Solve : Installing my other two sticks of RAM after installing Windows 7 now no POST? |
|
Answer» Howdy If it works with one then why would adding 2 more kill the psu If there was a big enough load on the 3.3 volt rail, adding 2 more sticks would over draw the supply easy. Especially if a more graphics intensive OS is being used because more power is required from the graphics card and the voltage rails cannot deliver their full potential if one or more other rails are maxed out...This would be even more so if the psu is FAILING. That's why I asked about his specs. and how old the computer is. And to top it off, I said the psu is a suspect, I didn't say it IS the problem hold a SEC.. kenter Quote from: Kenter on December 18, 2009, 07:58:40 PM That's what I thought, though it has been working for like two weeks now with XP. Initially this info. would have been helpful I would try to borrow another psu, if that is not the problem, then poo on me EEVIAC: Sorry about that looks like I'll have to make a trip to town tomorrow to get a PSU because I don't have another one to test it. It has a 400w in there now so what kind of wattage should I look for now?Before you do that, could you give the make/model of the PSU you are using now.. edit: Also, I'm a little skeptical about sending you off to the store before we're sure about what the deal is.. Do you by any chance have or can you borrow a multimeter so you can test your existing psu? If you do, but don't know how to USE it, I can help you. Quote from: Kenter on December 18, 2009, 07:58:40 PM ... I bought the MOBO used off of eBay and it hasn't had a problem for like 2 to 3 weeks now...That explains everything. Quote That explains everything. I still have my bets on the psu or a couple of other things. The ram voltage or speed may not be set correctly in cmos or, according to the ASUS, QVL (qualified vender list) for supported memory, OCZ is not on there list, however, why a single module would work and not the other 2 is wierd so QVL may not be a factor here. I guess before testing the psu we could try this... Remove the other two ram modules to allow yourself to enter cmos setup.. Enter the Advanced Chipset Configuration and try some different voltages/speed on the memory and remember to SAVE your settings before exiting AND MAKE ONLY ONE CHANGE AT A TIME, for testing. We don't won't to get too confused here. Once you exit, if it boots up, shut down the computer and put the other two RAM modules back in to see if the new voltage settings work. If you cannot boot after setting, remove the battery and start over by going back into cmos and trying a different setting.. If none of these other settings work, then we need to test the psu, somehow.. If you cannot borrow another psu, maybe you can take your psu and put it into another computer, if someone doesn't mind. If it works then my bet is that the problem is not the psu, and more likely to be either a defective board as Commando said, or a QVL issue... My bet is incompatible RAM... Quote from: EEVIAC on December 19, 2009, 04:18:52 PM I still have my bets on the psu or a couple of other things.I'm sorry, on the ASUS web site I was looking at support for A7N8X Deleux Your board is A7N8X-E and didn't see any memory QVL for that board, but memory compatibility could still be an issue and the psu could still be an issue.. But ok, you can't get into cmos at all so we'll just work with what we can... But let's back up a little, why did you buy the motherboard in the first place? What happened with your system before that prompted you to get that board? What symptoms was your computer displaying? I should have asked this a long time ago... EEVIAC: Well it goes like this I had the same board in the same pc about a month ago the capacitors blew up in it and started leaking. So ever since then I had been debating on replacing the MOBO or converting over to a Mac G4 but I couldn't bring myself to do that so I bought this MOBO. Like I said I bought this one about two weeks ago and was running XP but then I remember either Steve Balmer or Bill Gates saying on the net or news somewhere that "Those who continue to use XP will be severly punished" (Don't qoute me I dont remember if those are the exact words or whatever). So I bought Windows 7 and it is awesome I used the Windows 7 beta on my laptop when it was big and I tell you what! It is the new XP!! IMHO. Anyhow that's the history of my super computer lol! Quote I had the same board in the same pc about a month ago the capacitors blew up in it and started leaking. Your psu might have caused this. Too much PSU "ripple" has been known to cause capacitors to break down.. Low-end or cheap power supplies would have a "ripple" percentage of more than 1 %. The bad caps. on your old board indicate possibly a bad psu, which you continue to use with your new board. But don't go to the store yet... Tell me what the make/model of your PSU is... |
