Win 98 was never real good with memory. If i did not reboot the computer every day i would get errors in programs when trying to run them. If i tried running 2 days without rebooting the puter would lock up on me. So i just rebooted everyday and the puter ran fine. The more programs you have on the computer the faster it will start having problems. I remember wiping the drive and reinstalling windows and a few good programs i liked. The computer still needed rebooting every day but other than doing that i had no problems with it. Before the reformat i had over 40 programs on the puter.
One thing i don't like about the H-P is that they put low powered power supplys in most of them. When you start adding cd burners, dvd burners, graphics cards, sound cards, and other hardware the poor old PS just doesnt have the power to keep up. You can get a bigger PS but normal ones don't fit and the wiring sometimes is not standard like aftermarket PS's. As you add more hardware to the computer it starts crashing more often. Of course i find this true on most of the factory built computers. Thats why i started building my own computers years ago. These days if you like modifying computers to be better you must start out with a custom computer you build yourself( or have someone build it). I find most factory computers somewhat lacking in the hardware department.
