My system is s-l-o-w...

By peetree ·
I recently have been having significant problems with my system. A little background information is in order. About 2 weeks ago my Power Supply began to make noises like a coffee grinder. I figured I required a new PS - it a dual fan. It began to gradualy make a normal noise, all the time I monitered the fan speed and temperature; all were within normal parameters. That wasn't the problem, however the sound came and went. Then a few days ago my mose cursor began to skip violently, the sound was garbled and choppy and some apps. (ie My Computer) were hanging up or not working at all.

Any ideas what caused (causes) it to act this way?

Are you sure it was the PS grinding and not the HDD
try running a utility to check the HDD. Beforehand, you may want to backup data

I am sure it's not my HDD, the sound was eminating from the top, rear; where the PS is. For the past day it hasn't done it as much. Perhaps a bad/corrupt driver, apps. trying to get access to a port? Hmmm... I don't get the jumpy, jitterey cursor or hungup My Computer sometimes after I reboot, not shutdown and restart. This leads me away from the fact the CPU or MB is overheated. It's like its trying to put a round peg into a square hole.

to me its look like "heet" so you should check the computer bios for cpu tempreture -- you can do it by press "del" key in the keyboard while your computer in is very first begining of initializing and then go to hardware monitor and look for cpu temp' and chasis temp' it must not pass the 50c^ and the chasis temp' shouldbe less then 35c and if they both look fine try to replace the PS with other.. and for last resort try run SIS OF SANDRA software it will simulate a heavy uty stress on your system and will show you the resault.. cheers

Have you opened the case and physically looked it over? Maybe something is getting in the way of a fan (like a wire). I would look around, check to make sure things are plugged in well and not loose, and make sure nothing is around the fans.
Aside from that, I would still check the hdd, and check for heat related issues. If you must, try keeping the cover off until it happens again, then you can pinpoint the exact thing that is causing the sound.

Find yourself a can of freexe spray and investigate the chips around the ports
(PS2 nor USB) when the mouse is acting up.
Although the whole system sounds like it's
too busy doing something else. Check the
task manager for applications running.
Just for S & G run a spyware tool, and
disconnect the cable to the NIC.

Well the noise will be one of the fans bearings failing which will be slowing down that fan and allowing the internals of the PS to overheat. You can not monitor this. But when it happens it can cause the Voltages to go off the specified levels and damage the rest of the unit.

For example if the +5 V DC goes too low you'll loose the MBR's on any HDD's fitted. If the CPU voltage goes to high it will burn out the CPU so as a starter I would replace the PS and see what happens after all it is the cheapest part of any computer and even a Good one like an Antec will save you far more in the short term than continuing to run with one that you are unsure of and run the possibility of destroying your entire computer and anything attached to it.

It really wasn't an unaceotable answer, I just wanted to keep it open. My ASUS Probe shows that the +5V is in acceptible range. Last night I dissassembled the system attempted to do a through cleaning. This morning when I fired it up everything was OK, according to the Probe; except for one thing. It registered the +3.3V as avg. 2.94V, "Out of Treshold!!!."

Well as I warned you when a PS Fan goes bad you can get odd voltages supplied if the CPU Voltage is too Low it can still do damage to the unit and possibly even kill off the CPU as it isn't getting enough power to run correctly. At the very least if you had the PS Apart you should have replaced the fan.

I've only seen it once but a faulty PS allowed Mains Power into the case and it destroyed everything connected to the computer affected. Unfortunately in that particular as it was a Server so the entire network was destroyed.

Personally I wouldn't chance it but I'm told that it looks spectacular when something like that happens.

Unfortunantly it hapened - as you said it would! - before I could backup my data. I am going to slave it onto a neighbor's system and see if it was toasted too. Oh well
