Long story short:

I am trying to reinstall soundmax and my motherboard, but the dvd will not load. It just flashes the light on my dvd drive. I have tried safe mode as well, same thing. I tried in my boyfriends pc (he has the same computer I have, ASUS) and after a few tries it finally loads, but wont run.


Also 3 of my external drives stopped working. Maybe same problem?

Seagate 750 gig

Seagate 250 gig

Western 80 gig


So, what file can I give you to show you what I am working with? cpuz maybe? Thank you in advance


PC info:

ASUS P5E Intel Core 2 Duo CPU E8400 3.00GHz, 3.25 RAM

With so many hardware issues, I would want to verify the power supply is working fine before doing anything else. Following is my canned text on testing supplies.

To properly and conclusively test a power supply unit (PSU), it must be tested under various realistic "loads" then analyzed for excessive ripple and other anomalies. This is done by a qualified technician using an oscilloscope or power analyzer - sophisticated (and expensive) electronic test equipment requiring special training to operate, and a basic knowledge of electronics theory to understand the results. Therefore, conclusively testing a power supply is done in properly equipped electronic repair facilities.

Fortunately, there are other options that are almost as good. I keep a FrozenCPU Ultimate PSU Tester in my tool bag when I am "in the field" and don't have a good spare power supply to swap in. While not a certain test, they are better than nothing. The advantage of this model is that it has an LCD readout of the voltage. With an actual voltage readout, you have a better chance of detecting a "failing" PSU, or one barely within specified ATX Form Factor Standard tolerances. Lesser models use LEDs to indicate the voltage is just within some "range". These are less informative, considerably cheaper, but still useful for detecting PSUs that have already "failed". Newegg has several testers to choose from. All these testers contain a "dummy load" to fool the PSU into thinking it is connected to a motherboard, and therefore allows the PSU to power on, if able, without being attached to a motherboard - great for testing fans, but again, it is not a true load or suitable for conclusive testing.

Note the required voltage tolerance ranges:

NOTE: Disregard the -5VDC reading. It is no longer used.


Swapping in a known good supply is a tried and true method of troubleshooting used for years, even by pros. If you have access to a suitably sized, spare power supply, carefully remove the suspect supply and replace it with the known good one, and see if the problem goes away.

I do not recommend using a multimeter to test power supplies. To do it properly, that is, under a realistic load, the voltages on all the pins must be measured while the PSU is attached to the motherboard and the computer powered on. This requires poking (with some considerable force) two hard and sharp, highly conductive meter probes into the main power connector, deep in the heart of the computer. One tiny slip can destroy the motherboard, and everything plugged into it. It is not worth the risk considering most multimeters, like plug-in testers, do not measure, or reveal any unwanted and potentially disruptive AC components to the DC voltages.

Note the ATX Form Factor standard does not "require" specific color coding for power supply connector wiring. It has recommendations but manufacturers often do not follow them. Sadly, many testing guides or tutorials will refer to wire color only and that can lead to improper testing.

The voltages can be checked in the BIOS Setup Menus of most motherboards but they do not reveal ripple or other anomalies either. And of course, booting into the BIOS Setup Menu requires a working PSU.

As always, before working in the interior of the computer case, take necessary ESD precautions to ensure static buildup in your body does not discharge through and destroy any sensitive devices. Unplug from the wall and touch bare metal of the case before reaching in. And remember, anything that plugs into the wall can kill. Do not open the power supply's case unless you are a qualified electronics technician. There are NO user-serviceable parts inside a power supply. If you do not have a tester or a suitable spare to swap in, take the PSU to a qualified technician for testing.

Thank you for your quick reply. I left out 2 important facts

#1 All other dvd's work fine, just the ASUS P5E motherboard dvd will not work.

#2 Those external drives were not all running at the same time. I barely ever powered on the 750 and 250 gig (maybe once every 4 months). The 80 gig was the main one left on.

The pc is only about 3 years old. Knowing all this new information, do you still think PSU?

I am also dealing with a virus I am trying to post in your virus forum, but i keep getting a network reset error retry.

Here is the weirdest, the second this reply went through, i went back to your virus forum to post my HijackThis log and got the network reset error. Am I doing something wrong?

It may not be a power supply, but as a technician, I alway like to start troubleshooting at the wall by ensuring I have good power.

If all all 3 external devices don't work, I would suspect the port.

Having said that, you should wait until you get a clean bill of health from the Malware Removal folks before making any other changes.

Thank you so much for your help. This machine is a mess and once I get this virus thing taken care of, I just found out I have 2 months left on my warranty. Which happens to be with you guys :unsure: :)

My bad :unsure: Confusing 2 different warranties and 2 different geeks :) The warranty was with GeeksQuad I believe.

I didn't mean anything by that remark. I said it lovingly :). I was hoping it was you guys. This PC has me in a panic state and I am dead in the water till I get a reply on my other post. Thanks again and I will be back to this post after they fix me up on the malware forum. :unsure:
