Help: PC doesn't start immediately

[lao3hero]

Hi experts,

recently my pc started to have this problem: When I turn it on, it would not start immediately but would sometimes start suddenly on its own a while later, at times about 15 mins later...

Brought the CPU to a repair shop and they solved it. But when asked, they said they are not sure what was wrong; all they did was to remove all cables/components and fix them back.

For a while the CPU was normal; it would boot immediately when turned on. But today the problem came back...

Could anyone help with this? Thx!

How old is your computer? You might have bad capacitors. http://en.wikipedia.org/wiki/Capacitor_plague

Hi, thx for replying!

I can't remember but it should be 2-3 yrs. I did take a look at my mobo previously but the capacitors look ok...

I do notice that my system clock in windows is out of sync too. It should be just a coincidence that the cmos battery is flat ya?

Thx again.

possibly a bios issue...but what do you mean by flat? the batteries yes are flat in appearance...

Yeah a dead CMOS battery could do that. Try a new one.

"flat" as in out of juice...

more details would be: When I press the "on" button, it would not power up immediately, often only after a few minutes. But yesterday was the worst happened; it can't be turned on anymore.. However, the LED of an USB dongle plugged in is lit.

Btw, thx to all for replies. I prolly will try a new cmos battery first 🙂

try to hard start the PC from the jumpers on the MOBO instead of your switch on the front. See what happens

Look at a manual for that MOBO or look at the small two wire cables going to mobo from the front switch and find one that says pw switch or something along those lines. Then unplug that cable and use a small screwdriver and jump the two pins together and bam it should act like the front switch.
