Hi I'm trying to help a friend with a BSOD problem. I've looked at the minidump-file, but I'm not really sure what to look for... There's no STOP in the file but there is the following warning: WARNING: Stack unwind information not available. Following frames may be wrong. 81cf8740 00000000 81cf8748 81cf8748 81cf8750 nt+0x91048 Is there some information missing? Before this started I helped him replace his noisy PSU and CPU fan and I really hope that I didn't cause the problem, but the timing isn't so encouraging. I'm thinking about switching back the PSU, but I thought I should ask here as a last resort.
