Recently in the last 2-3 months I have been having issues with my computer.
Here's the hard ware
*AMD Athlon 5400+ 2.8 dual core
Gigbyte Ud3 something mobo
EVGA gtx 260 superclocked
730 watt Raidmax PSU
*2 gigs OCR dual channel memory
4 gigs ADATA dual channel memory both at DDR2
*160gb Sata hardrive
320 bg SATA hardrive that I pulled out of an external that was having usb errors
the starred components are original when I built the computer 4 years ago.
First it just started slowing down at boot and the mouse would start lagging around the screen even just opening programs.
It also started just having general issues that I contributed to a bloated OS win 7. I did a fresh install and was plagued by constant BSOD's. I did another fresh install, and now have had only a few BSOD that say USB_xxxxx_xxx (can't remember exactly). However it did have constant memory errors, so I took a stick out and it was cured. But then I checked the stick with memtest86 and it was fine. So I put all the memory back in a different order and it works fine now. I have also noticed that the CPU temperature is riding much higher it used to. Normally it was around 41C and it would get up to maybe 55C when playing games. Now it is around 46-50C and is hitting 60C during games.
Just recently it had a problem where it froze except the mouse would move for about a minute than it recovered and was fine. It takes a longer time to boot to windows. Keep in mind but are a couple more startup apps (speedfan and EVGA precision).
I am curious, does this seem like it could be the CPU or HDD or something else completely. Those are my main concern because they are the oldest.
the 320 gb hardrive has been in the computer for nearly 9 months and it had no issues after I took it out of its external USB enclosure. So I don't think it is that.
Unstable power could be a factor.
A Raidmax psu doesn't exactly scream quality and reliability.
I'm not saying it's the problem for sure but i would be checking it out very closely.
A poor psu will degrade and damage other components over time.
A multi-meter....... would be able to check the PSU, if you know how to use one, plus any of your friends might have one.
Or one of those inexpensive gizmos that connect to each power outlet on the PSU and shine those leds to tell you if the power is right or not.
