HI All Sorta DIY - I'm trying to fix it myself
WinXP Pro SP3 PC, Dell fairly basic desktop (Vostro 200), about 4 years old, fully updated, running Avast antivirus & Spybot. Every so often, the PC just locks up solid, not responsive to mouse, Alt-Ctl-Del or anything else... Only way out is to pull the mains plug (I know it's not a good idea - but what can you do ?)
Happens most often when running a particular web authoring package (Netobjects Fusion) - but has also happened (once) with another web authoring package (WYSIWYG).
Tried blowing the muck out of the PC fans etc. - but doesn't seem to have made any difference. Lifted & reseated the memory.
I'm a bit at a loss for where to look next? Any ideas, please ?
Thanks Adrian
