morning im tearing my hair out! i have fitted a new motherboard to a friends pc. the problem is if you start a game it's fine for a couple of minutes then frames drop to single figures major slowdown, then it picks back up to normal for a few mins then slows again. this is with every recent game.specs: amd 5200x2, on asus striker 2xgb corsiar dhx xms 8800 gtx 700 watt psu it's a clean install of xp (sp3 installed by standalone) i didnt install any asus software, there are no problems in device manager. 36 processes no cpu use on idle. all temps are fine. all power cables seem ok sisandra, pcwizard cant find anything amiss. dxdiag show no problems. but no games are playable and system takes a while (couple of mins) to boot latest drivers for grx card, dx up to date all openal seems ok.
what can i try, this is day3 and im going now where. many thanks.
hi, thanks for the replies, i have tried different: cpu, ram, graphics card and psu, this is day3, im trying from scatch again, if this fails i think the mobo is faulty (however it worked fine for me. it seems to be throttling somewhere and i just cant find out where, it's probably the most frustrating time i've had with a pc, im sure i've done a simple thing wrong, but cant find out what! will keep trying, thanks again
are you using a PSU calbe to power the graphics card or an exention power cable, also just because windows says there are no faults with drivers does not make it so, install mobo drivers and reinstall graphics driver
re installed from bios reset, loaded just driver from cd, installed windows and nod only, and it's still doing the same thing. it's as sli psu with dedicated pci2 leads both of which are plugged in, temps at slowdown read mobo 42, cpu 46 grx 68/70, im guessing 2psu's may be on way out, i've come to this conclusion because i've tried everything else!
costing me a fortune! it's 35 amp 12 rail psu, just installing updates praying .net update may sort, if not it's got to be hardware, all voltages are reading spot on though +- 2 either side at idle or load, the symptems are similar to running a top end game at max with 512 meg, it doesnt crash it just seems to be buffering everything, slows right down, then picks back up again, the ram volts are 1.9 so thats ok, i also ran memtest and tried other ram. i have just flashed bios. and it's still the same!!!
