I recently started getting a blue screen at startup. It tells me to check newly installed software or hardware, & to dissable memory cache & shadowing in the bios. I've not installed any new software or hardware in the last couple weeks, I only use this pc for surfing the net & email. I also checked the bios & these above items were already dissabled. But still I keep getting this blue screen every time I try to start the pc. Any help would be muchly appreciated. thanks, Maxx

even when I try to boot in safe mode, I get a "Stop fatal system error, Longon process terminated, system has shut down"

Just a stab in the dark here. Try reseating all your RAM 3 or 4 times to scuff up the contacts.

I'd start by booting up the xp disk going to the recovery console & running chkdsk. http://support.microsoft.com/kb/314058 You might want to try to copy any files you want. Before posting try google. Backup. Use anti virus software.

Thanks for the input people, When I get time later today, I'll try your suggestions & post my results. Thanks to all Maxx.
