bluescreens in different situations, not properly working internet

[moroga]

hi folks

i reset my sys and now all my problems started... i get several bluescreens most of them with irq faults. sometimes when i change from wow to desktop and sometimes in other cases (like play a game and usw "ipconfig" in cmd at the same time). i installed the latest bios, chipset and graka drivers.

also all hotfixes are installed and the sys worked as good as fine before reinstall... (used memtest over night without any errors)

i also noticed, that i canīt open a request from google (error: server isnīt reachable) but when i relaod the same request i come through ?!?

what might be the reason and what can i do ?

my sys:
athlon x2 64 4000+, 2048mb corsair, asus m3a32.mvp deluxe, powercolor 3850 256mb, winxp sp2 pro

Without any exact errors, it is impossible to troubleshoot your issue.
Note the stopcodes that the BSOD's give you.
Also check your XP log for issues (rightclick my computer and choose manage).
