OT: Did I Fry My CPU?

[WmAx]

A while back I accidentally plugged a 12VDC PS into the mouse or keyboard port[the PS has a PS/2 connector like a keyboard and mouse use] and the computer will not boot up or do anything after this event. The PS of the computer is still good, and I tried another PS just in case. I was hoping the motherboard was the culprit[Intel D865GLC] and I bought a used replacement board for cheap, but when I just tried the new board, still nothing. By 'nothing', I mean that no fans on the board or chassis start up, no HD booting, etc.. Does this sound like the CPU was fried? The CPU is a socket 478 2.8Ghz P4. I guess the RAM is probably fried as well?

That would be a dead processor. If just the RAM was dead (it may or may not be), your computer would probably be able to POST, but hang at the memory test and give you a bunch of error beeps. I had this issue before (where NOTHING happens). I replaced the processor and it worked fine. Good luck with your system!

 

[ducker]

Even with out a CPU in your board it should start up and BEEP at you.
Are you sure you reconnected a DIFFERENT power supply to the alternate board correctly?

You might of damage quite a bit.
CPU, MB, memory, possibly expansion cards like sound and video as well.

But with out a working Motherboard it's hard to figure out what's salvageable.
<edit>
Hm I think I've had that happen before... just nothing... taking out the CPU should get at leat BEEPS and no posting.

 

[Methost]

They are right, Try taking the CPU out of the motherboard. You should get power to your fans and also a couple of beeps. If you do not, you have a problem other then your CPU. (Though your CPU may still be damaged)

 

[WmAx]

You two were right, it's not the CPU. I just came back from a computer tech and he tested the CPU, RAM and PS on another board and it worked fine. The replacement board appears to be dead -- just like the original. Ack!

Ohh, DOA mobo...that's always a treat

 

[Sheep]

You think thats bad? My stupid Volcano 12 heatisnk has a clip that you have to bend around the base of the processor. The screw driver slipped out of the little footing and I stabbed my computer, right in the motherboard

You know why this happened? I was putting AS5 on my CPU as the ppl who made my computer put NOTHING on, no heat pad, no crappy paste, nothing.

I break it trying to help it....BAH!

I might have another board you can have. Just now to remember where its at.
Hmm, also I don't recall which socket that Intel board is.
I will check, if you want?

Edit::If I recall there is a P4 1.7Ghz on it now, just can't remember what socket type.
Let me know if you need me to check on it. It does work fine, was pulled from a working computer.
It also has 4 sticks of RDRAM 800. (I think 2 sticks of 256 and 2 128's)

I don't recognize the 'C' at the end of D865GLC, but D865G and GL boards are socket 478.

Sure, do check, I would certianly appreciate a working board. The board I have now is a socket 478.

Sorry MDS, not being snooty.
But - Yeah I noticed that he said socket 478 on his first post

I was just wondering has he now already gone the route of getting another board.
And if not, then would he want me to look for this board and see if its a 423 or 478.
I would mainly just charge shipping.
Let me know WM.

EDIT:: You posted while I was typing. I will now go look for it. (yes I'm lazy)
EDIT #2:: Nope sorry. I was wrong its a P4 1.4Ghz and too bad its a 423.
However the memory is good, I guess I will sell all on eBay. (sorry Dave I have to)
The memory I was correct. RDRAM 2 Samsung 800Mhz 256's & 2 Samsung 800Mhz 128's.
I went ahead and pulled the HSF, so I could check the CPU speed.

I purchased a temporary board ($30 used) at the local tech shop. However, it's unusable, as the built in video is horrid[fuzzy at high resolution on my Trinitron FD 21"] to the point of being painful to my eyes[I should note that I am very particular about picture quality on a computer monitor, so what bothers me might be considered okay by someone else]. It is an Asus P4P800MX. No AGP slot, so I can't pop one of my extra video cards on it. I am suprised the video is so bad, because the D865GLC Intel board has the same integrated video Intel Extreme 2 chipset, but the Intel was flawless in video quality. This is no small difference, either. This is a matter of perfectly sharp edges vs. badly blurred ones at high resolution settings. I guess this comes down to vendor implementation/competance. I did some Googling and found several complaints concerning the Asus board integrated video being not so clear. I had the same problem with many older integrated video systems on boards, but I assumed that this issue was a thing of the past. I guess the Intel board simply had unusually excellent implementation, thus causing me to expect the same level of performance from Asus. How wrong I was! Argh! I returned the replacement Intel D865GLC board today, as it has a 30 day seller warranty. I suppose I'll have to wait for a replacement[unless the seller decides to refund instead] to arrive. Thank you everyone for the help you provided.

Pesonally I would never use 'on board' graphics. Except on a laptop. You could have looked for a cheap PCI grapics card (would be 10+ times better, and only cost under 20). But a replacement mobo that has a AGP would be much better IMO. Nah, I don't keep extra PCI graphic cards anymore. And I only had 1 (now that one, would be almost impossible to find, I have absolutely no clue where I put it), and it was used mainly for testing. I really should pick up another one. (for testing only) I do have plenty of spare AGP's And some fast ones.

Sorry I couldn't be of much help.
Maybe next time, but then again - Hopefully there is no next time

I have never used on-board graphics before, except to see how bad they were. . However, the Intel D865GLC board had virtually 'perfect' image quality. I was ready to put in an AGP card when I first started using the board, but the image quality was flawless[At 1600x1200 on a high quality 21" graphics monitor], giving me no valid excuse to put in a card. I should note that I do not play 3D games; so that aspect is not a consideration for me.

I'm going to guess that brian is a gamer and has spent several hundred dollars on a graphics card. Games are the only thing that truly stress the video subsystem. Gamers tend to frown on integrated graphics and for good reason - they suck for 3D and especially for modern games.

On board graphics however are absolutely fine for any 2D application and limited 3D. I think you just got unlucky WmAx and got a bad motherboard.

Nah, not really. I do about 2% gaming, 90% Surfing, and 8% DVD, music, etc..
But yeah, I got the power when I need it. I don't by chance play weak games.
So yes, when I do play, I want seemless game play. As well as seemless DVD watching.

I may actually even be selling my current setup, to go one notch higher.
I used to really get into 'overclocking' but that was a thing I did from age 14 to 24.
I would never really care to do it anymore, but I will do a benchmark (and or 4+) to make sure the system was built just right. (Dave can attest to that)

Yeah, for the most part its just nice to know you have the extra oomph when its needed.
For Far Cry, Doom 3, Half Life 2, etc...

I get back into games on blue moons. At the moment I play UT2K4 about every other week.
(For about 2-3 hours)

Hmm, that is unless I could talk one of you guys into a personal match or 2

EDIT:: However, I am assuming you saw THIS So its not like you were going out on a limb

I must be REALLY unlucky then, because in the past every integrated video system I have tried [with the exception of the D865GLC board] started to look fuzzy starting at 1280x1024 when used on a very high quality 21" graphics monitor. The problem would be hard to notice on a standard quality 17" monitor at 800x600 or 1024x768. At 1600x1200 on a high quality 21" graphic monitor, the integrated video experiences I have had have been simply bad[exception being that last Intel board I had]. I have not tried a huge number of boards or anything, so my results may not apply to others. Maybe perfect high resolution output to a high quality graphics monitor is typical on most integrated video systems; but this is not verified in my unfortunate experiences.

Its funny, most of the time the CPU is bottle-necking the graphics card. I have a 9800pro thats overclocked. If I got a 64bit(socket A right now) system and use this card, the performance would be way better. Even some low end 64bit CPU's bottle-neck graphics cards.

I recieved and installed the replacement for the used D865GLC board today. This unit also does not work. This is the 1st time I've ever had a P.I.A. ebay purchase. But I blame myself: I should have never purchased something as fragile as a motherboard as a used item. I'll try to get a refund[though I am out the money[approx. $20] for shipping 3 times[1st purchase, sending back 1st time, sending back 2nd time] and the restocking fee[$10] I was charged to return the used Asus motherboard to the computer tech shop plus $5 for a heatsink bracket[the latest replacement did not have one]. In hindsight, I ended up throwing away approx. $35[this is presuming that the seller will refund the $45 for the board, otherwise my total wasted value will be approx. $80] by attempting to save $50 by purchasing a used board on ebay. Funny, eh? Now, who wants to suggest a new board that supports FSB800Mhz, 2.8GHZ, P4 Socket 478 CPU and PC3200 RAM?

If you like reliability, I would stick with the intel boards, maybe this: http://www.intel.com/design/motherbd/bz/index.htm
