My sister has a PC preloaded with Win98SE and has IE6 &OE6. When she powered it ON today there was a continuous whining noise from the processor and it was not booting. The fan is working. What could be the problem and what is the remedy?

When you say the fan, do you mean the CPU cooler fan, or the fan that's inside the power supply?
The CPU itself can't make a whining noise. The CPU fan (or any fan) can - and with age frequently will.
If both the CPU and power supply fans are spinning (and spinning at what appears to be the correct speed) but the system is not starting, you should be seeing the usual boot messages on the screen.
Most likely, the noise you are hearing is from the hard drive, indicating that the drive has died.
A few weeks ago I had to deal with an NT-4 server that all-of-a-sudden failed to operate / boot properly (It runs 24/7) and it's hard drive was making horrible screaming noises.
This was a Western Digital 40 gb drive, made Nov. 2002.
I fixed the problem by swapping the drive's circuit board with another spare drive of the exact same make and model (and approx. manufacturing date). No data on the drive was lost.
Any systems that are original win-98 systems are at high risk for experiencing hard-drive failure, unless they experience extended periods of non-use (months to years).
Another way to put this is that all hard drives 40 gb and smaller are, today, at the practical end of their useful life - assuming they are on at least a few days a week since they were bought.

I should clarify that you should suspect the power supply first, but if all fans are spinning properly then the noise is probably coming from the hard drive if the system is not booting.
If the noise is coming from the fans, noisy fans will not prevent the system from booting.
Another thing to check is the battery on the motherboard. Most likely it is dead, and the CMOS/BIOS settings have reverted to default values, and the system time and date have reset as well.
Replace the motherboard battery (most likely it's type CR2032 - looks like a big coin like a quarter). You should be seeing a message at startup wanting you to enter the Bios setup menu and enter new settings.
If you see NO video activity at all - none of the usual startup text during boot-up, then it's probably the power supply. If you DO see startup text on the screen, then change the battery and fix the bios settings IF you are being asked to do so. If none of those two are occurring, then the hard drive is likely the problem.
I meant the power supply fan as I am yet to open the PC to check if the CPU fan is working or not. If it is indeed the hard disk, then it may be difficult to get the same make and model in the market today (20GB). It is probably a Pentium 3! I have to check this. As to your other query, there is NO video activity at all.. There is NO start up text. However, for what it is worth, I can put a new motherboard battery and see if it works. In case it still does not work, I would like to know if a Pentium 3 will take a 60GB or 80GB hard disk?

A 60 or 80Gb disk drive should be no problem. It's not whether it's a P3 or not, but the capabilities of the BIOS, and that's not likely to be an issue. Above about 128Gb you will have to make special provisions, and it becomes much trickier. A faulty CMOS battery will mean that the clock won't keep proper time and you may need to reinitialise BIOS setup on each startup, but it's not critical. -- Jeff Richards ----------------------------------------

So you are saying that the noise you are hearing is coming from the power-suppy fan (or from inside the power supply) ?
> there is NO video activity at all.. There is NO start up text.
The problem is almost certainly the power supply.
The only way you can tell where the noise is coming from is by taking the cover off the computer. You should do that, and disconnect the cables going to the hard drive (power cable and data cable). Try turning the machine on one more time after doing that. The hard drive might have died in such a way as to put a load on your power supply and prevent the motherboard from booting up. Disconnecting the hard drive would remove the load and allow the motherboard to boot. If you still hear a noise and you get no video after turning it on, then the power supply is the problem.
Replacement power supplies can be VERY inexpensive - usually $30. But that's if the computer is NOT a name-brand like dell, HP, compaq, etc. Reason being that name-brand PC's tend to size their internal components in non-standard or custom ways. Unlike other components (floppy, CD, hard drives), power supplies come in many different form factors. The $30 power supply you could buy from the local discount computer parts store will likely not physically fit inside a name-brand PC.
Don't mess around with different hard drives or motherboard battery at this point. The problem is the power supply if you're not seeing any text on the screen. Don't try turning on the machine again. The power supply is not putting out the correct voltages and you might dammage the motherboard - it might be dammaged already.
Your best course of action at that point is to remove the power supply and take it to your local computer parts store(s) and show it to them and ask if they have a replacement of similar physical size.
An excellent response with good advice (I have a Compaq/HP office machine and it has THE most ridiculous 175W non- rectangular with non-standard connections power supply) but plagued by a misspelling of "damaged"... ;-(

Unplug the computer, open the case and remove and reseat the memory modules. If this doesn't help, you might try removing and reseating the processor.

Memory modules that are either not installed or have contact problems would result in the motherboard issuing a few beeps during the POST sequence. The OP does not mention the motherboard speaker giving any beep codes.

Not recommended until the power supply is at least tested with a volt meter. It can be a pain in the ass to remove the CPU and deal with the heat-sink thermal compound. If this is a Slot-style P2 or P3 processor, the entire CPU cartridge can be flexed slightly back and forth, and that should be enough to resolve any poor contact problems. If the processor is a socket type, then it's quite rare for those to exhibit contact problems.
The OP is advised to get a simple DC volt meter and check the yellow power-supply wires for +12 volts, and the red wires for + 5 volts (each with reference to the the black wires. Only one yellow and one red wire needs to be checked - not all of them.

Agreed. No video even at startup, in my experience, is either power supply, or memory or video card has worked (marginally) loose.

Agreed - have power connections to only the motherboard; in practice you need only a processor, some RAM, and the video card (or on-motherboard video if it is of that sort).
>Replacement power supplies can be VERY inexpensive - usually $30. But
Agreed; I'm not sure what the exchange rate is, but I've seen them for 14 pounds or less. But, ask around - someone may have one they could lend you.

Another reason for borrowing one - _provided_ it has the right connector for the motherboard, you can try it just lying alongside, even if it doesn't fit, to prove the point.
>Don't mess around with different hard drives or motherboard battery at
Seconded. Until you've got start-up video, those aren't needed (though disconnecting the HD etc. isn't a bad idea).

Can happen, I suppose; I've never had one myself. [] -- J. P. Gilliver. UMRA: 1960/<1985 MB++G.5AL-IS-P--Ch++(p)Ar@T0H+Sh0!:`)DNAf ** http://www.soft255.demon.co.uk/G6JPG-PC/JPGminPC.htm for ludicrously outdated thoughts on PCs. **

Although he doesn't say it didn't either, I _think_ I have had ones appear completely dead in the absence of memory.

Agreed. _If_ it's the sort of CPU that's in a square socket, you could _carefully_ rock it slightly - but don't break the seal between it and its heatsink and fan, probably not worth the risk. (The paste joining the two can become brittle.)

Indeed.

Indeed.

Indeed. There is another possibility: assuming it's an ATX power supply (the sort that turns itself off when you shut it down, rather than you having to switch off at the switch, which will be a definitely two-position switch in that case - old type, but did survive into the Windows 98 era), then the control lines that tell the supply to come out of standby may be at fault somewhere. The fact that it comes on to the extent of making noise, which probably means the 12V lines are coming up at least, means it probably isn't that though. -- J. P. Gilliver.
