Noob Needs Help

[fb0252]

I'm on my 2d MB from New Egg, Asus P5E. Computer Tech upstairs determined 1st that 3 of 8 functions dead, so RMA.

Now, second board arrives, and I take extreme care.

Put MB on its anti static sheet on cardboard box, installed memory, video card, and cpu, plugged on monitor and keyboard, connected 8 pin and 24 pin power cable, and power button connector. (no CPU fan connected, and without heat sink.)

turned system on and got the Asus welcome screen, and invitation for bios pop. left system on 60 seconds, 90 seconds at most and pushed power button on case to turn it off.

second boot I got black screen. I then installed heat sink and CPU fan connected. got black screen with all subsequent boots. zero video now.

would someone mind telling me where I have gone wrong here.

6850 core duo
Asus P5E
2GB Cosair Dominator DDR2 800 3-4-3-9
2 x 150 gb raptors

Why would you do that? Did you monitor temperatures in bios during the whole minute you tried to run a highly-clocked quad-core ambiently? That was a bad decision. Very worst case- for some reason if you got an oem chip with no hsf, and wanted to see if it works, lay something on it to spread heat, and only wait till you hear post speaker. That'd be too much in my opinion.
Re-seat the processor, maybe borrow a s775 processor from someone (and be damn sure you don't tell them about what you did, and certainly don't repeat it again, let alone with another's chip) to see that the problem is contained to the processor. If it is- you wasted some good silicon, and I'd just buy a dell...

guess your saying you can fry the processor (core duo) in 60 seconds. i noted it was quite hot to the touch after the one min. BUT, i thought the core duos shut themselves off when overheated??? (i did not monitor bios or bios temps. just sat there thanking the good lord for the boot.)

I would try a run with a different process like suggested above but never ever run any processor with out hsf on it -- not meaning to bash but that isn't ever a good move. C2D do shut down but we're talking about 100c department

thats your 1 major variable - get a cheap s775...borrow one... maybe an e4xxx and give that a go

also whats your video ? that is a slight possible issue that should be taken into account. Get a pci vid card or 2nd pci-e if available if the processor doesn't seem to do the trick. Also make sure you're giving that ram the proper amount of voltage needed, as it might not post either

Throttling is a feature on the core2 architecture, yes. However, it assumes dropping voltages and multipliers will work because a pre-defined threshold was reached. In this case, there is practically no cooling, so the threshold for failure may be even lower than that reached by throttling. There is a good chance it can still "fry."

But if your processor was ruined, you'd have post error codes that would let you know. I'm not sure what type your board gives off, but if it has an LCD near the end of the board around the SATA ports or PCI slots, and it stops on a code, or flashes a couple different ones, look it up- it might give you some direction to go on if there is a hardware failure.
If you don't have a small read-out, then connect a post speaker and it should give error code beeps- which may be looked up online or in the manual.

txs very much. may I bother with one more q. what puzzles me is that the video was working fine when I shut off the power button, then nothing when i turned it back on a moment later. this is exactly the same thing that happened with my first Asus P5E that was RMA. assuming the processor did not self destruct after the shut off, and the video card works (unable to think anything happened to the video card over the short period of shut off), i notice neither comment suggested anything with resetting the CMOS. i'm only somewhat familiar with CMOS, and am wondering if this is at all relevant on these symptoms?

Definitely try resetting the CMOS. However, I also feel that you fried your CPU. I bet the (static) display would stay on until you shut off the power, even with the CPU fried, since the image is already in the graphics card's video memory. Might I suggest that you sit down and read the installation manual(s) first before making another attempt?

This is why Intel CPUs say on the box "To be professionally installed".
