Friend of mine had a PC that was constantly giving him a BSOD.
I went round but it hardly did it.
I was 50-50 but he did say that it can go for hours without a problem, then it can be a pain for ages and crash every few minutes.
I asked him to write down every time it did BSOD the numbers and the error etc and I went through it according to the info we collected, but again, the PC seemed to be just fine?
In the end, I said to him that I will take the PC home and let him borrow one of mine... I gave him my XP2400 Setup ( Aty the time, that was a good one ) as that one NEVER crashes, and the next day after his PC had been running at 100% doing all kinds of banches and folding and various other stress tests including converting loads of AVIs to DVDs all at the same time, well you know the score, and it was still solid as a rock, I phoned my mate up, who told me that the Pc I gave him was just as bad.
Clearly it cannot be the PC then.
So, a bit of detective work needs to be done here...
What has my mate done recently?
Well, he said he installed this or that, but I told him that for both PCs to do teh same thing like this, has NOTHING to do with the software, it must be somethign else.
He said he moved the PC, Again, I said that this is unlikely because both Pcs are fine at my house and bad here, but I asked where he moved it from...
It was in teh living room, its now in the bedroom.
Will he move it back? He could but he moved it here for reasons and so, I said to use an Extension cable from the living room into the bedroom, and see what happens?
Needless to say he didnt phone me at all for 3 days.
When I phoned him up he said that his PC hasnt crashed once.
So, I re-wired his flat and he has not had a problem since then. Billed to his landlord of course.
Turns out the wiring in the flat itself is just crappy.
In total, these problems had gone on for a few weeks but it took us about a good couple of days to actually resolve.
