My Computer wont turn on

by squadexodus / December 27, 2007 3:01 AM PST

My computer wont turn on when i hit the power button in the front, although i know the mother board the gets power because there is a led that lights up when theres power. First my video card made my monitor say no signal, and a few days later my motherboard stopped working. Any ideas whats wrong?

no signal

No beeps?

Your monitor said no signal, not your video card. Monitors have their own programs internal which tell you the video card isn't sending it a signal. What LED lights up? The harddrive led or the memory led on the motherboard?

I'd suspect either power supply or blown capacitors on the mobo. I think your mobo is in that time frame of the bad capacitors. Look on it around the CPU area for large capacitors and see if they are leaking or pushed up off the board. If they aren't sitting straight, but tilted then it means they are blown at the bottom. Here's an article about them.

The Led is right between The last and second to last PCI Slots, And whenever i turn the power supply on, it turns on, and if i turn off the power supply, the led goes off.
I would think that if the computer wont turn on when i hit the switch, the hard drive lights wont go on.
Ill check the Capacitors.
I was planning on getting a new video card, then a motherboard, but it looks like the mother board and cpu are next.

About Bad Capacitors

In reply to: Led

I had all sorts of intermittent problems on a mobo that I finally tracked down to 5 blown capacitors out of 12. One of the problems which became much worse at the end, caused by the transient ripple voltages (capacitors smooth out those) was odd video characteristics. Since it had integrated video,of course that got tossed with the board. What I'm saying is your video card may still be OK, so hang onto it and check it on the new motherboard. Anything you thought was a problem related to it was likely the fluctuating voltages or ripple effect allowed by the blown capacitors.

I think the problem lies on the motherboard,i faced the same problem before and after a new motherboard being replaced,problem solved.

I checked, and there were no bad ones. Its not the PSU either, i switched it out for a brand new one.
I guess ill just have to wait to get a new one...

Bummer...would have made a new MB so easy to justify.

While you're in there...might take the opportunity to swap out the CMOS battery.

My daughter had an ASUS MB that failed because of bad caps and I replaced it with an MSI that succumbed to the same fate within a year

check out Gigabyte's new all "solid" capacitor motherboards. One of those will be my next one.

Im gonna get a Abit IP35.
Also a dual core 2.66
Its a bit expensive

Looks good

Abit was the one manufacturer hit the hardest on the exploding capacitors, and I do mean those on their boards were exploding, lol. They were more honest about it than the other mobo makers, but ended up bankrupt and got bought out. I see that board has solid capacitors for the main power ones, and only a couple of the better brand electrolytic capacitors on it elsewhere. Hopefully Abit can get their sullied reputation back again.
