My PC is relatively new running XP SP2. It freezes a lot and gives a lot of blue screens, this generally happens when I get involved with media/films/itunes, well it is more prone then, I can usually browse quite happily and check email but when I use media it freezes/bsod. I ran memchecker and found errors, so I replaced it with new memory which I ran memchecker all night with and now shows no errors but my freezing/blue screen problems continues. I would be very grateful if someone could have a look at the minidumps and point me in the right direction? The messages on the blue screen often change, sometimes usbohci.sys, serial.sys & others. minidumps are attached, I have got like loads of these!! I have went to copntrol panel>display>settings>advanced>troubleshooter and put the slider at zero and disabled "enable write combining" it didn't stop the computer freezing. I have : AMD Athlon64 x2 4800+ dual core ATI socket 939 motherboard 2048 corsair memory ati radeon x1600pro 512mb pci express 600gb seagate SATA HD Running triple monitors.
