  • KT2 Combo beeps and then powers down with XP2400

    Hi all I could really use some advice here.
    I bought an XP2400 Tbred cpu for this system and it never worked. I ended up returning it since it I think it was DOA. But I wanted to confirm it. The 1GHz Duron I have in it runs perfectly.
    This system has a 100/133MHz jumper so when I installed the XP2400 I first removed the old 1GHz Duron, I then cleared the bios and set the jumper to 133 and then turned it on. Upon booting up it beeped 2 times VERY quickly and then shut down. One normal beep and one quiet beep you could barely hear but was there. No matter what I tried that's all it would do.
    I have an Antec SL350 which does 35 on +5 16 on +12 and 28 on +3.
    http://www.antec.com/specs/sl350_spe.html
    With only the cpu
    2 sticks of 256MB PC133(I tried a single working DDR2100 stick as well)
    NO drives connected
    and an old PCI video card( I started with my FX5200 but went PCI to test)
    I know the mobo supports up to 2600+ 266MHz bus but with the XP2400 it just turned on, never POSTED, beeped and then turned off. My other system, a K7TPro2, is chock full of gear and an XP2000 runs fine with a lesser supply.
    Was the xp2400 DOA or is there something amiss in my system? Ie does anyone know what those two short beeps were. If my Power supply is indeed weak what should I go with? A Xp2100? Many thanks for any help here as I need to order a new cpu but I'm afraid I'll run into the same problem if i order another 2400.

    Wow, thanks for all the quick responses.
    Dr Stu, No ,100MHz made no difference and my K7TPro2(not A) would not support it. I have nowhere else to test it so I RMA'd it.
    osnavi, as others pointed out its actually a decent power supply. I've seen plently of reports of people running this class and faster CPU on my Power supply, especially considering I stripped the board when I was trying it out. It is of course possible that my Antec has bad CAPS or is dying, but nothing else points to that.
    Grayone, nice link. Your right, too bad it never stayed powered up long enough. At best it was one clear beep and part of a 2nd one, but that was it. It powered down within a few seconds every time I turned it on.
    My main concern is which cpu to buy. Since this is my HTPC and its running Windows Media Center 2005 I wanted to get the fastest CPU possible. That's why a XP2400 seemed perfect. Now I guess I need to see if I can find an old XP2100 so at least I can cross test it in my other motherboard.
    Still though, its always going to bother me that I'll never know if it was my motherboard or the actual CPU that was the problem. Thanks again.

  • IPod beeping and then freezing up

    I have an iPod mini (2nd generation). When I try to download songs from iTunes my iPod will suddenly start beeping (4 beeps decreasing in pitch, then repeats the fourth beep twice) and then it freezes-up iTunes. If I force quit iTunes, then neither iTunes or my computer recognizes the iPod. I usually get the sad or unhappy iPod icon on the iPod screen, but if it is still plugged into the computer I can also get the monochrome non-animated version of the battery icon. Once I go the folder icon with an exclamation point. My battery is fully charged. If I wait several hours I can reset my iPod, hook it to the computer and maybe get several dozen songs downloaded before the iPod starts beeping begins and then whole thing freezes up again.
    eMac   Mac OS X (10.3.9)  

    - Reset all settings                            
    Go to Settings > General > Reset and tap Reset All Settings.

  • Mail default signatures deselected every now an then

    I run signature sync via MobileMe to use them on iMac, MB, iPhone and iPad.
    Now, since some weeks I experience that the signatures are the same from content, but lets say one or twice every week there is no default signature selected, so that I have to reselect it.
    This happens on iMac and MB.
    Its solvable but I hadn't had this problem since I started with the additional iMAC I newly bought. May be just an coincidence, may be a new MobileMe/OS-problem?
    Help would be very welcome.

    Try this - find the /Library/Preferences folder in your user/Home folder and then locate and this file and temporarily move it to the desktop:
    com.apple.mail.plist
    *Caution* - doing this may clear your account settings so be sure to note those first in the event you are required to reconfigure, etc.
    If this fixes the issue, you can delete the original plist---if not and you want to short-cut making any needed settings as before, delete the fresh plist and move the original back to where it was.

  • My Firefox hangs every now and again for about 30 seconds. I get a message saying it is not responding and it's driving me mad! Only happened recently, haven't done anything major to my computer in that time.

    I did recently mess things up with a Vaio update and my computer then wouldn't do anything, wouldn't connect to internet etc. I did 2 system restores and it now seems to work fairly well apart from this hanging business.

    The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
    Try to decrease the value of the pref <b>network.http.max-connections</b> from 256 to 30 as used in Firefox 3 versions.

  • Macbook is making a loud BEEP and then freezes

    Hello,
    Recently my computer started to randomly make loud beeping sounds and freeze. the only way to stop this is by holding down the power button on the computer and starting it up all over again.
    What is going on? Is there a way I can stop this?
    Please help I am very worries
    Thank you

    It may be a RAM issue.  Open the MBP and take out the RAM chips , clean the contacts with alcohol and reseat them, firmly.
    If no success, run an Apple Hardware Test:
    http://support.apple.com/kb/ht1509
    You may have to start it with the OPTION and D keys.
    Ciao.
    It is helpful if one indicates the model MBP and OS one is using.

  • IMac gives three beeps and freezes

    My neighbour's iMac starts and runs normally most of the time, but periodically when running emits three beeps and then freezes. This is NOT the usual "three beeps at startup" indicating a RAM problem, but whilst the machine is is actually being used.
    Can't seem to find anything about this anywhere. Any ideas, anyone?
    (The logic board was replaced very soon after purchase as the machine had all sorts of problems . . .)

    My imac mid 2010 worked fine with "new" memory for 6 months, then started hanging in mid-session - meaning it froze and beeped loudly hours or days after it booted OK. Put old memory back in and noticed it ran more smoothly with less memory than more. Put the "new" memory back in and ran memtest for days and days; no problems reported. But, the system still froze after I'd been working for a while - at odd times. So, took the "new" memory back to the store, and, while there, upgraded to (more expensive) Crucial brand memory - just to be on the "safer" side. Put the replacement memory in and my imac has never run better - not even when new. So far, my imac is quieter, cooler, and smoother now than since the day I bought it. Thought I'd post this on this old thread because Apple Care had told me to bring the machine to them for three days of testing - per other posts I'd seen on the net. But, that would have been a complete waste of time - since they'd wind up (with the old memory) telling me "no problem," or, (with the "new" memory,) "it's a non-apple part problem." Meanwhile, bad memory can mean bad writes to your hard drive; mine seems fine, but I generally pay close attention to problems and fix them asap, or, sooner. If you wait until you have additional problems, you may spend a lot more time and money getting things finally done - and you may wind up back at "square one" or worse if you trash your drive and it's contents.

  • Firefox won't open after update, black screen, beep and "do you want to allow program to make changes..."

    Updated Firefox yesterday and now the program will not open on my desktop. Screen goes black for a second, issues a beep and then get box asking if I want to allow Firefox to make changes to my computer. Does not matter if I click yes or no, box disapears and nothing happens. Willing to remove and reload the program but hate to lose all my bookmarks.

    '''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
    ''(If you're not using it, switch to the Default theme.)''
    * You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
    * Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Don't select anything right now, just use "'Start in Safe Mode"''
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''

  • Spilled coffee on my macbook and now making beep and quieter.

    I recently spilled coffee on my macbook and then the hardrive stopped working so I removed the hard drive and saw that it was covered in sticky old coffee. Then I bought a new hard drive and put it in.... The hard drive didnt show up when trying to install mac os x!!!! :O
    Now I was thinking it could maybe be the hard drive connector but iunno.
    ALSO when i boot it up it takes REALLY long to get to the menu screen for installing mac os x!! AND it also makes a wierd noise like this... beep beep... beep beep... every few seconds!
    Anyone know what could be wrong?!?!?!?!?!?

    Nobody can tell you specifically what to do next. There could be so many things wrong.
    You probably ruined some components in the process and I think it's permanently damaged. If you're handy, you could try to repair it yourself, but this might be an arduous process. The procedure would then be to isolate the components that are causing the slow boot and the beeping. The iFixit.com site is really good for this, with spare parts and repair manuals.
    You could also try to sell it on eBay (as broken, just for parts) where it might still fetch you a nice price.

  • My iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat,  every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats??

    hello my name is kirstie, i updated to firmware 4.2.1 .....my iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat,  every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats the same problem??

    (i correctly got out of dfu mode after the downgrade)
    i can enter dfu mode and recovery, and update through itunes with no problem, but it doesnt fix the problem,
    i have searched and found no answer to this problem, every option availible to try that i know of i have tried and failed. i dont care about preserving my content i just want a fix. i have a good understanding how to operate software on a computer and shouldnt be too confused by any advice given, so plz even if the answer is very complex i wish to try anything, please help me to get my iphone working.

    Anyone have any suggestions? or is everyone else just as clueless as me !

  • Every now and then I get about a half second clip of another song

    Every now and then I get about a half second clip of another song at the end of a song. If you immediately go back and play the same again, you get the same little burp at the end. But if you play three or four songs and then go back, the little burp is not there. I did a restore on the ipod, and I am still getting the little burps. It only happens maybe once out of every 10 songs played.
    Files are MP3's which play fine on the PC in WMP and itunes, and on Dell DJ15, Zune and Sansa MP3 players. Some of the MP3s were ripped from CD using MusicMatch, some recorded off old lps using Creative Go!, and some downloaded so I don't think it is an issue with the MP3s themselves. Since I use several different players, I don't want to maintain a separate AAC library just for the ipod.
    Usually the burst is so short that you can't even tell who the artist was, but when I have recognized it was always something very close alphabetically - at the end of a Cream song I got a little Creed, at the end of a Bad Company song I got a little Bachman-Turner Overdrive, at the end of a Led Zeppelin track I got a little Linkin Park.

    Does this help?

  • Every now and then (every 15 minutes-half an hour or so), my internet fails. It says in the Diagnostics that the internet and server have failed. Happens on my sister's mac as well. Is this our modem?

    Every now and then (every 15 minutes-half an hour or so), my internet fails. It says in the Diagnostics that the internet and server have failed. Happens on my sister's mac as well. Is this our modem? Our PCs don't do this so it has something to do with the macs.

    Hi Patrick,
    I'm starting to think it's either an AirPort card issue or something to do with the Mac OS. I have stopped using wireless as much as possible in my home (have wired up several new Ethernet outlets), and it sure is nice having Internet run at the speed it's supposed to all the time, and with no drops. Might be something to consider.
    In the meantime:
    Open System Preferences > Network > select AirPort > click on Advanced > TCP/IP > Configure IPv6 > Off > OK > Apply > Turn AirPort Off > Turn AirPort On
    Open System Preferences > Network > select Ethernet > click on Advanced > TCP/IP > Configure IPv6 > Off > OK > Apply
    (FOR LION: If you can’t see an option to turn ipv6 off, set it to link-local only.)

    Hey, There are afew things you can try.
    - Simply turn your phone off and back on again
    - Hold down your home button and your lock button and let goes as soon as the screen goes black (Phone will power down) - Then turn on your phone and hey presto!
    - Back up your iPhone to your PC, then restore it..
    this ones last cause I think you may have tried it already..

    Hope this helps!

    Those are the instructions for your computer's iTunes (i.e. using the Store menu at the top of your computer's iTunes and selecting 'View My Account' on it). If you are doing it on your iPad then are you following the instructions for iOS devices :
