Now to show just how much of a noob I am with computers
Running Vista home premium 64 bit. To start with when first built, the comp was running nice and smoothly. However it started to slow down a bit, and maybe 12 months after building it, I reformatted it. After reformatting, it still didnt run "as new" and became sluggish much more quickly. Id understand if it was because resources were maxed out, but generally task manager etc reports about 50% ram usage (unless photoshopping), and the CPU hardly ever maxes out, going between 25-50% on both cores when doing things. The problem is though, things liek firefox are getting a bit unstable where Id open a new tab, or go between tabs, and firefox will become unresponsive for maybe 10 secs and then load. Word sometimes doesnt load properly when opening a file, and it takes an absolute age to boot up fully (several minutes).
Specs are (Copied from order histories):
ASUS P5KC AiLifestyle Series iP35 Socket 775 8 channel audio ATX
Intel E6400 (2.13ghz)
2x 500gb Western Digital Sata II drives, both have about 90gb left (WD5000AAKS 500GB SATA II 7200RPM 16MB Cache)
EVGA 8800GTS SuperClocked 320MB DDR3 DVI PCI-E
OCZ 2GB (2x1GB) DDR2 800MHz/PC2-6400 Gold XTC Memory CL5
OCZ 2GB (2x1GB) DDR2 800MHz/PC2-6400 Platinum XTC Memory Kit CL4 2.1V
Antec EarthWatts 500W 80%+ Efficiency PSU - 80mm Fan 4x SATA 2x PCI-E
Could it be that either the ram, or the CPU, is dying/corrupt? Its the only thing I can think of that could have caused it to get sluggish pretty much straight after reformatting. Theres nothing that loads in background that takes up loads of resources etc. I might try and run memtest tonight to see what that thinks, as I have the bios running the ram at 2.1v, and theres 2 different kinds of OCZ ram in there.
Any suggestions on what to look at, or upgrade, welcome. Is it possible to run a test like memtest, but for Intel CPUs to see if they are damaged or anything?
