I am running win 98 on with a celron 333. When I turn on my comp it goes to a black screen and says operating system not found. After trying different things and turning it on and off a few times now it won't get any power to the monitor. It does nothing. I hear the hard drive work in the beginning but that is it. Any ideas?

Check the memory modules for seating or to see if they are bad

Using a windows 98 startup disk insert in floppy and boot computer,at command prompt type FDISK /MBR,reboot
Now boot computer with the floppy inserted and try the option to run setupwithout cd rom support

The last suggestion would be to run scandisk on the hard drive to check for any errors

I tried booting up with WIN 98 STARTUP DISK and it didn't do any thing. You just hear the fans running but nothing on the monitor.

Depending on your computer as it boots up it will say hit (del),(f10), (f1) for setup do that. And look at the settings find the setting for harddrive if has nothing listed or is set to none your mother board battery may be bad. You can try to set it to auto or look at the hard drive to see the settings for it. You need to think about a few things, a virus has changed your boot sector, your boot sector has gone bad (boot to a dos disk and run scandisk /autofix) your battery has gone bad, your onboard controler has gone bad (if you have two ide slots on the motherboard switch the connection and see if it helps)your cable may be bad. Ask me for more

Boot your PC with Windows 98 bootable disk. Then type "FDISK", follow by option 4 to see if the hard disk partition exist. If yes, exit from "FDISK", then type "SYS C:", and your PC will be fine. If not, then I guess you got to re-partition if the hard disk is still partition-able. If your hard disk cannot be partition, then you have to get a replacement.

Hi

First of all. check your BIOS configuration and make sure that your computer boots from A before C.

Next boot from a startup disk, and assuming you can see an A\:> prompt, type:

SYS C:

and press .

If you cannot see a prompt when booting from the floppy, you should check your hardware, make sure all cables are firmly attached and are the right way round, make sure all memory is properly seated etc.

Good luck

With no video, I would try the following.
1. After verifying the video cables are all securly connected, open the PC.
2. Remove the video card and turn on, listen for eight beeps. If yes, replace video card. If no, go 3.
3. Pull RAM, and trun on. Listen for three beeps. If yes, replace RAM.
If no, unplug all drives from power supply and try again. If you get 3 beeps now, put the RAM and video card back in. Try again. If comes up, restart computer with one drive plugged in at a time. One of them is fragging the power supply.
If doesn;t come up with no drives plugged in, either motherboard or power supply problem. PS easier to try, so I would start with that.
Be careful about trying PS on another computer. It could frag part of it.

As far as the video is concered, I'm not too sure. But, if you get that working and you still have the message come up saying "no operating system found", sometimes it is because the mouse is loose. Make sure all your connections are tightly in on the back. Sounds weird, but you would be suprised...
