HP Mini Won't Recognize USB Devices - Keeps Freezing / Bad Shutdowns
Nov 7, 2012
There are several problems with HP Mini netbook. First among them is that programs keep freezing. It seems to start up normally, but shortly after you launch any program (even explorer or the control panel), it hangs. This means among other things that I can't get into Device Manager to look at things like drivers because I can't get there before the freeze sets in. When it happens I can still get to the toolbar and use the start menu and so on, but if I try to launch any other programs, nothing happens. Also I can't force the shutdown of the "hung" programs.
I figured this sounded like a Class A virus situation, so I tried to download some tools like AVG. The Freeze got me, using both IE and Chrome. I tried loading up my USB Thumbdrive (full of troubleshooting tools). The HP won't admit that it even exists, and the access light on the stick never blinks. An external USB HDD available, so I hooked it up. Again, not even rejected, just ignored. The HP will recognize an external DVD drive, but refuses to let me write anything to a black disc. In fact when I try the drive disappears altogether.

The BSOD errors started two weeks ago when I woke my computer from sleep mode. It BSOD before it got to the login screen. Unfortunately, I didn't catch what it said. Since then, it hasn't crashed on startup again and instead I get a video scheduler BSOD whenever I play a game or video. I've tried everything from updating,uninstalling, reinstalling drivers to running tests on RAM and harddrives. Nothing has worked and the tests have come back with no errors.
So, in a last effort to solve the problem, last night I restored my system to factory settings. Now it BSOD, freezes up and shuts down randomly while running programs that where once unaffected (internet explorer for example).
I'm really hoping it's a software problem and not hardware. The system is a notebook, so the only hardware I have easy access to is the hard drive, memory, and wireless card. Everything else is buried in the casing and would require ripping the system apart to access. I would like to avoid that at all costs.
The system has Windows 7 Home Premium 64bit OEM and the system is not even a year old. I've included the minidump and perfmon file.

I just recently installed windows 7 home premiuim on my windows vista home premieum computer. When my computer booted up with windows 7, everything worked perfectly and had no problems. I turned off my computer for the night and the next morning when i went to turn on my computer, none of my usb 2.0 devices (mouse, wireless adapter, etc.) worked. The only thing that does work is my keyboard and its a PS/2 keyboard.

I am running an HP Compaq 8510w with Windows 7 Enteprise. When I first got the laptop the USB ports didn't recognise devices when they were plugged in, and the laptop would just hang when shutting down (on the Windows Shutting Down screen), so I decided to reinstall the OS as there was a lot of unnecessary applications installed.
I've been using the laptop since the rebuild and all has been good, until the past week or so when the same two problems have materialised again - when I attach a PSP, or a printer via USB, they are not recognised. And when I shut the laptop down, it hangs on the Shutting Down screen.
What checks can I run to see what the cause of this might be? I've not really installed a load of software on here, and I can't think of anything specific that I may have done that would cause this...

Synopsis: PSU died, replaced PSU with different model, system boots to bios successfully but does not recognize any devices in SATA ports, nor do those devices appear to be getting power. Now can't even get to BIOS, entire PC flicks on and off repeatedly as soon as I turn the PSU on regardless of whether I hit the power button on the front of the computer.
System Specifications
Original PSU that died: SeaSonic M12II 750 SS-750AM 750w PSU
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz
GPUs: ASUS 670 non-top version, SLI (2x)
MOBO: ASRock Z77 extreme 6
RAM: Mushkin Enhanced Blackline 8GB (2 x 4GB) SDRAM DDR3 2133
Optical drive: Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive
SSD: SanDisk Extreme 240GB SATA 6.0 Gb-s 2.5-Inch (OS is installed here)
Storage drive: Western Digital Caviar Black 1 TB SATA III (This was not connected when power supply died)
Detailed explanation:About a week ago my PSU (Seasonic 750w) died randomly while the computer was left running in sleep . I RMA'd the dead seasonic. In the mean time I happened to come accross an extremely good deal on a new PSU, so I bought it (Thermaltake smart m850w PSU) to have a backup and to get my machine working again. I hooked up the new PSU to GPUs, CPU, fans, ATX power connector, and to all of the SATA devices, (the SSD, the HDD, and the Optical drive). I made sure to connect the data cables to the SATA devices in the same configuration they were in when working properly. The computer boots successfully to the ASROCK BIOS, all fans spinning. However, I get the error code "A6" on "dr debug" (the led display on the mobo). The manual says this means "SCSI detect". I have no idea what that means.
I was able to load the UEFI, and bios recognized all components except for any of the SATA devices--(SSD, the HDD, and optical drive not recognized). The RAM, GPUs, processor, and fans were detected. At this point I was stuck in BIOS because I couldn't boot off anything.I did not have the HDD connected when the PSU failed, but now the BIOS won't read that either. I don't think any of the SATA devices are actually receiving power. Again, the UEFI showed that there were no SATA devices connected to any port, when in reality they clearly were connected both by power and data cable. Then things get really strange. I unhooked all of the SATA devices except the HDD (the one that wasn't hooked up when the original PSU died). I plug the AC into the PSU, then turn on PSU (not the power switch for the computer, the switch on the PSU). The computer starts flicking on and off in this weird rhythmic pulsating pattern "click...click...click...click..." with about a 1/2 second between each click. Each time the power flicks on, the LEDs come on and the fans spin briefly. The strangest part is that I don't need to hit the power button on the front of the case for this to happen, it just starts as soon as the PSU is turned on. In fact, I can't get the computer to turn on at all--the switch on the front of the computer appears to be dead.
1. Unplug the power cables from everything and re-seated them.
2. Reseated the data cables to the optical drive and the SSD on the drive end, not on the MOBO side as they are covered by my GPUs and I would have to take them out in order to do that.
3. Tried hooking up a SATA power cable from my old modular PSU and using that in the new PSU in an attempt to power the optical drive (didn't work, I know, bad idea--I learned you aren't supposed to do this shortly after I tried it)
4. Setting all preferences to default in the UEFI.
5. Disconnecting the power cables from one or both of the GPUs.
I think that this is either a problem with (1) the motherboard, (2) the new PSU, (3) all 3 SATA devices (unlikely). The fact that I can't even get into Bios anymore tells me that this may be a MOBO or PSU issue.My main question is how to procede from here? I suppose I can wait for my Seasonic to come back from RMA--perhaps that will clear up the issue. I just can't shake the feeling that this is a MOBO issue though. I am worried that if I keep screwing around with it I may end up frying my CPU and GPUs. I can eat the cost of a MOBO or PSU if necessary, but I can't afford to buy a new processor and two new 670s.

Keyboard and mouse drivers unaffected.USB Mass storage device properties messagewith driver check on:"Windows cannot verify the digital signature for the drivers required for this device."with driver check off:Tells me drivers are corrupt or missing.Search show diver where it should be:C:\Windows\System32\drivers\usbstor.sys (also usbfilter.sys).Used the HP Recovery Manager to restore factory setting for USBStor.sys, it indicates it is successful but no changeon reboot, still cannot use flash drives, SD cards, external HDs. Units work find on my laptop.Called HP 4 times, after extensive troubleshooting each time, following their instructions, go to hp.com/go/instant, get screen saying request has been received. Each time tech tells me he cannot find my request.After a while, read 2 hours, told they need to talk to supervisor, will call me back, KISS OF DEATH, never hear from them.

I have been unable to connect to anything on my wired network, for about the last week. I don't remember making any changes however, I just became unable to connect.I having done a little troubleshooting.1. I can connect to the shares of my Windows Home Server if I use the IP address. The name does not resolve.2. Flushed DNS and restarting DNS server. Flushing DNS works on one client, to allow browsing by the name & restarting DNS works on the other. However neither works after a restart.3. Only my Wifi clients are experiencing this issue. My wired clients, desktops, PS3, Xbox 360, and Boxee can connect perfectly.This issue is not limited to my server. I can't connect to shares on my desktop, nor print to my wired printer.Some network background:I have DSL through CenturyLink and have a Linksys E2000 router.

I have begun experiencing random shutdown with my system. I recently re-built my first build adding an SSD, new motherboard, graphics card and memory. [code] I ran the SF Dx tool and included screen shots of CPU-Z tabs and CBS.log filtered for just the SR (system restore) points from the sfc /scannow. Included all files in the zipped Seven Forum folder attached.random shutdowns-periodically I will return to my computer and find a screen asking for a boot drive. hitting space will not work.i have to shut down using the power on button.Usually it boot into windows after the first time.Occasionally I have to power on and off a couple of times.screen bland for 10 to 20 seconds. Occasionally while switching between applications using Alt-Tab the screen will go blank for up to 20 seconds.It recovers on its own with a message saying my GPU shut down and was restarted. I have never actually seen a BSOD (am I in the wrong forum?) but would like to fix these problems.For a time I thought these were problems with my SSD and GPU but when I ran sfc and saw the number of files that weren't repaired I started having concerns.Oh and by the way I have run a variety of diagnostics on the SSD and GPU and nothing was revealed.

I thought I had this problem fixed but I guess not. My computer will randomly turn off (as if I unplugged it) at different times. I have had it done twice in the last hour I tried removing RAM in case that was the problem NO CHANGE. I bought a brand new power supply yesterday because I thought my old one was bad. It is a thermaltake 600 watts, which is more than enough to run this PC. A few days before that I got a new motherboard from the manufacturer. I am literally stumped, the only other thing I can think of is if my power switch is getting stuck. I have no idea how to replace or rewire a switch though besides getting a new case.

I was having some BSOD issues but they seemed to have been resolved. I have gotten a few random freeze then auto reboots. When it reboots it says "loading intel boot (something)" but then says there is no bootable media. I hit power to shut the pc off then hit it to turn it on and it boots like there is/was no problem. I have been trying to track and see when it does it but I cant seem to find a trend.

I have an acer Extensa 5620Z laptop and recently, without any warning it just restarts. A blue screen appears out of nowhere and then the computer restarts. When I was able to choose how to restartt I chose safe mode and went to the event log where it said "The driver detected a controller error on DeviceIdeIdePort2.". I have no idea what this is and I've seen a bunch of stuff talking about reconnecting thing and adding new roms

I'm just trying to figure out what exactly is hanging my reboots and shutdowns. I get to the shutting down screen in no time but it just sits there for like 2 minutes then shuts down or reboots. Obviously something that is not expected and kind of annoying.

Battlefield Bad Company 2 and Crysis 2 have caused my computer to totally shutdown without warning after about 20-30 mins of play. Then after maybe 3-5 mins after the shutdown the computer restarts its self. First game I installed into this machine was Shogun 2 and I did not have a problem with shutdowns. However I haven't played that game in awhile. I am going to format harddrive and reinstall windows 7.

I recently reformatted my laptop and did the necessary steps in order to ensure everything was back on track. Unfortunately, yesterday when I tried to play Mass Effect 2 on Steam, my computer shut down without a BSOD or any other error message. I thought it might have been an overheating issue (I have never had an issue like this with my ASUS laptop, even while it was overclocked to the max through the ASUS utility). I figured it might be a one off, and decided to give it another go. Unfortunately, it happened again 20 minutes later as well.I was hoping someone can help me decipher the Event Viewer information and whatever else you may need, so I can fix the issue and beat Mass Effect 2 before the third one comes out.

Before this problem happened, I downloaded my GPU enhancing software. It kinda screwed the graphics and I think at this point the problem began.I don't know how to copy the what bluescreen said. But I think it said some new software or hardware causing the windows to not function properly. So, I deleted the GPU enhancing program completely (I thought it would be bertter to do recovery, but there was no critical update.) Deleting it fixed my screwed graphics but not the bluescreen problem.

I am having my pc shutting down randomly when I say this I mean a blank screen no BSOD and when I turn on my computer then go in to the event viewer I get the following:
Critical error: Kernel power 41 (63)
Alongwith a sidebyside 33 error with comes a few seconds before the power error, to give to background this wasn't happening before I download this game and installed it but I have done virus scans and nothing turns up i have even reformat and it stills continues to happen. This is actually the thing I download: [URL]. Actually the last time I had a virus scanner open I also had cpu-z and I was noticing that the cpu % of use was going up a lot from just that and then the temp kept going up as well at one point it was 80-90 degrees

So my computer running Windows 7 64 just yesterday crashed twice with BSOD. First was a stop: 0x0000001e and the second was a stop: 0x000000a. Since then my computer will randomly force-close all my programs and revert to the login screen saying "Shutting down..." and the computer will restart. I am no longer getting BSODs, just this. It occurs. Regardless of what I'm doing and no more than 10minutes logging into windows. In fact, even if I let windows sit at the login screen without signing in, it will still shut down and restart.
It also does this in Safe Mode.
Before yesterday, I had no problems with my computer. Now it forces a shut down. It's not overheating - I can check my temps before windows shuts down and my i7 idles around 45.
I looked around the event log and found an eventID: 109 "Power Kernel has initialized a shutdown". But no idea if that's indeed what is causing the problem or how to interpret that.
keep in mind that my computer was working perfectly less than 12 hours ago. No new download, no new drivers or hardware, no new software.

When I first installed windows it started to work just fine but I soon noticed that it would randomly freeze every 15-30 minutes of use, but not on a particular program or anything. I assumed it was drivers so I installed the latest drivers for my GPU and MOBO and keyboard. It seemed fine again until it started crashing again. I ran a GPU burn test and a CPU burn test it passed both. (I tried runing memtest86+ but it froze at like 12%) Then I tried fixing the registry so I downloaded ccleaner and fixed the registry problems. Freezes continued. I finally decided to re install windows so I did and the problems still continued. I am at a loss of what to do and can't think of anything else.

Computer is currently suffering from persistent freezing and bluescreens. It seems to happen almost randomly, and usually very soon after startup and loading of Windows. System restore has not helped.'fraid that's all the info I can give right now. Any recommendations? If anyone wants me to run hijackthis or dxdiag and post results I'd be more than happy to (assuming I can get that far before it freezes!). Safe mode does work, and the problem does not occur while in safe mode.
