My computer's cpu usage is spiking constantly creating lag on the desktop. Even if nothing is opened the lag spike occurs about every 5 seconds. I've tested the memory and all tests said that the memory was fine. I hooked up my computer to three different video cards and the lag was still present. Defragmenting the hard drive did nothing. Nothing under device manager was listed as having a problem. The only thing that kind of worked was destructive recovery and that only worked until i reset the computer in which the problem arose again. Does anyone have a clue as to what could be causing this and what, if anything, I would need to replace?
3500+ AMD Athlon 64 processor
200gb Samsung SP2004C Hard Drive
Nvidia GeForce 7300 GT PCI-E
It could be a number of things causing your CPU lag spiking. Here are a couple of things that might be cusing it.
1) AMD Quiet and Cool is enable in Bios. Which you would have to Disable.
2) Ram. Since you only show 1gb of ram, I would suggest you increase it to 2gb of ram. The reason is your ram is getting used up and it is hitting your CPU to make up the difference that your system needs.
3) PSU is not supplying enough wattage evenly or is dying. Which means you should get a tier 1 or 2 PSU. Would recommend either Corsair or PC Power & Cooling PSU, from 520w to 750w depending on what Graphic card you also have hooked up.
4) House electric current is not supply electricity evenly (flucuating). Remedy for this would be to get a UPS like one of the two below.
Wow...I feel like an imbecile. After checking the BIOS I found that my computer had an onboard LAN and when it first started lagging I had just installed a PCI network card but didn't disable the onboard one in the BIOS. There's no more lag, even after restarting a few times just to be sure, so I believe I found the problem. Thanks for your help everyone.
