new c2d system dead, please help

[imported_alexg]

System specs:

mobo - asus p5b deluxe, cpu - c2d e6600 4meg retail, ram - super talent t800 2 x 1 g, psu - ocz 700w 7000 gsxssli, gfx - bfg 8800 gts, cooler - scythe infinity

1. Built this out of the case - it's sitting on a phone book, so no mobo short.

2. Booted up fine so I began following the core duo OC guidelines at Toms Hardware. Yes, there was some minor overvolting - ram 2.15 cpu 2.4, certainly well within range of what is considered safe.

3. Gradually took CPU to 3.75 where it began to lock up running memtest 86. So I took it down to about 3.5 (iirc) and left memtest running for about 45 mins while I went to store.

4. Upon return system was off and now will not boot. When power is turned on all fans spin momentarily(HSF, PSU'GFX), then nothing. The mobo light still comes on whenever psu is attached and PSU is set to on.


OK, here's what I have tried:

1. Reset CMOS
2. Left CMOS battery out all night
3. Tried I ram only stick in all slots, tried the other stick.
4. Rebuilt system. Checked and dbl checked. All power cables hooked to vid card, main, and cpu.
5. Tested PSU with a cheap PSU testor, only 20 leads, but PSU fires up and testor light is green.
6. Examined CPU for any damage and none.
7. Examined MOBO for busted caps and none.
8. I'm pretty darn sure HSF is making good contact.
9. Tried old PCI vid card with PCIe out of system

This is my first PCIe system, with the new RAM and all that and I have no parts to switch out!

Ideas?

Ouch. My first thought on this post is that paper is an insulator and you overheated your motherboard by restricting air flow leaving it on the phone book. Also the fanless design of the chipset etc relies on your case fans for proper cooling.

To prove this plug a new powersupply into the motherboard and boot up. Your motherboard should remain on with nothing else connected.

If the motherboard remains on with no ram, HD, Vid etc. Then add each piece back one by one.

Thanks oOzo. Will try. BRB LOL! Seriously, I'm dying here. Some ohters seem to tnink I cooked the CPU but I doubt this. Seems an INTEL chip should be a little tougher than that. U think?

ok, I tried firing system up with nothing in it - no ram, no cpu, no vid, nothing and PSU came on and stayed on and then SMOKE from MOBO! Youch. Did I do something new to it or does this just confirm your MOBO hypothesis?

BTW the PSU booted up my mom's old PC so I suspect it's ok.

Yeah you definitely fried your mobo. Sorry to hear that man ... you could always try to return it DOA!
