My computer is very old so, i can install only win98

Frankly there is no security on Win98. To get into the machine just type in a new username and password.

use virtualbox or vmware player and use a win98 or XP image..

windows 98 in year 2017, why/?
good luck,
why mess with this old box.
why not get a 10 year newer box for near nothing at GOODWILL.
really this box is land fill fodder. now. know body beats there head on w98 now....
mx.com no support
hp.com no support its on the no support page, seen here
Compaq Presario Media Center SR2030NX Desktop PC
so if a driver is bad (hell the hardware is too)
then go to the chips that fails home page

the mobo is ASUS>
A8M2N-LA
may be the they have 19 year old IDE drivers for win98

GeForce 6150 LE chipset
the IDE is nforce , (old)
the only hope is Asus, old pages or nvida relic pages.

Sounds like the hard drive has failed.

Do you want to replaced the main HD or add a new one? If you want to replace the main one, buy a Hard drive under 160 gigs. I cant remember but 98 can not deal with a bigger one, you will have to cut it up or Partition it. Partition it down to 20 gig each. Do you have your Org. win 98 install disk? Get a setup program with the HD you buy. That program should let you Partition it and also format it to use with 98 or fat32. Once installed in the computer set the HD to master with switches located on the drive (small jumpers) As it boots up look for press DEL to enter setup. Get into the BIOS program and ck to see it it will locate your new hard drive you might have to set heads and scetors so make a note of the stamped on the drive. Once the BIOS has found the drive it is a matter of format w/ copy the command comm program from win98 you will have to have a good win 98 set up disk. Once you have formated the drive with fat32 and copied commamd.com you will need to install CD/Rom drivers you might have to find a good old win98 starup disk to boot up the cd. you might find a good old floppy with a cd intall on it at a local computer shop. if using an old win98 startup disk you can then put in the cd and at the Prompt type in cd win98 then type in  setup and that should be a good start. 

Change your bios setting to boot from cd. restart, choose start with cdrom support and follow the instruction

u install old version dvd driver in your system (Windows 98 compatable) and enjoy

this is compatability problem. You should install your printer on Windows XP system. Then make it share for all. I think it will print from both 98 and XP. try this.......good luck.

Try going to the Asus website and look for support for your MB drivers and Operating System.

If there is no longer any Win98 support for your MB then I suggest a fresh computer and more recent software for less hassle!
A ten year old OS indicates to me that you might be stuck until you go with the flow!
Cruel but true.
Hopefully the recent cheap prices for computers pre-installed with Vista or XP will persuade you.
