I've run the memtest and it showed no errors with my memory..
the bluescreens are not showing any specific file or reason, it simply says "0x00000001E" or something like that. the details in the error screen on reboot say "1e" as the error code. and event viewer just says it restarted from a bugcheck, nothing more.
system specs are -
-ASRock K10N78M AM3/AM2+/AM2 NVIDIA GeForce 8100 Micro ATX AMD Motherboard
-AMD Phenom II X2 550 Black Edition Callisto 3.1GHz Socket AM3 80W Dual-Core Processor Model HDZ550WFGIBOX
-WINTEC AMPX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 3AXT6400C5-4096K
-Western Digital Caviar Green WD5000AADS 500GB SATA 3.0Gb/s 3.5" Hard Drive
-EVGA nVidia GeForce GT 240 Superclocked Video Card.
when i checked the memory dumps, (very unsure what I did exactly, followed online instructions with debugging) among all the "symbols file not located" stuff, it said the error is probably tcpip.sys
I'll attach some dump files when it happens again (I cleaned them out with CCleaner accidentally)
