hi there,

I've just installed the Intel e3600 cpu after replacing it with new Arctic Silver 5 Thermal paste. When I switch on the pc, I am only getting power on the mobo and ALL fans and the pc doesn't boot. I don't hear the BIOS bleep and it seems dead.

Is my CPU burnt out or something?

Please please help! 😳 🙁
 
I will double check if the CPU is orientated, although I used the ARROW in the corner to match the orientation on the mobo.

Lastly, I am getting power for DVD writer and keyboard, but the monitor doesn't switch on.
 
The cpu orientation is correct. I double-checked this with the mobo manual. I also checked if the PSU connectors were disconnected, but these are okay too.
 
This was overclocked, but I knocked it back down as I wanted to replace the old thermal paste with the new one. I took off the HSF and then took out the CPU and carefully cleaned it, making sure I don't touch the pins. I then replaced it with new arctic silver 5 paste (v.small blob spread across the head spreader).

After assembling, the above has happened.
 
Since you had it OC then changed it to default, maybe perhaps you might have over looked a setting.

Have you tried resetting the bios by jumper?

Edit:

BTW was that a typo on the type of CPU you have? Is it a E6300 not E3600?

Edit:

:lol: I had typo's on my comments.
 
@ Grimmy - no mate, I haven't tried resetting the mobo jumper. Don't know how to do it, but will look at the Asus P5B (Standard) manual. If anyone knows how its done, please let me know.

Thank You
 
The manual should definitely tell you how to reset it. You should put the time and date back once you get it started back up.

There should be jumpers near where the cmos battery sits. Basically you just put the jumper on certain pins to cut power to the cmos or bios chip which erases any remembered config settings done to the bios.

My dad's new build doesn't have a jumper, but actually a button to reset the bios, so not all MB are the same.
 
okay tried resetting the CMOS. This hasn't made a difference though and the pc still powers up, but nothing else. Don't know what to do... :?
 
the cables and everthing are fine mate.

I thought that the best way to solve a problem to do with heat issue is to remove the cpu and clean it.

So what does it sound like? video, ram, cpu or mobo?
 
Are the socket pins okay? Check it again. You might be one of the few that managed to damage the socket pins on the motherboard while installing the cpu.

Next time, try not to remove the CPU from the socket when cleaning the old thermal compound. You can clean the cpu as it is attached to the mobo. Don't worry about the compounds that gets stuck in the sides. It won't harm the cpu.

I have replaced my AS5 several times since I assemble my current rig last Oct 2005 and never I have to remove the cpu unless I don't need it in that motherboard anymore.

Well so now all you can do is verify if it's the cpu or the other components that is causing the problem. I'm sure you still have to warranty on the E6300.
 
I kinda fear the socket pins may have been bent. There really shouldn't be a reason for it not to boot up now, if it was fine before you took it apart to just reapply the AS5.

I'd re-check the socket to make sure all the pins are aligned properly.

It's actually kind of a fear I had when I built my dad's PC. Heh, when I was inspecting the MB, looking at the pins, I kept thinking to myself, man, what would I do if one or more of them pins get bent? 8O

Edit: :lol: . o O (guess I'm not the only one thinking about the pins)
 
Since you guys have reminded me, I did notice a few pins that are bent...i thought maybe some of these being bent is normal...does anyone have a pic of pins which should be bent?

thanks
 
Ummm.. errr.. none should be bent. If there's a pin, it should be straight. :lol:

Edit:

You know, kind of think of it.. I been trying to help folks on the home built sections on some C2D that don't boot up. I kinda wonder now about them.

Perhaps the socket pins, if bent, would be a certain/important thing to easy over look.
 
Find the pins, short with a jumper, power up the system, spull the jumper off, reset Date and time in the Bios.

oh NOOOOOOOOOO! 😱

Don't do THIS. Never reset the CMOS jumper pin and power up without first removing the pin.

1) Remove the power cord;
2) Remove the battery;
3) Set the jumper to reset CMOS;
4) Wait . . . . . typically 20 seconds or so;
5) REMOVE THE JUMPER;
6) Replace the battery;
7) Reconnect power cord; and
8) Power up the box.

Had another thought, if you do have some bent pins, I recall a certain trick that is done on CPU pins that still could be done perhaps on the MB socket pins for the 775.

Try using those pencil that you put lead in. I just remembered I had a .5 mm pencil, took the lead out of it, and found my old P4 2.66 CPU. With the lead out of the pencil, the top of it fits good over the pin, so I think you might be in luck to try that trick on the bent pins in the socket.

@ wisecracker - I just followed the mobo manual, which says that I:-

1. take out battery
2. move jumper from 1-2 pins to 2-3 for 10 seconds
3. now replace back to 1-2 pins
4. replace battery
5. switch on pc


I have taken 2 photos of the CPU pins that I'm suspicious about:-

What do you guys make of it? Can someone double check it on their 775 mobo please?
 
Agreed. That was a nice pic of the socket. I can see 2 bent pins on that.

Though, I don't think it would be wise just to take my dad's system apart for a pic.

I did find this pic though, which shows the pins themselves:

775 pins

and here's another:

775 socket
 
are you guys 100% sure that there should be no bent pins?? I remember one of the pins being bent, yet the cpu was still working.
 
I'm pretty sure, sorry to say.

When I put my dad system together, I pretty much eyed different angles to see if any pins were misaligned. And all I recall is that I had very straight rows of pins.

Since your system was working, maybe that one pin wasn't bent enough to cause a problem. But seeing those 2 being bent, I'd have to say we are staring at the exact reason why it won't post.

Try using the pencil trick I mentioned.

Ok grimmy mate, I will give it a try, although I'm not too keen on it. What if that isn't the problem and I end up burning out the CPU or mobo?
 
All I can recommend is to try the best you can. If you do problem in not getting it straight, then I'd recommend to get an RMA on that MB.

If you can't get them straight, don't attempt to try to run it. Very hard to say what you could end up frying.
 
If the board came with a bent pin then it should have been returned right away.

I didn't realise that this was abnormal and also if the CPU worked fine, I assumed there was nothing wrong with the board.
