K7T266 PRO2 RU constant freezing! need help!

Ok, after two weeks reading every thread in this forum that has this word "K7T266" on it, i decided to write these lines:
My good k7t266 pro2 ru stopped working a few weeks ago, i thought it was the cpu processor (athlon 1800+, i think thorougbred), the thing is that windows xp gots freeze randomly, i have reinstalled almost 10 times, trying everytime different bios combinations (version 3.3 through 3.7) and different settings (the ones written in some tweak/perfomance threads here), i have also tried three different power supplys (250W,350W and 400W) (amps always exceeded your recomendations on other threads), i also have tried different memorys in different combinations (1 bank, 2 banks, etc), tried too 2 different video cards (gforce 4200ti 128mb from evga and a gf4 440mx from excalibur i think), i have removed every other card (nic, usb connectors, etc), also have tried with a different hard disk (40 gb and 60 gb from maxtor and western digital). Tried cleaning and adding new thermal paste to the HSF (is the one that comes with the cpu), tried connectin the cpu fan to the power supply, tried with a different cpu (athlon 1300, palomino i think). I dont remember what else i tested, oh, i have it totally "naked" (no case) , i can send you pictures of it , oh, another thing i tried different via drivers (none, 4.43 and 4.49) , and windows xp has sp1. Ok, i dont remember anything else by now, i am buying a kt6 delta (i saw bas loved it) it must arrive this tuesday but i dont want to throw the k7t266 to the trash, it seems to me that there is some bad capacitor (they dont look abnormal, i have fixed msi boards with blown and inflated capacitors before). Ok , i just wanted to know that i really need your help here, dont know what else to say. Thanks a lot for your answers. :(

Ok, i am not at home to test the voltage thing that h2O proposed (i tried once but was afraid of burning cpu and memory, these things arent cheap in venezuela), and about the temps, they were around 40 (idle) and 50 (playing battlefield1942) (it's very hot in my room), that's why i got the board undressed (no case at all, just PS) . H2O , can you please help me with the voltage thing ? which values are safe and can be tested? tomorrow i will have the kt6 delta but i still want to know if the k7t266 can be used or sold.
Other things
- i have cleared cmos everytime i changed settings proposed here.
- i have clean installed xp (format c: partition) , BTW it sometimes got freeze during the first stages at installation , specially if i set FSB to 133.
- i did not tried to overclock (too hot and too expensive to try, i can not afford and/or find a better cooling device (water, best fan, etc)).
Again, i would really appreciate any help you can give to this poor bastard ;(
PS: sorry for my english, it's not my native language.

IPad mail app freezing, need help

I've experienced my Mail app freezing twice in last two weeks in the middle of writing a mesage. I can't save it as a draft nor can send it, can't move to another folder. But if I leave the Mail app and go to gmail app it works. Anyone knows what's happening?
Thank you in forward for your help!

Have you tried the simple basic things?
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Quit the mail app and restart.Go to the home screen first by tapping the home button.Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
It is possible that you have an email in your inbox or trash folder that is causing the problem as well. Maybe an email with large attachment? If you have an email like that - try deleting it from the iPad. You may need to do that from the server in your webmail using a web browser if the mail app keeps frezzing on you.

Constant freezing. HELP

Hi, I am living in Egypt this year, and thus do not have access to a mac store, so this is where I turn to. Recently, my macbook has been acting up. It has been freezing up to 3 or 4 times a day. Usually this happens when I have a few programs running at once. By a few I mean like 3. iTunes seems to be a real problem too. It seems like every other time that I open up iTunes and play music/tv shows, it freezes and then I have to shut it down using the power button. Mind you, this computer is relatively old, it will be turning 4 this November so maybe its just a sign of it nearing the end of its life. Either way, its a pain.
Help would be very much appreciated,
P

It sounds like the memory is failing - if you are comfortable doing so, try reseating the memory. You might want to also try resetting the PRAM http://support.apple.com/kb/ht1379 and a disk permission repair.
If these suggestions don't work, try running the Apple Hardware Test (AHT) http://support.apple.com/kb/HT1509 to help determine the problem. Keep in mind that it takes a while to complete the AHT.

Macbook pro keeps freezing need help!

i have a macbook pro 15 inch and i can't keep it on for more than 15 minutes before the screen dims down the whole screen or it freezes and tells me to hold down the power button to reboot the computer. Sometimes i reboot right away and before the OS loads it does it again? what is causing this and how do i fix it? I got my macbook less than a month ago....

Ok i tired all that and still did not help
i ran the fsck -fy thing and it seems like it kept getting a kernel panic during that which seems weird. The scrolling text didn't really give me any real information from what i could see but i know it didn't help either.
I have let the computer sit all night and i have now spent about 5 mins without a KP so im thinkin my RAM may be heating up and jarring loose or something if that is even possible
Thanks for the info so far guys!
EDIT: ok i have ran the fsck -fy thing in the scrolling text again after start up with APPLE/S command. It went thru its checks and said "Macintosh HD appears to be OK"
So i infact was getting a panic last night during that scrolling text boot up. Again i think it may be a heat problem. During that panic tho all this weird code came up but it said (panic) and hard jumbled words but i sort of remember a line saying something about opitmized pointer or such.
Thanks again guys for the helpt tips!

Email app freezing-need help

This morning I turned on my iPhone and went into my email. After everything came up, I began deleting the non-essential email and half way down the list, the phone freezes or gets stuck and the only option I have at that point is to either press the home button for several seconds or do the restart.
This has happened three times so far but it hasn't happened before today.
Anyone have any ideas why this is happening and anyone know what else I can do other than restarting?
Thanks.
iPhoNettie

I just had this happen today as well, although I have also had it happen previous to today.
When my iPhone freezes during deletion and after 30 seconds or so and it does not come out of it, I merely turn the iPhone off by depressing the off-but on the top right and hold it down until the question of do you really want to turn the iPhone off or cancel.
I normally cancel and the iPhone seems to come back to life. When it does not, I repeat and then turn the phone off. And back on again.
This is not a reset and it is not fixing anything, just seems to trip the silicon triggers and let's you get back to work. In my mind this is a software bug on the iPhone side of the equation.

Iphone freeze, need help

I have an iphone 4.
Since this morning i can not do anything with it.
It is impossible to enter my pin number to unlock it. I did a full restore of the iphone and i still have the same probleme.
This is some pictures of my pb:
The slide works well but once i do it i have to wait 1 minute before to get the keypads display:
With this display, i have no answer from the keypad when i want to unter my pin number and after 2 min i still have the first picture with "slide to unlock".
Please, someone could help me? thank you.

Thank you for your help, i hope i could get a solution as soon as possible.
I had the same problem 2 months ago, and after one week, i dont know why my iphone was working very well.
The sim card is ok ( i think) because it is a new one (3 months Old). I made a reservation on an apple store today for a diagnostic but i have to wait until next thursday.

Mac pro display freezes need help.

My mac display freezes after a few seconds of turning on. Ive had to unplug or turn off to turn it on again. Now, it just wont do anything after I enter password. It just freezes. The screen is also very hot.

Did you follow this procedure exactly...
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
...this will reset the SMC (System Management Controller).

wow loads of answer:)
after setting noapic and disabling hpet, i didnt noticed any more freeze
but i wasnt able to read a simple divx with vlc too much frames drop.
so removed those.
the laptop has a few years and wasnt acting like that before (used debian on it during the 2 last years)
about the temperature
cpu is about 80 degrees when freezing and hddtemp says something laround 55-60 degrees
for the memory, i have a laptop which reduce the chance to find a stick quickly. but i ll follow your idea and will try a memcheck
cat /proc/interrupts says

so i guess there is no IRQ mistake
what i dont understand is why an error about sound caused by a possible hdd overheat when compiling result in computer freeze ^^
i ll be away today, but will keep the post update later this week, if i find anything to fix or to narrow the problem
thanks all of you anyway for your time and answers.

K7t266 pro2 ru freeze

Hello.
I purchased this motherboard on 2002.
This is my config:
Hardware:
Mobo MSI 6380 k7t266 pro2 ru (via kt266a chipset)
CPU AMD Athlon 1800+ Palomino core (no overclock)
RAM Kingston DDR PC2100/266 MHz (no overclock)
Videocard Triplex Millennium Silver Geforce 4 Ti 4200 64 Mb Ram (no overclock)
Analog TV card miroMEDIA PCTV
Digital Satellite TV Card Hauppauge Nexus-s (has mpeg2 hardware decoder onboard)
sound card CMI/C-media 8338 4ch (mobo's internal AC97 disabled)
ISDN TA card Asuscom PCI internal P-IN-100 ISDNLink
Software:
Microsoft XP SP2 slipstreamed, totally "windowsupdated"
Via drivers 4-in-1 "Hyperion" 4.51 installed (latest)
Promise FastTrak 100 Raid controller Driver 2.0.0.0 (latest)
Nvidia drivers Detonators 56.72 WHQL installed (not latest but working very well)
C-media driver for 8738/c3dx 5.12.1.0 (forced but perfectly working! and latest)
Bt 848 generic BtPCI WDM drivers (for the miroMEDIA PCTV, but tried even with pinnacle 4.* VFW drivers and 5.* WDM drivers)
Hauppauge Drivers 2.18c (latest)
The problem is this:
when i'm watching tv, from the analog or the digital card, if i do something on one of the hard disks (on the raid or not, ntfs or not), like transfer file, search a file, or something very HEAVY that requires high data rates on the hdds, the system freezes, EVERYTIME!
I read on this forum about the pci latency unofficial patch by george i-dun-remember-who, but even installing it, it didn't help.
What i must do? The system works not so bad in other situations, so how can i fix this problem?
I get mad when the system freeze 'cause i need to hard-reset everytime and i think this can do damage on xp files :(
Please, if anyone has this same problem and fixed it, help me!!!
Thanks in advance.

Hi there.
@Fredrik Åsenius:
Look, i was wrong about cas latency, it was 2,5 set by SPD, not 2. For the HD disks, they are ALL cooled by fans of 4x4 or 5x5 (cm), that i obviously clean regularly, so you can understand that i touched they with the finger and they are kinda at ambient temp.
Anyway, this are the pci card placings:
Slot 1 -> empty
Slot 2 -> miroMedia PCTV card
Slot 3 -> Asuscom ISDN TA card
Slot 4 -> C-media/CMI 8338 audiocard
Slot 5 -> Hauppauge Nexus-s DVB-S TV card
More infos: like i said in the first post, I ever installed from the beginning, that means when i fresh installed xpsp2, the "PCI Latency timer patch" from George Breese (now i remember him ^^) from this page http://www.georgebreese.com/net/software/#PCI, but didn't help.
Actually i followed the hint from MGP, and a little more, so i tried to enable wait states, delayed transactions and stuff, and disable fastwrite, low agp x factor (from 4x to 2x), even highen PCI Latency timer in the BIOS to 248, the maximum, and seems that the situation is better, i tried to watch tv (from the Nexus-s with Progdvb) and do a search on all my hd, the system didn't freezed and the video didn't glitched as before. Only when i ran the PC Alert's Cooler XP, continuing watching dvb-s tv and continuing searching, the system freezed. Well, a little better but i'm investigating some more: i was asking and googling if there's a PCI test bench software but had no luck, a guy from irc told me to try Sandra and Aida. Actually i tried Sandra, the latest, and read about the pci card infos.
I found an interesting thing: not all pci card have the same PCI Latency timer, there are some that has a personal entry. I googled for PCI Latency timer again and found a program named PCI Latency Tool 3, that let you set every card's timer separately. This program shows exactly the same settings as Sandra, so i'm sure that is good working ^^
Actually i reset the timer at the default entry, 64, and this is the entry list of every card's PCI Latency timer:
miroMEDIA PCTV -> 64
Asuscom ISDN -> 16
C-media/CMI 8338 card -> 64
Hauppauge Nexus-s -> 255
This are the timings of the other pci related and mobo integrated devices:
CPU to PCI bridge -> 0
PCI to AGP bridge -> 0
PCI to ISA bridge -> 0
Controller IDE VIA BusMaster -> 32
Promise Fasttrak 100 Raid ctrl -> 32
Microstar (NEC) USB 2.0 ctrl -> 64
Nec Usb ctrl 1 -> 64
Nec Usb ctrl 2 -> 64
And finally this is the timing of the AGP card:
Nvidia geforce 4 ti 4200 agp4x -> 248
I dunno if there's something wrong so i didn't changed anything, but i think that's the Nexus-s timing is really high and over the maximum allowed by the mobo, so can be this the problem cause... if not i dunno where to hit my head
@ osnavi:
No, i dun think can be the power supply not enough, i dun have a friend with a better one but i tried uninstalling all the others cards (sound, pctv, isdn) and all the other Hd and the dvd-rw too, so only the basic needed to try: mobo + cpu + ram + agp card + dvb-s card + 2xhd 80gigs, and did exactly the same... well, i dun think now that 17 A is not enough, even if it's not so the minimum... Ah, did i said that it did the same even with a "low power" gefo2mx ? well i'll write it again :p ^_^
@MGP:
I know that's not an MSI fault and is a Via fault... but it got me sad, cause i like MSI hardware and stuff, but this bad experience, and more of this no support at all from the manufacturer.... well is no good :p
For the other things look above, i tried but i dun think agp stuff is related.... I think that is pci latency related, cause i know that i.e. eide or raid performances are not so good. Thinking that when my issue pops out is exactly when i'm watching tv and doing hd stuff, that means poor eide or raid.. or pci performance, than here comes out that it can be only this the cause.
Ah, i dunno if i told you all, guys:
watching tv from the pctv analog card (and i mean at maximum resolution of pal 768x576) or from the dvb-s card (with hardware mpeg2 decoder that means 720x576) means that there's needed a maximum bandwidth of 32 MB/s (it means: 768x576 for frame x 25 frame per second x 3 bytes color (32 bits/8 =3 bytes) = 32 megabytes for every second), that's pretty much, but not to saturate pci bw. The matter is when 32 MB/s is occupied and the eide or raid needs bw: the chipset seems to freeze cause can't manage well the bw needings, and so is related to the latency timer.
Sorry again for longness ^^

HELP! k7t266 pro2-u winxp install

Hi,
I have a problem with installation of winXP SP1 on my computer. First i got a blue screen in the first step of installation (windows loads drivers, then freezes). It said that acpi.sys is the problem. I disabled it and then the problem was irq not less... . Then i disabled
internal cache, system bios cacheable and shadowing options and installation started but the computer was too slow ( it took about an hour to copy the files on hard disk). After the installation was finished i put back the fields internal cache to writeback and c00 32k shadow to cached and left system bios cacheable on disabled ( i read in the manual that it might be a reason for system hangups) to speed it up. For a while it seemed like it was working ok, i installed the drivers, software... but tomorrow everything up. windows started to freeze when i tried to encode mp3's from audio cd's, when i tried to install new sofware...
I dont know what to do and don't want to disable internal cache because of the huge system slowdown...
Can anyone help !!!
my config is
amd athlon xp 1800+
microstar k7t266 pro2-u with lan

Hi!
What can your PSU provide in terms of ampères?
Load BIOS setup defaults. Open case.
Have the HDD and the CDRW on different IDE channels and cables, with both as Master respectively at the end of the cable.
Install VIA 4in1 drivers.
When everything works, make proper BIOS adjustments.
Best wishes, and good night!
Can't provide the data about my PSU because i'm not at home right now.
I will do it tomorow.
Cables are already set up like that.
Thank you

Need help with my iMac ... it keeps freezing up on me no matter what I do.

Hello all,
I need help to figure out why my iMac keeps on freezing up on me. I used to have Norton SystemWorks installed but I recently uninstalled it because I found out it was poison to Mac OS X. I've used Memtest to check the memory in my iMac. The result of the test came up fine.
You can go to 'Cooling fans for iMac?' (one of my post) to read all of the solutions I have tries out. This post is the original post to try to fix the problem but it FAILED.
In the last week, I've backed up all of my data to my external hard drive. Then I totally erase my internal hard drive and made sure to zero out the drive. After, I proceeded to install Mac OS 9. I had some problems installing the system at first. I finally installed Mac OS 9 and upgraded it to the latest version of 9. Next, I tried to install Mac OS X 10.3 with difficulty. I then finally installed it. I notice during and after installing the both OSs, my iMac keep on freezing. After I installed Mac OS X 10.3, I updated the OS. And yes, while updating the OS, I've experience the same problem as before. I now have my system back to where it was before I did a fresh install of both Mac OS 9 and X.
You guest it, my iMac is still freezing up on me no matter what I do. Can someone please help me with this problem? Can he/she tell me what is going on with my iMac and how to fix it? All the help I can get would be appreciated. Thanks for you time and effort.
P.S. After trying all of the previous suggestions from other users, I came to an conclusion that one of the hardware in my iMac my be failing. I know for curtain it is NOT my memory. It my be something else inside my iMac.

I've read the thread you linked to above and the only thing I find missing in the saga is any mention of the PRAM battery. If it is depleted (and it would be getting close to depletion if it has never been replaced) it could be causing your problem.
Do you see any strangeness in the time or date displays? That would be a sure sign that the battery is dying. I haven't run into the problem of a bad battery causing constant freezing but it wouldn't hurt to check it out.
As far as temperature effects, the usual pattern of overheating would be a shutdown of the whole computer, a designed-in precaution.
Forgive the battery tutorial if you've already dealt with that possibility.
