I was stuck with this problem for several days, thinking the motherboard ethernet chip may have died. I was about to buy a new PCI ethernet card, til i found a post that saved me. All I had to do was to turn off the computer, unplug the PSU, leave it off for a few minutes, then plug it back in and boot again, then it worked again!!!

This is just a shot in the dark: I think you have some sort of issue with cables - perhaps even issue inside LCD panel itself. If your laptop is still in guarantee period, simply send it to service. If not and you are handy enough, try (with caution): disassembling the laptop unplugging LCD cable from motherboard and LCD panel itself and plugging it ...

IN most of the cases in it a problem either with magnet heads (assembly). Heads mounted on Head Stack Assembly or HSA. When the computer starts up during the POST procedure HDD is initialized (firmware, size, parameters, mode, interface) and reported to BIOS. During this phase HSA goes off the landing zone (where is it parked) and the heads are reading ...

It's likely CPU/GPU/NB chip dead. Requires repair by chip replacement via soldering. In this model integrated video is on-chip with north bridge and CPU. It can be a LCD matrix or a cable from the motherboard as well. This can be verified easily: connect external display - if the picture is fine on the external display then the issue is with the display.

The best way to test the HW is run Windows Live CD (Windows PE) running from CD/DVD/USB. First of all I advise to create a bootable CD/USB to boot from with test utilities. Run Memtest86+ from DOS mode to test RAM. After that Boot to Windows PE and start working, run test utilities to load CPU/RAM and hence, to consume more power. You can use AIDA64 with ...

As per this manual http://support.hp.com/us-en/document/c02222922 5 short beeps - BIOS recovery successful. You should reset BIOS using jumpuper or pull off the 3V battery for a minute.

Expanding on Hardorman's answer. Even if the fan is 3-pin it may still be controlled by the GPU. The common pinouts are: Power [red] (Always) RPM control [usually blue] (sometimes) RPM feedback [usually white] (also sometimes - more likely if there's RPM control) Ground [black] (Always) If you have the tools (depending on the connector), pull all of the ...

If the GPU fan has 3 pins it is no spin control and a signal should be supplied to it constantly (via red wire with +V positive voltage). Voltage is supplied from the video card. Using voltmeter you can check voltage between the red and black (its ground) wire. If it's wrong or missing when the fan stopped - you can supply +12 V from external source wire. If ...

It is hardware failure. if you've checked PSU/HDD, it is very likely to be a motherboard or overheating issue. I suggest to disconnect all other devices but CPU and RAM, start PC and pause it at BIOS stage. Wait until it gets shutdown. If so - it is faulty motherboard (often electrolytic capacitors fail). Also you may verify RAM consistency using DOS ...

There are 2 types of backlights: LED and Cold cathode fluorescent lamps (CCFLs). In case of CCFL they are dimed by a driver (called invertor). It is located in the bottom of the screen assembly as a separate PCB. You need to replace it. IN case of the LED backlights driver is often integrated on the rear part of the screen, so you'll need to replace these ...

Every HDD has a number of unused sectors that are preserved from the factory for the relocation events. Once HDD firmware detects unreadable sector it "replaces" it with the healthy one "from the stock". In fact, nothing is really moved, it only records that instead of sector xxx sector yyy must be used. This is called sector relocation event. If it started ...

Finally my problem is solved when I changed my mainboard. It seems to be a problem with mainboard, but I couldn't exactly figure the details out.

It could be that the motherboard doesn't have support for the CPU you're trying to use - look up in the manual and see if you need to update the BIOS before using the CPU you're installing on the board: https://www.msi.com/Motherboard/support/970A-G46.html#down-manual Take a look here and see if your processor is mentioned in any of the BIOS updates as "...

It's possible, looking at the pattern of the damage and the way it lines up with the wiring along the battery compartment's backplate, that the is an electrical short or something similar causing extreme heat generation in that location... That certainly appears to line up with the location of the damage, at least. If you could identify what parts those ...

Try running it alone, everything unplugged but the bare minimums. No VGA? I'd figure there's no HDMI on the MOBO, but you'd think there's a VGA port. It should POST without memory or SSD. See if it POSTS and then if you can write down the BIOS name and version. You'll be able to compare that to the lists of compatibles with AMDs. BIOS settings may be ...

Since you said that applying pressure by the Esc key, my guess would be that the flex cable that connects the display to the motherboard is damaged or loose. I recommend changing it. Sometimes, when such cable damages, certain issues can occur. For example, the screen splits in a strange way, black color appears washed out, some colors change for others (i....

Without actually seeing the state of the laptop's physical condition and running some diagnostic software on it, right now, a best guess is about as accurate as you are going to get. The laptop fell. This can cause all sorts of problems. You mentioned that the lid wasn't aligning properly any more so that means there is some breakage and/or twisting of ...

Other than it being extremely annoying, you won't damage anything in your computer. If the temp threshold is exceeded, your computer will slow the processor and eventually shut down the computer to avoid damage. If you put an small portable fan to blow air into your case, you should be fine. I have done this in emergency situations when a fan died on a ...

If you have a voltmeter, it may be helpful to check the voltage across the fan when it is running fine (5v or 12v) and when it's making noise. If the voltage drop is significant, it could be the stator coils shorting, causing desync. This could eventually result in a dead-short failure, possibly damaging the motherboard, or depending on the power supply, ...

The power supply is the most likely thing to permanently damage the video card. That said, the video card is also plugged into the motherboard, so a motherboard giving electricity to the video card could also be an issue. I would definitely also consider replacing what you plug into the video card. Try another video cable (which might, or might not, be ...

On the short term - it should be fine, unless there's obvious issues. Its a high end PSU with a ton of legs. You do want a more modern PSU eventually - there's no support for c6/c7 states in older PSUs, and that may cause issues, but the fix is trivial - turn off those states in bios if you have issues. Typically when a PSU does die, it rarely takes out ...

Well you're right to describe it as hardware failure if the broken card did not work in another computer after this began to occur. Unless there has been physical damage from impacts or water to the graphics card, its most likely due to damage from an overload of power - make sure that the wattage on your power supply is appropriate for your system. That ...

Wireless mice (mouses?) sometimes build up static electricity in the micro switches and cause eratic behaviour like the poster describes with dragging and double clicking problems. You need to discharge that static ... here's how: Turn on/off switch to off. Remove batteries. Click all buttons and clickers and wheels for at least one minute each. Re-insert ...

I'd suspect, that those drives haven't failed at all - they were just running out of their specs and should be fine when plugged into a different computer. Let me explain: You use the USB ports of your Yoga for two purpouses: As a data connection, all fine with that As a power source for the drives, and that might be the problem. Now the Yogas are ...

A Compaq laptop running Vista sounds pretty old. This sounds like hardware failure. I would, at a minimum, boot up a memtest86 CD and fully test your RAM.

First and foremost: I wouldn't recommend trying a suspicious PSU in a computer. Try the rest of the components. Think of what could have happened if the PSU was the faulty component and was supplying overvoltage. To answer your question, USB faults shouldn't be able to fry a whole motherboard, but it can happen. Now, considering that your computer doesn't ...

Sounds like ultimately you may need a new motherboard. As for how to diagnose it, a multimeter may help in determining if/how many USB ports simply don't work anymore. If they don't read 5v, they won't work. I suppose it's also possible they are delivering 5v but the data is down (governed by a chip on the motherboard). Your CPU should be fine but until you ...

you need teer down your laptop and clean heatsink, heatpipes, CPU fan from dust, take off termal compound of CPU and GPU chips and apply new one (cooler master for example). if you can not do this, take your laptop to service and they do this job for you, good luck

It clearly says which disk it is. \Device\Harddisk 1 \DR3, so it is referring to Disk 1. The DR3 part at the end is some kind of identifaction to which partition it is referring. Do note, a controller error is not like bad sectors though. Chkdsk may make the drive become permanently unavailable. You should take this warning and start doing backups.

You need to get a new hard drive, and clone your this drive to the new drive before your problem gets worse. If it can't re-allocate a bad sector its used up the spares. I don't know how many of these you have in your log file for different sectors, but your hard drive is on its way to failure. It might not be dead for 6 or more months but when it dies ...
