My comp won't boot on this morning ;(

[Jjoshua2]

I got up this morning and my comp won't turn on. The lights and fans come on, and then the three lights on the keyboard come on, and then nothing happens. The fans stay going fast, and I think they are supposed to slow down a little bit after the initial boot up. It's not beeping, but I can't remember that it normally does. It is an asus P965 mobo. The monitor never gets any signal. Yesterday, when I was leaving for work my computer wouldn't turn on either, but it blue-screened at windows login. I think when I tried it again though it didn't get that far. I think it was because I just installed A^2. So I put it to last good boot when I got home last night and it worked fine.

I am hoping it will boot up better tonight, because it seems like it might have had the same trouble yesterday morning, I can't remember. Any ideas on what to do? I guess reset the CMOS is first step. My setup is overclocked but has been stable for like a year. It is summer though, and I don't have aircondition, but I used to run prime95 or llr or other intensive stuff, and I haven't since summer started. Maybe the cpu has been getting too much voltage because there is no vdroop anymore? I had to set the voltage pretty high, because of all the vdroop when all 4 cores were going. I can't remember anymore what it was set to.

Ok, so I p5b-e and I shut the power down with the psu switch and back, and now it boots on. It has also been about an hour since I tried it last, so maybe that might have something to do with it. I should say that my computer automatically boots on at 7, so it had been trying to turn on for a few hours before I got up and looked at it, since I slept in. It was on with no video apparently doing nothing when I first saw it. I would like to fix this problem. Any ideas while it is apparently working?

Definitely reset cmos and eliminate the overclock. Once that's been ruled out you can determine if any actual damage was done to your components or you just simply became unstable.

Edit: new info, don't fully understand what's going on and too tired to read.

I'd also reset cmos. Reset CPU to stock specs.

What concerns me is you say you're not seeing any video. Can you be more specific? Do you see video during the post and then you go to a blank black screen during the windows load?

If you don't see the post, then test your vid card to verify that it's working. Let's eliminate it from the mix. If it tests good, and you're positive that your cpu is good (test it too, if you have questions), it would suggest you have a motherboard issue.

If you see the post and your screen goes black during your windows load, then you have a corrupted windows install. This would be a common issue during extremely hot temperatures. Overclocking compounds this hot weather issue.

Give us more details of your issues.

I didn't see the post. I never saw anything. But like I said it is working right now, since I turned the power off the psu and back on and tried again it worked perfect first time. What bothers me is I think this has happened before, and I don't want it to happen again. I have a bit of money, so I could upgrade a component or two maybe.

What are your system specs including your OS. Be sure you post your brand and model PSU. Let's get everything on the table before we spend any money. We want to be sure any money spent will actually be spent resolving your issue.

Good tip....



If I were you, I would put everything back to default specs and run some tests. If your problem exists and with everything running at stock, then it would sound like more of a driver problem.

I have Vista X64 ultimate and a corsair 520 w/ the removable plugs. I have a 8800gts and a q6600 and a couple hard drives. I think my corsair psu should have plenty of juice to boot it up. I've never had any issues while gaming really, and that would use way more juice. The problem is that the problem is quite intermittent. It has only happened a couple times. So if I stop overclocking I won't know if I've fixed it or not unless I wait a month or two. If it happens one more time this month though, I probably will. I don't think it could be drivers, because I didn't even see it post. It was way before drivers would get loaded. I could update my bios perhaps, but I looked a month or two ago and the new ones said they just supported new cpus I think, but maybe there are small bugfixes.

*What motherboard are you running? Some motherboards have difficulty supplying enough power to a quad core. Is yours a 125 watt processor? If so, have other users had trouble with the same board when using a 125 watt processor? Have you tested your ram?

*Keep in mind that higher ambient temperatures + over-volting + over-clocking can cause a motherboard to become unstable. Could this be your issue? It would explain why things ran fine during the cooler months of the year.

*Something else to look at ... check your capacitors. Especially the ones around your CPU. Bad caps are well known for causing unstable motherboard situations. Look for slightly burnt, discolored or swollen caps, or ooze leaked onto the motherboard. If any of those exist, it would explain your issues. Over-volting can cause caps to be pushed past their limits. Your board may run for a while with bad caps, but the voltage control is compromised. Eventually, they "puke" and will likely take your CPU and possibly other components with them.

*Your bios update idea has merit. It might have some bug fixes, and not just updates for newer CPUs.


Just some starting points to consider ....

Edit: You said the problem is quite intermittent. Does that mean it has only happened on the hottest days?
