4pin Of A 20+4 Pin Mobo Power Was Not Plugged In
Jul 24, 2012
My system randomly turns off. no blue screen. No crash dump. no windows shutdown screen. This isnt really about the shutdowns.
1 - What happens when the 4pin connector of a 20+4 pin mobo power plug is disconnected
2 - Does the 4pin connector give more stability to a pcie2.0 x16 Graphics Card?
3 - What damage could have been done?
Ive swapped the graphics card out with a Power Color HD4850. The shutoffs happened with both. I have four ram chips. i took out 2 and it still shutoff. Im now trying the other two.

can I use a 6-pin graphic card when I only have 4 pins on my motherboard? I want to upgrade to a gtx 550 ti, and my motherboard is Asus P5KPL AM-SE. Can I use this card?

My laptop wouldn't boot yesterday, the fan came on and the 'on' led came one, it beeped when I plugged in the charger but nothing on the screen and no post beeps etc. I let the battery drain fully, plugged it back in once it powered off and it booted fine. I shut it down last night and it did the same today on boot up, nothing. Again, discharging the battery fully brought it back.

I have a laptop with Win 7 HP 32bit SP1, which doesnt boot at all, if the power cord (AC Adapter/Battery charger) is plugged in. Further if power cord is plugged in after booting, the system hangs / shuts down. It runs fine on safe mode. I believe it is a driver updation problem but not sure. I have updated all drivers given in Toshiba download site.

I've done a lot of searches using variations of the above title and came up empty or just plain missed the answer.I'd like to know, if it is not asking too much, the following points:
1. What exactly is the function of Link State Power Management in the Power Options Advanced Settings, PCI Express?
2. What are the implications of using the options available:
a) Off.
b) Maximum power savings.
c) Moderate power savings.
d) Which option is the best selection for my Dell laptop.

I use my PC for audio production and I have a few external controller devices that are USB powered, for example a midi keyboard. I recently had to build PC due to a theft....long story short after building the new PC I've noticed that my USB buses have continual power to these external devices after I've powered down the PC. My old windows 7 PC did not do this. Is there a setting I can change to shut off power to the USB buses when I power off the PC? Or is this a hardware issue?

i've tried to set the option for pressing the power button to 'Do Nothing' so no body can shut the computer, and yet it shuts down by pressing the button, so why is that and how can i work this out?

I'm looking to upgrade my CPU and Motherboard from what I currently have.I recently purchased a GeForce GTX 680 but I am seeing minimal improvement from my previous GeForce GTX 480, and have come to the conclusion its my CPU holding me back.
Current specs -
OS - Windows 7 Home
CPU - Intel i7 930 @ 2.80GHz
Motherboard - Gigabyte X58A-UD5
I have been told in the past I cannot replace one and not the other due to my CPU/Motherboard being 1366 pin which is no longer in make.

I just got a new mobo and CPU and was wondering if I will need to reinstall windows with this. I have read different things, some said you can just repair others say complete reinstall.

low computer knowledge person here and I have recently come into a problem after replacing my mobo/processor/gpu from my old computer. After hooking up the computer and booting it up, it hits the mobo screen then quickly goes into the black screen that says that windows 7 can not be started and gives me the two choices of system startup restore and start windows normally.
Starting windows normally unfortunately returns me to the black screen and so I tried out the restore but to no avail it was unable to fix my problem.Also, I was stupid enough to not transfer any files from my hard drive off to a backup.
My two questions are if it's possible for me to put my hard drive in a friends computer and take the files off there and also if there is any way to fix my hard drive after changing motherboards.

I just built my PC (first one, sounded like a good idea at the time) and was told that getting the latest drivers would "fix" this issue. Problem is, I haven't had a PC or really been on the net since 2001, (don't laugh) so.....I don't know how to get the "right" ones. I realize that i've built something waaaayyy over my head/experience level, so now I just want to learn all that I can.

Over the past 2 years my PC has been afflicted with random power off/power on/reboot events.It will go for months without these and then have multiples of the events in a day. (I had 8 of them 3 days ago.)I assume I have a hardware problem, but nothing has been found and I'm grasping at straws.The time between power off and power on is several seconds.I had assumed this rules out a software cause, but maybe I'm wrong. I know Windows can schedule a power off, but can it tell BIOS (or something) to power back on in a few seconds?I know blaming the power supply is a much more simple explanation, but then I'm left with explaining the intermittent nature of the failure.

OEM pc MOBO died, replaced MOBO, windows having trouble booting (expected). attempting repair with no results but FAIL. I am noobish, so I ask, what can I use to help the repair process? PS: I upgraded my OS out of the box From win 7 home premium OEM install, to Windows 7 Ultimate x64 via disk. I also have win 7 premium (full) on disk from another PC i installed it too. I would do a clean install, but I can't lose any of my photos and data.

I have an asrock 775dual-VSTA and I recently upgraded to Windows 7 Ultimate, 32bit.
Things seemed fine, but I realized my USB was performing very slowly.
For example, it takes hours and hours just to upload a few albums to my iPod.
I presume it's a motherboard driver problem. Does anyone know of a fix for this? I dont see any Windows 7 drivers from Asrock for this Mobo.
Im *really* hoping I dont have to buy a new one.
Here are some screenshots from my Device Manager. As you can see, USB seems to be fine, but there are those unknown devices that I have no idea what they are. As far as I can tell, everything is working fine except the USB speed so I presume these unknown devices are related?

If device manager is happy that Windows 7 has managed to find drivers for everything automatically, would the team recommend leaving well alone or going for the mobo vendors drivers?
(I ask because all was well until I installed the Asus Windows 7 drivers for my P5Q...)

I have an issue with my system.
- ASUS M4N68T-M LE V2 MoBo
- Processor is AMD phenom II X4 965 Black Edition.
- One Stick of 2Gb memory DDR 3
- ATI Radeon 6870 Sapphire.
If I restart my system (and this happens like out of 100 restarts 97 times) the system would be on the black post screen and say that the CPU is not compatible with my mobo. Then in order to resolve this I have to got to BIOs and turn on all the cpu cores and the unleashing mode under CPU and restart. Then it would reflect that all the **4 cores are active** and then it would work fine. But why does this happen after every restart. I thought it was CMOS battery but the date and time and other BIOS settings are fine.

I know that since during a windows installation, certain libraries are installed specifically for certain types of chipsets/cpu's and that an abrupt hardware change can cause failures. I read on an article somewhere that you can migrate windows without hardware errors if you manage to get windows to operate on a politically correct mode similar safe mode to boot up with minimal functionality before installing the appropriate drivers for the new board.

I bought a scythe fan for my case to go on the side, i've tried plugging the 3 pin connector into the PWR_FAN(3 pin) and CHASIS_FAN(4 pin), it gets detected in the bios and in speedfan, and various other software to monitor the fans.
Its running at 3,000 RPM which is way to loud for me, i've tried ASUS AI suite, amd overdrive, speedfan ect to try and turn down the RPM but none of them effect it, its going at 100% non stop and wont slow down no matter what, and even in the bios when i selected 'silent' mode it did not budge in speed at all.
Mobo: ASUS M4A87TD EVO AM3 AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
Fan: Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Case Fan
Anything i can do to make this software or bios adjust the fan to the correct speeds? If i bought a hardware fan speed controller would that work? I was looking at something simple like this: Newegg.com - Sunbeam PL-RS-PCI Rheosmart PCI 20W Fan Controller
But i'd rather not buy if my Mobo or some software can adjust the speed for me.

Am planning a new build and the Asus P8Z77-V board is cheaper by $40 than the Asus P8Z77-V Pro but has 8 phase power as opposed to the Pro with 12 phase power.Now I have done a quick Google and there are refs to this but could someone put it in plain / basic wording as there are some refs to CPU power supply, vdroop, and other tech stuff that I don't really understand??I intend running an i5 3570K and have try at over clocking - if that has any relevance for what my query is about.

I have the above mobo, just installed windows 7 64bit. Everything else is fine but I cannot get the sound to work even though when I test or play music I see the bar rise and fall. I have exhausted everything I know to do. I did see the CM6501 thread here but after trying the drivers, it still does not work and when I click the CM6501 icon, it freezes the PC and I have to reboot.
Any ideas?
CM6501 integrated USB soundcard.

In a few days I will be upgrading from my AMD 965 Black and Gigabyte GA-870A-UD3 to an Intel i5 2500k and GIGABYTE GA-Z68XP-UD4. I was curious as to what you all thought I could do to minimize effort and problems restoring my system settings, programs, and data files after a clean install of Windows 7.I currently have 3 HDDs; A 640GB for my OS (C: ), a 1TB for Programs and User files (D: ) (Pics, Docs, DVDs, etc.), and a 500GB (E: ) for Win7 backups. I also have a NAS (\NAS) with 500GB. At this point I have good User File backups on E: and am now creating IFW drive images of C: and D: onto the NAS. I have also generated reports from SIW (Hardware, Software, and Network) and Win7's System Settings from the Advanced Tools control panel.

Today I built my new rig (specs below) and I kept the hard drive off my old gateway to save some coin. After I installed all the new hardware I turned it on and the ASrock screen popped up and prompted me to choose instant flash, select boot order, enter BIOS, and switch screen. When windows 7 attempts to load it stops while the dots are floating towards the center. The windows repair tool didn't help what-so-ever (go figure >.> ) and the PC won't/can't run in safe mode. I updated the BIOS from the ASrock website but that didn't help. I've tried all of the options provided and none worked. I don't want to format my drive and lose my data but I will if I must because I may have access to a new copy of Windows 7.
Corsair cx500
WD green 1TB
Sapphire 7950 3gb
Cooler master elite 430 mid case
ASrock 770iCafe ATX motherboard
AMD FX 6100
Basic RAM (6GB) (x2 2GB, x2 1GB)

Just installed Windows 7
Do I insert the CD that came with my PC (which included the original ASUS driver) & install that driver, THEN go to the ASUS site and update the newest driver?
OR is there another/better way.
Oh - did a clean install of win 7 and I do see a Windows.old folder - if this is of any help.

Computer will not sleep after installing a new mobo. It starts initiating sleep mode and the fans and such shut off and the screen goes blank but after a second the fans and everything come back on but the screen stays blank and the only way to get it out of this state is to hold the power button until it shuts off. I checked the BIOS and did not see anything related to sleep mode. Where would a setting for this be located?

I've replaced much of my PC's hardware, mobo/CPU/memory and I want the existing Windows 7 HHD to boot. What's the method? I can't even figure how to install the new mobo drivers without a booted OS.

My motherboard manual says i have a "PCI express" video card slot. but it doesn't say if 1.0 or 2.0 or 3.0. I'm assuming it's 1.0 because the motherboard is a bit old and the video card as well(Nvidia geforce 7300 se/7200 gs) If i'm right and it's a PCI-e 1.0 motherboard, what video card can be compatible with it? 1.0 or 2.0 or 3.0? I want to buy a new video card.
