Is my PSU crapping out on me?

Hi, I just bought a Aspire mod case in Dec'04 with a 350w PSU. I have noticed over the last few weeks that my cd rom drives are spinning very slowly and taking forever to spin up or seek info. I built this system and I have in it:
Asus A7N8X-E deluxe mobo
512meg Muskin ram
AMD 2700+ cpu
2 cd rom drives, 1 cdr (samsng) 1 cdrom (Liteon)
40gig hdd
80 gig hdd
Sound Blaster Live driveII
floppy.
The case has a couple lit up fans on it as well.
Voltage from BIOS readings are as follows:
Vcore =1.68v
3.3v= 3.10-3.12v
5v=4.59v
12v=12.28v
CPU temp=120F
mobo temp=86F
Is there a reference range that I can use to judge whether or not these are acceptable ranges?
Also is there a way to test my PSU and see if there is a problem? Thanks Biggy
P.S. I have tried to use PC probe and it wont load stating "can't find LMprocedure"
Also tried another program MBM5 and it gave me crazy readings like 32F for cp temp. I triple checked it and its set for Fahrenheit. So thats of no use to me as well. Thanks,

Well, if you are not sure, get a good quality power supply and check it out.
Personally.. I like the Zalman and Antec power supplies. I am using a 480W Antec in my favorite PC...
and it's powering an Asus 939 socket board (A8V) 512MB, 6600GT video card, a HD and a DVD burner.... and a few lights here or there.
It's over kill but the power supply isn't straining itself to keep up. I see your +5V is on the low side... maybe there's too much load on it.

Wouldn't hurt to invest in a good power supply... and it'll follow you around for years.

...you got me curious ... just checked out my athlonxp2200+    105F for cpu
                                                                                     100F for mobo

                                                                                      5.2 for voltage.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

The 3.3 and 5 volts are both a bit low but within a 10% tolerance.  The 12 volt line is fine.

The power supply is NOT the cause of your problem "my cd rom drives are spinning very slowly and taking forever to spin up or seek info".  All of the motor mechanisms in the drive run off the 12 volts.  Further, if the power supply was low enough to cause problems, you would be experiencing crashes and lockups and blue screens -- frequently -- which you did not indicate that you were.

I don't think that you have a critical power supply problem.

If the power spply is not the problem then what wold cause my cdrom drives to suddenly spin up very slowly if at all? Is it software related? Is there something I can test my cdroms to make sre they are not the problem?  According to the calculation of wattage from the aforementioned website, I should only need 268watts.

CD Speed is a CD-ROM/DVD benchmark which can test the most important features of a CD-ROM/DVD drive.

Tests include:

- Transfer rate
- Seek times
- CPU usage
- Burst rate
- DAE quality
- Transfer rate
- Spinup/spindown time

....maybe that'll give you/us an indication of any problems

The drives will slow down if they are having trouble reading the discs; for example, if they can't read at 48x, they will try 24x, and then 12x, and so on.  Also, software can tell the drives to run at a certain speed; for example, if you are copying from one drive to a burner, the burner will normally be run at a speed no faster than one-half that of the reader, even if it could otherwise go faster.  But the drives are not slowing down because of a lack of power.  A lack of power sufficient to cause the drives to slow down would cause the system to crash and lockup long before your first perception of the problem was the drives running slow.  And, in fact, while the drives can run at various speeds, they don't run at just "any" speed.  The data recovery circuits need the bits to be coming off the media at certain specific rates.  They will adjust the drive speed to obtain those rates, but the drive speed is still very precisely controlled, and if the CDs are being read, then the drives are running at the speed that they and the reading software "want" them to run at.

Well my cdroms had been running at high speeds (52X) or there abouts when I would put a disk in. They spin up almost immediately. I have several scrathless disks that have run awesomely in the past and when I put the disk in now the light comes on  on the drive and it takes forever for it to spin up if at all. Access times seems to take a very long time as well. It happens with both drives. I haven't changed anything as far as settings for the drives. I'm stumped.

"Why are my drives running slow" is a separate and distinct question from "Is my PSU crapping out on me"

Thanks for pointing that out Watzman... I think thats obvious..
