Thanks!
I'll keep an eye on the memory (well, I'll remember to do what you said0 if it breaks.
Right now (after a repair/reinstall) of Win Xp it is working.
How long it works though...
Only thing "weird" that has happened was, freshly installed WinXP media center version.
This gave me IE 6, during the auto update process it aksed if I wanted to install IE7, said yes.
It installed *really* quickly (like maybe 10 seconds, more like 5) and wanted a reboot.
Rebooted and IE doesn't work.
I have internet connection, I can play games online,I can update virus guard stuff online, I can't surf or get to any site you need to have a browser for. (Including Windows updates that you can select yourself)
Dh suggested I delete IE7 and it shoulkd rollback to 6, didn't work.
Now at friends DL Firefox (I've heard good things about it, maybe it's time I tried it)
So hoping this will owrk.
Thanks all for the ideas/suggestions, hopefully won't be back.
