First Time Boot Up

Just Bought a PC Kit to build myself a New PC. I've built several in the past and I thought This time would be no different.

First time I booted up the PC the power come on for a couple of seconds and then went off again. I tried switching it on a few more times and the same thing happend.

On Checking that I'd plugged everything in correctly I discoved that I had attached the fan on the CPU the wrong way round. This meant that the heat componed on the bottom of the fan was not touching the top of the chip instead the metal part was touching.

On turning the fan the right way round the PC now Powers up but I'm getting NO output to the Monitor.

Could I have damaged the Chip by installing the Fan the wrong way round. If so could this also have caused damage to the Motherboard.

Thanks in advance for your Help.

The reversed heatsink shouldn't have necessarily been a problem as a short circuit. It could have created a problem as far as a heat problem.

Do you get a single beep when you boot the computer? Try reseating the video card. Usually, the PCI slot next to the video card shares resources with the AGP slot.

 

I'm not getting any response from the PC ie. Beeps.

The graphics is Internal to the Motherboard. I tried adding a Graphics Card and still got no Output to the Monitor

Any Ideas

Try a "minimal boot ":
Disconnect all drives, take out all the (PCI/ISA) cards, dicsconnect any periferals, etc.
Just have motherboard, CPU, (video[onboard]), RAM and Power Supply.
If you have more than one stick of RAM just use one stick.

If it POSTs then add one component at a time till the system is running.

...and keep your fingers crossed it's not the CPU.

PS. Reply back if this dosen't work, could try clearing the CMOS and building it outside the case.

 

Flossie:
I doubt very much that you have damaged the processor. You should start with nothing in the machine (card-wise) other than video - no audio card, no modem, no NIC. Three things to check very carefully - memory & video seating, cabling, and anything you are plugging in - mouse, keyboard, monitor. Upon first start, to be real cautious - go to the BIOS and set it for default or "Setup ". If nothing - notta, notta - clear CMOS - unplug ATX power connector, move the jumper to 2&3 then back to 1&2, reconnect Power and then reboot - right into bIOS and "setup ".
Because you are onboard video and also going with a video card - make sure your BIOS and any jumpers relative to this are set correctly.

 

Could using the Wrong Power Supply cause this problem. I'm using a 350W PSU but I've just discovered that maybe I should be using a 300W PSU.

Just seen a System on the Net using the same Motherboard and CPU that I'm using but it uses a 300W PSU.

Would this Cause the problems that I'm having.

 

You should review all your connections. Example if your floppy is connected wrong, like the power pins are connected backwards or incorrectly (like one over). What you discribed will exactly occur!

 

Just to answer this question. A 350W PSU should run the system more easily than a 300W. Can't have too much, just not enough.
Problems that could occur though are if the PSU is faulty and not supplying the correct voltages (this can be tested with a meter) or if you are using a PSU from branded system like Hewlett Packard (for instance) where the power leads don't match up with the connectors on a standard board.

Just to let you all know I still havn't solved the problem. I had someone look at it and they suggested sending it back to the Company I bought It from

Thanks for all your help

OK, whats the motherboard, whats the CPU, whats the memory?
Lets start with that information and maybe there's hope. Did you ever clear CMOS as i suggested earlier?

 

Just to let you all know. I returned the Motherboard to the Company I bought it from and it was faulty. A new one is in the post to me.

Thanks to everyone who Helped.
