    Morning.

    I have to be quick as having huge issues today.

    The PC shut down as normal last night, not errors thrown up during the day.

    This morning, I switched the machine on and it started to boot up. It then hung at a message box "Video Input - No signal", then went back to the beginning of the boot. This happened 5-6 times. It then asked if I wanted to start in Safe Mode - I tried to accept this, but again it just kept rebooting.

    I eventually got it to start in safe mode, but yet again, it rebooted. This time, it took me to the normal Desktop.

    I took the opportunity to back up some documents onto a CD quick, halfway through, it reboots. No messages come up before hand, it's like I've just hit the reset button.

    I then managed to get it to stay on for about 10 minutes, did a few CD's and half a virus scan (just in case!). But the, you guessed it - it rebooted!

    I've now been on for 5 minutes, so will post this quick before the next reboot!

    Any ideas?

    Thanks
    A very stressed Karen!

    http://www.memtest86.com/ Has anyone used this before to check is the memory is bad?


    (Sorry for numerous messages - not sure when I'll be rebooted again!)

    Have you installed anything onto this computer (hardware or software) recently?

    Sounds like it could well be a hardware related problem.

    My partner hooked up an ipod to it last week, however it has been working fine since then, so I suspect this is not causing the problem.....although I could be wrong!!

    It's been on for 45 minutes now without rebooting.... :blink

    It was installed last week with version 4.7, then upgraded immediately to 5. No further updates since then. It advises if updates are available, but does not auto update.

    Good call! Just had a surf around the net and discovered that indeed, iTunes 5 is possibly the most corrupt piece of software available!! :rolleyes:

    I've found Apple's help forum, so will follow the guidelines to fixes.

    Cheers for that - I'm sure that is what caused the problem!

    While Ipid may very well be a very corrupt piece of software I doubt very much it has anything to do with this. Why? Because when this error occurs Ipod isn't even running. Windows isn't even running. Errors like this at boot time are normally hardware related errors.

    First, you need to check to make sure that the video cable is securely plugged in and the connector/s securely screwed down. Some monitors have a permanently connected cable at the monitor end and some don't, so make sure the video cable is securely attached at both the computer and the monitor.

    Second, you need to shut down your computer, unplug the power cable, open it up, and the carefully remove and replace your video card making sure it is securely seated. Make sure you use an anti-static strap when doing this. Do not touch the video card by anything but the edges.

    If you don't have one, buy one. They are cheap insurance because it only takes a very small static charge to ruin computer components. You can kill computer components with a static charge release 100 times smaller than a static discharge that you are able to feel.

    Third, while you are inside the computer case blow out all the dust and debris with air pressure. Make sure that you use the air pressure cans you can buy at just about any computer store or even at most department stores that have an electronics department. What ever you do don't just use the compressed air from an air compressor. Why? Once again static charges.

    If this doesn't cure your problem you most likely have a video card that's dying. However, you can double check this by hooking your monitor into another computer and seeing if it works fine there or not. If the problem follows the monitor, the monitor itself is failing.

    Not all hardware failures are "hard" failures. Some are "soft" failures, meaning that components will work intermittently for a while before they die completely.

    I'm inclined to agree with ffreeloader.
    I had a similar problem recently and connected it to a dodgy card and/or driver.
    I changed the card and ran the Nasty File Remover from guru3d.com to get rid of all my Nvidia files (need to do it in safe mode, and more than once). Then reinstalled a stable driver, if you can find one...
    61.77 seems fairly OK.

    This, and the memtest86+ version is about the only memory tester I have time for. It enabled me to persuade a system builder to replace the memory on this box when it was being flaky.

    I have both setup on bootable CDs.

    Karen,

    Just picked up on your thread. I agree with the "general" in that from the symptoms you describe it is probably due to a hardware issue. The trouble is these can be troublsome- i am trying to get to the bottom of an almost identical problem at the moment!

    This PC randomly locks up.
    I have removed one of the memory sticks and running it on one to see if i can isolate dodgy memory.

    hmmm i had a prob just like the above a few days ago at work... no ipod but worth a try... when processors overheat they restart so check all your fans in your pc starting with the processor and power supply.. do you have case fans?

    BTW i know the temp in the uk might not be great but with the heat here in cyprus - the fans more or less solve this problem for us so give it a try...

    Hi ffreeloader - thanks for your detailed reply.

    Very good point re iPod not even running at start up. :oops:

    I did this earlier and it is connected fine. I did think it may have been knocked when the iPod was plugged in.

    Since posting, the computer has been shut down and left for around 7 hours. I've just got back home and it booted up normally.

    I can't find my anti-static strap so will try this another day. Unfortunately my cat was hit by a car a few days ago and things have been a bit hectic driving her here and there for surgery etc. Need to find a day I will have a good few hours to take my time fiddling about inside the case!

    Also, ever since I have owned this computer (coming up 3 years) the last screen shown before it powers down is the "Video Input - No signal" message. Could this be relevant?


    Thanks hbroomhall - I too only like to use recommended progs!


    Hi Boyce - I'll race ya.....first one to fix the problem wins a, er, rather large bottle of vodka!
    [​IMG]
    Seriously though - hope you get it sorted.

    Hey Zimbo - not such luck in my house! It's bloody freezing! I had only just switched it on after it had been off all night, in a room that was prob around 18degrees. Will check the fan is working in any case though :biggrin


    Well, it seems this will be a good test for me seeing as I'm about to start the A+ course (if the book ever arrives!).

    Thanks for all the replies :biggrin I'll let you know how I get on.

    Karen

    It could be. It also may be that the motherboard is killing power to the video card before it powers itself down. I remember seeing that message on some very old computers, as in back in the 80286 and 80386 days. I didn't know much about them then as I didn't own one or work with them then, but I can still remember seeing that message on friend's computers when they would power down. However, I don't remember ever seeing that message on any "modern" computer that didn't have some type of hardware problem.

    That doesn't mean it isn't possible that your computer legitimately shows that message at shutdown, it just means I haven't run across anything like that in a modern computer. However, your boot time problems are not a normal occurence.

    IMHO Freddy, I encounter this quite often on perfectly working PCs (inc my home and work machines) - it is just as you say, the PC powering down the VGA output during shutdown. Wouldn't imagine this is anything to do with this problem.
