In the last few days i've been getting a windows startup message (where there's that window's blue screen) that says "isdelete program not found-skipping autocheck". It dosen't appear to interfere with anything except stalls boot-up or 5 seconds or so. I'm pretty sure my windows xp home is up to date (or maybe 1 week off) and the last program i've installed in rivatuner 2.06. I'm thinking the problem might have to do with diskeeper trying to run something at startup, because i don't think it's a window problems because i don't see any real records fo this problem happing there or at dejanews. I have a pentium dual core 1.6ghz oc'ed to 1.92, ocz 667 ram oc'ed to 800 mhz, a 8600gt card oc'ed to 675/1450/875, and an asus p5nsli mobo. Thank you for any help you can provide!
