Hi everyone, I am having a problem with my GF's computer. She used to have an IBM Thinkpad but it has recently broke down and her brother bought her an old Acer Travelmate 290 for use in the meantime. Anyway, the computer was badly infected with a virus so she asked me to fix it. I basically formatted the C: drive, set up windows XP SP3 and reinstalled all the software, including Kaspersky Internet Security 2011 for the virus scan. However, the wifi stopped functioning right after the format. Prior to the format, it ran nicely. However, now the computer would go into a blue screen every time I turned the wireless router on. If the router is off or the wifi button is not turned on, the computer works just fine. The blue screen would say Irql-not-less-or-equal stop message *** stop:0x0000000A (0xFF1701F0,0x00000002,0x00000000,0x804D9B64) I have tried to google the problem and the only solution seems to be updating the wireless driver. And for the last two days, I did just that, having downloaded the driver from Intel site and from Acer site. However, the problem persists. Attached are the last few minidump files from her computer. Please help! I'm at my wit's ends!!!
