Cold boot problems...

Hi all,

I've been getting issues with cold booting. I need to cycle power several times before a post. Once posted the system is solid and even if I manage to get a little OC on to stay it is still solid - Prime95 for a few hours no probs, temps also okay.

It all began when I put a Q6600 into my system instead of an E6600. Saying that I could only get the E6600 to about 3Ghz before would not boot. I am pretty convinced the mobo is the root cause as I tried with different RAM and while not tried the CPU in a different mobo thinking it would either work or not. BIOS are the latest and I also flashed them once more after the installing the Q6600.

Also I sometimes get choppiness in all games without apparent reason and also sometimes the OS itself becomes very slow with the cursor jiterring when moved and all the menus.


Specs:

Q6600 @ stock
3x1GB Corsair Value 667 C5
ASUS P5B
GTX 260 @ stock
Corsair 450 VX

Can anyone issue advice as to what can be done other than a new mobo?
 
not sure if its the issue, but why are you running 3x1GB sticks of ram in your system?
 
To mention it - yes there does seem more of a problem with 3 sticks and with 4 you can forget it. Seems like the mobo can't take more than 3 sticks. Tried with different RAM as well.

Although 2 or 3 sticks or even 1 still has the cold boot issue, or any boot issue to be exact as the computer does not restart either - need to cycle power a few times too.
 
Could be a mobo issue, but since it began when you switched out the CPU I'd also throw in a PSU issue. Only time I've had a issue like that was when I added a Video Card in a crappy HP built PC where the PSU was not able to give it enough juice. It worked fine if I could get it to post, but had a bitch of a time getting it past post. Sometimes it would start immediately, other times it took a couple power on/off's, other times it would take hours of trying and hoping I got lucky.

If you have another PSU (preferably one more powerful) you could try that and eliminate that as the cause.
 
As much as I don't want to think that, I do have a 550VX. Will be a PITA as it's currently in another computer!
 
On one hand you say the computer is rock solid stable once it boots, then in the other hand you're saying it experiences some issues occasionally that are mostly unexplained.

So which is it?

As for the issue with no wanting to boot with 4 RAM sticks installed, this is usually because you have to bump the voltages when using all four slots.
 
Yeah confusing - so when stress testing, nothing weird happens, but then I did get these choppy moments sometimes. I've reinstalled windows now and the rare choppiness problems seem gone fingers crossed.

Also did not mention - BIOS tends to lose any settings I put in after shutdown or restart. It's about 1 out of 50 times that it actually keeps anything - even ignoring the CPU fan. CMOS battery has been changed but did not change anything. Also for voltages - I tried max for RAM @ 2.1 or 2.05 and it does not seem to make a difference as to whether settings are retained or whether it boots.
 
Well if the BIOS wont hold it's settings then it's a good bet that it's a motherboard issue.
 
Yeah seemed that way all along, just wondered if there was any solution at all apart from a new one as don't have any places to get it - looking for about £20-£30.
