Hey guys. I'm not sure completely sure if this is a hardware issue, but I figure I'll post up here anyway and get your ideas. System is: Gigabyte GA-965P-S3 mobo, Intel Core 2 Duo E6300 CPU (@ 2.45GHz), Seagate Barracuda 7200.10 250GB S-ATAII HDD, ATI Radeon x850XT 256MB PCI-E, Asus DVD/RW RAM drive, 2 x 1024MB DDR2 800Mhz PC2 6400 Transcend Jetram Memory, 550W Task PSU. I've having problems with this current system. After a while with any OS the system becomes sluggish and slows down. Recently I've been playing a lot of WoW on it. I have verticle sync on so my frames per second shouldn't really ever drop below 60 by much. And usually this is the case, but recently after a few days the system starts to lag a bit... and the frames jump around a bit. Upon first boot they'll just at about 60 for a few seconds then dip to about 30, and from there over a few minutes it just slows up a lot and then my frames never really get over 10 if i leave it long enough. After each time I format the computer seems to go back to full speed again and everything is fine, I can play with my frames staying at about 60 and then thats all good, but the next day I might fire it up and Its running very poorly again. Also after leaving the game the system is slow to respond and a shadow of its former self. I really don't understand why it would do this. In as much as straight after a format the computer runs perfectly it doesn't seem like a hadware issue and more of a software issue, but if it does the exact same thing after every fresh OS I install surely something must not be right? I've tried setting all BIOS settings back to failsafe settings and I've checked all voltages etc and it is all fine. Any ideas?
