Kids computer.........heatsink/fan became loud, it's running tho....computer turns on, system will not boot, and nothing comes up on the monitor (although there is power to the monitor). I'm thinking processor fried or something. It's an HP about 2 years old. Can't boot from cd. When power is turned on, I see the cd/dvd lights, hard drive light.......but it just sits there with the heatsink fan going and that's it....

Some bios'es are set to detect the cpu fan and if the fan isn't running right, it won't boot to prevent the cpu from frying. can't say for sure that this could be your issue but should be checked out. Also, if it's an older pc the power supply may be weak because they deteriorate with time. Might have enough amps to run things but not boot the pc up....or worst case scenario, the power supply is going bad and took the mother board with it. I've seen bad modems prevent a pc from booting too. The best dianostic advise would be to pull the board out of the case, remove everything except the video, cpu/heatsink/fan and one stick of memory and see if it will post (Power On Self Test) that the black and white screen you'll see when you first turn it on

the heatsink is probably o.k. just replace the fan...there usually 50 or 60 mm fans and less than $10. I would think

Found a processor and fan, Joe ---- brand new still in OEM box for $87. The processor presently in there is a Celeron 341 2.9GHz ......I'm getting the fastest one made for this mobo --- Celeron 356 3.3 GHz.. ;D

....Still no boot. No hard drive activity. I traded out memory (with known good memory), installed new processor, hooked up another hard drive. It powers up, processor fires up, cd lights go, gets to hard drive and nothing, no beeps, nothing on monitor..................dammit.

I'd try a different power supply also. In my opinion mobo's fry much more often than cpu's

The computer starts up, just doesn't make it to HD boot. I would try a different power supply to rule that out as it is an easy swap if you have a spare one around. Seeing as you said you didn't get any video output I would suspect the either the northbridge or southbridge of the chipset has failed.

And this thing has onboard graphics. Unfortunately I don't have a spare power supply available. I'm tempted to just scrap it.......keep the hard drive. I've toyed with the idea of putting in a new MOBO in it. Since it's an HP computer, that might be a chore. Thanks for your input Joe and Web P. Much appreciated.

A lot of the HP's and comcraps use what they call a "mini" power supply, mostly because that's the only thing that can fit, a standard size will never work, The nice thing about the mini's is that they are really cheap! www.newegg.com/Product/Product.aspx?Item=N82E16817338031You'll need to check the physical size in order to determine if it a mini or not Another cheap option, go to your local pc store, pick up a psu above the watts you now have and, you can leave the psu outside of the case, just connect the 20/24 pin connector to the motherboard and 4 pin cpu power connector if you have one No need to connect anything else except the keyboard and mouse, .If it posts then keep it and be happy, and install if it'll fit, if it doesn't post then return it to the store and plan on getting the kids another used pc, if it posts but will not fit in the case then order the one from newegg (That's a real good reason to tell your wife that you need a new pc so the kids can have your old one)
