Power supply fan weakening, programs hanging

[Fatalis]

Usually when I put my hand near the power supply fan, It's blowing warm. Today and the past few hours it has been blowing, but not warm at all. I think it is not slowing down or anything, I can hear it going pretty fast.

I am paranoid or is something wrong?

Worry about it when it starts blowing HOT.

Ok, now things are getting worse on my computer, a few hours after i noticed the above.

Now, the fan is not blowing out as much air as it used to, but still running. (This is the power supply fan, not cpu, and the power supply doesnt seem to be hot or blowing very hot)

Now, when i open any program, it takes about 30 seconds to launch it, but when its launched, it runs just fine.

When i opened a few programs at once, the computer froze for about 5 mintues, cursor wouldn't move, nothing, except for the alt+tab switch interface, but still couldn't switch programs.

Could it be the wall outlet is not giving enough power?

A while back, I installed SP2, not on windows update though.

After I installed SP2, i had problems exactly like this, which I couldn't fix at all.

However, that time, the only program that would hang and take a while to load was explorer.exe, and it used about 50-99% CPU AT ALL TIMES, so I've been using the task manager for the past few months

I have tried uninstalling SP2, did not work, actaully made things worse so i reinstalled SP2.

I am very poor and cannot afford any upgrades to this computer, please help!


I have a eMachines T1842(see, poor) 1.8ghz celeron, 384 mb ram, only thing added to the computer is the video card (radeon 7500 PCI), 256 stick of ram, and a network adapter

Running programs at time of post:
firefox.exe
taskmgr.exe
trillian.exe
vsmon.exe
svchost.exe
svchost.exe
svchost.exe
slass.exe
services.exe
winlogin.exe --I noticed this one's priority level is on high, don't know if this is default--
crss.exe
smss.exe
zclient.exe
system
system idle process

I would check inside your pc to see if the cpu fan is still running

Also, is your computer protected by a firewall (either software or hardware, or both) and current antivirus software? How about spyware, have you tried Spybot Search & Destroy and Lavasoft Ad-Aware Personal? Those are both free and may at least give some basis for knowing if there might be a spyware problem here. Spyware can cause erratic/slow behavior, so it sprang to mind.
