1372535 2014-04-12 04:15:00 Whenever I turn on my desktop PC, it always takes about 20 seconds at the ASUS screen and then it starts to boot Windows 8.1. But if I restart now, it would go past the ASUS screen in a few seconds and start to boot windows. It seems everytime the computer is turned off for a long period of time - few hours/overnight, it takes a long time to POST. This did not used to happen when I first built the computer last year August.

I have tried adjusting a lot of settings in UEFI settings but problem persists.

Anyone know what the problem is?


(Hardware: ASUS B85m-e motherboard, Intel 4670 CPU, Coolermaster Thunder 600W PSU, Asus GTX 660 graphics card.)

Thanks.

1372536 2014-04-12 04:37:00 Make sure the hdd is the bootdisk. If the cd/dvd, is the bootdisk, it can take longer to boot into windows. And kill the logo in the BIOS. So you can see what it's doing Speedy Gonzales (78)
1372537 2014-04-13 04:56:00 Tried that but no luck. The only boot device the HDD. Turned off the boot logo. It shows a black screen for a while then it comes up with American Megatrends: Total Memory, USB Devices Total - 0 Drive, 2 Keyboards, 2 Mice, 3 hubs.

1372538 2014-04-13 09:02:00 Have you connected any external USB devices?? Speedy Gonzales (78)
1372539 2014-04-13 09:13:00 And what BIOS is on it?? It's up to 2.00.02 Speedy Gonzales (78)
1372540 2014-04-14 11:29:00 Sounds like a cold fault with with either the mobo or graphics card. I would pull the graphics card and use onboard graphics - try starting up after system has cooled down. If it still is slow to boot, turn it off again then prewarm the mobo with a desk lamp. If it then boots quickly, mobo could be suspect. This type of fault was common with failing capacitors, but it looks like your mono has 'solid' caps, that shouldn't fail in this manner. wuppo (41)
1372541 2014-04-15 05:52:00 I have a dongle for wireless mouse/keyboard, and a USB-powered hub. The reason for that is because my mouse doesn't work with a USB-extender cable (I don't think it gets enough power). When the mouse is connected to this small USB hub, it works fine.

I removed the hub from the computer before boot and it booted fine. So the problem is now with the hub...

1372542 2014-04-15 10:37:00 Maybe the hub has bad capacitor(s) - try heating it and see if the problem goes away Agent_24 (57)
1372543 2014-04-17 03:41:00 Have further isolated the problem. It is the mouse itself. The mouse is an AJazz Ray-Eagle (bought from aliexpress - goo.gl). I opened it and there are a few capacitors inside. Mostly polar and one non-polar. I'll see if I can somehow fix it, otherwise no big deal..

As long as the motherboard isn't stuffed I'm fine. Thanks for the help.
