Computer won't POST until it's warmed up
My 3-4 year old computer thinks it's a car. Other than summer, it won't even POST until the CPU temperature goes to around 30-31C (which is what, 95F?). The way I've been turning the computer on is to turn the power on, go away for about 5 minutes, come back and hit the reset button. It will then usually POST and proceed.
So, does anyone have any idea what to check and/or replace? (before anyone says this...I did buy a new computer last week...so that's done already)
AMD Athlon XP 2500+, zalman al/cu heatsink
Asus A7N8X DX v2.0, bios 1.06 (1 release behind the latest)
Antec mid-tower server case with some kind of Antec power supply
2x512MB DDR 400 ram
1 IDE harddisk, 1 IDE DVD burner, 1 SATA harddisk
ATI 9600 PRO AGP 8x, modified-fanless heatsink
If it just started, you're probably looking at the first signs of a dying motherboard or CPU.
World's End Supernova
Possibly a break in a circuit somewhere? Thus, when it heats up, the metal expands and makes contact. That's probably not something you can fix, though, short of replacing the problem piece of hardware. :(
madkevin: Hee hee, I've been living with this problem ever since I built the computer, 4 years ago. I seem to have a very high pain threshold.
Ben: This sounds plausible. I guess it still boils down to me swapping pieces out in any case, but NOW I KNOW.
I once had a system that did something similar; it would never cold boot, it would only warm boot (meaning even if it was warmed up, it wouldn't post if powered off -- it had to be reset).
I can't for the life of me remember what I did though... maybe it was a motherboard or power supply replacement that fixed it eventually when I was doing routine upgrades. I'm just not sure. I always left my system on, so it wasn't a big deal, but it was a occasionally annoying: "yeah, that's just my PC... it's a little weird, just hit reset it'll be fine".
Yep. A friend of mine had this. turned out to be hairline crack(s) in the motherboard circuitry. The heat would expand the metal and then it would boot fine.

Thanks all! I don't have to waste money or time replacing the power supply. Time to hunt down an Athlon XP motherboard!
+1 rep to all of you
My computer's also acting up.. what I think is the cpu fan sometimes makes a loud, creaking, whirring sound on startup until I give it a sharp smack dead center. It's like my own little Millenium Falcon.
