K8T Neo creates 'phantom' RAM and won't recognise the real stuff...
I have just replaced my computer's motherboard and CPU, from an ancient ASUS A7V266-E motherboard and an AMD XP CPU (1.1GHz) to a new K8T Neo-FIS2R motherboard with an AMD Sempron 2.0GHz processor, both brand new. I thought that it would be possible to use all the other components until I can save up enough for a new graphics card, RAM etc.
All of the other components seem to work fine. After making all the connections and starting up for the first time, Windows (XP) loads successfully... but VERY, VERY slowly.
About an hour after loading, I finally manage to right-click on 'My computer' to be told that I apparently have "AMD Unknown Processor - 2.0 GHz" and "64MB of RAM".
This is what surprises me, because in the DIMM ports at the time were three 256MB PC2100 DDR sticks, all three identical - two which were in the motherboard I had before (sequential serial numbers and everything), and another one from another PC purchased at around about the same time. All three worked fine in their old computers. So not only is the PC not recognising that it's actually got 762Mb of RAM stuck in it, but it's creating 64Mb out of nowhere!
AFAIK, the sticks should be compatible, because the RAM specifications appear to be the same for both the Old ASUS motherboard and the New K8T Neo - check out the specifications on the left-hand-side for each board. However, clearly something is not right - it could be a compatibility issue, or is there something I'm missing?
All it says on the sticks of RAM is "256MB PC2100 DDR MEM" (plus "Made in Korea", of course ), but crucial.com seems to be telling me that the RAM must be SDRAM, because that's all that would work in my old motherboard. Is there some other configuration issue I've overlooked?
I've tried swapping the sticks around and taking some of them out - no change, either in the display or in overall performance. I tried loading it with no RAM at all - didn't like that one bit! I had a look through the BIOS (with the instruction manual close to hand), but nothing jumped out at me - and I really don't know what I'm looking for!
Really confused! Any ideas what's going on? Any help would be much appreciated.

Check with memtest86
...yeah...
...look on the bright side...when I tried PC2100 RAM with a Socket 754 CPU it wouldn't even POST...
...you might have to enter BIOS and configure the RAM manually rather than Auto...just a guess...

I have just started using a windows7 64 bit machine which is an LG emachines model. I have latest version of iTunes installed. When I connect the usb charger it says I need digitally authorised drivers and won't recognise the iPod. Does anyone know of a fix?
Thanks

When trying to download apps on my new iPad I keep getting prompted to update my security questions for my safety. When I choose this option it freezes and won't load the questions, however, when I hit not now it won't let me download. What do I do?
Reboot your iPad and then see if you can set the security questions.
Reboot 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. -
I was recently prompted to update iPhoto and make changes to the library. I did it but it keeps hanging up in step 5 or 6 and won't complete the cycle. I have used force quit, rebooted and started again several times. How do i get this to work?
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
If that fails:
Restore from your back up, repair the Library and try again. -
how to check the usage of ram and cpu Performance for the particular application like sqlserver ,ms word
rankiHi,
You can use Performance Monitor and add the required counters.
Check the below Technet article on Performance Monitor.
http://technet.microsoft.com/en-us/library/cc749249.aspx
Below are the steps to monitor the process in Performance Monitor.
- Go to the Performance Monitor.
- Right-click on the graph and select "Add Counters".
- In the "Available counters" list, open the "Process" section by clicking on the down arrow next to it. Select "% Processor Time" (and any other counter you want).
- In the "Instances of selected object" list, select the process you want to track. Then click on "Add >>" button. Click on OK.
Regards,
Jack

A friend gave me an iPad 1 last week. Messaging works one day and won't work the next. Any suggestions?
Hi,
I have the same problem. I've been trying everything; opening ports, adjusting quicktime streaming preferences...everything discussed in other posts in this forum regarding error -8.
I really hate iChat...I think it's unbeliveble that Apple claims to be so better that Windows, but I never had problems wits MSN video.
But let's try to solve this irritating issue. What kind of messenging software do you have instaled/open when you try to use iChat?
I have Skype installed. When I deinstalled it, everything was working fine (so I thought). Next day the same BS all over again.
I could use skype to videochat, but I have an .mac account and I want to use iChat...the f&^%$*g .mac account is to expensive not to use...And do not forget that iChat AV quality is way better than Skype.
I really hope Apple comes with a solution soon.
Greets from an unhappy iChat user.

My home movie DVD folders all have red circle with white dash and won't allow the files to be read. Is there any way around this so I can back up the DVD's on a external HD?
Drag the folders to the external drive, and if prompted, click Authenticate. You'll probably be asked for an administrator password.

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..
Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions.. -

Mac won't recognise the CD in the Optical Drive
My MacBook Pro won't recognise the CD in the Optical Drive. So I can't eject it put new one in.
Why is doing this? How do I solve the problem and get my CD out?Are the CD's you are trying to install store bought CD's?
What you might try doing if the CD drive is not showing up under the source is going to file and then clicking on Add to Library within iTunes. Find the CD inside of My Computer and trying to add the music. -

The operating system can be found by going to the Apple menu and selecting "About this Mac"
Under "Mac OS X" should be the Version 10.6.x, clicking Software Update will update the operating system via the internet. -
