It should be the issue of your harddisk or RAM incompatible with your motherboard.
To resolve(try one of the following):
1. Update your motherboard BIOS to latest version, remember to update them one by one, say, 1.0 to 1.1, 1.1 to 1.2...etc. It should help to resolve the compatible issue between RAM, VGA, harddisk, CPU to motherboard
2. As your config. is old, pls check your harddisk is running under the "old mode", for example, some new harddisk support 3GB/s mode, as your motherboard is old, you should limit it to 1.5GB/s mode. check your motherboard manual and see the best mode of your harddisk
3. RAM address issue, did you update your XP virtual memory setting? after you replace 256M ram with 1GB ram, you should also update your page memory in control panel to higher, for example 2GB or 4GB, so that the memory demanding application can run properly.
4. Partition size, under some old config. the CPU may be in-capable to handle large partition size(it can, but slow and easy to hand), are you using "one" partition in your new harddisk, if yes, you can try to cut it into 2 or 3 partition, since your O/S need to read the complete TOC of a drive everytime when it read, for example, cut a 250GB harddisk to 120GB and 130GB instead of 250GB.
It is unlikely that the problem came from power supply, since RAM and harddisk do not require a lot of power to run, it is unlikely that the problem came from power supply(unless you replace VGA card or connect other new device), you can test this, to unplug the power of your CD/DVD-ROM and floppy, and see if it work correctly.
Hope this help!!! ^^
