I have a little bit of a headscratcher here.

I've been running the following system for a while now, with few problems:
GA-p35-ds3r
e6420 @ ~3.2
2gb Ballistix 1066 (Had to be rma'd in the last 4 months due to instability)
eVGA 7950 GT
Corsair HX620 psu
Adaptec 29160 Scsi card
Seagate cheetah
WD 320gb
2x optical

Other than needing to RMA the ballistix for a new set sort of recently, everything has been stable, cool, and hassle-free up until the last couple of days here.

I'm a college student at the moment and I made the drive home for thanksgiving break, pc in tow. Everything was fine before I left and everything seemed fine for the first few days of break. Then two days ago when I powered on the PC, my keyboard and mouse didn't get power and there was no picture on the screen. PC was on, fans spinning, HDDs spun up, etc but no picture and no response to keyboard input. So I hit the power button and tried it again: This time everything was normal, keyboard and mouse lit up and post info on the screen. Checked the bios and everything was normal. Tried rebooting a few more times and all subsequent attempts worked. booted into windows and ran some orthos & etc. played some games... everything stable and normal so I chalked it up to a fluke. The next day, I turn the thing on again and it's a carbon copy of the above. After sitting for a little while in the non-posting state, I hit the power button and try booting it again and it starts up just fine. Now I'm starting to get worried, but can't think of what could be wrong. I determine that Ill figure it out on Friday when I wake up.

Fast forward to Friday and it once again sits there in its non-posting state, except this time I can't get it to post no matter what I seem to do. I've tried most all of the standard troubleshooting arsenal short of doing a full rebuild of the PC which I will end up doing if no one has any ideas. I hooked up an old case speaker to the mobo to see if it gave any useful post codes, but it always just happily beeps once no matter what is installed.

So i'm pretty much stumped. I would love to hear any ideas if anyone has any. I'm sort of thinking its the mobo, but im not quite ready to run out and buy a new one just yet.
 
Either something needs to warm up before it makes all the contacts or a component is on the way out.

Possibly dust working its way into a socket somewhere, strip the PC down, clean and rebuild it.
If that fails, borrow a PSU (thats known good and powerful enough) and see if that sorts it.
Powering up issues are the earmark of a fatigued PSU.
 
Thanks for the tips.

Unfortunately no luck on my rebuild. PSU, graphics, and mem all tested working and functional using this spare pc im typing on. Looks like i'm heading to a B&M to buy a new mobo and see if that fixes it. :(

I wish I could order one online but I have to have this running by Monday. Hopefully I don't get gauged too much. :\
 
Did you try parts from the machine you are typing on in the faulty machine?
It may be components that dont like each other rather than an outright fault.
Worth trying as it might save you some cash.
