VAIO pcv rs 430g will not boot up.

January 22, 2011 at 14:00:04
Specs: Windows XP home edition , ?
My VAIO is restarting itself after the Pentium logo shows on screen. Replaced the power supply
Could a bad CPU cause the problem? It's making a loud noise
If I upgrade the CPU, do I also need to upgrade the motherboard?

If the CPU was bad, your wouldn't even see the Pentium logo on the screen. It could be overheating though. Did you open the case?

Yes. Took off the case and cleaned out the dust. Just thought it might be the CPU cause of the noise it's making. The power supply, hard drive and memory has all been upgraded over the last 2 years.

CPUs don't make noise. Could it be the cooling fan is bad?

I replaced both fans when I upgraded the the other things. Is there supposed to be some kind of gel/adhesive stuff where the fan touches the CPU? Funny, 2 days before it started restarting itself, I was talking to someone about upgrading the motherboard, CPU, DVD burner (it died) and video/graphics cars. PC is getting older and I've got quite a bit invested in the new hard drives. I guess the fan and power supply could gotten bad on me.

If you remove and replace the CPU fan you MUST remove the old thermal compound from the mating surface on the CPU and the old fan if you are reusing it. SOME CPU fans (factory original types) come with preapplied thermal compound, but for the rest you need apply the appropriate thermal compound in the proper way. If you attached a fan without cleaning the surface then you need to remove all compound and begin with a fresh application. HOW you apply it is VERY important to heat transfer and varies depending upon the CPU you have, start on this page and choose your CPU type:

(CPU's cannot make noise, fix this first and look for a noisy fan and replace that too)

You have to be a little bit crazy to keep you from going insane.
