A couple weeks ago, I started having intense problems with spyware. It caused my windows explorer to crash every 15 minutes or so and instantly relaunch explorer (not restart computer). When I ran AdAware/Spybot/Malwarebytes it would get rid of them and it just came back soon after. I kept putting off fixing it for good, but recently, when upon restarting the computer, it would get through loading Windows and would immediately bluescreen and force a restart. I have not installed any new hardware in a year or so, and no new significant software for at least a month. Attempted solutions: - Run in safe mode. Similar to normal mode, right before windows actually pops up, blue screens to error "STOP: 0x000000BE" - Boot off friend's XP Pro CD (remember I use XP Home - I can't find my disc anywhere). Makes it to "Launching Windows" then blue screens to error "STOP: 0x0000007E / pci.sys - Address F78E0BF base at F7487000, DateStamp 3b7d855c". Tried booting to CD multiple times. - Boot off friend's Vista CD. Sometimes it blue screens to same XP CD error, and sometimes successfully launches to Vista screen at which point I don't continue. - Booting with either of my 2 RAM sticks taken out. Comp details: Processor: Intel Core Duo CPU 3ghz HDs: 1 SATA Hard drive (holds OS), 1 IDE just holding information. SATA has at least 50gb free, IDE has at least 2.
