Thought BSODs had been done in, but NO!

For a while all seemed Ok after I closed thread Mouse pointer freezes
and subsequently updated the BIOS and a number of drivers, using either Dell's or manufactuerea' download sites.
I also, of course, made sure I had Firewall and Antivirus installed.

Trouble seems to have arisen, however, in the last couple of days, as can be seen from the SF zip attached ( and FWIW the Who Crashed me log).

It's driving me mad, so I hope that once more you will help me.

Thank you in anticipation. :)

Although I had uninstalled ASC, using Jaycee'stoll revealed a couple of stray files.

Furmark, the temp levelled at 68 deg.

WD Data Lifeguard showed nothing on extended test

MemTest, I ran for 5 passes and nothing emerged. Is that enough to deal with 4 sticks @1GB?

Should I bother about USB hub and ports, and is there a way to prove them without a device installed to each?

Unfortunately our house's consumer unit RCD has been tripping out recently. We suspect it might be the freezer.
Might that bring about or exacerbate t the type of problem I am seeing?

All the guff that falls under Universal Serial Bus Controllers in Device Manager; nothing unpluggable.

I'll try that, but am not sure how that might help my problem. can you please help me understand? :)

My confusion about the possible aid from the tutorial remains. Help please.

Thanks for coming back.

Possibly Probably a very silly question, but how to choose ports to suspend?

A rocking horse asks is a USB root hub the same as a port?

Once the culprit had been IDd how would a repair be done?
