process with the right instructions.
This first step is very important install the software coolbook($10) and fan control (Free)( not smc fan control). Set up coolbook to operate the cpu at the lowest speed and voltage for both power adapter and battery(1002MHz and .95Volts). Remove the keyboard to access the computer logic board (instructions can be found at iFixit). Remove the four screws and two connectors holding the heatsink to the logicboard and gently lift the heatsink out (very important that you leave the fan screwed in and connected). Close the computer back up if you wish to test just gently connect the keyboard and loosly sit the keyboard back in. Restart and reset the pram immediately. Let the computer boot up and then open system preferences and configure Fan Control to your liking. So far no random shutdowns for over a week (was getting many a day previously.

Macbook won't detect external display anymore - Random shutdown injury??

Hi,
my Macbook has the dreaded random shutdown thing happening, often it can't even get through the startup sequence. If I reset the PMU and PRAM and check the disk every week I can keep it running. Applecare are making not particularly helpful suggestions like "run it in safe mode" - hello people, random means it can take days to happen again... I use this computer for work so I need it at full capacity every day!!!
Anyway, enough angry ranting. The casualty of today's RS and subsequent PRAM PMU resetting is my external display (Viewsonic LCD). The macbook is no longer sending signals to it (display says "no signal"). When I ask the macbook to "detect displays" nothing happens. I have restarted the macbook several times and unplugged and replugged the display connection it doesn't help. Yes, I have the AC power cable plugged in on the Macbook (I know it doesn't like talking to the screen if I don't).
The display and macbook have always worked fine together in the past...
Does anyone have any suggestions on how to test for causes or fix this display related problem?

You don't mention ever having brought the problem to Apple's attention, or what resulted from your request for Apple's help with it. This isn't a universal or widespread problem. It may be a hardware fault in your own equipment that needs to be resolved with a repair, or it may be a software problem (corrupt file, incompatible software conflict, update needed, etc., etc.). You seem to think Apple should have fixed it for you without your lifting a finger, and you're eager to complain about Apple's lack of support. But you've offered nothing to indicate that Apple even knows you need support. You do have to ask for it. Have you done so?
We have no idea what steps you've taken to try to narrow down the possibilities, e.g., making sure the monitor is turned on; trying a different video cable as iVmichael has suggested; testing the monitor with the same cable on a different computer; testing a different monitor with the same cable and then with a diferent cable on your computer; substituting a different cable adapter, if you are using one; applying all applicable system software updates and then Repairing Permissions and Repairing Disk; starting in Safe Mode and seeing whether the monitor is recognized and activated then; seeing whether the monitor is detected in System Profiler; and so on. You may have done some of these things, but you haven't told us about them or about the results.

To Everyone with Random Shutdowns! (Solved! REALLY!)

Hey all,
I had posted about a week back about my Macbook (Core duo white, late 2006), it was having the same symptoms as some of the others with the known random shutdown syndrome (RSS). Like many others I had thought it was the end of my macbook and the logicboard needed replacing because that is what the 'genius' people do, but I was still wondering what would cause it. It would randomly shut off! (or so I thought) I'd be typing in Safari, watching a youtube video, and even playing games, it would just shut off and I could hear the hard drive spin down. I'd restart and it would do it again sometimes right away, sometimes hours later.
This got me to thinking (like others have said) that it must be an issue with over heating. To test my theory I backed up my HD, and tried to reinstall Snow Leopard after zeroing the HD (as a fresh install). During the install process the Macbook's fan started to get loud and then it happened, it died again! So, this proved to me that it is NOT a software/OS issue at all, which means the said efforts in other posts of changing screen saver and energy saver settings had nothing to do with the cause! Aha moment!
I thought to myself... something is making it shutdown, obviously, and has to do with too much heat as the fan was going crazy even while reinstalling the OS. After reading many posts on different support forums I came accross the possibility that it could be the heatsink and/or sensor that is attached to it. I also found out that this "RSS" only applies to the non-unibody, core duo, and core 2 duo macbooks... you know what that means?
These models are the only ones with the shared memory and GPU on the same heatsink! GAH! A possible solution presents itself? To make a long post even longer... I removed the keyboard, carefully unscrewed the heatsink and fan and what did I see? Cracked and dried out thermal paste on the CPU AND GPU, they are both under the same heatsink after all, this was bad, really bad.
Luckily I had some Arctic Silver thermal paste in a tube from years ago when I upgraded my PowerMac CPU. Using some rubbing alcohol and a soft cloth I removed the crud on the heatsink, processor, and GPU (I might add that there was way too much paste on there in the first place). I waited an extra few minutes to make sure the alcohol evaporated, and then I applied a small (dime sized) amount of thermal past directly onto the two chips, I aligned the heatsink carefully and gave it a very small gentle push down onto the chips, reattached the sensor wire to the mainboard, and screwed the heatsink back in.
After putting the keyboard back on and making sure all screws were in... I immediately turned on the laptop and reinstalled the OS. The OS install took approximately 10 mintues! (crazy!) The last time I did that it took over 30 mins to install! I was stunned!
After the OS installed I let the computer idle and shut down, I let it sit for about an hour to allow the paste to contract as it cooled. After starting up again I immediately downloaded Temperature Monitor and installed it (I did have it running when my mac had RSS by the way), here are the results to prove my theory:
My Macbook with RSS:
CPU1 and CPU2 Idle temp - 114 degrees (F)
Heatsink temp - 128 degrees (F)
Approximate over heating temp - 184 degrees (F) (causing the heatsink sensor to shutdown the laptop)
My Macbook with new high quality thermal paste:
Idle temp of CPU1, CPU2, and GPU - 77 degrees (F)
Heatsink temp - 84 degrees (F)
Running temp with adobe CS4, youtube, and typing this message - 103 degrees (F)
Pretty amazing if you ask me!
Before I applied the thermal paste my Macbook took at least a minute to start up with a fresh OS install, now it only takes about 15 seconds! I have not heard the fan spin up and go crazy since! And I can't even explain to you how much fast it is now!
This does prove that Random shutdown syndrome (RSS) is caused ONLY by your GPU over heating due to old thermal paste between the chips and heatsink! A design flaw by Apple? probably not because thermal paste will crack and dry over time.
This also proves that energy conversion to data in the chips can decrease because of over heating, causing the computer performance to dramatically drop!
So before you take your out-of-warranty macbook to Apple or a repair shop, see what your internal temp readings are and try to replicate the problem with over heating your CPU/GPU! This was a 10 minute fix! I am still amazed at how much faster everything is, and haven't had a random shutdown since! I hope this helps alot of people that think they are out of luck and have to pay to get it fixed!

I too have this problem as well and it has been getting worse lately, I don't know what to do anymore. Here is a little info about my macbookPro. I have the late 2008 unibody model, i bought it in late 2009 Refurbished from Apple. Recently my mac has been turning off out of nowhere. I may be doing something and all of a sudden it just shuts off, it usually happens faster when i start to open up more programs like Photoshop or Final Cut Pro. My mac is out of warranty now and i dont know how much apple is going to charge me to fix it. i mean they want 50 bucks just to talk to them on the phone (ridiculous if you ask me)!.
