Computer Problems

Have I had computer problems lately! First my office chair developed a crack and now leans back at a precarious angle. Second the Power supplies fan started making an awful sound. I replaced it but some how blew up my PCI bus and then had no drives showing. Back to the part store for a new Mother Board. It's back up, sorta. I only show one CD drive and one hard drive...... I can't use my old video board so I'm stuck with the onboard one. I'm scared to put the sound board in ... who knows what I'll screww up next. I am just hoping I can get anoth year outta this old PC. Everybody pray for me and it.
