I would check all the connectors. Lightning sometimes blackens them which makes them still work but not quite as before. Also maybe your boot disk and/or computer is too full with all you did? Hope this helps - Amos
some time ago i had a lightning strike, it killed my ethernet connection, my router and my graphic card (nvidia 5200 fx, RIP). i've replaced the card, the router and the ethernet conenctor and also decided to upgrade a little, so i have doubled the memmory to a total of 1 GB and bought a new hard drive to be a secondary (both 80 GB each) to put a linux system on it. now, the computer did in fact boot and worked much faster with the added memmory, even after i've installed linux.
now, the problems started after i've had a problem transferring files from the linux file system to the FAT32 partition on the new hard drive (nothing changed with the old one). i think i forgot that one thing fat32 didn't have was long filename support so it totally screwed it up. it was so bad i had to format that partition (as NTFS) and then convert it to FAT32 through linux. ever since then the windows XP i'm running boots up slowly and programs load up slower than ever (not as slow as the booting, though). there is no malware on the computer (i have zone alarm suite with it's antivirus and antispyware, spybot, ad-aware and did an additional scan with clamwinAV).
any suggestions as to what might have caused the problem? if there's any additional information you'd like, just ask.
