Stability issues..help please?

[Sigma]

Ive been running my system oclocked for some time now and all has been fine. Recently, I've been having problems getting my system to boot into windows only after a shutdown and restart. Ive tried to tone it down but it still gives me this problem. could this be a power supply issue?

Try resetting your BIOS to default values, see if you can boot up. If not, try running Memtest86, see if your RAM has been cooked. Other than that, you could try swapping out your RAM and COU, as maybe you have cooked one of them by having them OC'd for so long.

Systems Running F@H:
AMD: [A64 3200+] [XP2800+ x2] [XP2400+]
Intel: [P4 2.8 x4] [P4 2.0] [P4 1.8] [P4 1.7] [P4 1.6 x2] [P4 1.4M] [Xeon 1.0] [Cel 1.0] [P3 ??]

I'll try that. But once the computer boots in to windows it has ran totally rock solid and I run it without shutting it off for weeks. Every program i run or have been running ive had no probs with .. its just after its been shut down for a little while do i have this probelm getting it to enter into windows.. it will post then it will just run without getting the windows login screen then the monitor will lose its signal. Ill try memtest .. thanks for the advice.

I live in NYC so its around 50F this time of year with moderate humidity.

Im in MS, and the reason that I asked is because if you were close"maybe 5C" from reaching that boards stability limits as far as heat is concerned this spring weather could be enough to have changed your average temps enough. Its certainly changed mine by around 10C but its hotter here. The first thing that pops into my head is your PSU. What does each Rail look like? 12V, 3.3V and 5V all +. The next thing that I would be suspect of is heat. Dont let the Northbridge slip by your radar. Be sure and check it also.
