Ok, My friend came over with his pc and asked me to do some work on it.Which was fine I build computers and such for people as a little buisness.So he then asked after I GOT his computer booted for me to put some rom files onto his computer.So of course I agreed.Instead of wasting time installing my isp on his computer I installed his hd into my computer as a slave.So I gave him a ton of files.And when I booted my pc up after he left I NOTICED that I couldn't change certain things on my computer.Like for instance.I was setting up a new ipx connection so I could play a game between me and my g/f.And when I set it up it froze as I finished.So I thought hmmm...Maybe some sort of malware etc. was transferred.So I figured I'd check my msconfig for SOMETHING.Couldn't change anything.So I decided to enter my services.msc...Nothing would close...So I went into my computer...Nothing detected...Thought maybe my hd POWERED off or something stupid...No Dice.It's connected fine and all that good stuff...So I ran multiple scanning progs.Adaware,Spybot,HIjackthis....Did minor work and nothing prevailed.Tried to reboot into safe mode to ruin spybot and such,Except when I log on it gets an error that isn't shown and reboots.Took off all user accounts and did same to no prevail...So I'm curious on to what sort of malware,virus such could cause this...Anything else juist doesn't make sense to me. Your INPUT and knowledge would be greatly appreciated

ThanksWhat are "a ton of ROM files"?
