I am using a 7 year old desktop as a secondary htpc in my guestroom as a "workout companion". In other words, I play P90X and work out, or play tv shows while I am on the bike.
Unfortunately, it just died, while I was upgrading the ram. I am trying to troubleshoot and would appreciate all ideas.
The machine has an Athlon 64 cpu, (had) 2 sticks of 512MB ram, tried to upgrade to 2 sticks of 1GB ram, ECS mobo, 3 sata hard drives and a GT520.
I replaced the ram, and the computer would not turn on. Pressed the power button and absolutely nothing.
Here's what I tried so far:
1) Put the old ram back in. With two sticks, nothing.
2) Put in one of the old sticks, after a few tries, it started once, but then I manually shut it off. Then I put in the second stick, nothing. After a few dozen tries, it happened to start again, but right when I was unplugging it. (Since then I tried hundreds more times, and nothing)
3) Plugged in a usb hub and it lights up, so usb ports have power.
4) Checked the power button connections, they seem to be still connected, might need to test it more thoroughly.
5) Plugged in a different cpu fan, nothing.
6) Unplugged all the harddrives, and such, nothing.
7) Took out the cmos battery and tried again, nothing.
8) I do not have a spare psu, and taking one out from another computer is too much of a pain.
Can anyone recommend any other tests to figure out what the problem could be?
Could the psu be faulty even though it still supplies power to the usb ports?
What is an easy way to emulate the power button to check if that is faulty? Just connect the two power cables together??
Thanks
