My girlfriend's Acer Aspire X3950 has been giving me such problems over the past few weeks despite multiple attempts to troubleshoot such that I really need any ideas as to what could be the issue.
HD 5570 (which I added in myself)
Windows 7 Ultimate 64-bit (with SP1 installed)
Everything was fine and dandy for a really long time (even after the addition of the HD 5570) until last month when it started to randomly hang every 3 or 4 days. Note that it doesn't crash to a BSOD. It just hangs.
Here's what I've tried so far:
1) I've updated all drivers to no avail.
2) I've done a wipe and a clean install of Windows and updates. The problem came right back in the very first week of the new installation.
3) Fearing that it's an issue with the PSU not being able to handle the HD 5570 or an issue with the HD 5570 itself, I have also removed the HD 5570 and reverted back to using the integrated graphics. The problem still persists. Also a new problem has arisen: sometimes after it hangs, restarting it will cause the damn Acer not to POST. I have to repeatedly restart it until it POSTs.
I'm leaning towards thinking that it's a mobo problem, though that may just be me thinking (perhaps unjustifiably) that proprietary OEM mobos are crap.
Any suggestions as to what the problem might be would be helpful.
