Pc turns on for a split second

[probypro]

Hi! This is my first post but im reading this forum before trying to find a solution but nothing works.

The problem is everytime i turn on my computer it only turns on for a split second. No beep.

I try to reseat all the components.
I also clear/reset cmos
I also remove ram, video card, etc in mobo leaving only mobo and psu but still turn on for a split second

Last week i bought a new 600w psu guessing that the problem is with the psu.
But my pc runs normal for only 2 days.
It back to its previous issue that turns on for a split second.

Pc specs
Core i3 2nd Gen 3.75 ghz

Acer H61h2 ad motherboard

2gb of ram and 2gb of video card

600w psu

Thanks in advance and sorry for my english

Hi, try testing the motherboard outside the case with only 1 memory module installed (install the memory in another DIMM socket) CPU and on board graphics. Reinstall the CPU making sure it's properly seated if you haven't done that.

Hi! Thanks for the reply.
I remove the mobo outside the case and place in a cardboard. But still did not work. I also reseat the cpu but no change.
Also when i removed my mobo i discover that it only have 4 screws and 2 of then have only standoffs. Is that can affact on my mobo and cause of that issue??

Thanks

Yep the board could have shorted against the metal of the case, so that means that the board is unfortunately dead, next time make sure that the stand offs in the case matches the holes on the motherboard to avoid these issues.

Thank you again! I just worried if my CPU can be also affected of that issue? Do i have to replace also my CPU ? or replace just the motherboard? Thank you and sorry for my noob question.

You're welcome, its very unlikely that your CPU could have been damaged, but the motherboard would need replacing, and it's not a noob question, keep me up to date

Sir! Now Im Confuse. I just try to turn on my PC, on my first try it turn On, but no Beep. but still Fan is still spinning. I turn it off manually by pressing the power Button. And turn it on again. Now it turns on with beep. and Runs Normally im using it right now.

Now im confuse because I dont change anything in this PC.

Thats because some components(resistors, caps, ic's) might have been damaged because of a short with the case which might be the cause of the problem. You were lucky that it didnt catch fire.

Glad to hear that, if ever get this sort of issue again, do the age old fix of take it apart and put it back together. I really thought the board may have been damaged.

So Sir, is my Motherboard are still good to use? it is not the problem?
I will start to troubleshoot again my PC to see what is the real problem.
Thanks for keep replying! I really appreciate it.

Hard to tell if i cant see your system in front of me, but if everything is working fine just leave it be.

Thank you Sir. I will now again troubleshoot my PC. I keep you Up to date
