Computer won't POST.

Yesterday, I was playing GTA: San Andreas and my computer seemed to be working fine. When I exited out of the game, my computer just shut off and now it won't even POST. I don't get a beep or anything.

First I thought it was my PSU and tried to jump start it. Last time something like this happened, that helped it at least POST. But it didn't work this time. I looked at the LED Codes on the mobo and I could barely catch what it was on before it shut off. I think it was about to load the RAM before it shut off.

I took out all the RAM and it stays on, but tells me it has no RAM(obviously) by constantly beeping.

Now I tried running it with just the CPU, GPU, one HDD and one stick of RAM. It shut off when I did that. I have four 1GB sticks of ram and tried each of them one by one in the DIMM0 and DIMM2 slots. Still can't get it to start up.

I can't think of what could be wrong. I hope the RAM doesn't have anything to do with it, but it's the first thing that makes it shut off. I'll have just the CPU, GPU and HDD running and it stays on but beeps because I don't have the RAM installed.

My rig that's messing up is in my sig. Any help would be appreciated.
 
Anyone locally who could MemTest those sticks for you?

Otherwise, have you tried DIMMs 1 or 3 then? This is to rule out bad slots.
 
I just tried slots 1 and 3 and it still shuts off.

I live in a small town, but there are a couple of places that do simple computer repair. I don't know if they could test the sticks for me, but I guess I could ask.

What do you mean by "jump start"?

Unless you have spare parts of your own, your best bet would be to work with the local PC repair shops.

PSU, RAM, or CPU would be likely culprits.

How did you try to jump start it?

Seems strange that trying all that RAM in all 4 slots causes it to do the same thing....shut down. It's unusual that all 4 sticks would be bad.

That's why I'm thinking it may be the PS.

Since I don't have a spare PSU or CPU, I guess I'll go to one to see if they could help me. Don't have much money though, but hopefully it won't be expensive.

I'm thinking it may be the PSU also, but why does it stay on when the RAM isn't installed but shuts off when it's installed? That's what has me puzzled.

Also, here's how you "Jump Start" a PSU. Worked last time my PSU wanted to act up and helped my computer to POST and diagnose the real problem I had, the CPU heatsink/fan(CPU was overheating because of loose fan).

OK. I've used that before to TS a PSU.
(BTW, even though mine started with this jump method, it was still bad. The jump start doesn't mean the PS is not bad, but that's just one of the TS steps.)


If you can't jump start your PS, that's definately one of your problems. Hopefully, the only one.
 
Well now that we know you've tried ALL slots, with ALL sticks - one-at-a-time...then we either have:

All bad slots (that's pretty doubtful)
All bad RAM (also doubtful) - but you have a 680i with that lovely reputation with RAM. I say if you can either:

A) Have your RAM sticks, individually Memtested by someone else or
B) Use an alternative set of RAM sticks. I'm pretty sure a shop has a set lying around.

Either way, you can come to your conclusion quickly, but right now it's either or if you don't do one or the other.

*The other alternative is trying another PSU, but whatever you can get first.
 
Thanks for the replies.

I don't have time today to go to a computer repair shop. I'll go on Monday and see if they can tell me what's wrong. I'll post back here if they can tell me what's wrong.
 
Sorry for double post, but I just wanted to UPDATE.

I fixed the problem. Turned out, all I needed to do was take out the CMOS battery and leave it out for a few minutes. I put it back in and it turned on like normal.

I hate it when the simplest thing will fix it. The local guy here in town I took it to couldn't fix it. I know I'm never going to him again. Not to mention, he doesn't deal in High End computers, only pre-built ones like HP or Dell. (Told me my PSU wasn't normal in a tone like it was weird. ie. 24-pin ATX connector.)
 
Great to hear you figured it out. Though it's odd that it came out to the CMOS...usually you remove it only if you're flashing or you just ran (and failed) a crazy OC.
