RAM Not Recognizing

Feb 5, 2008

I recently added 2GB of RAM to the 2GB I already had installed. My system is showing the RAM as being there in my BIOS, but, when I run DXDIAG only 1GB is showing out of the 4GB I have installed . Is it because of the Windows version I am running and if so, what can be done?

Not Recognizing My 4GB Of RAM

Jul 31, 2006

I have Windows XP Pro installed with all the updates. I have an Asus P5ND2-SLI Delux motherboard (it takes DDR2 533 and 667 memory). I had 2GB of DDR2 533 memory; I removed those and installed 4GB of DDR2 667 RAM (Kingston KHX5400D2K2/2G). When Windows XP runs, it shows 2.25GB of RAM only!! The BIOS sees 4GB of RAM and I ran Asus PC Probe and it sees all four 1GB modules (a total of 4GB) ... what shall I do to get XP to see the 4GB of RAM? Shall I reinstall?

Recognizing Drives As SCS?

Apr 21, 2005

I have a Samsung SATA hard drive, a Sony CRX225 CD-RW and a Plextor PX-708A DVD-RW. I hadn't used the burners for a while, now they aren't working (can read from them but most of the time won't write). In the device managerdriveproperties, Win XP sees them all as SCSI devices. How is this possible? The BIOS has them as IDE primary and secondary drives, so where does the SCSI come in? Could this be part of the burning problem I am having?

CD Burner Not Recognizing CD - R?

Feb 16, 2006

I recently turned off a lot of XP services that I thought I didn't need so that I could free up some CPU cycles for my flight simulators. Now, when I try to burn files to a CD, I get a message telling me to insert a CD-R into the drive? I'm using the program built into Win XP and it seems to start normally, it's just not recognizing the CD-R. Strange, but the CD burner was recording fine until I turned off the services. It plays fine otherwise. I've tried turning services back on but no luck. Does anyone know which service may enable this function?

Programs Not Recognizing OS

Nov 17, 2007

I'm having some problems with installing certain programs on my computer, like Windows Live messenger and Windows Blinds. For some reason they're not recognizing the Operating System as Windows XP. Since the newest versions of the programs only run on XP or higher. This is strange because i know for a fact that I have XP Home SP2, I've had it for like 4 years or so.

Now, it's strange that this is happening because I had Windows Live messenger before, I wanted to try it out and I didn't like it so I downgraded back to MSN messenger, but now all of my friends are using Live and some things just aren't compatible with both like the Video convo thing. I tried reinstalling it but it says that I require to have Wind XP or Later, same thing happened with Windows Blinds 6.0. I tried installing Win Blinds 5.0 or something like that and it worked perfectly fine, because it's compatible with lower versions of Windows such as 2000, NT and ME.

PC Not Recognizing Mouse

Jul 25, 2008

My Dell Dimension desktop is running Win XP Media. A few days ago the mouse simply stopped working and on a reboot it did not fix it. I was using a wireless keyboard and mouse and noticed the light was not coming on on the receiver/transmitter so thought that perhaps that might be the problem. At the time I did not have another keyboard with a usb plug, my childs pc had a ps2 keyboard and i do not have a ps2 port. So I used my childs pc and my wireless keyboard and mouse work perfectly on it, including my transmitter/receiver.

The problem is obviously not with the hardware since they do work on her pc. I did however purchase a new keyboard and mouse - usb this time. I get the same issue. The keyboard works fine as I am able to boot in safe mode, enter the set up etc and can move around in those screens. As soon as it hits the XP log in screen though I am screwed, the keyboard is useless and with no mouse I am unable to click on my user name to log in...............

PC Not Recognizing Ethernet

Jul 25, 2010

my mother discovered the internet 1 year ago and now she's addicted to it and is going crazy without it! My sister unplugged her Dell PC, to move it, and for some reason the computer now isn't reading the Westell Modem for the internet. Called the ATT ISP and we figured out it wasn't the ethernet cable, instead, its the PC which just isnt reading the ethernet to get on the internet. When I did IPCONFIG the IP Address doesn't show up. This is basically what it says: c:Documents and SettingsDiana Cresswell>ipconfig.........

System Recognizing DVD-R And CD-R/W Both As CD-R's!

Aug 24, 2007

I just put an old win2k hd back in my computer and the DVD-R and CD-R/W drives are recognized as CD-R's (i.e., when I click on My Computer, I see two cd drives). These are a couple of el-cheapo drives I got from CompUSA which actually work really well. I can't find the driver disks which came with the drives so I don't know what to do.

DVD-RW Drive Not Recognizing Blank CDs?

Mar 22, 2009

my dad's Dell Dimension E310 is not recognizing blank CDs! I tried rebooting a few times (my girlfriend's computer had a similar problem, and that fixed it on her computer), but that isn't doing anything. The warranty for this computer expired 2 days ago, so I can't get help from Dell unless I pay them... does anyone know what to do?

Computer Not Recognizing D & E Drives

Dec 13, 2004

Over the weekend while doing some electrical work, I shut off the power to the room containing my computer. I had a hard time getting it to Start Up, but all seemed fine accept I had to re-set the clock. Then I shortly discovered that it would not recognize either D: or E: drive, I finally did get them both to recognize an audio cd but only after opening them through WMP. Usually they start when placed in the drive, and it will use my default player (Nero). When I looked in "My Computer" it prompts me to insert a disk ?? I am running Windows 2000 NT Pro and the C: drive seems to be operating fine.

RAM Recognizing Half Of Original

Oct 16, 2006

So installed WinXP Pro on my 3 month old HP pavillion personal computer and I am having an issue with the ram Apparently windows is only recognizing half of it.Here are some of the most pertinent details: AMD Turion64 ML-34,Radeon Xpress 200m w/128 MB on the video card.There are 512 MB installed DDR, Dual Channel.The bios is recognizing all 512 of the ram, but windows properties only shows 256.dxdiag also shows 256, but CPU-Z shows all 512.Does anyone have any idea whats going on? Has anyone actually experienced this phenomenon? I don't know if this is just a reading error, causing no performance difference, but I think I can feel the difference, but since its pretty new and the operating system has only been installed for about 2 weeks, I haven't gotten to get a good feel of what its supposed to be. I have also noticed in the past couple days that it takes a very long time to boot.

Not Recognizing File Systems On Drives

Aug 23, 2005

I have a Western Digital 20 GB secondary internal hard disk as E:. It has been working fine for the last two years. Recently, while trying to access this disk, Windows displays message, "The disk in this drive is not formatted. Do you want to format it now?" When I insert a CD into the D: it spins for ~5-10 secs but then shows nothing in the right pane of Windows Explorer. Does not even give me the usual prompt to, "Please insert a disk into drive D:". It doesn't hang Windows Explorer, just sits there with D: actually selected in left pane. This is particularly odd as normally one would get the "insert disk" prompt. To test for drive readability, I successfully *booted* from the Windows XP installation CD-ROM. It read the CD fine so not a defective or broken CD-ROM. This also rules out that maybe the CD I inserted was bad or had
scratches.

When I insert either om my two SanDisk USB 512MB flash, Windows Explorer "assigns" it a drive letter but does not show it as formatted, ie- "The disk in this drive is not formatted. Do you want to format it now?" Even if I do select to format the drive, the format process fails. This drive has beeen tested on two other WinXP installtions and works fine......
