I have a AMD 1700xp running in a MSI KT333 ultra 2 mobo, with 512mb ddr, an ati 128mb video card, a audigy platinum 2 sound card, a dvd drive, a cdrw drive, a maxtor 80gig ata133 drive, and a fujitsu 27gig 66mhz drive. The powersupply is an enermax 350w (might be 400w, it is pretty new). The system is running Windows XP professional and is fully patched, with Norton Antivirus 2002 running on it, behind a firewall on my network. My problem is that everything runs fine for a while, maybe its over 2 months since my last reinstall, but now its hopeless to use. Late one night, I got the BSOD and when i rebooted, it couldnt find my hard disk. This continued until i turned the power off on the front of the case, after this the hard disk was found and windows rebooted. Now tho, the pc is slow. its as if something else is taking up the cpu cycles. ive looked in taskmanager and nothing is there apart from svchosts and the usual suspects. I went into lots of tweak sites and turned off lots of services, and have improved the boot time from over 1.5 mins to less than a minute, but when i do stuff (like using my browser or opening "my computer", the pc freezes and disks alot, before getting where it was going. during games, the screen may freeze as the pc disks to find stuff too. im pulling my hair out. ive done virus checks, tried repairing xp (didnt work), ive reinstalled but i dont want to do it every 2 months. ive run powermax from the maxtor website, and done the full scan. it says my harddisk is fine. i know the fujitsu drive has bad sectors, but ive removed it in the bios and in windows, and it makes no difference overall. I know the problem is probably a unique one due to my configuration, but if anyone has any ideas (or any obvious opinions), it will be of great help. otherwise i have to reinstall and fingers crossed it doesnt happen again.
