My computer is having boot problems.

I just installed a new heatsink/fan.
When I powered up my computer, the monitor was blank.
The computer was powered up, and all the hardware appeared to be moving ok. All of the fans were moving well and everything.
Nothing appeared on the monitor.
It never beeped which it always does as it starts up.
Windows never came on. I could tell if it did without the monitor because it makes a sound.

I checked to see what would happen if I put the old heatsink/fan back in.
Same result.

I cleared the RTC. I did this by powering off the computer and removing the plug and taking off the battery. Then I moved the jumper to the other pins for a few seconds. Then I put everything back. Then I powered up the computer.
I did this twice bcecause the first time i did it, I forgot to put the jumper back on the original pin before powering up.

Either way, I'm still getting the same result.
My computer is not booting right.

Can anybody think of anything?

bios or cmos. probably new kind of virus, try to replace new ones. how are we going to call it? it's probably a roaming virus in the hardware of your computer.
don't forget to save the old ones for research.

The jumper i did was the clear CMOS.
What do I do?

it is called a ''cold start'', but you already did that, i guess.

i described ''it'' earlier, soo find the thread please.

So when I take off the jumper,and start the machine, I have to unplug all the external devices, and plug in a new keyboard?

 

if you're the same person, yes.

 

OK. Same person as what?

 

ok I tried it, but I'm getting the same results.

 

probably wrong jumpersettings or you didn't put them back. it is hard to resolve it this way & reverse engineer the problem.

I put them back exactly as they were before there was a problem.
I tried it again, and still getting the blank screen.

Could this have been caused because I put in a new heatsink/fan?

 

maybe the fan generates a magnetic field and killed your processor.

use a compass on it to find it out and post the result.

There was a little cpu thermal-grease on the motherboard but i cleaned it off. Do you think that could mess it up?

 

your processor is burned by ''new technology''.

loki

 

What do you mean? Actually, a small amount of the grease fell around the edges of the processor.
Could that cause probs?

 

yes, i don't know how to clean it but if you succeed you are able to install a new processor and your system will work again, only when both cmos and bios are ram-memory.

 

Hate to say it, Coolskill. But I have a bad feeling about your system.

In my mind, there is two possibilities.
Your processor is fried.
Or your board is fried.

Why?
It's possible that when you scraped off that thermal grease and didn't put any more on it that caused your processort to overheat on its initial startup. However, if this were the case, then it'd most likely start up to CMOS before weirding out. (I had a laptop where I made a bad mistake, firing it up without the heat spreader on. It made it to the CMOS screen and then everything got garbled.)

Or.
When you were dinking around on your board, you might have pushed it down to where some of the pins on the back of the board touched the case. This happened to me recently while cleaning my motherboard. It fried my board and I had to buy a new one.

I'd suggest taking your computer down to a computer store. They'll usually test it for free. The only other suggestion I could make is if you know someone else with a motherboard that would accomodate your processor. Try it on his board and see what happens. Of course, if you fuck up, then you'll owe your buddy a board, eh?

Good luck. I know how much it sucks to fry your system.
Luckily, you can get new parts relatively cheaply.

Of course. I suppose the question is what type of system do you have? Is it proprietary? (i.e. Dell, Compaq, etc...?) If so, there's nothing you can do about the board.

 

don't hand them over to a computershop, you're a member of sciforums.

 

It's not a brand name.
I put the computer together myself a year and a half ago.
It has been running very smoothe.

It had been shutting down do to overheating recently. I air sprayed the dust off of all of the fans and internal parts. I tested my cpu fan speed, and found out that the fan was running very slow. I took out the heatsink/fan, and put in a new one.
This is where it all started.

Can the motherboard be fried if it still lights up? There is a LED bulb on the board itself. Furthermore, the CPU fan which is powered by the board is running, and the hard drive maked the popping noise upon booting.

But there is no beep sound, and the monitors are on, but getting no signal.

 

your creation is been killed by a ''virus''.

maybe we can build a new one together.

what did you do? i scanned the thread what's up?
