Was working fine , but one day cannot switch on, changed power supply
changed ram, VGA pci express card works fine on another cpu, but there red led on is lighted on motherboard, cpu fan is not working , pls help.
I just lost my fourth KN8 motherboard and it always seems to take out the power supply unfortuneately. One I returned for the 3 year warranty and as a replacement it worked less than a month. These were on 3 different machines(cases and power supplies of various suppliers) so the mother board is the fault.
Will be hesitant to use ASUS boards again even though this may be isolated to this board only.
I dont know about the red light, but all main boards these days have a built in protection if the cpu fan quits. check the cpu fan connection, ensure that it and the heat sink are dust free. if still no go. update your question with exact info..e.g. does absolutely nothing.. how many beeps you hear..how long b 4 it dies.. final note: be careful what you touch.. static can harm more that most think and the oil from touching can retain heat.

you need to open cpu cabinet. Open back cover of cpu then refix the RAM memory. Pull cmos cell from motherboard for 10 minutes then put it back then all settings defaults. Make sure RAM is working fine. Try with another RAM .If you use 2 RAM memory then check with only 1 RAM 1 by 1. Open processor fan and processor then put it back . Clean dust from all parts . Reconnect both connection to harddrive. Make sure motherboard don't touch the cabinet. Remove pci card if any reattach vga card if you use pci vga card.Pull cmos cell cell from motherboard for 10 minutes then reconnect it.Then check. Let me know if you need further assistance. Thanks for using FixYa.
Two beeps means that you need to check your RAM. Try changing the RAM module and see if it working? If you have any display card (AGP/VGA/PCI or PCI express) installed then you need to check that it is properly inserted in the slot in the motherboard. Also check for any loose connections in display card.
The Abit IP-95 manual doesn't show you how to adjust your bios settings when adding a PCI-E x16 graphics card. When adding a PCI-E card you'll need to adjust a few settings within, Advanced Setup. Press the delete key on your keyboard every two seconds to load your bios menu. Within Advanced Setup look for, Onboard Device Configuration and open it. Find, Primary Graphics Adapter. Set this to read as [PCI-E, VGA] save your changes and exit. Currently your onboard graphics is enabled. You'll need to change this setting to PCI-E first. When you use the onboard UniChrome Pro 2D/ 3D Graphics & Video Controller you are also using some of your system memory to run the UniChrome graphics. Once you enable the bios to boot to the PCI-E card you can also stop using your system memory assigned to the UniChrome card.

As per ur question, this problem occures due to following reason:
1. When ur data cable of ur monitor is bad : Try another data cable this causes only to blink LED of ur monitor which not allows any graphics to display.
2. Your RAM can also be responsible for this problem: If your RAM goes Bad then it doesnot allow any graphics file to load and thus causing not to display anything on ur monitor screen as well as ur system keep restart at POST (Power On Self Test) Operation (When VRAM driver is not loaded.
and the last reason is:
3. Your system is not able to recognise your Graphics card due to Either IRQ inteferance or ur graphics card hardware problem (caused due to bad of VRAM installed on ur graphics card): Remove ur graphics card from expansion slot (PCI-E/AGP)and then plug monitor data cable to normal serial port available in the motherboard (Resides back side of ur system).
Try reinstalling the PCI-E drivers or AGP drivers (if you are using that interface) from your motherboard cd and see if there are any problems with that. Check device manage under system to see if there are any red x or yellow flags next to any hardware devices.
Some iiyama's have 2 inputs. One DVI and one analog. Also, some of the older ones used BNC connectors. What I'm getting at is make sure you have the right input selected in the monitor's menu.
Hope this helps....JF
