• My acer aspire laptop suddenly stopped working, just a blank screen

  - by mazda

  My acer aspire laptop suddenly stopped working while it was connected to my nokia mobile modem through usb. It stopped with power swich staying on and no response to clicking off, no irregular sound, nothing but just a blank screen. I disconnected the power and battery quickly but power switch did not respond at all and even the power indicator didn't turn on again. the display was also gone after disconecting the power and removing battery. It has no response or any sign of power while both battery and power supply are working. What do you think? A completely dead mainboard? Does the MB has any safty board or fuse that could be replaced? Any suggestion will be appreciated, Thank you.

• Alignment requirements: converting basic disk to dynamic disk in order to set up software RAID?

  - by 0xC0000022L

  On Windows 7 x64 Professional I am struggling to convert a basic disk to a dynamic one. Under Disk Management in the MMC the conversion is supposed to be initiated automatically, but it doesn't. My guess: because of using third-party partitioning tools there isn't enough space in front and after the partitions (system-reserved/boot + system volume) to store the required meta-data. When demoting a dynamic disk to a basic disk manually, I noticed that some space seems to be required before and after the partitions. What are the exact alignment requirements that allow the on-board tools in Windows to do the conversion?

• How do i have 4GB of video memory with a 1GB video card?

  - by Tomas Spc Yaczik

  I ran the direct X diagnostic tool to take a look at my graphics capabilities and its telling me that the approximate video memory is clocked in at 4096MB. That doesn't make any sense, how is that possible? The only things that i can think of were that DirectX was inaccurate so i looked at the graphics statistics of my computer on CPU-Z which was included with the motherboard and that's telling me i have "negative" 1988MB. Not only is that not 4096MB, but its giving me a negative number and i know for a fact that you can't have a negative amount of memory???!!! The only things i can think of that would be amplifying my video memory output is the PCIe 3.0 bus, or that the motherboard is somehow including the on board video chip set with the video card which only then is only 2GB of video memory, which still has to be being amplified by something. Any suggestions?

• Again WPA Connection problem even after changed to latest version ..please help

  - by Renjith G

  I am using hostapd, wireless tools with madwifi for my wireless ap in my board. The WEP, WPA-PSK connections and communications between my board with linux and my desktop PC, Windows XP SP2 (with Olitec USB wireless) are fine. But when I configured the WPA type, the connection seems established but shows the status "TKIP - Key Absent" in the security dialog box. Anyone faced this problem?

• System shuts down immediately after few sconds

  - by Anil

  I have a computer with following specification and was working fine after re-installing the system and refitting sink fan unit. Recently it shuts down automatically after a few seconds. I checked PSU by shorting pin no.s 13 & 14 as well as 14 & 15. It worked well means the PSU fan moves. But I never checked the voltages at different wires. I refitted the heat sink fan by applying thermal paste. but it behaved the same. Again I refitted the Heat Sink Fan, then it worked for 2 minutes and again shut down. Now it shuts down immediately after switching on. Mother board : M26GTM-3VP CPU : AMD athlon PSU : 450 watt Can anyone help?

• Wake network adapter from deep sleep mode

  - by BeatMe

  I recently buyed a new Mainboard (Asrock ALiveXFire) and got some trouble with the network adapter. After switching my Windows 7 x64 in energey saving mode and returning from it, my network adapter couldn't be found. After some googling I found out, that apparently my network adapter has been put in a deep sleep mode and didn't reactivate. Their solution was to switch the PC off, take out the RAM and the CMOS battery for some time. After that, the adapter should be powered on again, but that didn't happen for me. I waited several hours before turning my PC on again, but that didn't help. Formatting and reinstalling didn't help either. The network adapter is not found in the hardware manager and reinstalling the drivers didn't help. I have the newest BIOS installed on the mainboard. I literally don't know what to try next. I'm thinking of returning my board, but I would like to avoid the hassle.

• Are Motherboards for the Acer Aspire One AOA150 Netbook Compatible with the AOA110?

  - by Mindstormscreator

  I have an Acer Aspire One ZG5 AOA110-1588 netbook, and the motherboard doesn't have a port for a SATA 2.5 inch hard drive; it only supports this slow 8GB SSD type drive. Through research I've discovered that the AOA150 motherboards do have a SATA slot, and the bottom plate of these laptops have an appropriate protrusion for the drive to fit in (for example, compare this to this). The AOA110 and AOA150 models are very similar in appearance and specs. I've even seen tutorials that involve soldering a SATA connector onto the AOA110's motherboard, essentially creating an AOA150 motherboard (right?) So, could I just swap out the motherboard in my netbook with the MBS0506001? (I'd post another link to the actual board but can't because of the spam prevention...) I assume I would also need to purchase and replace the bottom cover with a larger one and possibly get a hard drive caddy as well...? Thanks!

• Should I use SSD Caching on non bootable HD?

  - by Onema

  I have an asus 9p79x pro which allows me to do SSD Caching. I have a 256 GB SSD drive that I use an my primary boot drive, and I have a 1 TB disk where I put most of my games, music, videos, dowloads, pictures, etc. I also have an extra 64 GB SSD Drive that I'm currently not using. I thought it would be a good idea to use it as my 1 TB disk cache and improve the load time of games and programs that are installed on the 1 TB disk; but will this work correctly? It seems from all that I have read online about this board that it is used to cache a boot drive. Any thoughts? Thank you

• Dedicated GPU in Dell PowerEdge C1100

  - by Eli Gundry

  We recently purchased a Dell PowerEdge C1100 off lease with the initention of using it for graphics processing. We installed an AMD HD 7000 series GPU in it that runs off of board power and it sends video to the display. That said, the video is very choppy, leading us to belive that the onboard video is doing all the processing and sending it to the card. Is there any way to either disable the VGA on this server or tell the OS to only use the dedicated card. More info: The server is running REHL 6.4 The graphics running the proprietary AMD drivers The video card only works in OS and does not show the BIOS on boot (we know that it's impossible to change this) Any ideas, guys? Update We are now thinking that the GPU is doing the graphics processing, but not working at the full speed of the PCI bus. Which is odd, because it is an x16 slot, but probably optimized to use a RAID card (if that makes any sense). Is there any way to remedy the choppy graphics on this server?

• Bluetooth not seeing mouse (Fedora)

  - by Chris

  I have a Lenovo S10 'netbook' that I've installed Fedora 17 ("LXDE spin") on. So far pretty much everything works great, except, the on-board Bluetooth. lsusb shows the controller present (0a5c:2101 Broadcom Corp. Bluetooth Controller), hcitool dev shows hci0 present, but when I put my mouse ("Lenovo Bluetooth Laser Mouse," which works perfectly paired with a MacBook Pro, MacBook Air, Mac mini, and Lenovo SL500 (with a USB dongle; running Windows 7)) into pairing mode and run hcitool scan (reports "Scanning ..." and, without further information or error message, returns to the shell prompt), blueman-manager, or bluetooth-wizard (from the gnome-bluetooth package) and try to detect the mouse, I get nothing... Frustrating! Thanks anyone who can point me in the right direction!

• Roundcube can't connect to PostgreSQL database

  - by kenny.r

  I'm trying to install Roundcube on a CentOS 5.5 server, with a PostgreSQL 8.1.22 database. The first page of the installer script, that checks for the presence of php libraries and such, gives me green OKs across the board. I even went out of my way to install the optional ones. Page two generates me two configuration files (main.inc.php and db.inc.php) which I put into place. Page three is where things go wrong: Check DB config DSN (write): NOT OK(MDB2 Error: connect failed) Make sure that the configured database exists and that the user has write privileges DSN: pgsql://roundcube:password@localhost/roundcubemail The info you see there (user roundcube, password password, server localhost and database roundcubemail) is all correct. The database roundcubemail belongs to the user roundcube and it has write permissions. I have no clue why it can't connect to that database. I'm managing it with phpPgAdmin, which is running on the very same Apache, on the same server!

• Trust Bluetooth 4.0 and Bluetooth Headset

  - by Seregwethrin

  Firstly, I'm writing this after 5 hours of nonstop struggle to make it work, so I searched into the deepest websites from Google, and tried many things. I have Trust Bluetooth 4.0 USB adapter (link) Samsung HM1500 Bluetooth Headset Windows 7 64-bit Desktop PC Facts Nothing wrong with the headset. (it works, tested on a phone and a laptop. Problem is all about bluetooth dongle and its driver.) Trust BT adapter can send and receive files even without any driver. I can pair successfully without any driver too. In Headset's Properties, Services tab, Handsfree and Headset services are checked. Problem When I pair with my BT headset, I cannot see it as a sound playback device. Also when I double-click the headset device icon in Bluetooth Devices, in laptop: it opens a connection window where I can connect and disconnect to that device - perfect! in desktop: it opens the properties window, even though Handsfree and Headset services are checked (I check them explicitly, in laptop they came as already checked) - Problem! Unsuccessful driver installations The driver on the Trust's website says "Error 1606 Could not access Network Location" on start, so it doesn't get installed. The driver on Broadcom (link) is being closed with Windows's that classic "has stopped working" error on validation step, so it doesn't get installed too. (Those tests made more than once) Successful installation In the Win64 folder of Trust's driver from their website, if I install through "BTW.msi", it doesn't give me Error 1606 and it gets installed. Then the problem: When I try to start bluetooth from start menu (or it gets started at Windows startup), an error popup says: "BtBalloon.dll is missing..." so it doesn't start. I found BBalloon.dll in the driver folder, I renamed it to BtBalloon.dll, moved into Windows/system32 and Windows/SysWOW64 folders, and it seems working. Or maybe it gets closed behind the scenes. The bluetooth icon is there with or without this driver since Windows has it. Bluetooth Peripheral Device First it didn't get installed from Windows Update. After, I showed the driver folder path in Device Manager and pressed "Explore in this location". Surprisingly, it's being found as "Handsfree" driver. Now even I uninstall the drivers, it still can see the Handsfree. But still, no playback device. Any ideas to guide me? I'm out of ideas.

• Computer has video artifacts after been exposed to rain

  - by Sadie

  My desktop now displays video artifacts after been exposed to rain. Only a very small amount of moisture went inside the case. The only place I noticed any water was on the CPU socket. I used a hair dryer and paper towels to wick any remaining moisture. When I boot the PC it loads it the OS, but there are large numbers of video artifacts. The artifacts appear symmetric if that helps. I am wondering what components I need to replace. I'd like to salvage what I can. My setup: AMD Athlon x3, Asus main board (AM2 socket), nVidia GT 430 PCIe, 8gb (4gb x2) DDR3

• Windows 8.1 unable to play Music or the Audio from videos through Optical Out

  - by Zion Fox

  I am having an issue with my audio output, where any music file, and the audio side of videos are not being played through my optical audio output. I am running a Realtek HD Audio device built on Revision 1.0 on a GA-P55A-UD6 Gigabyte Board, which runs through it's optical output to an Astro A40 Mixamp, which does some upscaling before sending it to the headset. Now, notification sounds, and sounds/videos/music played through the browser or programs like Skype or games are working fine. This seems to specifically effect Foobar2000 and Media Player Classic. I have updated these two programs to their latest revisions, in addition to the soundcard drivers to no avail, and searching the error code thrown by Foobar2000: Unrecoverable playback error: The parameter is incorrect. (0x80070057) through Google returns not very helpful results, other than the one potentially mentioning DRM. This issue I am having a very hard time resolving, and am wondering if anyone here has experienced similar issues after updating.

• Creative software leftovers - ASIO error message

  - by Tony Patriarche

  I temporarily installed an old Creative Audigy 2 soundboard on my Vista x64 Home Premium computer. Bad idea! I uninstalled the board & all software visible on the control panel. Now, with one particular app. (Sibelius) I keep getting a start-up message "CTASIO Warning: Creative ASIO: there are no Creative audio products installed on the system that support ASIO". I offer this as a candidate for "Most useless message", but that's beside the point. I used a commercial registry cleaner (PC-Tools Registry Mechanic) and then edited the registry looking for "creative", "audigy" and "ASIO". After removing everything I could find, I still get the message. Any suggestions?

• HTTP Non-persistent connection and objects splitting

  - by Fabio Carello

  I hope this is the right board for my question about HTTP protocol with non-persistent connections. Suppose a single request for a html object that requires to be split in two different HTML response messages. My question is quite simple: do the connection will be closed after the first packet dispatch and then the other one will be sent on a new connection? I can't figure out if the non-persistent connection is applied at "single object level" (does't care if on multiples messages) or for every single message. Thanks for your answers!

• Windows 7 Service Pack 1 Install Failing

  - by Cu Jimmy

  I am having real trouble updating one of my machines to Win7 Service Pack 1. Its an Asus P5K board with an X9650 Quad Core Extreme chip, which is a less common type of chip. Was wondering if anyone has had issues with this kind of kit or if it may just be the motherboard is a little gone. The error message I get back from Microsoft Update is WindowsUpdate_80091007 and WindowsUpdate_dt000 which are fairly generic errors. Tried installing with the sp1 file based installer and got nowhere. The actual installer crashes with an SP Installer has crashed Its a fresh install on a fully scrubbed drive (an Intel 120GB SSD).

• How low-power can a home server get?

  - by Halik

  I've got quite simple question actually. How green, low-power and efficient x86 home server can I build using consumer parts with rather constrained budget. After looking through some Google hits I've found out that system based on dual-core atom, some modest mITX board (gigabit lan, integrated audio and gfx etc), one RAM module and one 'green' WD HDD, powered by picoITX PSU uses about 30W at idle up to 40 at load. Can you get lower (or how much lower) then that? Maybe some VIA nano chips, or single core atom? My home server would take care of some back-upping mixed with little ftp/http traffic.

• Freebsd or Linux? as BGP router over 100mbps

  - by Yucong Sun

  I am building a server to act as a BGP border router for my 100mbps uplink in ISP. I needs these feature: 1) Dual stack BGP peering/routing (at least 100Mbps, maybe more). 2) Potential full internet BGP feed. 3) Some basic ACL functionality. The hardware is L3426/8G ram. NIC will be on-board dual port Broadcom 5716. I've worked with Linux extensively before and it seems to be able to handle 100mbps, but I heard FreeBSD is faster on networking stuff. Which one should I use? And do we have some performance benchmark numbers out there? Cheers.

• Super-silent (mid tower) case and fan combo

  - by Dennis G.

  I want to build a HTPC for music/video/blu-ray playback (no gaming). I don't need an expensive HTPC case but just want to go with a standard medium tower case. However, I want it to be super silent so it doesn't make any annoying fan/disk noises when I watch movies. Ideally, it shouldn't make any noticeable noise at all. I understand that choosing a board, CPU and graphic card that run cool and don't consume a lot of power is important for designing a quiet machine, and I think I got that covered. However, there are so many choices in regards to cases, fans and power supplies that it's hard to get started. What are your recommendations for a case/fan (cpu+case)/power supply combination that run absolutely silent and can cool a standard Intel system with a low-power (possibly passively cooled) graphic card? I'm usually a fan of Antec cases, would an Antec Mini P180 be a good starting point? If so, which case fans, CPU fan and power supply would you recommend?

• Considering building a new system; but undecided about chassis

  - by J.C. Bengtson

  I'm considering a new system build, and was thinking that this particular motherboard has features I need and like: http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=667651&pagenumber=1&RSort=1&csid=ITD&recordsPerPage=5&body=REVIEWS#CustomerReviewsBlock .. but am unsure which model chassis to pair it with. I'd strongly prefer something from Cooler Master, as I'm a fan of their products, but am having a hard time deciding, and also don't want to get into some odd situation where the board doesn't properly fit. I plan on having two optical drives (5.25"), two internal HDs (3.5"), and will likely go with an SLI setup of 2 or possibly even 3 cards, so I'd need a chassis that is roomy enough to accomodate all of that, as well as the motherboard itself. Based on the stock available at that same site, do you all have any suggestions? The larger, the better, as I hate having components crammed together. Your help is most appreciated!

• Linux Bluetooth [closed]

  - by Chris

  Not sure if this is the proper forum; please forgive me if it's not... I have a Lenovo S10 'netbook' that I've installed Fedora 17 ("LXDE spin") on. So far pretty much everything works great, except, the on-board Bluetooth. lsusb shows the controller present (0a5c:2101 Broadcom Corp. Bluetooth Controller), hcitool dev shows hci0 present, but when I put my mouse ("Lenovo Bluetooth Laser Mouse," which works perfectly paired with a MacBook Pro, MacBook Air, Mac mini, and Lenovo SL500 (with a USB dongle; running Windows 7)) into pairing mode and run either hcitool scan (reports "Scanning ..." and, without further information or error message, returns to the shell prompt) or bluetooth-wizard (from the gnome-bluetooth package) and try to detect the mouse, I get nothing... Frustrating! Thanks anyone who can point me in the right direction!

• How do you confirm network adapter is gigabit capable?

  - by StrandedPirate

  Upgrading my network to gigabit speeds and don't know how to determine if the NIC in one of the systems is capable of gigabit speed. The documentation from the manufacturer states this: Network adapter 10/100/1000 Ethernet LAN on system board However when I go to the properties of the NIC under Speed & Duplex my only options are: 10 Mb Full 10 Mb Half 100 Mb Full 100 Mb Half Auto Is there a command line I can run that will give me more detail about the NIC? Windows 7 x64 OS New Info: The new switch I just bought has a light to indicate 1000Mbps. I can tell from the light that this NIC is indeed negotiating at 1000Mbps but I'd still like to know how to determine this from the console in windows.
