Question about Asrock 775VM800 Motherboard

1 Answer

Unknown Shutdown My computer froze up on me, and I rebooted. After the reboot, it still remained sluggish. It then shut down completely and will not power up. When I open the case, and look at the motherboard, the fans for the cpu and the case start up briefly ( about 3-5 seconds) then shut off. What could it be? I think it's the motherboad, but how can I tell without swapping it out with a known good one?

    I tested the power supply also. I forgot to mention that in my previous post. I thought it was the power supply at first, but because I was getting power to the cpu and to the fan on the case, even though it was brief, I ruled out the power supply. I even tested it with a multimeter. I haven't tried to swap drives because my main drive (the one with the OS on it) is a SATA drive. I don't have a back up SATA drive to test. My other drive is an IDE and is simply a storage drive. I didn't think of the RAM as a possible problem. Could it be anything else besides the power supply or the RAM?

    I'll try the RAM. If that doesn't work, I'll try the CMOS battery. I never overclocked the system.

    I'll give it a try. Thanks.

I think this may be your power supply failing. That would be the best place to start. What you could do for debugging purposes is remove all unneccesary components (extra CD drives, extra PCI cards) and test the system then. Also test the RAM to make sure there is not an issue with one of the sticks (although, the computer would most likely beep at you if there was upon power). Also, if you have a backup harddrive, try swapping it with the current one.

I would mostly guess it is the power supply though. If you have a backup or spare computer, try connecting the power supply to that one and see if it boots ok.

    The RAM could actually be a problem. Try taking it out, clean it off (air can or something, and the contacts on the mobo) and put it back in.. You could also try swapping the CMOS battery with a new one, as it can sometimes cause these types of problems.

    Another thought, have you overclocked the system at all?

    If none of those things work. Perhaps you had a power surge and in that case, what you could do is leave your system off (and unplugged) for a couple of days to let the power supply discharge fully, and then plug it back in and turn it on. Sounds strange, but might just do the trick...

Bought the computer (with ECS HT 2000 Dual DDR 800 MB) 2 months ago. Two weeks into it, the screen goes black; but the ''no signal'' that normally appears in the middle of the screen, when the computer is...

Send the dealer a letter informaing him that you intend to file a small claims action against him to recover the $65 and the cost of the computer, because it is defective.

Also notify him that he has 15 days to respond. Then file a small claims action against him to recover those damages.

It would be in your best interest to try to find out what kind of warranty he offers with machines that he sells

Computer does not reboot after a reboot command

usually it's a faulty RAM, doesn't it show an error on/during POST ?!?!
maybe just a loose connection between board and keyboard?!
if you can, debug the process:
1 - check cables
2 - disconnect all cables except keyboard, mouse and monitor
3 - open the case
4 - how many RAM dimms?!?!
5 - if more than 1, remove one of them and REBOOT
exchange them and reboot again.
this should help to identify the problem.
if all fails.... maybe a faulty board, or processor.
or some pci card.

Windows will not turn computer off. I have unpluged every thing and all fans but the hard drive. I get 0.01 dcv when the computer is running and the same when I try to have windows turn the computer off....


This usually happens if Windows is having trouble closing a program. The easiest way to avoid the problem is to close all programs before you close Windows.

If that does not help, you need to track down which program is causing the problem.

If you are running Windows 95, remove all shortcuts from your StartUp folder.

If you are working with 98/ME/XP, uncheck all the programs listed in StartUp in the System Configuration Utility (you get to the utility by opening Start/Run and typing "msconfig" without the quotes in the Run box and then clicking on OK).

Shut down the PC. Reboot. Shut down again.

Then add one program back, shut down, reboot and shut down again.

If Windows shuts down as it should, add a program back to StartUp and repeat the shutdown, reboot, shutdown routine. Do that until you have pinpointed the errant program and reinstall it. If you are running a screen saver, consider it also to be a prime suspect.

Your Advanced Power Management, or APM, utility has decided to take leave of its senses.

Disable it, both in your BIOS file and in Windows.

That little sound riff that accompanies the shutdown is hitting a sour note.

Go to Control Panel and click on the Sounds icon to open the Property dialog box.

Scroll down in the Events box until you see Exit Windows. Change the sound settings to None.

Your TEMP folders are bulging at the seams.

If the C:\Windows\TEMP folder gets overloaded, all sorts of bizarre events can ensue. Clean it out. While you are at it, clean out your Temporary Internet Files folder as well.

Updating XP with the latest Service Pack may also cure the shutdown failure.

However, it is also possible that Advanced Power Management, or APM, is getting in the way of the shutdown routine.

APM may not be enabled in your XP configurations, but it may be turned on in your BIOS, a memory-resident program that controls how your PC sets itself up.

Microsoft recommends that you go to the Control Panel, click on “Performance and Maintenance,” and choose Power Options.

Click on the APM tab and click on Enable Advanced Power Management Support.

Personally, I don’t like automatic power management on desktops because it can cause all sorts of bizarre behavior. I would leave Advanced Power Management disabled in Windows and turn it off in the BIOS.

Consult your PCs manual to determine how to enter BIOS’ Setup file. Sometimes, as the PC boots, you can see a message on the screen that tells you which key to press to enter Setup. Press it before the screen welcoming you to Windows appears.

Once in Setup, look through the various sections until you find the option for controlling power management. Choose to turn it off.

For guidance on other XP shutdown problems, consult article 308029 in the Microsoft Knowledge Base. Use the article number as a search term at the support site below. Good information is also available at the site.

Can not save to bios

windows and the bios needs to know that the operating system can be shut down through windows, so when you go into the F2 or Del on boot up, go into advanced cmos setings and look for ACPI and make sure it is enabled. This sets the motherboard to support shutdown. Save and exit settings and reboot. Now go to control panel>performance and maintanance>power options and set the correct instruction for shutdown to shut the pc down. Remember evertime you remove the cmos battery or reset with jumpers you have to reset date and time and anything else you have changed to suit your set up
