Title: PC doesn't always start, Fans on, Power LED on, no beep
Post by: keval5531 on April 26, 2014, 02:26:13 pm

Hello forumers, I am new here. Please help me out, I am stuck with a problem.
MY PC's specs:
Mobo: Gigabyte 880GM USB3
PSU: Power Focus 550W (a local brand, yet better compared to other locals imo)
RAM: 2 * 4 GB DDR3
Proc: AMD x4 955BE 3.2 GHz

Problem: It started 2 days back; I couldn't hear the POST beep when I powered it on. So, Power LED is ON, Fans are running but no video & POST beeps.
I used the power button to switch it off & hit it again. It worked. Though I was taken to BIOS Checksum Error page & I loaded the default settings.
Once I take away the power supply & switch it ON again, it's highly likely that it wont work. And if I try to switch it on after waiting for 15-20 mins, it surely won't boot at first attempt.

So, problem started 2 days back. I was frustrated, tried to find the problem. Took out all the peripherals to test, still the same problem. I removed the heatsink, cleaned the processor & also cleaned the RAM sticks & tightened all the plugs. Still nothing worked. I thought it was dead. Though, I decided to try the method of letting the fans run for a long while & then power my machine off & restart. I let it run for 20 mins, no luck. Then next shot was 1 hour+, it worked.
Then I decided to not take the power supply, restarted multiple times, 80% of the restarts gave me the BIOS checksum error, where I loaded the defaults.

Some things that might give you a clear picture:
1. My city, Mumbai(India) has been hot lately.
2. The power button on cpu responds only if pressed within a minute or 2 after booting.
Okay, I guess whatever information you'd need is given. So, what could be the problem? What failing hardware would cause such issues?

Hello,
This part of your description I do not understand please?
quote "Then I decided to not take the power supply, restarted multiple times, 80% of the restarts gave me the BIOS checksum error, where I loaded the defaults"
What do you mean by this please?
My first thought would be power circuit in PSU breaking down under-load or when getting hot. This is normal symptoms for a PSU with intermittent circuit failure.
This would explain why the system can power up after the PSU has been allowed to cool down.

Nevermind, it was my motherboard. Warranty was available, so I got it fixed.
