Greetings,



i recently made a reformating of my hard drive and since then, i'M having trouble with the system stability. The computer is constantly losing speed with internet connection and reboots with a bsod. This occurs especially when i'm opening 2 internet explorer windows. The computer have been reformated by professionnals and i never had these kinds of problems before. Everything have been installed correctly with the latest drivers versions. They have tested the computer and could only find broken sectors in the hard drive so the hd is brand new. I was wondering if the problem could come from the psu. Anyone could help me with this?


Thank you.

Download Speedfan (The download link is to the right), and install it. Once it's installed, run the program and post here the information it shows.
The information I want you to post is the stuff that is circled in the example picture I have attached.
To make sure we are getting all the correct information it would help us if you were to attach a screenshot like the one below of your Speedfan results.

To do a screenshot please have click on your Print Screen on your keyboard.
  • It is normally the key above your number pad between the F12 key and the Scroll Lock key
  • Now go to Start and then to All Programs
  • Scroll to Accessories and then click on Paint
  • In the Empty White Area click and hold the CTRL key and then click the V
  • Go to the File option at the top and click on Save as
  • Save as file type JPEG and save it to your Desktop
  • Attach it to your next reply

If you have more than one RAM module installed, try starting computer with one RAM stick at a time.

NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option A

B. If you have only one RAM stick installed...
...run memtest...


1. Download - Pre-Compiled Bootable ISO (.zip). If you prefer to use the USB version then use this link USB KEY
2. Unzip downloaded /memtest86+-4.20.iso.zip file.
3. Inside, you'll find /memtest86+-4.20.iso file.
4. Download, and install ImgBurn: http://www.imgburn.com/
5. Insert blank CD into your CD drive.
6. Open ImgBurn, and click on Write image file to disc
7. Click on Browse for a file... icon:

8. Locate [b/memtest86+-4.20.iso[/b] file, and click Open button.
9. Click on ImgBurn green arrow to start burning bootable memtest86 CD:

10. Once the CD is created, boot from it, and memtest will automatically start to run. You may have to change the boot sequence in your BIOS to make it work right.

To change Boot Sequence in your BIOS

Reboot the system and at the first post screen (where it is counting up memory) start tapping the DEL button
This will enter you into the Bios\Cmos area.
Find the Advanced area and click Enter
Look for Boot Sequence or Boot Options and highlight that click Enter
Now highlight the first drive and follow the directions on the bottom of the screen on how to modify it and change it to CDrom.
Change the second drive to the C or Main Drive
Once that is done then click F10 to Save and Exit
You will prompted to enter Y to verify Save and Exit. Click Y and the system will now reboot with the new settings.


The running program will look something like this depending on the size and number of ram modules installed:

It's recommended to run 5-6 passes. Each pass contains very same 8 tests.

This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.

The following image is the test results area:

The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.

Any error message and what file type are the pics?
Make sure they are jpeg files as they are smaller in size. Your file attachment size and type are limited by the forum.

Speedfan shows your +3 volt rail is low. Possible cause of the issue.
SIW shows +3 volt good but +12 volt really bad. :)

Have you run the memtest program yet?
Is this a laptop or desktop?

Hi,



no i haven't run a mem test. I'll do it now. So you're basically saying that my psu have to be changed? I was gonna change it anyways and needed advices on which model to choose. Someone suggested me the Antec BP550 Plus 550W. It'S not a laptop by the way, it'S a desktop.

I would say yes about the PSU.
Antec is a good brand and a lot of people here suggest them. I am Partial to the Corsair brand myself.

There is some sort of bug in Windows 7 that causes +12V readings to be really off. I don't the computer would run if the +12V was at 50%. I recommend you boot into the BIOS Setup Menu and check your voltages there, or get a PSU Tester, or take it to a shop.

I don't like those 119°C and 125°C temps.

Why was it reformatted in the first place?

They have tested the computer and could only find broken sectors in the hard drive so the hd is brand new

I don't understand that. A new drive for broken sectors does not normally indicate the drive needs replacing.

Not more fans but just cable management and making sure all existing fans are running like they should with no dust build up on them.
