Hope this is appropriate for this forum. Have a 3 year old computer I assembled that has a Intel D845GBV MB. This machine now has three problems and one of them is now intolerable. I’m not a power user so I’m not compelled to move up to the latest and greatest.

Problems:
1. The monitor has a rose colored tint that I am unable to remove through the Win XP adjustments or the adjustments on the monitor. This has occurred on two monitors. The monitor adjustment displays (not the computer) are nice bright sharp white, blue and black like they should be. This problem first presented itself as immediate change to in which yellow replaced white. This would last for a few minutes or several days and then return to normal for long periods. Now the red tint is here for the duration and it is impossible to set contrast brightness etc. Any suggestions would be greatly appreciated.
2. Each time I connect any USB device a warning will appear in a short time - “POWER SURGE ON HUB PORT” followed by “A USB device has exceeded power limits of its hub port. For assistance in solving this problem click this message". The nonsolution is to reset the usb port but the warning reappears as soon as another USBdevice is connected. I checked the Intel Active Monitor and all temps and voltages were within range. Any suggestion?
3. The USB ports frequently won’t wake up if the computer has been idle for a period of time. It is necessary to turn the device off and then back on.

The first problem was a defective video cable. Both USB related problems remain.

Welcome to the forums, glad to see that it was the video card, thats kinda what i would have suspected. as for the usb are you using a hub? I have seen a similar thing on my gf's computer where it will not wake up. I still cant fix it.

I'm not using a hub, just the two ports available at the front of the case. I'm wondering if I can buy a USB PCI card and somehow bypass that on the motherboard?

do you get the same problme with the usb ports on the back of the computer?? because if not it could be that the front ones are miss wired.

Check the wiring AND vacuum out the front USB ports (with the power off) I've seen a couple systems with a similar problem (the surge thing) caused by a mini dustbunny in the jack.
check the USB power/awake from sleep settigs in properties.
with a 3 year old board, it's possible, some component has /is failing

You might also look at your USB device specs. If they are USB2 devices and you are using USB1 hub it can confuse your system somewhat.

Hi,

I recently bought Antec Super Lanboy case. I transferred the entire computer assembly from my older case to the new Super Lanboy case without any hardware additions (Except for the PSU which is new Antec SmartPower 400) or operating system modifications (Windows XP Professional SP2).

I have connected the front Panel very carefully as stated in the Intel Motherboard's (D845GEBV2) and Antec's manual. I am sure they are correctly connected. However, after that my mass storage devices like Flash drive and external hard drive do not respond when connected to the Front USB ports. The Flash drive hangs the OS completely. I am although able to connect my web cam, digital cam and USB-RS232 Cable successfully through the front USB.

When I bring the external hard drive's usb connector even near to the front usb port (very near but not connected), the OS reports that a power surge has been detected and asks me to remove the device and reset the port. Same when I connect it completely. The device thereafter is never detected. No use pre-plugging the device and then booting the computer also. These devices however, when connected to the back panel usb (onboard) work correctly without any problem.

Notably, these devices use to work perfectly in the older case without any additional changes in the BIOS or the OS settings when connected to the older case's front usb ports.

Also, when I disable HI-Speed USB in the bios (in Super Lanboy's case) and then connect the Flash Drive or the external hard drive through the front panel, they are detected and work, albeit with a message from the OS that these are HI-Speed devices and will work at very slow speed unless I enable/Install Hi-Speed USB. They indeed are very slow in this case and I wouldn't want it to be so.

Any help would be highly appreciated.

Thanks and Regards,

Yippee!!! Got my front panel usb working finally with USB 2.0 devices (Hi-Speed).

I had almost given up and made up my mind to replace the Super Lanboy case with another one. One last try I thought and discovered this forum:

The problem resided in the 10th pin of the front usb connector and mobo which is basically an over-current sensor. Most mobos let the pin be physically present but unconnected on the mobo PCB. Hence, people using those mobos do not face any problem with the FP connector. However, my Intel board apparently has a full fuse and sensor circuitry built on this pin, although the mobo manual shows this pin to be NC (Not Connected) which is rather strange and secrecy not comprehendible.

I carefully lifted the lock of the 10th pin of the FP USB connector and pulled the pin out. Folded it backwards and taped it to the connector cable lest it should touch the components on the motherboard. All my USB 2.0 devices work beautifully through the FP USB ports now.

It makes sense, all those messages from WinXp about “power surge detected” and then asking me to reset the port (reversible fuse on the mobo) and then blocking my usb 2.0 device from being connected, yeah, it makes sense. Especially since a lot of USB 2.0 devices in the market (often by reputed manufacturers) not necessarily confirm to the strict rules laid down by the USB 2.0 specs. It also makes sense why my USB 1.1 devices worked through the FP USB ports. Reason being their low current utilization.

I wonder why the same fuse circuitry is not present for the USB ports on the back panel. Essentially both USB 2.0 and USB 1.1 require only four wires to do the job.

I am surprised at Antec’s tech support. They of all people should have known about this and it would have saved my head banging for two days at a stretch. It is bad business for them, recommending the replacement of case. They lack confidence in their product and someone needs to tell them what a wonderful product they have. Their tech designers must have known why they have put those wires on the 10th pin. I guess their internal communication has room for improvement. Also, why not mention everything in the manual? Same question for Intel too. Too much secrecy leads to bad experiments and waste of time.

My Super Lanboy now rocks and indeed it is the best thing since sliced bread!

Classic and thanks for letting us know what the fix was! Now we all know.
