Please help me with any ideas on how to improve Windows 7 stability now that Radeon HD 5450 causing crashes, after several months of stability? 4 months no problem; past month, cannot run Windows Experience Index and other programs without crashing immediately. I knew the Acer Aspire X3950's power supply of 220W was lower than recommended; tried the card anyway and it worked several months without incident. PC cabinet has no room for a larger power supply; low profile doesn't allow for most PCIe cards. Updating drivers to several released during 2013 isn't helping. Last known good driver I thought was 12/2012, but after a repair installation of 7 I cannot find that driver. Should I just keep trying random driver releases of 2012 or earlier? I hate to give up on the card as it gave noticeable improvement in day-to-day display clarity of primary monitor, plus could send HDMI to flat screen TV. tx for any ideas
good suggestion; I could buy a new cabinet, a new power supply...yet I'd rather invest in a new pc because this refurb has had problems. I'm hoping I can find a fix to this, as it did work fine for several months. Do you think it's not possible, without hardware upgrades?
Crashing under load is a symptom of inadequate power or overheating. The HD 5450 can in no way overheat unless you put it in a case without any airflow, so the problem is most likely a +12v undervolt to below 11.8v.
