AGP texture acceleration greyed out

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Hi have just lately noticed that getting the occasional
stutter when playing games and when going into DX Diag
notices AGP texture acceleration is greyed out. Searched
knowledge base and found article to do with Geforce 4
cards having the same problem so checked bios AGP is
enabled. Checked some other forums for advice reinstalled
graphics drivers, board drivers Direct X, all to no avail.

Anyone come across and apart from formatting and
reinstalling from scratch can solve the problem.

System specs are MSI K7n2 Delta L 2500XP barton processor
1gig of RAM, Radeon 9800Pro graphics Windows XP Pro SP1
OS.
