Hi, Apologies for the language, but I normally speak dutch. when I install sp1 (vista) through update, on my laptop IMSI ER710 , the cursor flashes abnormal. And Temperature of processor rises to 71° c, normally 43° c. when I remove sp1, then cursor is back to normal. And Temperature of processor drops to 43° c. I have renewed all drivers, no result. Has someone a solution, thanks. cyberfixer
