Hey, So I was having an issue with my computer (it had worked fine for a year now), I would attempt to boot up and all the fans would go on, whizzing, but now there was no signal on the monitor, and the keyboard lights would continuously flash. So I tried a different graphics card, then I just tried using the onboard graphics, nothing. I tried new RAM, nothing. I undid allll the IDE channels except for the hard drive, still flashing keyboard lights. I bought a brand new power supply, nothing. So I thought it might be the motherboard, I called AOPEN, they sent me a brand new AK79G-VN motherboard, I transferred everything to that motherboard, and I STILL received no signal on the monitor, and flashing keyboard lights. I've tried clearing CMOS/BIOS, did nothing. HAve undone the front panel connectors, re-connected them, tried new ram, tried new power supply, tried different graphics cards, tried one IDE channel, tried new motherboard, I think I've tried just about everything but a new processor, which I don't want to invest in unless I KNOW that is the problem, but I really doubt it is, the processor itself looks fine to the eyes. I am unsure of what to try next and what flashing keyboard lights mean, any help is greatly appreciated,
Trev

Hi SirTrev, welcome to SAF

Just wondering, have you tried another keyboard??

Someone will try and help you.

Actually, I was thinking the same thing. A dead keyboard can cause a short and prevent the pc from booting (not sure about flashing lights though).

Wow, thanks for the speeeedy response, as soon as I read that, I tried it. Yeah, how embarassing would that have been if I just spent a hundred bucks on computer stuff and turns out it was a keyboard. Sadly, it wasn't, I tried my two other keyboards hanging around the house. However, they both did NOT continuously flash. Still nothing on the monitor

The second thing I would suspect is the PSU. Power supply units fail a lot. You can get a PSU tester pretty cheap before you buy a new PSU.

Check THIS one at newegg.

from everything i've read in trev's posts it sure looks like it's the processor. looks like (from motherboard numbers) the processor is amd socket 462 of some kind and the processor core chips easily. the smallest crack or chip usually kills them. if the heat sink and fan aren't seated properly then the processor may have overheated and fried. either way sure looks like a processor issue.

I just got back from a friend's house, tried his power supply- nothing, tried my PS on his, worked fine. Pretty sure it's not my brand new power supply.

And Wes- yup it is an AMD socket 462, AMD 2700+, and there are a FEW almost unnoticeable scuff marks from rough heatsink removals... Not something I would expect to see something like this resulting from. But the more I look over the situation, it seems like that's the only thing that makes sense, I just keep hoping I missed a wire, or a jumper or the HSF isn't on tight enough or something.

one thing that can help is to install a shim that goes between the hs/fan and processor to keep the hs from rocking too much. almost all the hs/fan places online sell them for around a couple bux.

Hi SirTrev,

Unfortunately, as you tried everything, Wes may be right although we all here are crossing fingers to be only a jumper/wire issue

Triple check them all carefully, step-by-step and maybe you'll find something.

Post back if you find something

Just another thought SirTrev, did you try the monitor on another computer??

That's the only thing, I don't see that you checked.
