Hello all. I'm not sure if that's the correct forum section for my problem, but the problems started after replacing motherboard, so I'm sorry if that's not the right section. :)

A few days ago I have replaced my motherboard, from Intel D865GBF to MSI RS350M-ILSR (MS-7031) (data from Everest), since the CPU socket got damaged in the Intel board. The problem is that now the PC slows down after like 5 mins of gaming to the point where new games are unplayable, and in the older games like Q3, for example, the FPS drops by 30 or so. I turn on the pc, log into windows, run any game and it works fine for about 5 mins, and the slow down starts, huge fps drops. Restarting the game or even the PC doesn't help, but if I turn off my PC, and turn it back on after few minutes it runs fine again for 5 mins in games, and then the fps drop again. Of course everything was perfectly fine on the old board. At first I thought it was driver problem so I reinstalled windows and reformatted the drive on which Windows was installed (i have 3 drives, C, D and E, windows was installed on C so I formatted that one, didn't touch the others) but it didn't help at all. Hell, even the installation of Windows and reformatting took longer than before. I installed newest drivers for my graphics card, motherboard and everything else of course. My spec's:

Intel Pentium 4 Prescott 3.2ghz (LGA 478)
MSI RS350M-ILSR (MS-7031) motherboard
1024MB of ram
Sapphire Radeon x1650pro 512mb (AGP)
Seagate 320GB SATA hard drive
Modecom Feel 400W
Windows XP Pro

Also, I borrowed an 550W Chieftec PSU from my friend, thinking it was the case, but it didn't help, the slowdowns still occured. Please help me. Thank you in advance.

hello and welcome to TSF...
You did a good job trying to figure it out what would cause the problem...
I would do that same...

So even after reinstalling Windows you have same problem...
I would try to update BIOS to the latest version...
Report back please...

Hi vladimirb, thanks for your reply. The bios is most recent version.

Hello again...
Test your RAM modules and HDD since you got that from your old PC...
You can test RAM with MemTest86+, here is link:

http://www.memtest.org/

If you have more then one module, test it separatelly...
Before testing, clean contacts with rubber and DIMM slots with brush...

Check what make/model is HDD and download testing tools from manufacturers Web Site...
test it for possible bad sectors...
You can use MHDD, it is an excellent tool and it is free:

I would try with different PSU too... Borrow it from a friend and test your PC...

Hope this will help you mate...

Hi vladimirb. I tested both my hardrive and RAM, no errors on either of tests, both passed. And as I said in my first post, I borrowed 550W Chieftec PSU from my friend before and it didn't help. Any other suggestions? Thanks in advance.

Also, I've noticed that just moving my mouse, when in idle and doing no other thing the cpu usage goes up to 16%. I don't know if that's normal or not, but I thought I'd let you know.

Hey again...
Download SensorsView Pro from here:

http://www.softpedia.com/progDownload/SensorsView-Download-29890.html

Install and check temperatures before playing and after fps drops down and system start to slow down...

One more question:
When you switched Motherboards, did you re-apply new thermal paste???

fux0r

Hi vladimirb. I downloaded the program, but when I ran it a window has popped up saying ''sorry, not all sensors found'', and only the HDD temperature was there. Yes, I reaplied thermal paste. I was never good at aplying it though...
