That video link crashes both IE SP2 and Netscape 18.104.22.168 in my 98SE.
"It will stay up in Safe Mode"
"I can see the cd-rom in "My Computer"(not in safe mode) but cannot get it to work."
I know from experience that you can get really odd symptoms in 98SE if the cd drive is malfunctioning, or if there's something wrong with it's data cable connection.
I'm assuming the CD drive is an IDE drive.
On an older computer it could also be a proprietary drive that does not use an IDE data connection - e.g. Panasonic (Matsushita-Kotobuki), Mitsumi, Sony, etc.
The CD drive should work fine in My Computer, but of course a disk it can read must be in it.
Safe mode in 98SE does not load CD drive (optical drive) drivers, so you see no CD drives in My Computer, although they're there in Device Manager if they're detected properly.
Disconnect both the data cable and power to the CD drive and see what happens when you boot normally.
If the computer no longer reboots in a loop,
- It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittant, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.
Try another data cable if in doubt.
- try a different CD drive.
If that doesn't help, if it has more than one hard drive, disconnect it too, try the computer again. You may need to change the jumper setting on the drive that's still connected, if it's set to slave, or if it's set to cable select, you may need to connect the end connector on the 3 connector data cable to it (older mboards /bioses may not detect a drive AT ALL if it's on a data cable by itself and it's jumpered to, or seen as, slave). You may need to change boot order settings in the bios, if you do either of those.
If that doesn't help, make sure all cards in slots are all the way down in their slots, try the computer again.
If that doesn't help....
There's not many software related things that will cause a reboot loop in 98SE.
If I've ever had that happen to me, it's been so long ago I don't recall when. I've been using 98SE nearly every day since the beginning of 2000, and I still use it.
Ask her what was the last thing she did before this first started to happen.
- did she install some software?
- did she use an anti-malware program to scan the computer and she had it remove what it found ?
- did she delete something rather than un-install it?
Check the current voltages in the bios Setup. If +3.3v if that applies, +5v or +12v are not with 10% of nominal, the power supply needs to be replaced. The CD drive cannot work properly if what is supposed to be +5v or +12v is too low, and if either is too high, it doesn't take long until the optical drive's board is damaged; if what is supposed to be +5v is too high, the floppy drive tends to fail before the optical drive.
The Win 98SE (and 98, and ME) Startup Disk floppy already has the ability to support IDE optical drives (and some other proprietary optical drives), via a generic CD driver (oakcdrom.sys) (or other drivers) and the proper lines in Autoexec.bat and Config.sys (there are no Panasonic [Matsushita] cd drive drivers on it). If the IDE CD drive does not work with that, either there's something wrong with it's data cable connection, or the drive is toast.
The original OEM and full retail version 98SE CDs usually came with a Startup Disk floppy, the same as made in Setup or in the operating system, with the additional selection of being able select running Setup in the first menu.
You can make a Startup disk while running 98, 98SE or ME Setup from the CD. You can make them in a working Windows installation in Control Panel - Add/Remove Programs - Startup Disk tab, along with the Windows CD.
If you don't have a 98SE Startup Disk floppy, you can download the contents of one from the web.
The drive is defective if the power supply is ok and the computer is running and ...
- it won't open when you press the button on the front of it when the computer is running. That only requires the power connector to be connected to it.
- if the led doesn't come on when a disk is in the tray and the tray is inserted. That only requires the power connector to be connected to it.
- if the led does comes when a disk is in the tray and the tray is inserted but it comes on again for a long while or blinks on and off a long while (that probably indicates the motor bearings are worn so bad that the the drive can no longer spin at 1X speed). That only requires the power connector to be connected to it.
- if you place a disk in the tray, note it's position, insert it, let it try to spin, eject it, and find it hasn't moved - the motor's bearings have seized - the motor's not spinning. That only requires the power connector to be connected to it.
