newbie needs help

[mrjiggy]

Hi peeps. Here is my problem, and I would appreciate ANY help I can get. I have a PIII 500 with a 20G seagate HD. I was burning a cd the other night and my PC froze. I got PO and smacked my PC kinda hard and blew the power supply. I replaced the PS and now when I first boot up my PC takes about 50% longer to get to my desktop and for my icons to load. I burn CD's through roxio for Back-up's and Roxio tells me the CD's are complete, but hangs during the final verification process. When I go to check the CD after burning, windows tells me that the CD is blank, and it doesn't seem as though it is even trying to access the CD drive. When I initially go online, my home page takes about 50% longer to load as well. after that the web pages load easily. I ran virus scans, defragmented, scan disked all drives, ran hijack this, and all seemed fine. My hard drive does seem to be making a little more noise than usual, and defrag took a LOT longer than usual. Any suggestions? TIA
