Q: Solved: New RAM not recognized - removed it now the old RAM isn't recognized


I recently added two sticks of new RAM to my computer, but when I turned it on again I got the two-beep "RAM Not Detected" signal. I removed the new RAM, but I still got the two-beep signal after turning it on. I've removed the old RAM, sprayed the area with duster, put the old RAM back and still have the same problem.

What to do? Thanks.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I tried replacing the hard drive on my Inspiron 9300 with a 200G drive.  The administrative computer tools in Windows XP recognized it, but the BIOS showed it as 130G or so.  I finally had to replace the drive with a smaller one.  I had the latest BIOS version.  Is there a BIOS fix that will allow the larger hard drive to be used?

I just rebuilt an old system using Windows 7 Home Premium after using WinXP pro for many years. The primary hard drive is WDC 150 Mg and Win7 is installed and updated to current with SP1. I dropped a second WDC hard drive in, formatted and was going to use it for a 2nd backup unit. Both of these are sata. Both hard drives are recognized by Disk Management but when I select Computer on the start menu ONLY the primary 150 Mg drive is recognized. If I plug in an external drive, both Computer and Disk Management recognizes the external drive. How do I have Win7 recognize my backup WDC drive so I can use it.

Thank you

Had similarities on my pc.

Goto BIOS, there you have 4 options.

Primary Master
Secondary Master

Primary Slave
Secondary Slave

Set it as follows:

Primary Master -----> Main Boot HDD
Secondary Master -----> EMPTY

Primary Slave -----> CD/DVD RAM
Secondary Slave -----> Secondary backup HDD
Hpe it helps!

I have a PC which is having a lot of trouble recognizing a USB data acquisition device. Starting from a situation where the PC *does* recognize the device, here is the basic pattern:

1. PC shows device in Device Manager under "Data Acquisition Devices".

2. If the PC is power-cycled via the power plug itself, the device is no longer recognized under Device Manager ("Unknown Device").

3. If the PC is power-cycled via Start Menu --> Turn Off, same results as above, no longer recognized.

4. If the PC is power-cycled via Start Menu --> Restart, no problems, device recognized.

When the device is not recognized, unplugging and replugging the USB cable makes no difference to the situation. In order to correct the issue, I disable and then enable via Device Manager (which also involves a restart).

This pattern is extremely repeatable.

I am working with WinXP SP2, Pentium, 2.8 GHz, 504 MB RAM.

This PC was returned from a customer site - the PC and USB device are used in a machine my company manufactures. Apparently this issue just started happening one day. We want not only to correct the issue, but in fact to understand the root cause and ensure it will not happen again in the future.

Any suggestions would be greatly appreciated - thanks!

JohnWill has fix that is worth a try

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

Hello all. It has been a while since I've needed help but my run of luck has hit an ugly downturn. Moved my computer three weeks ago and had not plugged it all back together till last night. All these years I had used it without a password to log in but a few months back a tech friend expressed horror at this so I started using one. Last night no matter what I did it wouldn't let me log in, saying incorrect password. Today as I messed around again I went through the steps of asking it to reset password (even though I didn't have disc for reset) and realized it does not seem to be recognizing my internal drive. If one of my externals are on they come up but if I turn off externals I get a bubble that says 'No Drive. This feature requires removable media etc.' My drive seems to be running and the Windows logos do appear during boot. My keyboard seems to be functioning to type password, but when I hit F8 while rebooting I get no reaction, so cannot boot to safe mode, just goes right back to log in page. I have had mold/moisture issues in this new house but have had a dehumidifier running since just a few days after computer arrived here. However I do see some evidence of mold or dust in the case, not a lot but some. Not sure what the root of this problem is but I am trying hard not to panic. Any ideas?

A:Internal drive not recognized/password not recognized

Your tech. friend may have mis-understood when you need a password.
If you are at home and only you and you trusted family have access to you computer, there is no need whatsoever for a logon password.
The only time I have ever needed one is when I was using my own laptop on clients site when I was contracting and I would leave it on the desk over lunch.

I have an old PC (Compaq Presario Desktop 7470 ) that i purchased from a yard sale. I removed the old HD and replaced it with a quantum 30gb at Lct 20 HD that had Windows ME OS on it. I booted the pc and it booted fine except windows booted up in 16 bit color. I shut down and booted again. same thing. i shut down a third time and checked BIOS settings, then set them to default. Now BIOS doesn't recognize the HD or the CD-ROM drive. I have checked all connection, reset BIOS, removed the CMOS battery, I literally have tried everything I can think of to get things going on this old PC, but I am at the end of my rope. I will say that scandisk will recognize the HD and says it is OK. I have also taken the HD out and hooked it up to another PC and it boots up Windows ME just fine. I have also tried every jumper setting on the HD and Cd-rom to no avail and the only drive that shows up in BIOS is the 3.5 floppy drive which will boot up a Windows ME Boot Disk. I don't have a problem installing a fresh OS but want and need the PC to recognize the drives before i can do that correct?
I am ready to pull my hair out!! Can anyone please help me?!!!?

A:HD recognized by scandisk but HD not recognized by BIOS

probably the booting sequence is wrong due to the fact that you told the BIOS to load the preferred defaults. If you have a standard BIOS:

*go to advanced BIOS settings.... your going to see a big list of options .

<< check this picture for visual example>>
*take a look at the first , second and third boot device and change them to:

1- HDD - 0
2- HDD - 1
3- HDD - 2

Alternate them accordingly.

**probably the reason why your pc booted up at 16 bit the first time , may be
because you haven't installed the drivers for your video card yet.

Hello everyone..
Yesterday my laptop pushed a new Win 10 update, and all went fine, or at least I think so.
But today I see that my Sony WALKMAN - which I used with no problem until now, can't be recognized anymore.

Basically it just shows as (E or Usb Drive E: but when I click it it says "Please insert a disk into E:/" like there is nothing there.

Now the interesting part is.. if I go to Device Manager I see it and clicking on properties etc t says it's working fine.

But if I go to Disk Management, the Drive shows as 14 gb of unallocated space and it's greyed out.

However, if I put it on my brother's laptop, it works perfectly and it can be opened, music moved into it etc - it shows as Healthy - Primary Partition in Disk Management. So it doesn't seem broken...

It's the same on each of the 4 usb ports btw. But, other usb devices (2 phones, 1 tablet) don't have any issue and are detected.

What could have caused this? I tried the basic Disable/Enable in Device Manager and also Uninstall Driver.. It doesn't do anything, it appears back when I replug it in.

No change in Safe Mode and no change after sfc /scannow

If anyone has any idea I'd be happy to try anything to fix this..


A:USB device not recognized on my laptop but recognized in other pcs/lap

This problem is being reported by many forum members with many different USB devices. It seems that Windows 10 Anniversary is having problems properly recognizing certain USB drives and devices. So far, no one has come up with a clear fix for this issue but it sounds like it is clearly related to the Anniversary update. For the record, I did a clean install and have not had any issues but most of the people reporting this problem make reference to updating to Anniversary.

Hello, I'm having trouble with my mic. I have a headset that has a mic and my computer doesn't recognize it.

Things I've done:Uninstall and reinstall sound drivers
Test the headset on other computers (It is identified and works immediately)
Plugged the headset into the front and back of my computer to see if it was the jack (Sound works fine, still no mic)
Contacted Turtle Beach support to see if there were compatibility issues or missing drivers. They said that the headset was compatible with Vista and no drivers are required from them
Did a system restart
Removed all USB devices and plugged in just the headset

The sound in the headset works fine. From my husbands computer to mine the only difference I can see is in the sound menu in his recording tab it lists microphone, line in, and stereo mixer where in my recording menu it says nothing is installed. So I'm guessing I'm missing drivers of some sort but am clueless as to which ones.

Any help with this would be appreciated. Thank you

I just upgraded my compaq presario 1701cl notebook from windows Me to XP Pro. The Problem is that I bought a PNY 256Mb attache flash memory that plugs into the USB port. It is not being recognized by the computer. Ive done the following: Uninstalled device and let it detect new hardware but it installs as unknown device, Os is fully updated with the exception of SP2, uninstalled the usb from the device manager and let it reinstall itself. PNY says that no drivers are needed for it to work in XP. It is 2.0 USB compatable. Ive used it on my other computer running win98 after I install the driver for it. I let a friend plug it into his machine running XP it worked fine. The only thing that may be the problem is the USB ports in the notebook are still v1.1 . How do I get it to work.

Hello hardware gurus!

I've searched through the hardware forum to avoid duplicate threads but I haven't found a situation quite like mine. I'm trying to reassemble my old computer as a backup. It is an old NEC 166. It was working before. It was partially dissasembled so that I could put my HDD and burner into my current new computer. For some reason the BIOS won't recognize the original HDD (Quantum Bigfoot 2.4GB). I have checked in the BIOS: auto-detect doesn't recognize it. When I boot up I get a HHD failure error msg. When I boot from a floppy and try to fdisk I get error stating that no fixed disk is present. I tried another old HDD (caviar 1.2GB) and got the BIOS to recognize it by manually entering cylinder head and sector info. It is listed in the BIOS on startup, but then I get the same HDD failure and fixed disk errors. To me this sounds like a BIOS problem. Any ideas?

BTW: I have checked all connections and jumpers numerous times and the floppy and CD drives are recognized and functioning.

In Device Manager, click "show hidden devices" and make certain there are no flagged devices.

Uninstall all flagged devices and reboot. Report results.

If that does not work, Uninstall the whole USB tree under "Universal Serial Bus Controllers", and reboot. Report results.

We assume USB is enabled in BIOS, but you never know. Be a good idea to verify this.

Disconnect all USB devices, and any other unnecessary hardware during the troubleshooting/repair proces, in case it is a device that is causing the problem. Get the motherboard working right first, then worry about the individual devices.


Did you install motherboard drivers for this machine ? Many people forget/don't know to do this. Even though the Device Manager appears to be working correctly, if you don't run the M/B drivers, things don't work; like USB.

Then I tried a new cd drive with all 4 of the cables. I switched all the jumper settings around on every drive with every cable. I checked each of the drives with every cable and every jumper setting in the bios and they did not appear there either. This happened once before but i just tightened the connections and it showed up again. I even tried a different power connector, but that was a last resort since i know that both the drives were getting power. I also tried the drive in a different computer and it worked fine. I'm all out of ideas on this one except to replace the motherboard. Any input and help would be greatly appreciated.

Hey everybody,
I've been struggling with this for several weeks... so I hope someone here can help me.

I have a Dell XPS 27, with a 32GB SSD and a 2 TB HDD.
I would like to configure this to have the OS on the HDD, and use the SSD as a Intel RST Caching device.

However, I tried to create a RAID0-volume so that the iRST-util would be able to set up a RAID array.
I know very little about RAID arrays and how to configure them to work properly.

Only thing I know, is this:
Whenever I boot the Windows disk with the BIOS in RAID-mode, it doesn't recognize my HDD, so I have to install the OS to the SSD. I have tried Loading Drivers from USB for the RST, but that doesn't help. In doing so, the PC fails to see the HDD even when the OS is installed without any problems. It doesn't show up in Disk Management, but it does however in Intel RST GUI. It shows my HDD, my SSD and 2 RAID0-volumes of each 30 GBs (which is strange, I think). See attachment 1.

However, when I boot the Windows DVD with BIOS in AHCI-mode, I can install to HDD (the SSD also shows up), but after installation, the SSD remains 'Unallocated space' with no pssibility to 'Accelerate' in the Intel RST Utility. That way, I feel like it remains unused. Also, when I reset the BIOS to Defaults, it turns to RAID, which makes me believe it has to be set up the first way I mentioned.

Could someone please help me with this? I have no idea how to properly configure a RAID-array and to get... Read more

A:Solved: OS on SSD, now HDD not recognized

Welcome to Tech Support Guy

May I start by saying I am NOT an expert on RAID
However RAID 0 works in such a way that the data is split into blocks and in simple terms half is written to one disk and half to the other.

Because both writes can take place at the same time, rather then all the data being written to one, there is or WAS before the introduction of SSD Solid State Drive a speed advantage

However there is no mirror and therefore no redundancy so there is no recovery if one of the disks fails
or data becomes corrupt

If of course, infrequent as disk failure is these days - generally speaking - if it is 1 in 5000, then forgetting the introduction of your SSD into the equation and keeping it simple it is then 2 in 5000

IMHO you are going about this the wrong way
You will have no noticeable speed advantage over and above the performance of the SSD alone in fact I think it will be less.

I would if it was me put the OS on the SSD and use the other drive for your data etc

I would ensure a full image of both drives existed together of course with the usual backup of the 2TB HDD

Hi everyone. Just managed to install XP on 1st new build. Yipee. Only 2.75gb ram showing when 4gb installed. Any ideas ? specs below



A:Solved: Not all ram recognized


I assume you are using WinXP 32bit, so basically the Operating System can only address a maximum of 4Gb of memory. BUT, some of this address space is automatically allocated to specific system processes.

Also Video memory has priority within this 4Gb of address space, so any RAM that you video card has (or shared) will also be pre-allocated. I had a quick look at the motherboard it shows an onboard ATI 4200 graphics card, I would assume from your information that this is using 1Gb of shared memory, not sure though.

So WinXP (32bit) can address (or access) 4Gb of RAM maximum. Take away from that the amount that is pre-allocated to System Processes, then take away any Video Memory (either on the card if it is an addon card or shared video memory), whatever is left is the amount of RAM the Windows will display as available, in your case 2.75Gb.

I hope that makes some sort of sense, but basically what the system is telling you is correct. You have 4Gb installed RAM but only 2.75Gb is available for general use.

I am running Windows 2000 SP4. I have 2 HDs in the PC. The second HD is not being recognized when I am in Windows. It is recognized in the BIOS and when I bootup.

I think it may not be formatted. How would I format it? I tried to put the Win2k CD in at bootup but I can only format and install Win2k on the drive doing that. Is there another way?

A:Solved: HD not recognized

Go to disk management; start>run type in diskmgmt.msc and hit enter. Right click on the drive and choose to create partition. Next right click on the drive and choose to format. Good to go.

Hello. I just transferred my Maxtor 30gig 7200rpm HD from my old computer to my new system.
I have it jumpered as slave to my primary WD 40gig 7200rpm HD.
I did not reformat the the maxtor since there are some files/programs I would still like to use. It has win98SE o/s in it but since it's the slave i don't think it should make a difference.
The maxtor is not recognized by my system.
What can I do, short of reformatting it for my system, to get my system to recognize it?
thanks in advance.

I have a Sony Vaio laptop and vista operating system. But for some unknown reason even when i have no USB connected to my laptop i keep getting a notification saying "USB not recognized" which flashes up and then disappears only to reappear again about 30 seconds later. I have turned off the error sounds because of how annoying it was getting but now my computer stutters and slows each time i get the message. I recently sent my laptop off to be fixed by Sony only to be sent back to me as they said i had no problem. Also when i try and connect things to my USB ports like a mouse or and iphone neither is picked up by the laptop. The iphone starts charging but will not connect to itunes as it should do.

This is THE most annoying problem. Please help, i am new to this forum.

Thanks in advance!

I can't remember if I posted this. I posted it on microsoft.com. But I don't think I posted it here. I can't get VB 6 to recognize the SP6 when I run that exe file. I no longer get a "SP 6" on the splash screen or help|about.

Someone on microsoft's forum said they had no trouble doing this with xp home sp2 as I have tried and not succeeded.

I'm running WinXP home w/SP3. When I start IE8 and hit Help - About Internet Explorer, it says that it is IE8. Yet the OK and the System Info buttons do not work - nothing happens when you click on them. I find this curious. Also, when accessing Youtube, it tells me that I'm running IE7. Who is right? Is IE8 installed but not working properly? Any suggestions on what to do about it?

My first post as a new member though I have surfed the site many times in the past and found it very helpful.

The problem I am having today is on a family members system. Up until a couple of days ago the DVD and CD/RW were working fine and then for some reason they quit. I have run into this in the past and the culprit was a virus, but I cannot find a virus on this system. I have run a complete scan with Norton (what a resource hog and this will go as soon as I resolve this issue), as well as removed any spyware found by Windows Defender as well as adaware, which was very few.

In the device manager there are exclamation marks on both drives. I have unplugged the drives from the motherboard, removed the drivers and rebooted the system and plugged the ribbon back into the board where it once again recognized the drives, loaded the drivers where I then find myself right back where I started from.

When it reloads the drivers I get a message stating that "A problem occurred during hardware installation. Your hardware may not work properly". If I right click on the device's it says "Windows successfully loaded the device drivers for this hardware, but cannot find the hardware device".

I am stumped at this point. Any help would be greatly appreciated

For some reason my 60G drive is only being seen as a 8G drive.

During installation of a fresh copy of XP SP2 the largest that I can partition I can create is 8G.

I have run the HD Diagnostics that is in the BIOS and everything passes. I have also booted off of a Linux Live cd and Linux lets me create a 60G NTFS partition but when I go to reinstall XP again it will only see 8G. I have updated the BIOS on the laptop tried writing zero's to the entire drive as well. If I install XP on the 8G partition I look in Disk management and it only sees 8G with no unused space available to create another partition.

My guess is that the drive is failing but it seems odd that Linux would see 60G and let me write zero's to the entire drive without errors.

If anyone has any ideas on this please let me know. I would rather not buy another drive if I don't have to.

The learning curve is steep and I'm out of ideas. I cloned the 30gb Ultra ATA drive from my Dell Inspiron 600M to a Seagate Momentus 5400 Ultra ATA 160gb with an Apricorn Update Kit - a first for me. That seemed to go well, but the new drive is not recognized in the BIOS -"Primary hard disk drive 0 not found." The drive is enabled.

I'm confused about the jumper setting since on the drive it shows no jumpers if you want it to be the Master, and that's how my original drive is set. but the Seagate site says it should be in the Cable position, 7&8. I don't have a jumper to play with (but read that I might find one on a CD drive). Have read conflicting notes in here but think that that would cause the drive not to be recognize? Yes?

Tried to use the SeaTools diagnostics from Seagate, but no luck.

When I put the Seagate drive in, I don't feel it "seat" like the old drive and wonder if for some reason it just isn't connected properly??

No problems getting my old drive back in and running (no problems with it).

There should be no compatibility problem as best I could tell.

I'm hoping it is just a jumper issue but before I go tearing more things apart I thought I'd get some feedback.

Is the drive not recognized anywhere OR just in My Computer? Please check Device Manager and the BIOS to see if it shows up there. If not then remove the drive from the laptop and then reinsert it and check those places again.
