Last night, my house lost power and this morning, power back up. I have two computers and both were on surge protection. One came back up fine this morning. The other computer will start powering up but will not boot up on the monitor. The monitor shows no signal and goes to sleep. Fans come on normally but the fan to the power supply is noticeably very loud. Also the green light comes on the motherboard. The computer is not providing me with any beeps or blinking lights. I have attempted to bring up BIOS to see if the power supply is providing proper power but no luck using the F9 or the escape key. I also unplugged the computer, hit and held the power button on for 30 seconds and tried a restart. Same problem. I pulled out all my RAM and tried a restart. Same problem.
I considered using a multi-meter to test the power supply but it is an HP power supply not using the standard 24 pin connector. And I don't have the background info to test it.
I suspect the power supply because the PS fan goes to high within a minute of power up but I also have suspicions of the motherboard. I paid $150 for it last spring as a used computer because it had windows 10. I use it as my internet computer. My other computer is win 7 and I normally will not use it on the internet. So I can replace the power supply used for around $20 and get my internet computer back running if that is the problem. But it is a wasted $20 if it is the motherboard. If it is the motherboard, I should probably start shopping for another used computer.
Any ideas for narrowing down the problem or are there other possibilities which I haven't thought of?
