Hello all, I registered here because I did a Google search and found people who can interpret Pstat output. My problem is mostly described in the title, once in so many hours I get a BSOD, I'll give you the exact error I got last time: "DRIVER_IRQL_NOT_LESS_OR_EQUAL Stop: 0x000000D1 (0x00000028, 0x00000002, 0x00000001, 0xF7B87B4A) usbohci.sys - Address F7B87B4A Base at F7B86000, Datestamp 41107d62" (I skipped the part about contacting the admin and shutting down to prevent damage.) Anyway, attached is the output that pstat gave me, any help is very welcome. (The stats of my PC should be visible, I filled them in in my profile.) I read that several BSOD's are needed before anything sensible can be said about it, this is the first one I wrote down so I'll have to wait for more... EDIT: I found out that I don't need to copy the BSOD by hand, I included the last three BSOD's now. The latest one should be the same as the one I typed above.
