My computer consists of: PSU: Antec 380W Truepower Case: Antec CPU: AMD 3000+ Winchester RAM: 2x512 DDR 400 Kingston Mainboard: GIGABYTE GA-K8NF-9 GPU: RADEON X800XL Sapphire UPS: POWERWARE 1000KVA The following problem has arisen after some months of use: When I give power by switching on the UPS the LEDs on the keyboard start blinking. If I try to switch on the computer the computer doesn't respond. When the LEDs stop blinking and I try to switch the computer the computer operates immediately. Some times doesn't POST but most times does the POST. If I shut off the computer and I operate it after some minutes the above problem does not exist. I've tried the following: -Using a vacuum cleaner I took the dust from inside and outside the case. -I disconnected the UPS from the computer and I connected the computer directly to the wall socket. Both solutions didn't have a positive result. Can you tell me what are the possible problems that may my computer have and what are the possible solutions? Thanks in advance.
Could possibly point to a motherboard issue... try an ATX reset - disconnect power, hold power button down for about 25 seconds, reconnect power, and boot. Also try removing all peripherals and using power only - watch the HDD light flicker for a short while and then come to a halt - this means it's on the Windows login screen. If the HDD light doesn't flicker at all or flickers very slowly or in a regular pattern then it's likely the issue with pausing at POST is still occuring without peripherals intact. Make sure your front panel is connected to mobo pins correctly too. Hope this helps, Mike
