no bios access on boot-up or restart

[supertramp]

I observed if i shut down pc and turn off power on power supply switch, then push power on switch on case, led fans flash for a few seconds, then turn power back on at power supply switch, and turn the system on, i get the motherboard logo and bios access, after that if i restart or from reboot, i get the multi colored screen instead of motherboard logo and bios access.

That is the wrong RAM for your CPU, AMD state here up to 3200MHz and if you have XMP or DOCP enabled the RAM will get auto OCd past what the CPU can handle and the PC fall over.

thermaltake tr2 600w

Long term you need a better PSU, Thermaltake are on the avoid list when it comes to anything less than their real high end units, some are worse than others so it would help if you tell us the exact model name or number of the one that you have.

Regarding the RAM speed, see below;

Try restoring the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" “most stable” or on newer boards “optimized” please note that if you have both the “most stable” and the “optimized” options in the BIOS you should choose the most stable" option as in this instance the “optimized” settings are a form of overclocking that can cause instability.

Save the new settings, exit the BIOS, restart the computer, test by using the computer as you normally would, post back with an update once you have done this.

You should also make sure that the Windows Power Plan is set to Balanced and not High Performance.[/color]

The info I am finding on that PSU is telling me that it is a server PSU from 2011, is that correct.

[supertramp]

quite possible yes, time for a new one!

[phillpower2]

The PSU belongs in a museum, fingers crossed for you that it has not damaged any of your hardware, it is fortunate that you do not have an add on video card else the PSU would have popped by now.

If you never plan on adding a gaming type GPU the example Seasonic 500w 80+ Bronze PSU here will suffice five year warranty is a sign of its quality.

Before making any purchase, see if you are able to borrow a known good PSU to swap in for testing purposes or alternatively, have a local tech check out your PC.

picked up a msi-A650GF power supply, should help if i get video card, any ideas on issue, seem no video when motherboard logo should appear, only full screen multicolored fuzzy, boots great after that.

[phillpower2]

That could suggest damage done to the MB because it is pre Windows as in the BIOS has not handed control over to Windows so it is definitely not driver or Windows related.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Just a brief glimpse of Speccy and we can see issues;
Operating System
Windows 11 Pro 64-bit
Computer type: Desktop

There are no system drivers shown to have been installed since Windows was and likewise there are no Windows updates shown to have been installed either and this puts you at risk of malware attack.

Once Windows has been clean installed you must then install first the MBs chipset drivers, then the storage/SATA drivers and third the graphics drivers, the drivers can either come from a disk provided by the motherboard manufacturer or downloaded from their site and saved to a flash drive etc, this is a must and Windows should not be allowed to check for updates before it has been done as more often than not Windows installs the wrong drivers or in the incorrect order and this can cause all sorts of problems.

Looking at the spec of your build you are real lucky that the previous PSU did not kill the lot of it..

For you to do, install the Windows11 drivers in the said order, get Windows fully up to date, restart the PC, run Speccy, post the new url for us.[/COLOR]
