Windows 7 64 Not Recognizing All RAM In Laptop
Jul 23, 2011
I've been searching the forums for a solution to this and I don't know what to do: [code] so according to the MOBO spec, I could have 8Gb ram.I bought 2x 4GB Corsair memory.I have made sure that the memory chips are seated correctly BIOS detects that there is 8GB of RAM installed here is the system report on the RAM: Installed Physical Memory (RAM)8.00 GB Total Physical Memory3.93 GB Available Physical Memory2.22 GB basically my system is detecting but not using one of the RAM chips.I don't have a setting in BIOS to map memory.I can't get to the motherboard to adjust any jumper/ voltage settings CPU-Z shows both chips installed and working.I am running windows 64bit been into MSCONFIG and maximum memory is unchecked and this is where all my efforts have now run out. so I don't get it. 8Gb installed, 4Gb available?

I'm new to this site so hopefully i don't do anything wrong!! I consider myself fairly smart with computers but my laptop has gone beyond my brain At first it would just reboot itself after being on it for a little bit, I tried downloading an antivirus (avast) and it all went downhill!! Now it doesn't even recognize the windows 7, gives me a black screen telling me error and to put in disc, which I've never had one, and says: FILE CI.DLL STATUS:0XC00000E9 I cannot get it to go any farther than there,is there anyone that might be able to help?

I have a new laptop, which was set up for me in the shop. Everything was working perfectly. Now however, my PC is not recognising the printer. I have previously been able to print from this laptop using the same cable, printer and USB port.
When I try to 'troubleshoot' this problem, I get a message that the printer driver is not installed. I thought Windows 7 automatically installed devices when connected via USB?
I have double checked the cable with another laptop and all is fine. I have double checked both USB ports with other devices and all is fine.

I tried to run Mem86 and Windows Memory Diagnostic, but the BIOS doesn't allow booting from a USB drive. Also, Windows 7 doesn't seem to recognize the .iso file on the DVD even when I turned off "boot from hard drive" to force it to boot from the DVD drive.

I am running Win 7 on a Intel Core I7 920 processor. My motherboard is a Gigabyte EX58-UD3R FE motherboard. My RAM is (4) G Skill F3-16000CL9-2GBRH 2G sticks of DDR3 RAM. It says the type is PC3-10700H. When I check my system settings in windows, it says I have 8 GB installed but only 6 GB usuable. Is there any way to make it so that all of it is usable

i decided to upgrade my laptop from 3gb ddr3 of ram to 8 gb ddr3 , now i faced an odd problem where i got to realize that despite windows recognizing all 8 gbs of ram in system information (msinfo32) under "Installed Physical Memory" i realized that both system information and task manager shows "Total Physical Memory" to be 2.93 gb , i searched the forum throughly up till i came across this thread : Memory - Set Maximum Amount Used by Windows 7 now i got to realize that 32 bit windows can only handle 4gb of ram . now trying to sort my options i have a few questions i need to be adressed :
1 - is it smooth to upgrade from 32bit to 64bit of windows , i have heaps of programs installed over years that i cant risk to lose nor have the time to reinstall if i took the fresh installation option :/ if possible then how ? any specific tool or windows version ?
2 - any known porting , utilities or hacks that were made to make 32bit os recognize all 8gb ram ?
3 - if non of the above were valid , if i am to work with only 4 gb , why does my system read only 2.93 gb of which ? i can notice it sums up all spare 5 gb as "Hardware Reserved" . i investigated to see if the extra 1 gb is reserved by graphics card but only to find that my graphics card is only up to 750 mb of shared memory and those already are shared from "Total Physical Memory" and not hardware reserve , why i have access to only 3 of the 4 gbs of rams i'm allowed ?

I've recently unistalled my display drivers (because I was going to update them), and after the reboot, my USB devices (keyboard/mouse) will not work at the Windows logon screen. I've been reading this is a known issue.
Here is where my problem is, I can't do a system restore because I don't have it setup, and I really won't/can't format. (stupidly only have 1 partition with lots of valuable data on it)
I'm really just interested in manually installing the USB controller device that my display drivers somehow uninstalled. (I think it's related to the chipset).
I have access to the cmd prompt in a weird repair mode that I've been able to access, that does have keyboard and mouse support. So I'm just interested in getting Windows to recognize the keyboard/mouse at the Login screen so I can actually access windows.
EDIT: The USB mouse/keyboard will work for BIOS, but the second the windows loading screen loads, the sensor for my mouse and the light on my keyboard turn off, and is not recognized until I go back pre-windows load. If I can just get past the logon screen, windows would do it's "new hardware recognized" thing. But I am stuck at the logon screen.
EDIT2: I'm running a AMD 785G chipset. I uninstalled Catalyst 12.3 to upgrade to the latest. on an AMD HD6950.

I am on the administrator account and have full rights, but can't delete ANY files. My laptop was working fine and then just crashed one day (For 6 years). Now I can log on and access all accounts and all files but cannot delete files or connect to the internet. I have read through and tried suggestions from other posts and nothing is working.

I am having quite some trouble to install windows 7 on my new SSD drive. When I reboot without the old HDD the windows cd doesn't start up. So I tried to run the CD while under windows on the old HDD, which did work, but now I only have 8gig install on the SSD and its only a boot drive not a system one. Could it be that my motherboard is to old? I did have some issues to run the SSD alone, bios didn't recognise it quite often.
CPU - Core Duo E6500
Motherboard - Asus P5VD2-VM
RAM - 2 gig
old HDD - Samsung IDE 250 gig ( about 10y old )
new HDD - SSD Onyx 32gig + Samsung 1T both SATA

I just installed Windows 7 build 7068. 64bit.I have an Asus P5WD2E-Premium mobo, and 5 Western Digital Hard drives of various sizes, all SATA.Windows recognizes only 2 of the drives, the c drive of course, and only 1 of two WD 400gig hds, which are identical.I know this may be a mobo issue, but, wasn't sure about Windows 7.

I've been running windows 7 pro 64 bit for just under a year now. Couple days ago the computer was on just sitting idle while i was around the house, then i noticed this message pop-up the windows firewall was not active and if i wanted to activate it, ever since then i have not been able to get the computer to recognize any sort of internet connection. Im on a wired connection to a wireless router (D-Link Xtreme-N Dual Band Gigbit), all other computers connected to the router work fine.there is a red cross in the little network icon in the taskbar. If I click that icon, it says �No connections available�If I click troubleshoot, it says �Problems found - There might be a problem with the driver for the local area connection adapter�If I look in the device manager, there IS an entry for �Network Adapters�, in fact there are two:
1) Realtek PCIe GBE family controller (which i recognize as the one from my motherboard Asus P7P55D-E Pro
2) WAN Miniport (PPPOE) [i have no idea where this comes from, but it has a yellow exclamation sign above it]
I have uninstalled 1) from the device manager and let windows re-install it on reboot, i tried installing drivers from the CD the mobo came with, i tried going on another computer and getting updated drivers from the Realtek website, none of them worked. if i try to uninstall the WAN miniport it does not disappear?If I look in BIOS the contorller is there and ON. Reboot, swapping ethernet cables, restarting router, scanning for viruses/malware with MSE, Webroot Complete, Malwarebytes finds nothing.If I rollback to an earlier restore point, it doesn�t help.The only thing i can remember that happened before the loss of connection was an update to TuneUp Utilities 2012 and Webroot Secure Anywhere 2012, both of which i've since uninstalled to see if it was one of those, but still nothing. Also completely disabling Windows Firewall doesn't help either.

Okay so I just install windows 7 32bit(clean install, not upgrade) and it's not recognizing my graphics card. All it says is "Standard VGA adapter".
I've tried installing drivers but it never works and I also tried uninstalling the standard vga adapter via device manager too but it reinstalled itself. Btw my graphics card is a ATI Radeon xpress 200.
Way back when windows 7 was in beta and i was a beta tester everything worked fine.

Earlier today I uninstalled a small utility off of the system disc ("C" ) and immediately my Windows 7 system would no longer recognize my other two internal HDD's. Upon a restart, Windows again sees that there are drives there but has issues. At first I thought none of the programs would run, but upon starting Starcraft 2, I watched the sc2.exe file in take manager tick up the megs resident in memory. It took about 7 minutes before reaching 100 megs in memory then the screen went black as if the game was about to start up. At this point I'm watching on my second monitor (w/ task manager) the program loaded a full 125megs before slowing down.
I was never able to get it to start up and it does this every time. The same is true for any other program installed on that drive. I can browse it just fine and everything is where it should be -- I've tried running the .exe from the directory itself with the same result.I'm no Guru, but I'm fairly good with computers and have never seen anything even remotely close to this. I don't know if the uninstall is related, but it seems likely as it was right as that finished.

After installing windows 7 and all drivers for my Samsung t220 screen and Nvdia GeForce 9800 GT, neither windows 7 nor Nvidia reconognize 1680x1050 resolution. Maximum resolution permitted is1280x1024, very deficient. Had no problem with XP and analog cable). I have tried powerstrip and created a personal driver with a 1680x1050 resolution, but with the same negative results. Buying "just" another screen is no option! Samsung doesn't provide specific drivers for windows 7.

I'm using the release candidate and whenever I plug in my Western Digital Passport USB external hard drive, I get nothing. It doesn't show up in device manager or in My Computer. The light on the harddrive comes on and the drive spins up, so I know it's working. Windows just won't recognize it.
