Hello Akujiki! Welcome to PCHF
My first question is, when does the unit start to get slow? Does everything go normally until it hits the Windows splash screen, then it just takes a ton of time for the desktop to load up? Or does it take a long time to even get to the Windows splash screen?
If the entire bootup process is slow, then I would start by doing two things. I would first reseat the memory, which means to take it out and put it back in. Then I would download this tool -
Memtest86 - Free Software Downloads and Software Reviews - Download.com - which is a great memory tester. You burn it to a CD then boot off of the CD. Let it go through 2 passes and see if any errors show up. If you see errors, then your memory is bad.
If your whole boot process is ok, but Windows itself is what is taking so much time, then besides bad sectors, you are likely to not have any hardware related issues. And btw, 256 megs of memory may be low, but in a healthy computer running Windows XP, it is enough if you are doing basic computer stuff.
If everything checks out ok with your memory, then my best guess would be that you have some operating system corruptions. It could be due to malicious software which you say you don't have. You could also have bad sectors which are corrupting some of your operating system files. You could try running chkdsk /r to help that.
That will be a good place for you to start. We can go from there.
Again, welcome to our forum. Hope that helps
